Many Owners owners know about the population whims, which sometimes presents unpleasant moments. And often folk craftsmen find ways to upgrade a problem node or a whole system. And about one such way of improving the launch system with your own hands and will be discussed in this publication.

General concept

Contact ignition scheme Itself is not bad, because it enjoys humanity with the advent of the first car. But before opportunity contactless ignition She, of course, is far away. Therefore, many owners of UAZ seeking to improve work power aggregate, reconfigure it.

And not only the UAZ, but also other domestic cars, for example, alterations are subjected to and, and a number of other brands and models.

Effect of modernization

What is important, the incapant and salon wiring of UAZ 31514 remains almost unchanged, and the alteration itself is characterized by installing new elements under the hood.

As a result:

1. The engine begins to work steadily in all modes;
2. Improving the start "on the cold";
3. Normalizes fuel consumption;
4. Engine power reaches passport data.

Differences of ignition systems

The main difference between two systems - in the moment of sparking:

• IN classic ignition For this, the slider is answered under the lid of the traver when contact with the pin with the withdrawal of the candle wire. In this case, the supply of high-voltage pulse occurs with increasing. It seems to be lubricated, reducing the power of the spark on the electrodes of the candle.
• In contactless ignition the switch forms a charge and gives it almost instantly When receiving a signal from the Hall sensor. As a result, the candle forms a more powerful spark. From domestic cars increased passibility A similar contactless ignition system has a Niva - see.

Note! More powerful sparking contributes to self-cleaning of the candle, because Fuel combines intensively, not leaving deposits.

What to acquire

In fact, you need to buy a bit, and if you have a good rubber and the coil, then the list of purchases will be minimal at all.

So, you need to buy:

1. Hall Sensor;
2. High-voltage wires (better silicone);
3. Switch from VAZ 08.

Tip: If your Whase has been for many years already, we recommend to buy a new rubber, a coil, and you will also need to wiring UAZ 31514 with switch connectors.

To reconfigure and operate, you will also need new scheme Wiring UAZ 31514, which is shown below in the photo, and which you can print for convenience.

You can also make the ignition system more powerful by upgrading it with two sets at once:

1. Two switches;
2. Two hall sensors;
3. Two ignition coils.

With this approach, each subsystem will be responsible for sparking at once 2 cylinders:

• First and third;
• Second and fourth.

Most often, such a serious alteration is subjected to UAZ cars, which take part in competitions, or use professional fishermen and hunters. On the video below, the engine is told about the operation of the engine with a similar system.

Tip: If you are operating your UAZ 31514 in everyday lifenot associated with extreme, it is sufficiently limited to alteration with one set - it is so easier to serve it. After all, on domestic all-terrains is used.

Rework

Actually, the work itself comes down to the redistribution of a traver, which will no longer be high-voltage part - forming high-voltage pulses for it will be an electronic switch. On the photo presented below shows the location of two sensors immediately.

Pay attention to the form of the contact plate:

• It has concealed ends - sensors are located vertically;
• Smooth - sensors are attached horizontally.

Both the one and the other option - workers, it all depends on the design of the traver. In the future, you will only have to adjust the ignition. The instruction is simple - you must remember that the beginning of sparking begins when the edge of the plate turns out to be in the center of the Hall sensor.

The procedure is as follows:

1. Machine the crankshaft until the piston does not reach the NMT in the first cylinder;
2. Turn the trimmer body until the contact plate is in the slot of the sensor;
3. Carefully tighten all the fastening screws to eliminate the backlash.
4. Run the engine.

Finally

If everything is done correctly - the ignition system will work stably and without problems. And your car will improve your operating parameters. The price of the question is a penny, since you do all the work yourself. Good luck on the roads of general use and off-road!

Refinement of the standard electronic ignition (switch 131)

I gathered an unworthy scheme. Put the Volgovsky 131th switch and the "eight" coil with a short-circuited core (they say that the most powerful). In this case, the variator did not need (the switch is designed to work without it).

A year and a half ago I came across an article (in my opinion, in the magazine "SP"), the author of which categorically argues that the use of the eight coil 27.3705 and its analogues leads to a rapid overheating of the 131st switch.

Why is it better to put a switch 131.3734 (90.3734):
1. This switch does not need an additional resistor (variator) - i.e. No energy loss into empty on this resistor.
2. Based on the analysis of these switches, you can choose a really good device (Kaluga, Art. Oskol).
3. The scheme is simplified, i.e. Less chance of refusal.
The effect achieved:
The engine runs on turns starting from 500 (!) - As a sewing machine! No failures, failures - rocker and screaming! (To the question that 151 does not hold turnover - the ignition is in the ignition, it turns out!) The noise of exhaust, which has always been significant, has decreased to the level of the passenger car! (on XX). The overall noise of the working machine (3 l. Engine) - fell in front of her eyes!

Electric schematic scheme Switch 131.3734 (from the "Technical Support of Volgazes", the switches of 90.3734 and 94.3734 are collected along the same scheme):

• R1 - 1K; R2 - 6,2K; R3 - 1.8K; R4 - 82; R5 - 10; R6 - 300; R7 - 47K; R8 - 3K; R9 and R13 - 2K; R10 - 0.1; R11 and R12 - 330; R14 - 10K; R15 - 22K.
• C1, C2, C6, C8 and C9 - 0.1MKF; C3, C5 and C7 - 2200PF; C10 and C11 - 1MKF.
• VT1 - KT863; VT2 - CT630B; VT3 - KT848A.
• VD1 - KS162B; VD2 - od522; VD3 - CD212; VD4 and VD5 - KD102.
• Chip KR1055HP1 or KS1055HP1.
• The VT1 transistor on parts of the switches is not installed.

