Contact ignition system UAZ, composition and general device, contact ignition contact system. Procedure for installing ignition by car UAZ Electronic ignition circuit on UAZ

Step 1. Preparation

General view of ATE2 set:

It is still necessary, in addition to the system itself, a set of a chauffery tool. At a minimum, you need: horn keys on 8, 10, cross screwdriver and "curve" starter (if a body elevator is made or not the ability to use the "curve" starter - you need something that you can turn the engine).

Step 2. Dismantling of the native distributor sensor (hereinafter - the traver) and the ignition coil

Before removing the native rubber, you must turn the engine to combine the tag on the "5o to NTC of the 1st Cylinder" with the pin on the block. Rotate the engine clockwise, we combine the labels and then remove the lid of the traver. If the slider is directed towards the cylinder block, then you can dismantle the native rubber. If not, the slider is directed to the opposite side of the block, you need to turn the engine for another turn. Now the slider looks at the engine.

To dismantle the rubber, remove the high-voltage wires and the hose of the vacuum controller and the key to 10 turn the fastening bolt of the octane-corrector plate to the drive housing and, shaking the rubber, take it out. In the event that there are not enough forms of hands, we get a slotted screwdriver from the bottom of the octane-corrector plate, and, leaning on the drive, shifting the rubber upward.

Then remove the regular ignition coil. We unscrew 2 nuts and remove the wires from the conclusions. The coil itself is screwed with 2 screws to the engine shield.

Step 3. Installing a new trambling and ignition coil.

Before installing a new rubber, you need to mount the octane-corrector plate on it. This plate has no fixed position on the housing of the traver. The location of the primary installation is a little left of the housing of the vacuum regulator, if you look at the rubber on top. Putting the plate on the housing, and putting it up with an approximate location, 10 tighten the nut on it. Thus, the plate crimps the housing as a clamp.

ATTENTION (!) - Do not make an excessive effort, this material is very fragile!

Finally, the position of the plate is selected already during the exhibition of the engine on the engine.

Now the rubber is ready to install on the engine. Whatever the rubber rose into the drive, it is necessary to achieve the coincidence of the protrusions on the coupling from the bottom of the traver with the slots on the drive roller. Position the rubber next to the drive and turning the coupling with a hand, achieve an exemplary protrusion with a slot on the roller.

ATTENTION (!) - The protrusions on the coupling coincide with the slot only in the same position, because The protrusions are shifted from the center line.

We insert the rubber into the drive and, turning it out of the side, to the side of the coincidence of the coupling with the drive roller. On the installed rubber, there should be no gap between the octane-corrector plate and the drive hull itself.

Remove the lid of the new traver. To do this, unscrew the crossed screwdriver 2 screws. The slider should look at the motor shield.

The fact is that at the ATE-2 traver, the numbering of the 1st cylinder does not coincide with the numbering of the standard traver. The conclusion of the 1st cylinder at the new traver is above the roof of the Hall sensor (on the cover there is a number "1" - this means a 1st cylinder). This is explained by the fact that the coupling of the ATE-2 traver is deployed to 180 °.

Then, turning the housing of the traver, we seek that the 1st cylinder connector on the lid coincided with the Runner's contact. In other words, the moment is igniting the mixture in the first cylinder. It will be the initial Woz. Naturally, it is impossible to ride it, but it is already possible to start the engine for adjustment. From the hands we wrap the fastening bolt of the octane-corrector plate to the drive housing.

Now install a new ignition coil. Put on a regular place without alterations.

Step 4. Connecting wiring and installing a switch

There is nothing complicated. If a set from the VAZ-21074 is used, then no blocks will be 3 contacts. Because In different schemes, these wires different color, I will write their number. I think from left to right through the number of switch contact numbers (the location of the switch as on the 1st photo).

The wire from contact number 3 (colors is more often blue or blue with a red stripe) connects to the plus connector of the ignition coil. On the coil, this jack is more often indicated by the "+" or "b" sign, or "wat". To the same connector you need to connect the "+" from the regular coil.

Wire from contact number 5 (more often brown or black, this is the shortest "tail") connects to any "mass"

The wire from the last contact number 6 (more often brown with red or brown with blue) connects to the second connector on the ignition coil. It can be indicated as "K", "VK" or "RUP". On the same coil connector, the wire is connected from the EPHH control unit (if any).

