Contactless ignition VAZ 2106 connection diagram. Contactless ignition system. What is contactless and electronic ignition

How does the contactless system work? Its operation is as follows:

  • the primary winding of the ignition coil is connected to the generator and car battery through a switch, and is always under high voltage. As soon as the Hall sensor detects that the piston is approaching top dead center, it is disconnected from the battery;
  • after the breakup electrical circuit a pulse discharge occurs in the secondary winding of the coil. It is this that is transmitted to the distributor via a high-voltage wire;
  • the distributor runner transmits the impulse further to the spark plug of the cylinder whose piston was detected by the sensor;
  • a spark occurs, which leads to ignition of the air-fuel mixture;
  • Hall sensor detects the piston passing the upper dead center, and the circuit closes again. The process is cyclical and is repeated the required number of times.

How to install a contactless ignition system on a VAZ-2106

Installing an electronic ignition system is a relatively simple procedure that any experienced driver can easily handle.


It is carried out in the sequence described below:

  • set the piston of the first or fourth cylinder to top dead center;
  • remove the distributor. In this case, it is advisable to remember the position of the slider, and also replace the high-voltage wires in order to avoid problems when performing subsequent steps;
  • We install a distributor from a contactless ignition system. We connect high-voltage wires and a vacuum tube;
  • we mount a new high-voltage coil and connect the wiring to it;
  • install the switch. Usually it is placed in close proximity to the distributor in a specially designated place. We connect the connector with wires.

Today in specialized stores you can purchase a complete set without any problems. electronic ignition for installation on VAZ-2106 cars. If for some reason you are forced to purchase system parts separately, we strongly recommend that you pay Special attention choosing a distributor.

The thing is that different engines were installed on different modifications of the sixes and therefore not all ignition distributors are suitable for them. If the cylinder head of the power unit is marked 2106 and 2103, then you will need to buy a distributor with an extended shaft.

Setting up electronic ignition


How to set electronic ignition on a VAZ-2106 car? Experienced car enthusiasts will be able to do this even without a strobe, since the procedure is not particularly complicated. You will need to do the following:

  • slightly loosen the nut holding the distributor. The engine should operate in normal mode;
  • we turn the distributor in different directions, trying to achieve the most stable operation of the engine, determining it by ear;
  • Once the goal is achieved, tighten the nut until it stops.

When setting the ignition in this way, the accuracy will not be very high. Therefore, we strongly recommend that you still use a strobe.

The VAZ-2106 car is mainly equipped with a classic electrical system ignition

On modified model VAZ 21065 was equipped with contactless systems. IN classic look B117A coils are used, in a contactless system - 27 3705, the main difference of which lies in some details and winding data. The history of the production of the famous VAZ “six” VAZ 2106 dates back to 1976. From the very beginning of its production, a classic of the domestic automobile industry, equipped with an 80 hp engine. forces, has become the most popular and sought-after model among car enthusiasts.

The car is equipped with an engine start lock, typical for the entire line of VAZ cars, consisting of three main parts: a contact part, an anti-theft device and the lock itself.

When the anti-theft device of the lock is released, the device is replaced as a complete set. The contact part, secured in the ignition housing using a snap ring, can be replaced in separately. The vehicle starting device is installed under the instrument panel on the driver's left side on the steering shaft bracket.

The flawless operation of any car depends on the trouble-free and coordinated operation of all its mechanisms. Not the last place in this series is the correct installation of the ignition system. After the car leaves the assembly line, the correct clearance is set by factory specialists. During long-term use of the car, a malfunction may occur, which may lead, as one of the reasons, to excessive fuel consumption, or as one of the main reasons, the car will stop starting. In this case, it will be necessary to install the VAZ 2106 ignition according to the factory technical parameters. You can do this yourself by doing everything necessary work do it yourself, or contact a professional who is familiar with all the nuances correct installation ignition systems.

Ignition installation for VAZ-2106

Before installing the ignition system, it is necessary to check the gap of the breaker contacts, which should be within 0.35 ± 0.05 mm. If the gap size does not correspond to these parameters, then it will be necessary to install it using a twelve-sided wrench size 39mm. A control lamp helps to set the ignition correctly on the VAZ 2106.