More on the replacement of the switch by 131 cm. In the article "Volga Podlers" on the website "driving". "Hybrid" ignition (cam timer + electronic switch and coil)

There is an easy way to increase the efficiency of contact (cam) ignition (due to the use of elements electronic ignition) And increase reliability. I installed the switch and the coil from 2108, the converter launched (cams are connected to the eight switch instead of the Hall sensor). If the switch fails, switch the wire from cams to the old coil and can be further ride on the fist of the ignition. Works for more than 3 months, mileage 2000 km. [IN. V. Mikhailin] Electronic ignition with Hall Sensor

There is an electronic ignition ATE-2 with a Hall sensor. The kit will be astate from the switch 76.3734, the 5406.3706-05 traver (operating experience and tips on the track setting), B-116 coils and a beam of wires with connectors. The rubber immediately disassembled - it will make Pts. Unusual - a rigid through axis on 2_x supports, the centrifugator controls the shutter turn, and the vacuum is the rotation of the Hall sensor. Just and reliably. Cover- white. It is all in the UP (straight in the store, a little left of the entrance) 900 rubles (by 06.2000), i.e. A little cheaper than the standard set (131th com. + Trambl) for UAZ Yes + free adjustment on the stand. [Mahno]

Easily redid all electronic ignition by 31519 with a 3-liter engine.
1. The regular electronic ignition distributor is replaced by mechanical P 119-b;
2. The regular ignition coil is replaced by B-117 A;
3. The regular switch and the variator are simply removed;
4. In principle, the above alterations are quite enough to overall the reliability and ignition power, but I also installed the Pulsar electronic multi-level ignition unit (option for the classic) with an octane corrector, anti-theft and emergency mode.
The entire set kit reliably operates for more than two years and provides reliable engine launches after long-term parking lots in crude and cold weather (this winter started at -30 degrees). In addition, there is a tangible savings of gasoline (in full accordance with technical description On the "Pulsar") due to the overall increase in the power of the spark and afterburning the combustible mixture in a multi-track mode. I did not produce accurate measurements of gasoline consumption before and after installation, but subjectively gasoline savings on the track amounted to at least 15%.

Brothers Wazist! Do not repeat other people's mistakes! Miracles are only in fairy tales. Contact system Ignition (including in native form and paired with an electronic unit) provides a less stable spark as in time and in power. Where to ride savings? It makes no sense to set fire already a burning mixture in a multispore mode. For my car with a regular contactless Ignition System Start with an intelligence in -30c - rate. [Yuri Zhilin] What could be? When checking a stroboscope, the spark is visible in sparking is unstable, with some intervals. Failure somewhere once every 4 seconds. Replaced the coil to a new one and the switch is disappeared ...

I had the same thing on the usual ignition. The very first checking the candles, most likely some one flew out and the car simply Troit. Check out the alternate wires from the lid of the trambl. I found this way. Yes, and see what candles are standing, the best put A11.

The question is not as simple as it seems at first glance. Possible plenty of causes of this phenomenon. Unstable work The stroboscope itself first. The composition of the mixture (rich, poor), the presence of unstable contacts in electrical equipment (including in the ignition lock), the leakage of high voltage through poor insulation and dirty, wet surfaces. Application in electrical equipment of interference resistors and high-wired wires. If the contact system of the ignition is possible, it is possible to wear bearing in the ignition distributor or an incorrect gap between contacts. The list is not complete, looking for and unite :-) [Yuri Zhilin] Recommendations for configuring a traver

Answer A. Ermakova (Makhno) on the letter Andrei Petrukhina

1. Nominal turnover of XX Motors UAZ and Gas are essentially different (respectively, 500-600 and 800-900 rpm), which is due, primarily the design of the CAT - on UAZ (mainly) partially synchronized - and "stick the transfer" on 800-900 0B (as on gas) - very problematic. And when considering the characteristics of the centrifuges, it is immediately visible - the collar of graphs from the axis of "revolutions" on the UAZ takes place earlier than gas. Here is one, but a significant difference.


2. We look at the first sections of the same graphs - from 0 to 1500 revolutions (the most "workers" turns!) And we see that for the UAZ 1st segment there is more than hollow, rather than at the gas - it is again reflected in the pull "on the nizakh ". 3. But the biggest and most serious difference is Har-Ka Vacuum - I felt on the owns. Schucket - and then he was measured - the full row of the Vacuum corrector's rod in GAZ-4-4.5. mm, and uaz- 7 !!! And the spring is much softer (1.5 times!)!

In general, in my opinion, without serious refinement, the Gazovsky TR-R on UAZ is not applicable. Adaptive engine control system (ASUD, "Mikhailovskoe ignition")

Yuzay him about 4 months - nothing has changed radically. A number of advantages were felt - the engine works smaller, but the fuel consumption did not change significantly (although I expected it). It is possible to seal the ignition system completely. Some special increase in traction did not notice. Perhaps this is the consequence of the fact that I also brought to mind to the mind - I chose the characteristic of the centrifugal regulator with springs. To my some surprise, the ASUD system does not choose the optimal ignition angle - the ignition sensor can be done before or later. Those. The procedure for placing an angle of detonation remains. In addition, I had to repair it almost immediately - there was a printed circuit board. Summarizing this way - this system allows you to pay the ignition system significantly less attention, increase its buoyancy in water. But do not wait for cardinal improvements. [Chif]

Automatic octane corrector is automatic system Optimization of the ignition advance angle. Made in the form of a console electronic system Ignition of gas gas with ZMZ-402.10 engine (4021.10, 4025.10, 4026.10, 410.10). It is also possible to install this option on the CSDs of the UAZ brand with engines UMP-417, 421.

The experience has not yet been accumulated. 03.2003.

You put the slot of the oil pump under 30 degrees, in relation to the axis of the engine, and the slot in the leg of the traver - under 45 degrees. And carefully stuff the leg.

Tilt the engine (car) so that the drive hung vertically, and lower down in accordance with the instructions.

Extreme case. Remove the oil pan and fill the shank below. Interchangeability of spark plugs

Data is given by the CN. V. V. Litvinenko "Electrical Equipment of Cars UAZ". VR, 1998. The gap between the electrodes of the candles to be established in accordance with the requirements of the UAZ instruction (0.8 - 0.95 mm).

