A properly functioning ignition system is the key to reliable engine operation and easy starting. In addition, fuel consumption and dynamic characteristics also depend on the moment of ignition. The wrong moment can cause engine detonation, which can lead to very disastrous consequences. Let's see how to install the ignition on the VAZ-2106, and also talk about electronic ignition and installing the ignition switch on this model from AvtoVAZ.

Contactless ignition on the VAZ-2106

Regularly, a contact-type ignition system was installed on this model. Many have had a lot of problems with it. For this reason, most motorists change contact ignition to a contactless or electronic system. This was put on the VAZ-08 model and beyond. The contactless system includes the following elements. This is an ignition coil, a distributor or distributor with a hall sensor, a switch and wiring.

The accessories can be purchased separately or as a set. There are usually no problems with buying kits. But if the components are purchased separately, then you should pay attention to the length of the shaft in the distributor. The thing is that the engine in this model can be of different modifications. It is better to look at the markings on the engine in advance. If the marking is 2103 or 2106, then the distributor must be with a longer shaft. Before installing contactless ignition on the VAZ-2106, you need to make sure that the distributor is suitable, since it is not cheap.

Unlike motors marked 2101 and 21011, 2106 has a different piston stroke. Sometimes, in special cases, instead of a standard crankshaft, a crankshaft from Niva models is installed. This way you can increase the piston stroke. This tuning will not affect the length of the distributor shaft, which is selected according to the marking on the engine block.

Choosing and buying a kit

Experts advise to purchase domestic kits made in Stary Oskol. More than once these sets confirm their high quality. They are more reliable than all other analogues. As for the Hall sensor, it is not recommended to purchase Kaluga-made Avtoelectronics products in the future.

Instructions for installing the ignition

Let's see how to install electronic ignition on the VAZ-2106. In fact, the installation process is simple, but requires a certain amount of time and attention.

The crankshaft is turned with a key or any convenient device until the mark on the pulley aligns with the risk on the engine block. When the marks are aligned, the first or fourth cylinder of the engine will be at top dead center. This is checked by unscrewing the spark plugs and removing the cover from the ignition distributor. The slider inside the distributor will be turned to the first or fourth cylinder. The easiest way to navigate is by the lid.

Then the vacuum tube is removed from the fitting on the UOZ vacuum regulator, the wires are pulled out of the distributor cap and the nut holding the distributor is unscrewed. Then the distributor is removed, but first you need to remember or sketch how the slider stands. In the process of removing the distributor, it is important to ensure that the gasket that is installed between the block and the distributor has not gone anywhere - it will still be needed.

Next, they take a new distributor from the contactless ignition kit and put a gasket on it. Then the shaft is turned so that the slider is set in the same position as on the old distributor. Then you need to install the distributor on the block and tighten the fixing nut a little. After that, they put on the cover of the distributor, the wires are connected to the candles. Do not forget about the vacuum tube.

Next, the ignition coil is dismantled, and a new one from the kit is installed in its place. The main thing here is not to confuse the wires that were connected to this very coil. Sometimes you can connect the wrong wire to the positive contact. Then install the switch. In more recent cars of recent years, there is a special place for it near the distributor. On older models, you will have to make holes to mount the switch.

When you know how to install the VAZ-2106 electronic ignition yourself, all that remains is to learn how to regulate the UOZ.

UOZ setting

Electronic ignition is installed and now let's see how the ignition timing is adjusted. This operation can be performed in three different ways - with a stroboscope, with a light bulb, and also with a spark.

We use a stroboscope

Let's see how to install the ignition on the VAZ-2106. By the way, this method is the fastest, but there are nuances. Any stroboscope for ignition is suitable for work - you can buy a device in a store or make it yourself. It is best if the power supply of the device is taken from the vehicle's on-board network, and the signal is connected in the form of a sensor that is put on the BB wire of the first cylinder.

When everything is prepared, remove the tube from the vacuum regulator, start and warm up the engine. The motor should run normally at idle. Then loosen the bolt or nut that secures the ignition distributor housing. The stroboscope is directed to the crankshaft, or rather to its pulley. The setting itself is that the mark on the pulley is in a special way to the marks on the timing cover. By rotating the distributor, you can make the label move. When the position is found, the distributor can be tightened.

