Contact ignition system UAZ, composition and general device.
Schematic scheme contact system Ignition UAZ.
Ignition distributor P119-b.
Contact ignition system includes a ignition distributor which serves to interrupt the current in the primary chain of the ignition coil, the high voltage distribution over the ignition candles and the change in the ignition advance angle depending on the rotation frequency crankshaft and 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. Mixed, connected with mass, and movable in the form of a hammer, isolated from mass and connected by conductor with an isolated output low voltage, 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, the pressure of the gases to 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, at the same time of the crankshaft rotation, the ignition advance should decrease with the opening of 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 depending on octane number The fuel is used octane-corrector. 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.
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 the possibility of contactless ignition, of course, far. Therefore, many owners of UAZ seeking to improve work power aggregate, reconfigure it. 
And not only uzov, but also domestic carsFor example, alterations are subjected to both 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:
- The engine begins to work steadily in all modes;
- Improving the start "on the cold";
- Normalizes fuel consumption;
- 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:
- Hall Sensor;
- High-voltage wires (better silicone);
- 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:
- Two switches;
- Two hall sensors;
- 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:
- Machine the crankshaft until the piston does not reach the NMT in the first cylinder;
- Turn the trimmer body until the contact plate is in the slot of the sensor;
- Carefully tighten all the fastening screws to eliminate the backlash.
- 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 road common use And on off-road!
Any ignition system is non-contact mainly differs only by the manufacturer and has the following constructive features - This is a sensor-distributor or simply rubber, candles and a ignition coil, a resistor (responsible for resistance), an emergency vibrator and switch.
The rubber has a simple device consisting of a housing, covers (usually plastic), 2 regulators, roller and voltage sensor, as well as a corrector. The voltage sensor has a rotor and stator. They have special labels to set the initial ignition (primary).
The ignition coil has a primary winding resistance of 0.43 Ohm and the secondary 13000-13400 ohms, at a temperature of about 25. The maximum voltage up to 30000 V on the secondary winding.
The transistor switch is the simplest device consisting of a housing with a board, and the emergency vibrator has the same parts as the last, but it comes into operation when the switch fails.
Under what conditions do it
As a rule, the ignition needs maintenance as a malfunction is detected, but according to the regulations, it is recommended for running. 8000 km. Tighten the wiring nuts and fastening the wires of the wires. 16000 km. Inspection of the state visually, cleaning visible elements from contamination. Rotor sleeve lubrication. 50,000 km. Bearing Cleaning and Bookmark new lubricant, Cleaning all the parts from dirt, standing wiring contacts.
How to set the desired ignition point.
1. The piston of the 1st cylinder must necessarily be in the upper dead point, it is achieved by scrolling camshaft, while the labels are followed, they must coincide.
2. Remove the plastic lid from the springboard and make sure the electrode coincides the slider with a notch on the lid. 3. The corrector plate is delayed with a bolt to the housing, the tightening is performed until the pointer will be in the middle of the marked scale. 4. The plate is weakened, with the help of its holding bolt. 5. Turning the trimmer body, and at the same time holding the slider, follow the marks on the rotor and the stator (they must match), after which the plate is again delayed. 6. Collect everything in reverse order and check the car to accuracy the moment of ignition.
The engine is warmed up operating temperature (80-90 degrees), then choosing a smooth and direct portion of the road, a sharp press on the gas pedal, overclocking the car. Hearing a minor detonation, we conclude that the adjustment is made correctly. With a significantly greater detonation or it is not at all, the following manipulations produce - turns the body clockwise in the absence and against, with a significant detonation.
Lid. The slider must be placed against the input "1" inside it. If not, check the crankshaft for 180 degrees. Install the octan-on "0". Tighten the pointer to the ignition sensor housing so that it coincides with the average risk of Octane-corrector. Lightly release the plate attachment bolt to the dispenser's sensor housing.
Turn the housing carefully, holding the runner with your finger against its rotation, to eliminate the gaps in the drive, until the skin is aligned on the stator and red label on the rotor in one line. Fix the octane-corrector plate with a bolt to the dispenser's sensor housing.
Put the sensor sensor cover to the location. Check the installation of the ignition reasons according to the order of the operation of the cylinders 1-2-4-3, counting against the clockwise. After setting the moment of ignition, check the correctness of it in motion.