Recommendations for the choice of spark plugs

It will be better if you put the A14 candles instead of A11. The temperature of the electrodes and the insulator (around the central electrode) should be 500-700 C. less and touches Nagar, more - there will be a caliling ignition (and the other is not suitable anywhere). 11, 14 or 17 is a calil number than it is more, the fact that Candle is colder, that is, the heat is faster from the insulator and the electrodes to the block head and, with other things being equal, the temperature of the candle will be less. It is measured as: the candle is put on a special engine and the full load is given - the number of seconds through which the calil ignition appears, and there is a calil number of candles.

For UAZA-11, for Volga-14 on the same gasoline and with the same compression ratio, and the difference in the engine temperature is 70 and 80 degrees. And there is still a very important thing in the marker of the candle - this is the letter "B". It means that the insulator of the central electrode "acts" in the combustion chamber (A11 isolator is deeply drowning). The protruding insulator is better blown away and therefore is better cleaned from Nagara; Such a candle dries up much faster if you pour it. There are candles with bimetal, platinum and other electrodes - all this to choose thermal regime at different loads.

The most important thing is that it should be - put A14B - from Nagara is cleaned better, the probability of a caliling ignition is less. A17V I do not advise - problems may arise when long work on the idling Or with short trips in winter. I have an A14V- on an insulator there is no Nagar at all.
Previously, A-11 stood, and with the replacement there was no change, so it's all on an amateur and for a good car there is no difference.

A-11 put under 76. Volga and UAZ used to go with a degree of compression 6.7. Now UAZ go with a compression ratio of 7.0. So it makes sense to look after A-14. Letter d, of course, does not fit us. When I had a head under 76 gasoline, I put the A-14 and Candles on the advice of the chauffeurs and the candles were brown. As far as I know, this is normal

I have a candle A-11 from Engels, through 16 kkm candles were ideally, on the central electrode there was not even a V-shaped burner. And the fact is that after a long ride, I do not immediately turn off the engine (it is prescribed to work on H.x.- It works 1 min on H.H.), and then it was prescribed for piston aircraft engines (!) I burn candles, increasing turnover to 1500-2000 a few seconds. And only then, smoothly dropping to H.kh., turn off the engine. The procedure is simple, but in this case the life of the candle life will be 50000 km at a minimum.

I do not agree! Where does the Candle Resource begun to increase the load on it? Modern carburetors provide engine operation without nagar formation on candles in all operating modes. In addition, using this method, you for every 400 km of the urban cycle, you will supply extra gasoline to the amount of equivalent set of 4 candles. Add high wear engine here. [Yuri Zhilin] Forkarm candles, are they needed?

The engine works much softer. More differences could not be felt. Probably they are, but they need to fix them already :).
The main thing is not worse. And these candles are not real forkarmed (from a scientific point of view). [Radomirych]

The idea is that the mixture is not sparkling, but a flame from an additional combustion chamber. This chamber needs a mixture of another composition, and the special. carburetor. Again, the ignition must be put earlier on an unknown value. And this, damn, like his ... (Draver - (y)) Well, which increases the ignition advance an ignition advance an increase in the former to work in a different way. The article in the dawn was about this head of the block, there you can read and think if the candles can replace this wonderful device. I think there is no.

SUMMARY: Do not let yourself have a fraudsters! "Forkarm" candles - a way to deceive and rob owners of the UAZ, and also spoil our favorite car. [Yuri Zhilin] How to check the performance of an induction coil without installing it on a rubber?

Do you check the batteries? - Language! So here is the same! Better, of course, a voltmeter - with a sharp cutting of the roller hand should be at least 2 V between the case and the terminal. Only a rag of the protrusion, and then in the mouth will be afraid! [Chif] Alteration of a traver on contactless forces

I decided as it (broke the shaft, and then the luxury) to change the traver, stared at shops in search of non-contact, and then suddenly thought. - Why buy if you can make "your" from the old R-119 and remedies.

After passing a bunch of documentation about the types of contactless sensors used in the industry chose the optocouple as the easiest. The optocoupler squeezed out of a dead mouse (found that the most reliable), installed, bay with epoxy on the metal plate and brightening to the fastening of the springs of the interrupter lever. The LED subscribed through the resistance to 10k. The photodiode is polarly included between the adhesive of the switch D and +. Plus was taken from the same switch. As a curtain applied a round plate of aluminum with cut-off windows.

The whole system goes around 6 months. What winter, that in the summer is one light :). Get up better. Idle machine Holds confident. Overclocking and riding a tension - normal. Fuel consumption remained in the same condition - 13-14 l / 100 km.

BUT...
Next, some glitches got out. Spark is not just powerful - but very powerful. Punches regular wires. Changed to silicone. After a month of driving, the electorates are very burned in the A14 candles of the unknown Russian manufacturer. Put NGK. When switching on the load (headlights, etc.), the engine "Chishel" (blinked LED: (). Refigured the driving out of the LED from the KR142EN5A and resistor stabilizer 510. Helped. Next, I am thinking about replacing the switch to microcontroller sprouting, the benefit of detonation sensors are already released for Injector engines.
Permyakov Ilya
Do I need an emergency vibrator

The emergency vibrator gives continuous sparking, regardless of the position of the pistons, as a result, the mixture flashes before the required torque, in detonation mode - the result is similar to continuous sledge hammer blows over the pistons with a frequency of 500 to 2000 times a minute in each cylinder. What do you think, what will be the result? The overhaul with the replacement of broken rings, molten pistons, burned valves, bent crankshafts, handled the walls of the cylinders.
Thinking over the question - why is such a dangerous thing in the car - I came to the conclusion that, perhaps, the emergency vibrator was set by the military so that the car after the nuclear explosion (when all the electronics arises, incl. Switch). I think that if it comes to the nuclear war, I will still be anyway - the car can continue the movement or can not.
If you want to increase the vitality of the car, then you have a better saving switch with you (and the backup stator of the traver - (y)). [Yuri Zhilin]

I felt some "twitching". After the stop at the refueling could not get started. Another symptom - when the ignition is turned on, the voltage arrows immediately takes the fix. Position (when everything is fine, it is after a couple of seconds after that (the coil is charged?) Should still go to the right). Replacing the switch situation has not changed. Dipped notorious wiring in the rubble. An attempt to increase it led to the cliff of a piece. A spare track, naturally, no (it is necessary to carry with you the "stator" to the reserve). Shops do not work (Sunday, late evening). Recruited the emergency vibrator. About a hundred kilometers on it drove. The car fled 80-90, though it ran down when trying to accelerate sharply. Consumption - within reasonable limits. In the legs of the passenger, the whole road was distributed in the invigorating squeak.