2 The connecting pads are connected to the switch and the output of the Hall sensor on the rubble.

Insert the wires to the rubber. Connection order 1-2-4-3, ranging from the output of the 1st cylinder. It should work like this:

It remains to find the place to the switch, because the length of the wires does not allow it to put it on a regular place. If the machine does not participate in competitions, you can put the switch next to the fuse block. Quite a reliable and affordable place. I put the wires and secured the switch under dashboard In the legs of the front passenger.

It is also worth noting that not all digital tachometers that worked with a regular transistor-switter scheme can work with the hall sensor.

It remains only to adjust the uz and tighten the fastening bolt of the octane-corrector plate.

Any car is possible due to the ignition of the combustible mixture in the cylinders power aggregate. To ensure the normal efficiency of the motor, the correct setting (SZ) is required. In addition, all the elements, including the coil, the car of the UAZ car and other components should always be in working condition.

Description SZ on UAZ

How is the installation, adjustment and adjustment of the ignition circuit on AUZ 417 or any other? We will tell about this below. But for starters, let's figure it out in principle the work of the node, as well as the varieties of SZ.

Principle of operation of SZ.

SCH Scheme and the designation of its elements for old UAZ engines

As already said, ignition on UAZ performs one of the main functions when the power unit is launched. Thanks to this system, the procedure for igniting the fuel-air mixture in the cylinders of the power unit by filing a spark is carried out. The spark is directly filed on, each of the cylinders is installed on the same candle. All of these NWs function in order mode, flamming a combustible mixture at the required period of time. It is also necessary to take into account that the ignition system on vehicles provides not only to supply the spark, but also determines its strength.

The battery of the transport is not able to generate the voltage and the current necessary for the ignition of the mixture, since this device produces a current of only a certain force. Opens the ignition system, the purpose of which is to increase the power of the machine battery. As a result of the use of SZ AKB allows you to transfer sufficient voltage to the candle to ignite the mixture.

Types of ignition systems

Contactless scheme SZ with switcher for UAZ

Today, three main types of ignition systems are distinguished, which can be installed on a car:

1. Contact SZ. It is considered morally obsolete, but continues to be successfully used on vehicles domestic production. The principle of operation is that the system issues the necessary impulse, which appears due to the operation of the distribution component. The device itself is simple, and this is a plus, because in case of breakdown, the driver will always be able to diagnose and repair independently. The cost of replaceable components is not high. The main components of the contact type system are the battery, shortcut, drive, candles, capacitor, as well as a breaker with a distributor.
2. A system called transistor. This type is equipped with many transports. If compared with the above view, the system is characterized by a number of advantages. First, the spark produced has a greater power due to increased level Voltages in the secondary winding of the ignition coil. Secondly, the contactless system is equipped with an electromagnetic device, allowing to provide stable work, as well as the transfer of energy to all nodes. As a result, when proper setting DVS, this allows not only to increase the capacity of work, but also save fuel. Thirdly, this is convenience in terms of service node. To ensure performance for a long time, after setting up and installing a traver drive, this element needs to be lubricated from time to time. To ensure normal performance, the element is lubricated every ten thousand mileage kilometers. As for the shortcomings, this is the complexity of the repair. Repair the device itself is unreal, this requires a special diagnostic equipmentwhich is only a hundred.
3. Another option SZ - electronic, Which today is most technological and expensive, so new transports are equipped with them. Unlike the two systems described above, the system electronic ignition It is characterized by a complex device that ensures the performance of not only the moment, but also other parameters. Currently electronic systems Tool all modern cars. Key advantage It is a more simplified procedure for adjusting the ahead of ahead, as well as the absence of the need to periodically check the contacts for oxidation. In practice, the fuel-air mixture in the electronic ZZ engines is almost always burning in full.
   This type also has its own minuses, in particular, on the issue of repair. It is unrealistic to produce it with your own hands, since equipment needs for this. detailed instructions On the adjustment of the ignition using the light bulb is presented in the video below.

How to put it?

How after connection, the ignition installation is made for proper operation of the motor?