In general, this is practically the only accurate way to set the ECU on engines with a non-contact ignition system. It is described in detail in books, where it is also written how to properly install the ignition on the VAZ-2106. The ignition is set up in the same way.

OOP by ear

How to install the ignition on the VAZ-2106 with your own hands? Sometimes it may happen that the advance angle recommended by the factory is not enough for normal engine operation. Then the stroboscope should be thrown into the trash - there will be no sense from it. The engine has a certain mileage, wear and factory parameters are no longer suitable for it. Then you should tune using your ear. Let's see how to set the ignition on the VAZ-2106 using only the ears.

The engine is idling, and by rotating the distributor, an increase in speed is achieved. If you increase the angle, the speed will increase, and the engine will stabilize. From this position, you need to slightly turn the distributor in the direction of decreasing the angle - just a little. Then the distributor is tightened.

About installing the ignition switch

The ignition switch is also part of the design of the engine's ignition system. Sometimes the contact group or the mechanical part wears out in it. It will not be superfluous to consider how to install the ignition switch on the VAZ-2106.

Before installing the element, it must be removed. To do this, disconnect the negative terminal from the battery, then remove the decorative trim on the steering column. Then it is important to sketch or write down where the wires are connected. After that, using a Phillips screwdriver, unscrew the lower fasteners of the ignition switch. Next, insert the key into the lock and turn it to the zero position to disable the steering lock mechanism. With a thin awl, press the latch, due to which the lock can be held in place. If you pull the key, the lock can be removed.

After the lock mechanism is removed, a new lock is installed in the same way in reverse order.

Connection

The ignition is switched on by means of an electrical circuit connection. For this, the ignition lock has wires with connectors. On a new lock, more often the wires will be connected using a large round connector.

The blue wire with a black stripe is connected to terminal 15 and is responsible for the ignition, stove and other devices. A pink wire is connected to pin 30, a brown wire is connected to pin 30/1, a black wire is connected to INT.

Conclusion

We examined how to install the ignition on a VAZ-2106 carburetor. After installing electronic ignition, this system will no longer cause problems for the owner. The car will work properly and start under any conditions, in any weather.

On the VAZ 2106 car models, the ignition system remained unchanged until 1980. Then, in the design of the VAZ 21065, a non-contact-transistor ignition interrupter circuit was first implemented. However, almost on most model versions of the "six" a contact ignition system (KSZ) was installed. The electromechanical ignition system with the opening of the contacts of the distributor is considered traditional for the classic VAZ 2106. It provides for the opening of the contact group using the R-125B ignition distributor.

How the ignition system works on the VAZ 2106

The system consists of the following components:

1. ignition lock;
2. distributor;
3. coils;
4. high/low voltage wires;
5. 4 candles.

Egnition lock VK347 in position "I" connects the battery to the ignition system, in key position "II" the engine starts from the starter.

Breaker-distributor (distributor)- connects the spark plugs to the coil in the order of operation of cylinders 1-3-4-2. Creates an advanced ignition moment (in the compression stage) of the fuel mixture in the combustion chamber. Initially, the R-125B with a mechanical octane corrector was installed on the VAZ model, but it had a small adjustment range.

Since 1986, they began to install a breaker equipped with a vacuum ignition timing controller model 30.3706.

Coil is a step-up 2-winding transformer that creates high-voltage pulses with a voltage of over 10 kV. Typically, a reel B 117-A is used, equipped with an open-ended magnetic circuit.

wires carry out the transmission of high-voltage / low-voltage voltage to the actuators and candle elements of the system.

Candles A17 DV or analogues create a spark (the gap between the electrodes is 0.5–0.6 mm) from the applied pulsed voltage in the combustion chamber.

Electric current flows through the circuit of the ignition system: positive (+) of the battery → ignition switch → coil → distributor → spark plugs.

When is Ignition Adjustment Required?

The correct ignition setting of the VAZ 2106 improves the ease of starting the car engine, the dynamics and the resource of the power unit. Without fail, it is carried out after:

• overhaul of the engine or operations related to the partial disassembly of the engine;
• reinstallation of the camshaft;
• valve burnout;
• replacement of cylinder block gaskets, chain / timing belt.