Well just one in one! But with the emergency vibrator I was waiting for a bummer. I had a vibrator from the factory faulty. How far he flew away after I found out. And then a few hours with a cable in the hands. Now I drive a stator coil to a person ... Still, it is better to carry duplicates with you, it's more reliable.

The ignition coil B7-A is a transformer that converts low voltage of the primary chain into high voltage of the secondary chain required to obtain a spark between the electrodes of the candles and the ignition of the working mixture in the engine cylinders.

Attaching the ignition coil into the electrical equipment chain is shown in Fig. 2. In the primary winding of the coil, the current passes through the added resistance, which when starting the engine, the starter turns off automatically, and the current enters the primary winding, bypassing it, which is reached the amplification of the spark and facilitating the engine start.

The ignition distributor of the RZ-B is mounted on the left side of the cylinder block and drives against the oil pump roller.

The ignition distributor is designed to interrupt the low voltage current in the ignition coil circuit, the high voltage current pulse distribution of the engine cylinder cylinder candles of the mixture of the mixture, depending on the number of revolutions and the engine load.

The dispenser interrupter consists of a fixed contact plate, a rolling pin lever and a four-gamped cam, which, rotating, blurs the contacts, racing the arms on the lever pad. The gap between the interrupter contacts is regulated by an eccentric. In parallel, the contacts include a CN-4 capacitor with a capacity of 0.17-0.25 microf.

The high voltage current distributor consists of a rotor and covers with electrodes that are connected by wires with a coil and candles. The rotor of the distributor during rotation transmits high voltage current pulses from the secondary winding of the ignition coil to the candles in accordance with. Procedure for the work of cylinders.

The distributor has a centrifugal and vacuum regulators that automatically change the ignitions of the ignitions of the octane corrector for manual adjustment of the ignition angle depending on octane number Gasoline used.

The centrifugal controller changes the ignition angle depending on the rotor of the engine (or the distributor roller).

The vacuum controller changes the ignition angle depending on the engine load (the vacuum in the inlet tube).

The work of the vacuum regulator of the ignition advance: A - the discharge in the carburetor is small; b - discharge in the carburetor Veliko: 1 - tube fitting from the carburetor; 2 - adjusting washer; 3 -prot; 4 - lid vacuum regulator; 5 -Diaphragma; 6 - the case of the vacuum regulator; 7 - screw fastening of the regulator; S - thrust; 9 - pin; 10 - mobile panel of the interrupter; 11 - Contacts; 12 - arm arm; 13- File

The octane corrector provides a change in the ignition angle within + 10 ° at the corner of the rotation of the crankshaft.

The Ignition Candles A14U of an unbearable design have the length of the whip of the housing 14 + 0.5 mm and the metric thread M14x1.25. Clearance between candle electrodes 0.8-0.95 mm.

When adjusting the gap between the electrodes of the candles, it is necessary to bend only by the side electrode, since the insulator of the candle is bursting to the central electrode.

The ignition switch and starter of the VK21-K (Fig. 150) is used to turn the current in the primary chain of the ignition system and to turn on the starter and the radio. Installed switch on the instrument panel.

On the plastic base of the lock switch, the AM (ammeter) terminals are placed, KZ (ignition coil), st (starter), etc. (receiver). The AM terminal is under constant voltage.

When the key turns into the first right position, the AM terminal is connected to the KZ terminals, etc., ignitions are activated by the chain of control devices, a wiper, a radio receiver, a windshield blower fan, a cab fan and body heating. The radio receiver is only installed on the UAZ -452B bus.

When the key turns into the right extreme position, the AM terminal is connected to the KZ terminals and the ignition and the starter are turned on.

Maintenance

At T-1 it is necessary:
- check the reliability of electrical connections and fixing the ignition system devices;
- Lubricate the distributor roller by turning the cap of the cap oil. Throw one drop of oil used for the engine, on the axis of the interrupter lever, 1-2 drops on the cam flushing and 3-4 drops into the cam sleeve (after removing the rotor and filter under it). When lubricating the cam and the axis of the interrupter, it is necessary to ensure that the oil does not fall on the contacts of the interrupter.

At TU-2, in addition to the works provided for by that-1, perform the following works.

Check the condition of low and high voltage wiring and clean them from dust and dirt.

Finding the spark plugs, clean them from the car and adjust the gaps between the electrodes.

Inspect the contacts of the distributor, remove the dirt and oil from the contacts, wiping them with suede, slightly moistened in gasoline. Then wipe them with a clean dry suede or a tissue that does not leaving the fibers on the contacts.

The burnt or oxidized contacts should be carefully cleaned with a special abrasive plate included in the driver's tool kit, or a shallow glass skurt.

After stripping contacts, it is necessary to wipe the suede, slightly moistened in gasoline, and establish a normal gap between them.

Check the dipped gap between the interrupter contacts and, if it is more than 0.05 mm differ from the nominal (0.35 - 0.45 mm), adjust it.

To adjust the gap need to turn crankshaft The engine with the handle so much so that the interrupter's cam completely dispelled contacts. Then weaken the screw fixing the fixed contact plate and, rotating the screwdriver head of the adjustment eccentric, shift the plate, and with it, and a fixed contact in the desired direction before receiving the desired gap. After that, tighten the screw and check the gap to the dipstick again.