If there is no test lamp available, then you can install it on a spark by connecting a spare spark plug, which will help prevent system failure during work. The ignition is considered to be correctly set when the spark in cylinder I or IV jumps between the first and second exhaust marks. It is worth adding that in the event of oxidation of the breaker contacts, the control lamp will light constantly, regardless of the position of the distributor body.

The most common cases of malfunction of the VAZ 2106 electronic engine start include: failure of the ball bearing 900706U in the distributors, especially recent years exhaust, which are equipped with a vacuum corrector diaphragm, breakdown of the distributor cap, slider and resistor in the slider.

The destruction of the ball bearing leads to uneven operation of the car engine at idle and it stops working at full power, while the tachometer needle can “walk” across its entire scale, regardless of engine speed. This situation can be corrected by performing a few simple steps:

  1. disconnect the vacuum hose from the distributor;
  2. Having tied a strong knot at its end, put it away so that it does not dangle;
  3. use a bar to press the vacuum corrector rod in accordance with Figure 24a; if the bar does not fit between the bend of the rod and the body, then its end is made slightly narrower, as shown in Figure 27b;
  4. re-adjust the gap in the breaker contacts, as described above;
  5. set the ignition angle to +7°30’

Now you can drive as with the ignition distributor of the first editions, but it is worth considering that in this case there will be an increase in fuel consumption by approximately a third and an increase in exhaust toxicity.

In many ways, correct work The engine starting system depends on the spark plugs installed on it. With just a visual inspection of the spark plugs, you can determine the malfunction piston group, ignition and power systems. A spark plug with an oily working surface cannot be restored.

You can try to restore the spark plug by installing it on the second or third cylinders of a well-warmed engine, or sandblasting working part. It is recommended to replace spark plugs after every 30,000 km. mileage

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

How to adjust electronic ignition on a VAZ 2106 by spark

Ignition adjustment

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

If the need arises, the contacts will have to be adjusted. Now turn the crankshaft to such a situation at which the distance between the contacts will be maximum. We unscrew the screw that secures the contact group on the bearing plate,

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

after position is selected contact group , 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 put it in fourth gear and carefully push the car. You won't be able to use a starter because it's almost impossible to get the right angle of rotation. Gap, obtained between the contacts of the distributor, gives the necessary importance to UZSK, Do not forget that It's the angle that's critical, not the gap! It is precisely because of this that you need to check the adjustment by measuring the angle, which is approximately equal to 55±3°.

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

If the UZSK goes beyond the limits recommended by the manufacturer, the gap adjustment will have to be repeated. There is another way, in which you need to measure the angle. The first thing we do is pull out the central explosive wire from the distributor cover and hook it to the ground of the car; you don’t have to pull out the wire, 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 light 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 light will not light if the contacts are open., due to the presence of a current limiter. Then the light bulb will have to be replaced with a voltmeter; in the open contact position it shows 12 V, and in the closed position - 0.

Scroll the crankshaft clockwise, you need to turn it until until the contacts close. Given remember the position of the slider, it is advisable to mark it on the distributor. The crankshaft must be rotated until the contacts open.

We remember this position of the slider, then measure the angle between these two positions. This is done like this: we measure the length of the circular arc using the distributor body, then 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 - measured length of the arc along the distributor body between the marks.

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

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

Adjusting the ignition timing

For engines of VAZ-2103, VAZ-2106 cars contact opening moment distributor-breaker, which corresponds to the spark of the 1st cylinder, advances the top dead center of the piston of the first cylinder by 0±1°. Below is described several ways of adjustment.

Adjustment with strobe light

Produced this way. We hook the strobe light to the car's network. You need to 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 stable idle speed. Then you need to loosen the bolt that secures the distributor body. The strobe light must be directed at the pulley, which is located on the crankshaft.

Now let's begin turn the distributor, until, bye mark, applied to the pulley, Not will align with the marks on the timing cover. In this position, the distributor body is fixed.

Adjustment "light"

Adjusting the ignition using a light bulb

This method is considered classic, as it can be found in all automotive literature. Take a 12 V light bulb and connect two wires. When the light bulb is prepared, you can begin. The crankshaft must be rotated so that the pulley mark is positioned in a given way, in relation to the marks on the timing cover, the distributor slider must be opposite the explosive wire of the 1st cylinder.

I repeat that if there is no special key, then engage 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 wire must be connected to the ground of the machine. The central wire is removed from the distributor cover and connected to ground. The bolt securing the distributor must be loosened.