What happens if there is no regulation

Contactless ignition is one of the most popular ways to tune domestic cars. Photo: vaz-remzona.ru

In the case of ignition advance, a metallic overtone will appear during engine operation, the engine is unstable, idle speed “floats”, tractive effort drops, and fuel consumption is excessive.

With late ignition, the throttle response of the motor drops, the motor is coked with soot, as a result of which it quickly heats up. To accelerate the car, you need to press the gas pedal hard.

The consequence of incorrectly set ignition is premature wear of the cylinder-piston group, engine jamming from overheating and failure of vehicle components.

How to properly adjust the ignition on your own

Ignition adjustment can be done in a repair shop using a stroboscope or independently. Of the tools and equipment, you will need a crankshaft key, a key for “13”, a 12 V control light, which can be replaced with a voltmeter. First, unfasten the latches and remove the distributor cover. At the first stage of work:

1. Disconnect (-) battery terminal.
2. On an idle power unit, set the piston of the first cylinder to the position corresponding to the compression phase (spark jump) before the top dead center.
3. To do this, turn out the candle of the first cylinder and plug the hole in the cylinder head with your finger.
4. Turning the crankshaft with a key, we select the position in which the air will push the finger out of the hole.
5. We combine two marks: on the pulley and timing cover. The latter has a long (0°), medium (5°) and short (10°) risks, indicating a different ignition timing. It is necessary to combine the risk with the average timing mark, which means setting the ignition timing to 5 °.
6. Screw back the spark plug and connect the high voltage cable.

At the second stage of work, we determine the ignition moment:

1. Connect the (-) battery terminal.
2. With a wrench, loosen the nut on the “13” fastening of the distributor.
3. We connect with the help of crocodile clips one end of the control lamp is connected to the ground, the other is connected to the low-voltage wire of the bobbin.
4. We connect the central wire of the breaker to the ground.
5. Turn the ignition key to the "I" position, the control lamp will light up.
6. Very slowly turn the distributor housing clockwise until the bulb turns off.
7. Turn the distributor slider counterclockwise until the lamp turns on.
8. Having fixed the position of the mechanism with one hand, we twist the fixing nut of the distributor with the other hand.

A quick way to tune the ignition "by ear" in emergency cases

In unforeseen circumstances, it may be necessary to adjust the ignition on the road. To do this, on a running internal combustion engine, set the suction (air damper of the carburetor) to approximately 2000 rpm. engine. Loosen the fastening of the distributor and rotate the body alternately in both directions. Listening to the sound of the engine, we select the optimal position of the distributor. The power unit must develop the maximum number of revolutions and work without "failures". In the found position, we fix the distributor.

Checking the ignition settings

Checking on the road will help identify adjustment flaws, for this you should:

• during the trip, develop the car on the road up to 40-50 km / h and, switching to the 4th speed, sharply press the gas pedal to the floor;
• there will be a ringing of "fingers" and a detonation will occur, which should occur within 2-3 seconds ;
• if the detonation lasts longer (sometimes it does not stop after some time after turning off the engine), it is necessary to delay the ignition, loosen the fastener and turn the distributor 1 ° clockwise;
• in the absence of detonation and ringing of fingers, it is necessary to make the ignition earlier, it is necessary to turn the breaker body 1 ° counterclockwise;
• after bringing the breaker body to the optimal position, tighten the fixing nut.

Conclusion

If the adjustment range is not enough to set the required parameters of the ignition system, you should pay attention to the serviceability of the system components. KSZ remains operational, but there are interruptions or does not work correctly? It is necessary to check the serviceability of the following functional elements:

• breaker contacts, which often burn or melt;
• distributor movable plate bearing;
• textolite block or bushing of the breaker lever, they wear out over time;
• bobbin windings for interturn short circuit, open circuit or flashing to ground;
• armored wires / tips of spark plugs.

Consider setting the ignition timing (ignition timing) on ​​"classic" cars VAZ 2101, 2102, 2103, 2104, 2105, 2106, 2107, 2121 with a contact ignition system and their modifications. The need to set the ignition timing may arise after removing and installing the ignition distributor (distributor), or when trying to more optimally tune the engine. An incorrectly set ignition timing threatens to cause a number of problems in the operation of the engine. Here are some of them: a drop in power and throttle response, increased fuel consumption, unstable idling, problems with starting the engine, shots and pops in the muffler, black smoke from the muffler, burning valves, etc.