Fig. 9. Checking the interrupter spring tension

Check the lack of hot lever on the axis, for what to squeeze the lever with your finger and release it. The lever released must quickly return (under the action of the springs) and contacts must be closed with a click.

If the closure did not happen or the sluggish contact of the contacts occurred, it is necessary to eliminate the jealous and adjust the tension of the interrupter's spring within 500-700 g, removing the lever and bending the spring in one direction or another, as needed. Spring Tension The interrupter lever is checked using a spring dynamometer, as shown in Fig. nine.

Once a year, but no less often than in 25,000-300,000 miles of running and, if necessary, repair the distributor in the workshop. In this case, the distributor is disassembled, inspect all the details and, if necessary, replace.

When the dispenser is bulkhead, lubricate all the rubber parts, and the cam filhes are impregnated into the oil and pressed.

Remove the fixed panel of the breaker, wash the ball bearing and lay a new one in it. consystem lubricant LZ-158 or cyatim -201. Before panel formation, the ease of rotation of the ball bearing is checked and, if necessary, additionally turn its outer ring to the elimination of the healing.

Check the amount of carbon resistance; It must be within 6000-15 000 Ohm.

After 40,000-50,000 km of the car run in the case of a large radial backlash of the distributor roller, causing violation of spar formation, replace the roller bearings of the distributor.

The main malfunctions of the ignition system and how to eliminate them

The frequently encountered dispensers include: violation of the normal gap between the interrupter contacts, the oxidation of the contacts, the wear of the textolite protrusion lever of the interrupter, the capacitor insulation breakdown, the disorder of the insulation of the cover and rotor of the distributor, decrease the elasticity of the springs of centrifugal or vacuum control regulators, the discharge of the vacuum regulator.

Violation of a normal gap between contacts, as well as their oxidation causes interruptions in the engine operation.

To troubleshoot a malfunction, it is necessary to clean the contact of the interrupter, and then adjust the gap between them, as described above.

Wear a textolite protrusion lever of the interrupter leads to the fact that it becomes impossible to increase the gap between the contacts to normal (0.35 - 0.45 mm) of the magnitude. The lever with a worn protrusion is replaced.

When testing the capacitor isolation, the engine begins to work with interruptions, and then stops. The contacts of the interrupter are greatly overtaken. Faulty condenser replace new.

Violation of the insulation of the cover and rotor of the distributor entails the appearance of interruptions in the engine operation. Faulty lid and rotor are replaced.

The decrease in the elasticity of the centrifugal regulator springs is accompanied by the appearance of strong detonation stuffs when the vehicle is moving (not only during acceleration, but also when moving average speed). In this case, it is necessary to increase the tension of the springs by sweeping their racks, after which check the distributor on the SPZ -6 booth.

A decrease in the elasticity of the spring regulator springs causes a change in an increase in the angle of a ignition advance at medium and large engine loads, which is accompanied by the appearance of detonation stuffs. In suspected of a decrease in the elasticity of the spring of the vacuum regulator, the distributor must be checked on the SPZ -6 stand. To increase the elasticity of the spring, install an extra washer between the spring and the fitting. After that, the vacuum regulator again check on the stand.

The violation of the tightness of the vacuum regulator usually occurs due to damage to its diaphragm. In this case, the regulator ceases to increase the ignition advance on small and medium loads, as a result of which the fuel efficiency of the car is worse. The tightness of the vacuum regulator is checked on the SPZ -6 stand. In the absence of a stand, the tightness of the vacuum regulator can be checked as follows. Remove the regulator from the distributor to bring air under the pressure of 3-4 kg / cm2 and immerse in water. At the same time, air bubbles should not be released at the site of the hull and nut connections and at the location of the lever.

The ignition coil malfunction includes insulation tributes and intersensional closures of primary and secondary windings, cracks in the lid, as well as the abnormal resistance. With breakdowns of the insulation windings, the engine stops working and it fails to start. With inter-touch closures, interruptions occur in the engine. When an additional resistance is blocked, the engine is easy to start starter, but the starter turns off the starter immediately.

Dropped additional resistance must be replaced. Faulty ignition coil replace new.

Faults of spark plugs. Any of faults of spark plugs (violation of a normal gap between the electrodes, the deposition of a large nagar layer on the housing and insulator, the appearance of cracks on the insulator) entails the occurrence of interruptions in the engine operation. The non-working candle is detected by alternately disconnecting each candle (by removing the carbetic tip) when the engine of the crankshaft operating on the lowest possible turnover of the engine. Disabling the faulty candle will not affect the uniformity of the engine. When disconnecting a good candle, the uneven operation of the engine will increase.

The faulty candle must be turned out, clean and check on the Garo model 514.

Instead of a faulty candle, you need to screw the new, checking the pre-gap between its electrodes. When installing a candle in place under its body, a copper gasket must be installed.

The gap between the electrodes of the candle is checked by round affairs available in the driver's instrument. At the same time, it is impossible to pylize with a flat probe, since it is not "" in the deepening of the sideline, the candles sampled on the process of its work.

The ignition switch is very durable and, as a rule, works without repair or replacement for several years.

Installation of ignition

Ignition of the engine must be installed with great accuracy, since even with small errors in the installation increases sharply, the fuel consumption increases, and the engine power decreases.

The order of operations when installing the ignition is next.

Remove the distributor cover and rotor and check the gap value between the interrupter contacts. If necessary, adjust the gap. Put the rotor in place.

Remove the first cylinder candle and closing the first cylinder candle with a finger, turn the engine shaft by the starting handle before the start of the outlet of the air from under the fingertip it will occur at the beginning of the compression stroke in the first cylinder.

After making sure that the compression began, carefully turn the engine shaft before the coincidence of the hole on the pulley with the pin.

Smooth setup nuts Set the Octane-corrector scale to zero division.

Loosen the screw fastening of the interrupter housing and rotate the dispenser body counterclockwise so much so that the interrupter's contacts are closed.