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

Spark adjustment

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

Loosen the bolt that secures the distributor housing, then turn on the ignition. The distributor housing needs to be turned clockwise by 10-20 degrees. Then you need rotate slowly in the opposite direction, until, until a spark strikes, then secure the distributor body.

Adjustment by ear

There is also a way to adjust, “by ear”, but this is an inaccurate method - you will get a significant error, but you will be able to get to settlement. This adjustment is made as follows: start the engine, loosen the bolt securing 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, then we fix the distributor.

Checking the adjustment results

Let's move on to the last stage, we need to check the results obtained. The results are checked based on the car's behavior on the road. You need to warm up the engine, drive out onto a flat section of the road and pick up a speed of 40-50 km/h, engage fourth gear and sharply press the gas pedal. Within 1-2 seconds, characteristic knocking sounds similar to clattering will be heard, and the car will immediately begin to confidently pick up speed.

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

Remember that detonation should not last longer than 2 seconds. If during the test you had to change the position of the distributor too much, then you have problems.

The cause of the malfunction may also be a deviation of the fuel composition from the nominal one, as well as incorrect operation of the distributor systems.

Despite the fact that the “classic” VAZ 2106 has long been out of production, a considerable number of these cars are in use in Russia. Since their design is outdated, the desire of the owners of the sixth model of Zhiguli to improve it by any means is quite understandable. One of effective options- replace the standard ignition system with a non-contact one (abbreviated as BSZ), where sparking is controlled by electronics. The replacement procedure is quite simple and accessible to anyone who wants to improve the engine performance of their “six”.

What is BSZ and how does it work?

To successfully install and configure contactless ignition, it is advisable to understand the operating principle of the system, which consists of the following elements:

  1. Main ignition distributor (otherwise known as distributor). Inside it is installed a photoelectric Hall sensor, a vacuum drive for adjusting the advance angle and a so-called slider with a moving contact.
  2. A coil that produces a high voltage pulse. It has 2 windings: the primary, consisting of a small number of turns of thick wire, and the secondary, wound thin wire with a large number of turns.
  3. Electronic unit - switch equipped aluminum radiator cooling. The latter plays the role of a fastening element.
  4. Spark plugs connected by high-voltage wires to the distributor.
  5. Wires for connecting elements to each other.

For reference. In the standard outdated VAZ 2106 systems, there was a contact group inside the distributor instead of a Hall sensor, and there was no switch at all.

The first contact of the coil is connected through the ignition switch relay to the generator, and the second to the control unit. There is also a high-voltage wire going from it to the distributor. large section. There are 2 bundles of wires coming out of the distributor, connecting it to the switch and spark plugs. The system operates according to the following algorithm:

  1. After turning on the ignition by turning the key in the lock, a voltage of 12 V is applied to the primary winding of the coil, which creates an electromagnetic field.
  2. When the crankshaft rotates and one of the pistons reaches top dead center (TDC), the photoelectric sensor sends a signal to the switch, which briefly breaks the connection between the coil and the voltage source - the generator or battery.
  3. During a circuit break, a voltage pulse of 20 to 24 kV is generated in the secondary winding of the coil, transmitted through a large cross-section wire to the distributor slider.
  4. The movable contact of the slider directs the impulse to the spark plug where the piston reached TDC. A powerful spark jumps between its contacts, igniting the mixture of fuel and air in the combustion chamber.
  5. The distributor shaft is driven by a gear transmission connected to the crankshaft. When the next piston moves to TDC, the shaft rotates and the moving contact connects to another spark plug, and the Hall sensor sends the next signal and the sparking cycle is repeated.

Reference. In older systems, the circuit was broken mechanically using a cam on the distributor shaft, pressing on the contact group.

Advantages of contactless systems

For an ignorant car enthusiast, the main argument in favor of BSZ is the fact that on this moment no manufacturer produces cars with a contact-cam spark generation system. Foreign brands abandoned it in the distant 80s of the last century, and in Russian Federation mechanical ignition lasted until the 90s. The reasons for the refusal are quite clear:

  • sparks constantly flashed across the contacts, causing them to burn and require frequent cleaning;
  • the contact group wore out quite quickly, on average it was enough for 15-20 thousand kilometers, after which the element had to be replaced;
  • the wear of the bearing on which the contacts were located made itself felt, which caused unstable operation of the power unit;
  • the springs of the balance weights were stretched.