Required Tools

All work on setting the ignition timing on VAZ 2101-2107 vehicles can be carried out without the use of any special devices and devices. The use of a stroboscope, a control lamp does not make much sense, since after setting the ignition timing, it will be necessary to check its correctness on a moving car. Of the tools you only need:

- Open-end or box wrench 13 mm.

- Open-end or special wrench 38 mm.

Preparatory work

- We put the car on the handbrake;

Setting the ignition timing on VAZ 2101-2107 cars

We put the ignition timing under the 92nd gasoline.

1. We combine the mark on the crankshaft pulley and the mark on the front cover of the engine (the middle of the three available there).

To do this, with a special key (or a 38 mm open-end wrench), slowly rotate the crankshaft by the ratchet until they coincide.

2. We install the distributor with latches parallel to the engine, the slider contact should look at the 4th cylinder (identify by the distributor cover).

The breaker contacts must be closed. Lightly press the distributor body with the holder.

3. Turn on the ignition and slowly turn the distributor housing until the breaker contacts open. A spark will jump between the contacts.

This will be the desired ignition moment. With a 13 mm wrench, tighten the distributor holder nut.

Check of correctness of installation of the moment of ignition

Driving a car at a speed of 45-50 km / h in 4th gear on a flat road, sharply, for a short time, press the gas pedal. At the same time, listen to the operation of the engine. A short-term detonation that occurred - 1-3 seconds (knocking of "fingers") indicates the correct setting of the ignition timing, long o too long, no detonation o. It is necessary to correct the lead angle by rotating the distributor (counterclockwise - we make the ignition earlier, clockwise - later). Then check again.

Notes and additions

- There are situations when, with a correctly set ignition timing (short detonation when driving), on VAZ 2101-2107 cars, the engine idling leaves much to be desired. In these cases, many simply turn the distributor, setting the ignition a little early to stabilize the idle. It is advisable to eliminate this malfunction by adjusting the carburetor, and not by rotating the distributor, since the previously set correct ignition timing is lost.

Adjusting the ignition of the VAZ 2106 begins with the adjustment of the angle of the closed state of the contacts. It is necessary to adjust the UZSK if you use a classic or transistor ignition system. If a thyristor system is installed, the UZSK value is not critical. To start the adjustment, remove the cover of the distributor.

Ignition adjustment on the VAZ 2106.

If a classic ignition system is installed on the car, then before starting the adjustment, it is advisable to clean the contacts of the distributor with a file. After stripping, we check the condition of the contacts - you need to make sure that the contacts are in contact with each other over the entire plane.

If necessary, the contacts will have to be adjusted. Now turn the crankshaft to such a position at which the distance between the contacts will be maximum. We turn off the screw, which fixes the contact group on the bearing plate,

now we introduce the probe - it thickness should be approximately 0.4mm between contacts,

after the position of the contact group is selected, at which the probe will move with little effort, this position must be fixed.

We check the size of the gap with two probes, a thick probe will not be able to pass into the gap between the contacts, and a thin one will move without any effort. In order to rotate the crankshaft, it is advisable to use a special key.

If this is not the case, then we put the fourth gear and gently push the car. The starter cannot be used, because it is almost impossible to get the desired angle of rotation. Gap, obtained between the contacts of the distributor, gives the necessary importance to UZSK, Do not forget that the angle is critical, not the gap! That's it because of this, you need to check the adjustment by measuring the angle, which is approximately equal to 55±3°.

The easiest option is to use an electronic tachometer, which has the function of measuring UZSK. To use this device, you need to assemble the distributor and start the engine. The tachometer must be switched to the UZSK measurement mode.

In the event that the UZSK goes beyond the limits recommended by the manufacturer, the gap adjustment will have to be repeated. There is another way, in which case you need to measure the angle. The first thing we do is pull out the central BB wire from the cover of the distributor and hook it to the mass of the car, the wire may not be pulled out, but then there will be a risk of breakdown in the coil to the wire going from the distributor to the ignition coil, you will need to connect a 12-volt light bulb.