Take a portable lamp and using additional wires to connect one of the wires to the mass, the other to the low voltage terminal on the coil (which is attached to the wire that goes to the distributor).

Turn on the ignition and rotate the dispenser case clockwise until the light bulb flashes. Stop rotation of the distributor should be exactly at the time of flashing the light bulb. If it failed, repeat operation.

Secure the casing of the distributor with a screw, put the lid and the central wire in place.

Check the correctness of the connections of wires from the candles, starting from the first cylinder. Wires must be attached in order 1, 2, 4, 3, counting counterclockwise.

RIC. 10. Determination of the upper dead point

After each ignition installation and after adjusting the gap in the interrupter, you need to check the accuracy of setting the moment of the ignition of the combustible mixture, listening to the engine operation when the car is moving. Refiguring the ignition installation can be made by Octane-corrector, without weakening the fastening screw. To do this, it is enough to rotate the smooth setup nuts, unscrewing one and shrinking the other.

Moving the arrow to one division of the Octane-corrector scale corresponds to a change in the ignition installation by 2 °, counting on the crankshaft. When turning the dispenser's housing counterclockwise, the ignition installation will be later clockwise - earlier.

The most advantageous ignition advance will be this, in which during a sharp overclocking (full opening of the throttle) of a fully loaded car on a horizontal road with an initial speed of 30-35 km / h in direct transmission will hardly listen to the unit detonation stuffs in the engine cylinders. If there are no intense drive of the car the car, it means that ignition later; On the contrary, the appearance of a number of consecutive distinct knocks indicates too early ignition.

TO Atientary: - UAZ

The ignition procedure on the UAZ depends on the scheme that has distinctive features For each type of ignition system.

How to set ignition

In order to properly adjust and set ignition on the UAZ, it is necessary to follow the sequence of actions, which is provided in the repair manual.

Before you start adjusting the ignition system, you must install vehicle On the observation pit or a special platform for repair work and turn on the handbrake. Vehicle wheel mechanisms must be fixed by a stopper or focus. The power unit must be disconnected.

After that, you can proceed to the ignition installation. To do this, it is necessary to fix the piston of the first cylindrical element in the position of the highest dead point. At the same time, it is necessary to check that the hole on the crankshaft pulley coincides with the pin on the cover of the camshaft gear. It is necessary to slightly lower the mounting bolt, located on the plate, to the housing of the distribution equipment sensor.

Then you should remove the cover from the distribution device and turn the crankshaft by 180 °. Octane-corrector must be in a zero position. Then it is necessary to tighten the pointer to the housing of the distribution mechanism sensor so that its position coincides with the ricke of the Octane-corrector.

After that, we configure the slider, rotating it counterclockwise. This will help eliminate the gaps in the drive. When the point in the stator coincides with the label of red, you can fix the plate with a bolt.

Then you need to install the switchgear sensor cover and check the correctness of the installation of the ignition lines according to the procedure for the operation of cylindrical mechanisms (1-2-4-3). It is necessary to count in the direction counterclockwise. The ignition setting on the UAZ is completed.

If, with an increase in speed up to 50-60 km / h, the driver will feel short-term detonation, which means that the procedure was performed correctly.

In the event that there is no detonation, you need to increase the advance angle, taking the sensor clockwise.

How to check the ignition coil

Check is required in the following cases:

• The mechanism does not stall when the ignition is turned off.
• There was a short circuit.
• Candles of ignition systems came out.
• The coil is heated, which is why the system is overloaded.

In order to check the ignition coil, you need to turn off the power unit and open the hood. Then you need to find the coil. To do this, it is recommended to follow the wires that lead from the distribution mechanism in reverse side. After that, you need to disconnect 1 high-voltage wire from the spark plug. Before the procedure you need to wait until the engine is completely cooled. This may require 15-25 minutes.

Then you should dismantle the candle with a special nozzle. It must be done carefully and ensure that the garbage does not get into the hole, because This will cause a malfunction of the power unit. You need to connect the wire back to the candle. To perform this operation, it is recommended to use pliers with insulated handles.

After that, you need to touch the threaded side of the candle to bare metal. With the ignition on, all the elements of the electrical equipment of the vehicle will start working, it means that the coil is functioning properly. Driver performing repair workmust see a spark of blue. If it is not, it means that the system is faulty. If the spark of orange color occurs, it means that there is an insufficient amount of voltage. The reason for this can be bad contact, weak current or defects of the coil housing.

Another way to check the ignition coil connection:

1. Remove the coil from the car. To do this, you need to disconnect the wires of distribution equipment, remove the fasteners from the coil body using the wrench.
2. Determine the state of the mechanism using an ohmmeter. You need to touch the primary winding to the primary winding, touching 2 contacts at the same time. After that, you need to measure the state of the secondary winding and compare the obtained indicators with the factory that is in the repair manual.

Before starting work, it is necessary to establish transport to a flat surface and fix it with special locking devices. While checking the device, it is recommended to wear protective clothing (mask and glasses, as well as gloves).

How to connect ignition lock

Replacing the ignition lock involves disassembling the old and installing a new mechanism with its subsequent connection. To remove the old castle, you will need a cross and flat screwdriver.

Procedure for dismantling the old castle of the transportation system:

1. Remove the fasteners from the bottom facing panel of the steering column.
2. Insert the key into the lock and set it to the zero position at which the steering mechanism will be blocked.
3. Remove the steering column.
4. Unscrew the fastening bolts of the ignition lock.
5. Insert a flat screwdriver into a small technological hole and click on the retainer that holds the lock.
6. Push the castle from the landing place.
7. Disconnect all wires of the system.
8. Install a new lock, connect the wires and collect the mechanism by performing all actions in the reverse order.

All wires are connected in the direction of the clockwise direction.

To the output number 50 you need to connect the wire of the red color, which is responsible for the stable operation of the starter device.

To the output number 15 you need to connect the wire of blue color With a black stripe, which is responsible for heating the vehicle salon.