Get the engine, warm up to operating temperature (80 degrees). On the direct portion of the road, moving at a speed of 40 km / h, sharply press the accelerator. If a short-term detonation will be felt at 55-60 km / h, then the moment on the contactless ignition is set correctly. In the case of a strong detonation, the distributor sensor should be rotated for 0.5-1 division on the Octane-corrector scale counterclockwise. If detonation is completely absent, then increase the advance angle, turning the sensor-distributor clockwise. The division of the scale corresponds to the corner of 4 degrees on the crankshaft of the engine.

Sensor distributor
The distributor sensor has a housing, a cover, roller, a sinusoidal voltage sensor, centrifugal and vacuum regulators, as well as an octane corrector. The centrifugal controller automatically changes the ignition advance angle depending on the rotational speed.
The voltage sensor consists of a rotor and a stator. The rotor is a ring permanent magnet With tightly pressed to it from above and below four-pole rockets, rigidly fixed on the sleeve. In the top of the rotor on the sleeve installed the slider.
The sensor stator is a winding concluded in four-pole plates. The stator has an isolated stranded output attached to the output of the sensor. The second output of the winding is electrically connected to the case in the collected distributor.
A label is applied on the rotor, on the stator arrow, which serve to set the initial moment of sparking.
Resistance of windings at a temperature (25 ± 10) ° C, Ohm:
primary ..... 0,43.
secondary ..... 13 000-13 400
Developed secondary voltage maximum, in ..... 30 000
The coil has a high voltage output and two low voltage outputs:
- output to - for a compound with an output to additional resistance;
- Non-marked withdrawal - with the conclusion of the switch of the switch.
The value of the active resistance between the conclusions of "+" and "C" (0.71 ± 0.05), between the conclusions "C" and "K" - (0.52 ± 0.05) Ohm.
Consists of a housing and boards with radio elements. Switch conclusions are intended:
- output D - for connecting to low-voltage output of the sensor-distributor;
- the conclusion of the KZ - to connect to the output of the ignition coil;
- The output "+" - to connect with the output "+" of the addition resistance or fuse block.
It consists of a housing and boards on which all vibrator nodes are mounted. It has one conclusion. Including it in operation is allowed only if the transistor switch or the coil of the sensor stator is fail.
Maintenance
After 8,000 km
Check the liner of the low-voltage distributor sensor connector, fastening the connecting wires.
After 16,000 km
Check the ignition distributor: inspect the slider, the distributor cover and, in the case of their contamination, wipe the X / B with a cloth moistened in pure gasoline.
Lubricate from the dropper (4-5 drops) the rotor sleeve (you first remove the slider and the filter under it).
After 50,000 km
Thoroughly rinse the pure gasoline ball bearings of the stator's support, label lithol-24 lubrication into it no more than 2/3 of the free volume of the bearing (you first remove the lid, the slider, the rotor and the stator support).
Ignition Moment Setup
1. Install the piston of the first cylinder in the upper dead point of the compression tact in the first cylinder to the coincidence of the M3 hole (5 ° to the NTT) on the crankshaft pulley with the pin on the camshaft cap.
2. Remove the plastic lid from the distributor sensor. Ensure that the electrode runner was installed against the output on the sensor-sensor cap marked with a digit "1" (output for the ignition wire of the cylinder of the first cylinder engine).
3. Tighten the coarse-corrector plate inserted into it inserted into it to the drive enclosure so that the pointer coincides with the average division of the Octane Corrector.
4. Loosen the fastening bolt of the Octane-corrector plate to the dispenser's sensor housing.
5. Holding the runner against its rotation with the finger (to eliminate the gaps in the drive), carefully turn the housing to align in one line of the red mark on the rotor and the island of the petal on the stator. Fasten the octane-corrector plate with a bolt on the dispenser's sensor housing.
6. Install the distributor sensor cover, check the installation of the ignition wires to the candles in accordance with the order of engine cylinders 1-2-4-3, counting counterclockwise.
After each ignition installation, check the accuracy of installing the ignition torque, listening to the engine operation when the car is moving.
To do this, warm the engine to a temperature of 80 ° C and, moving in direct transmission by roven road at a speed of 40 km / h, give a car overclocking, dramatically clicking on the drive pedal throttle valve. If there will be a slight short-term detonation to a speed of 55-60 km / h, then setting the moment of ignition is made correctly.
With a strong detonation, turn the valve sensor housing () on the octane-corrector scale by 0.5-1.0 division counterclockwise. Each division of the scale corresponds to a change in the moment of ignition by 4 °, counting on the crankshaft. With the complete absence of detonation, it is necessary to increase the ignition advance angle by turning the sensor housing of the distributor clockwise.