What is the order of how to properly set the node setting, read below:

1. To begin with, transport must be fixed on the spot, turn on hand brake. The piston of the first cylinder must be set to the upper dead point, consider the hole on the pulley crankshaft Must match the label, which is located on the distribution gear cap.
2. From the switchgear you need to dismantle the lid. Having done this, you will see the slider that is against input 1, inside the lid. If it is not, then the crankshaft must be rotated 180 degrees and put the octane-corrector for 0. Using a wrench, tighten the pointer to the dispenser's controller housing so that it is combined with the average label at the octane corrector. Screw fixation plastic to the camshaft housing a little release.
3. Carefully turn the housing, holding the runner with your finger so that it does not rotate. So can eliminate the gaps in the drive. The body turns to the moment until the sharp part of the petal on the stator is aligned with the red risk on the rotor. Plate Fix the screw to the controller body.
4. The next step is to install the controller cover in place and diagnostics. They must be installed in accordance with the procedure for the functioning of cylinders, that is, the first, second, fourth, third. When the moment of ignition is installed, it is necessary to diagnose the correctness during the ride.
5. Run the power unit and warm it about ten minutes until the temperature is about 80 degrees. Moving on a flat and straight road with a speed of about 40 km / h, sharply press the gas pedal. If with a speed set of up to 60 km / hour you will feel or hear detonation, it should be short-lived, then everything is done correctly. If the detonation is very strong, the distribution controller must be rotated on half or one division counterclockwise. With the absence of detonation, the established advance angle must be increased, that is, the controller should be rotated clockwise.

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.

• Contactless ignition adjustment scheme

Adjusting the contactless ignition system on UAZ vehicles should be carried out with high accuracy. Allowed errors when installing ignitions lead to an increase in fuel consumption and reduce engine power.

Instruction

Install the car on a flat horizontal platform and barrix the parking brake. The piston of the first cylinder, set the upper point position. At the same time, the holes m3 should be combined (5 degrees to the NTT) on the crankshaft pulley and the pin on the cover of the camshaft gear.

Remove the plastic cover from the dispenser sensor housing. Make sure the runner electrode stood strictly opposite the output on the lid. This output is marked with a number 1 and is intended for the wire of the candle of the first cylinder.

Bolt with the pointer inserted into it, attract the dispenser's octane corrector plate to the drive housing. In this case, the pointer must coincide with the central division of the Octane-corrector scale.

Loosen the fastening bolt of the octane-corrector plate to the distributor sensor. Holding the slider to eliminate the gaps in the drive, gently turn the housing until the red line of the label on the rotor and the tip of the petal on the stator is not monitored in one line. Tighten the fastening bolt of the octane-corrector plate on the distributor sensor.

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 terminal rechargeable battery. 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 the 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, he 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, heat it up to the temperature + 50 ... + 60 ° C and adjust contactless ignition With the help of 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 UAZ-469B car ignition system included: ignition coil, ignition interrupter, ignition candles, wire and ignition switch. The primary chain of the ignition system is powered by a battery or generator.

The ignition system of the UAZ-469B, device device and the principle of operation.

Scheme of the ignition system UAZ-469B.

Is a transformer transforming low voltage The primary chain into high voltage of the secondary chain. When the engine is running, the current in the primary winding of the coil passes through the addition resistor located in the insulator between the paws of the coil fastening brackets. When starting the engine starter, this resistor is automatically turned off and the current into the primary winding comes, bypassing it, which is achieved by the amplification of the spark and facilitating the engine start.

It has centrifugal and vacuum regulators that automatically change the ignition advance angle, and 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 rotation frequency of the crankshaft or the distributor roller.

Characteristics of the centrifugal regulator.

Distributor roller rotation frequency, rpm / mining angle of the interrupter cam, hail: 200/0-3, 500/3-6, 1000/8-11, 1900-2200/17,5-20.

The vacuum controller changes the ignition angle depending on the engine load, discharge in the mixing chamber.

Characteristics of the vacuum regulator.

Deflection in the mixing chamber of the carburetor, mm RT. Art. / Ignition advance angle, hail: 60/0, 100/0-2.5, 200/5.5-8.5, 280/10-13.

The octane corrector serves to change the ignition advance angle depending on the octane number of gasoline used. Using an octane-corrector, you can change the ignition advance angle within + -10 degrees at the corner of the crankshaft rotation.

The ignition switch and starter type VK330.

It is used to turn current on and off in the primary ignition circuit and to turn on the starter. At the plastic insulator of the switch, AM (ammeter) clamps are placed, KZ (ignition coil), st (starter), etc. (receiver). Clamp AM is under constant voltage.