To the output number 30 pink wire is connected, and to 30/1 - brown.

The INT connector must be connected to a black wire that is responsible for the work. overall lights and headlights.

After all the wires are connected, you need to connect the battery terminal. To the top of the terminal, the black wire must be connected. Then you need to start the engine and check the health and efficiency of the entire ignition system. First, it is recommended to check the operation of electrical appliances, and then the serviceability of the starter mechanism.

If all the wires are connected correctly, then with a zero position of the ignition system, all elements of electrical equipment will be disconnected. When you turn the key to the first position, the operation of the system that controls the engine is activated internal combustion, generator installation, headlights and locking signals, as well as washers and glasses cleaners. When you move the key to the second position, the starter is triggered, the rod of the anti-theft system is shifted and removed when the position is changed.

If this did not happen, it means that the wires are connected incorrectly. It is necessary to disassemble the mechanism and repeat the connection procedure.

Ignition scheme

The scheme depends on the type of IAS-3151 ignition system. In order to correctly set the contact, contactless, electronic or underwater ignition with your own hands, you need to use the repair instructions.

Contact

Connection diagram of the contact system includes such elements as:

• Lock. It is located on the steering column housing and is necessary to control the current flow between the battery of the transport and ignition.
• Battery. At the moment when the engine is disabled, the power supply of the entire electrical equipment is the battery. It complements the level of electricity, which is generated by a generator set, if it issues a voltage below 12 V.
• Switchgear. It sends a high voltage current from the coil through the distribution mechanism handle in turn to each of the system's candles.
• Capacitor. It is located on the camshaft housing and warns the appearance of a spark between open contacts of the system, protecting them from burning.
• Spark plug. The current of high voltage moves along the central electrode of these mechanisms. Between the central and side electrode, a spark appears between the central and side electrode, which sets on fuel fluid in the cylindrical device.
• Drive unit. The distribution mechanism is equipped with a direct type of drive from distribution Vala.. The speed of rotation of such equipment is 50% of the rotational speed of the crankshaft.
• Centrifugal regulator. It is necessary to install the desired angle of fooling, depending on the rotor of the motor. This mechanism includes cargoes that rotate, affect the plate with the interrupter contacts.
• Coil. Its design includes 2 isolated winding wires that are wound on the core made of soft steel. The process of compressing magnetic fields around the primary winding forms a high voltage current in the secondary winding passing through the distributor to the Ignition System Candles.

When the driver turns the ignition key, the low voltage current of the battery goes to the primary winding of the coil. After that, it begins to form a magnetic field. Due to the rotation of the power unit from the starter, the contacts of the cam interrupted device are opened. At this moment, the magnetic field begins to disappear, and the power lines and windings turns form a high voltage current. The pulse appeared turns onto the cover of the distributor housing, and the spark charge flames the fuel and air mixture in the cylindrical device of the motor.

Contactless

In order to establish the moment of contactless ignition on the UAZ, it is necessary to prepare the following tools:

• wrench kit;
• crosshead screwdriver;
• stroboscope;
• protective clothing in the form of glasses and masks;
• retaining mechanisms for wheels.

Before you begin to connect, you need to wear protective clothing and install the vehicle on a flat surface and fix its wheels using special stoppers.

First you need to put risk on the lid of the valves and combine all tags. After that, turn out the candle of the first cylindrical engine mechanism and remove the cover from the main distributor. If you pull out the first cylinder candle, you can track the stroke of the piston part of the motor.

Then you need to insert in clasple A long screwdriver and turn the crankshaft for the ratchet clockwise by setting it to the position of the highest dead point. This will help push the screwdriver back from the well. The label on the pulley should be put up opposite the long risks on the case of the power unit.

After that, you need to weaken the contact nut, which presses the rubler to the cylinder block. Rotating the housing, it is necessary to install one of the slots in the gap of the Hall sensor. At this time, the contact of the movable type of the runner must fully coincide with the side contact at number 1 on the lid of the traver, the body of which must be turned into a steady position and fix with the help of a mounting nut.

Then you should tighten the fastening nut and install the lid with the candles in place.

When all the work is completed, you need to start the engine, warm it up to a temperature of + 50 ... + 60 ° C and correct the contactless ignition with a strobe.

The stroboscope needs to be connected to a traver. It will provide simultaneous outbreaks to form a spark in cylinders. Directing the lamp on the pulley, you can clearly see the position of the pulley tag and its change with increasing the number of engine speed.

When the piston of the first cylindrical mechanism is in the position of the highest dead point, it is recommended to combine the crankshaft pulley notch with the first long risk. This risk is located on the lid of the node of the gas distribution mechanism. This will help ensure the desired fuel fluid injection advance angle at a second risk of 5 °.

Electronic

In the electronic ignition system there is no mechanical movement of elements. The operation of this system is provided by special sensors and control unit. This makes it possible to increase the indicators of the power unit of transport and reduce the average fuel fluid consumption.

In order to establish the ignition of the electronic type, it is necessary to translate into the position of the highest dead point 4 of the cylinder of the engine part. To do this, you will need to be checked by the crankshaft ratchet until the stamp marks match.

After that, it is necessary to dismantle the rubber, spark plugs and the coil, put a new wiring and install a high-voltage coil. Then you can attach the switch to the shield motor compartment And screw new spark plugs.

High voltage wires must be connected in accordance with the procedure for the operation of cylindrical mechanisms (1-3-4-2).

A brown wire must be connected to the connector under number 1. To the connector at number 2 - black. The connector under number 3 connects the wire white color, and to number 4 - blue.

In order to correctly set the ignition, it is necessary to prepare a test lamp, a wrench to 13 and a special key for the crankshaft. Before you start working, you must turn off the engine and give it to cool. After that, it is necessary to turn off the minus terminal of the motor.

Then you need to set the first cylinder to the ignition position. Align the label on the pulley with a label on the drive of the gas distribution mechanism.