The lamp will light up if the ignition is on, and the distributor contacts themselves are open, and go out when they are closed. If a thyristor or transistor system is installed on the car, then the lamp will not light when the contacts are open, due to the fact that there is a current limiter. Then the light bulb will have to be replaced with a voltmeter; in the position of open contacts, it shows 12 V, and on closed - 0.

Rotate the crankshaft clockwise, rotate it until until the contacts are closed. Given remember the position of the slider, it is desirable to note his distributor. The crankshaft must be rotated until the contacts open.

We remember this position of the slider, after which the angle between these two positions is measured. This is done as follows: we measure the length of the arc of a circle along the distributor body, after which we calculate the angle in degrees using the formula:

(360pd)/l in which:

• p=3.14 - Pythagorean number;
• d=70 mm - diameter of the distributor body;
• l, mm - the measured length of the arc along the distributor body between the marks.

If UZSK is set correctly, the length of the arc will be 33±2 mm.

Now let's move on to the second stage. It consists in adjusting the lead angle.

For VAZ-2103, VAZ-2106 car engines opening moment distributor-breaker, which corresponds to the spark of the 1st cylinder, ahead of the top dead center of the piston of the first cylinder by 0 ± 1 °. Described below several ways to adjust.

Strobe adjustment

We hook the stroboscope to the car network. Remove and plug the vacuum corrector hose from the distributor. Now the engine needs to be started and warmed up to a temperature at which it will steadily keep idle speed. After you need to loosen the bolt that fixes the distributor housing. The strobe light must be directed to the pulley, which is located on the crankshaft.

Now let's start turn the distributor, until, bye label, applied to the pulley, not will rise relative to the marks on the cover of the gas distribution mechanism. In this position, the distributor body is fixed.

Light bulb adjustment

This method is considered a classic, as it can be found in all automotive literature. We take a 12 V light bulb and attach two wires. When the light bulb is prepared, you can begin. The crankshaft must be rotated so that the pulley mark is located in a predetermined manner, in relation to the marks on the timing cover, the distributor slider must be opposite the BB wire of the 1st cylinder.

I repeat that if there is no special key, then turn on the fourth gear and push the car. One of the light bulb wires is connected to the wire that goes from the distributor to the ignition coil, the second wiring must be connected to the mass of the machine. The central wire is removed from the cover of the distributor, we attach it to the ground. The bolt securing the distributor must be loosened.

Now turn on the ignition. The distributor housing must be turned clockwise, it must be turned until until the light goes out. Then you need to carefully rotate in the other direction, as soon as the light turns on, we stop turning - it is in this position that you need to fix the distributor.

spark control

We put the crankshaft in the desired position, pull out the central wire from the cover of the distributor, and fasten it at a distance of about 5 mm from the mass.

We loosen the bolt that secures the distributor housing, after which the ignition is turned on. The distributor housing needs to be rotated clockwise 10-20 degrees. Then you need slowly reverse, until, until a spark strikes, after we fix the body of the distributor.

Adjustment by ear

There is another way to adjust, "by ear", but this is an inaccurate way - you will get a significant error, but you will be able to get to the settlement. Such an adjustment is made as follows: we start the engine, loosen the bolt that fixes the distributor housing. By turning the body, we find a position in which the engine speed will be maximum, now we turn it a few degrees clockwise, after which we fix the distributor.

Checking the Adjustment Results

We pass to the last stage, we need to check the results. The results are checked by the behavior of the car on the road. The engine needs to be warmed up, drive onto a flat section of the road, pick up speed of 40-50 km / h, engage fourth gear and sharply press the gas pedal. Within 1-2 seconds, characteristic knocks similar to clatter will be heard, and the car will immediately begin to pick up speed confidently.

If no sounds are heard, then you need to turn the distributor counterclockwise by one division, this procedure should be repeated until a sound is heard.

Remember that detonation should be no longer than 2 seconds. In the event that during the test you had to change the position of the distributor too much, then you have problems.

The cause of the malfunctions may still be in the deviation of the fuel composition from the nominal, as well as in the incorrect operation of the distributor systems.