The contact system of the UAZ car with conventional electrical equipment could include the ignition distributor P119-B, the ignition coil B115-B, the ignition candles A11-U and the ignition switch of the VK330.

Contact ignition system UAZ with electrical equipment could include a ignition distributor P132 or P103, an ignition coil B5-A or B102-B, Ignition candles CH302-B or CH433, the ignition switch of the VK330 and an additional CE40-A resistor.

Contact ignition system UAZ, composition and general device.

Schematic diagram of the oscillation system of UAZ.

Ignition distributor P119-b.

The contact ignition system includes a ignition distributor that serves to interrupt the current in the primary ignition coil circuit, the high voltage distribution over the ignition candles and changes in the ignition advance angle depending on the rotational speed of the crankshaft and the engine load. It consists of a breaker, distributor, centrifugal and vacuum regulators of the ignition advance, capacitor and an octane of the corrector.

The interrupter includes a housing drive a roller with a four-rod cam and a movable plate with contacts installed on it. Fixed, connected with a mass, and movable in the form of a hammer, isolated from mass and connected by a conductor with an isolated low voltage output, as well as felt insert for lubrication cam.

The movable plate is connected by a vacuum controller designed to change the ignition advance angle depending on the engine load. The adjustment of the gap between the contacts is carried out by moving the stationary contact of the interrupter using a screwdriver installed in the slot of the adjusting screw.

The distributor includes a rotor with a toxoise plate and a lid with side and central electrodes. The central electrode contains a contact corner. The rotor rotates with the camshaft cam. The central electrode is connected by high-voltage wire with the ignition coil. Side electrodes are connected by high-voltage wires from the ignition in accordance with the order of the engine cylinders.

The high voltage current from the ignition coil enters through the contact corner to the rotor-wide plate, and from it through the side electrodes along the high voltage wires on the spark plug. Using an octane-corrector installed on the interrupter housing, a manual adjustment of the ignition advance angle is performed.

R132 ignition distributor.

It has the same design with a distributor of P119-B and differs from it the presence of a protective screen and the characteristic of the centrifugal regulator.

Centrifugal, vacuum regulators and octane corrector.

Serve to adjust the ignition advance angle. The ignition timing is called the ignition of the working mixture until the opening point of the top point of the NMT in the compression tact. Since the combustion time of the working mixture is almost unchanged, then with an increase in the rotation frequency of the crankshaft, the piston during the combustion of the mixture has time after passing the NMT, to move away from VTM to a large amount than at a low rotation frequency of the crankshaft.

The mixture will be burned in a larger volume, gases pressure on the piston will decrease, the engine will not develop full power. Therefore, with an increase in the rotation frequency of the crankshaft, the working mixture must be ignited earlier, before the piston approach to the VTC, in order to ensure complete combustion of the mixture to the moment of transition of the NMT piston with the smallest volume. In addition, with the same crankshaft rotation frequency, the ignition timing should decrease with the opening throttle valves and increase when closing them.

This is explained by the fact that when opening throttle flaps, the amount of a mixture coming into the cylinders increases, and at the same time the number of residual gases is reduced, as a result of which the combustion rate of the mixture increases. Conversely - when closing throttle valves, the combustion rate of the mixture decreases.

The ignition timing automatically varies depending on the rotation frequency of the crankshaft using the centrifugal controller. It consists of two weights that wear on the axis, reinforced on the roller plate, and are tightened with two springs. If the frequency of rotation of the loading of the loader under the action of centrifugal force is diverted to the side and turn the bar with a cam in the direction of its rotation to some angle than and the earlier opening of the interrupter's contacts is ensured, that is, a greater ignition lead.

Automatic adjustment of the ignition advance depending on the degree of opening of throttle dampers is carried out using a vacuum regulator. The diaphragm of the regulator is pressed toward the corrupter of the spring. The cavity on one side of the diaphragm is communicated with the atmosphere, and on the other with the help of the fitting and the pipeline - with a carburetor.

When closing throttle flaps, the vacuum controller is increasing. The diaphragm overcoming the resistance of the spring is bent outward and turns through the thrust turns the movable plate in the direction of increasing the ignition advance. When opening the dampers, the diaphragm is strung up to the other side, turning the plate in the direction of decreasing the ignition advance.

For manual adjustment of the ignition advance, the octane corrector is used depending on the octane number of fuel. The ignition advance angle is changed when the distributor body is rotated relative to the distributor roller with nuts. On the fixed plate of the Octane-corrector, there are divisions with the designations +10, -10. When moving the movable plate, together with the casing of the distributor in the direction of "plus", is installed earlier ignition. When moving toward "minus" - later.

Ignition coils B115-B and B5-A.

The Contact UAZ Ignition System can be equipped with one of these coils. They have the same design and differ from each other in the absence of a B5-A coil of an additional resistor placed on the B115-B coil housing. In addition, the B5-A coil has a screen. The ignition coil consists of a core with an insulating sleeve on it, on which the secondary winding, porcelain insulator, covers with conclusions and the case with a magnetic conduit is wound on top of it. The inner cavity of the coil is filled with transformer oil, which improves the insulation of the motor, and reduces the heating of the coil.

Ignition Candle A11U.

It consists of a steel case, a ceramic insulator, inside which is located a central electrode, an encloser and a side electrode. In the tip of the high-voltage wire connected to the candle, a resistor is set to suppressing radiocomme.

Shielded Ignition Candle CH302-b.

The SHA302-B shielded spark plug kit includes rubber bushingSealing the input of the wire in the candle, a ceramic insulating screen sleeve and a ceramic liner with a built-in resistor to suppress radiocomme. The connection of the high-voltage wire with an epecatrode of the liner is as follows.

At the end of the high voltage wire leaving the shielding braid, the rubber sealing sleeve of the candle is put on, and then the wire is entered into the contact device. The wires of the wires, bare along a length of 8 mm, is inserted into the hole of the sleeve, struck in the bottom of the ceramic cup of the contact device, and flies so that the contact device is clamped on the wire.