All of the listed malfunctions appeared one by one, haunting the owner of the “classic” Zhiguli. Due to an imperfect design, the spark power of the spark plugs was constantly decreasing, engine performance was deteriorating, and fuel consumption was increasing. New BSZ systems are free of such disadvantages; they are characterized by durability and stable sparking. The spark power also increased, since the output pulse voltage increased from 16-18 kV to 24 kV, which contributes to better ignition of the fuel.

Note. At first time weak point domestic contactless systems were considered to be a switch that quickly failed and could not be repaired. But later it was improved and the reliability of the BSZ increased.

Selecting an electronic ignition kit

Since the “sixes” were equipped with three types of engines (volume 1.3, 1.5 and 1.6 liters), the BSZ kits for them differ in the design of the distributor. The engine has 1.3 liters. (model VAZ 21063) there is a distributor with a shortened shaft, and in 1.5 and 1.6 liter engines. (VAZ 21061 and 2106, respectively) this shaft is equally long. The electronic ignition kit contains the following:

  • distributor with catalog number 38.3706–01 for a 1.3 liter power unit. or 38.37061 - for 1.5 and 1.6 liter engines;
  • high voltage coil marked 27.3705;
  • electronic control unit, marking - 36.3734 or 3620.3734;
  • connecting wires.

Attention! When buying a contactless kit for the “classic” Zhiguli, do not confuse it with products intended for the Niva VAZ 2121; the distributors are very similar in appearance. But the Nivov part differs in technical specifications and is marked as follows: 3810.3706, 38.3706–10 or 038.3706–10. Setting it to “six” is strictly not recommended.

Of the manufacturers selling their ignition kits on the territory of the Russian Federation, the most popular among motorists are spare parts from the SOATE company from the city. Stary Oskol. It is worth noting that the new spark plugs of the A-17DVR brand, installed on classic VAZs with electronics, are not included in the delivery package; they will have to be purchased separately. To experience the full results of the replacement, it is also recommended to install new high-voltage wires if you have not replaced them in the recent past.

Despite the fact that the oil pump is one of the most reliable components in VAZ 2106-2107 cars, sometimes it also fails. In order to replace it, it is recommended to study this material:

Preparing to replace the BSZ

The work of removing the old ignition and installing a new one does not require any special tools, fixtures or devices. An inspection ditch is not needed, and the entire operation can be carried out outdoors in good daylight. It is enough to have the following tools:

  • a 13 mm open-end wrench for unscrewing the distributor fastening nut;
  • using 10 and 8 mm wrenches, remove the coil;
  • flat and Phillips screwdriver;
  • pliers;
  • electric or hand drill with a drill to match the diameters of the switch mounting screws.

Advice. For ease of work, rent or rent from friends spanner wrench with a long handle, fits onto the ratchet nut and is used to rotate the crankshaft by hand.

To get started, perform several preliminary disassembly steps:

  1. Open the hood and disconnect the negative battery terminal.
  2. Remove the high-voltage wires from the spark plugs and distributor cap.
  3. Unscrew the spark plugs.
  4. Place a screwdriver into the spark plug hole of cylinder 1 and turn the crankshaft until the piston reaches TDC. In this case, the mark on the shaft pulley will be opposite the longest mark marked on the cylinder block.

Advice. If you do not have a wrench for the ratchet nut, the crankshaft can be turned by rotating the suspended rear wheel of the car. Don't forget to secure the car with wheel chocks, release the handbrake and engage 4th or 5th gear.

Having matched the marks and prepared new parts, you can proceed to the main stage of work.

Procedure for installing electronic ignition

The first step is to dismantle old system, performing operations in the following sequence:

  1. Disconnect the high-voltage wire coming from the coil, remove the distributor cover and note the position of the slider. For convenience, the direction can be marked with chalk on the engine valve cover.
  2. Disconnect the wires and vacuum tube coming from the carburetor from the distributor. Unscrew the fastening nut with a 13 mm wrench and remove the element from the cylinder block.
  3. Unscrew the contact nuts of the high-voltage coil and remove the wires, remembering where the wires from the ignition switch and tachometer relay were connected.
  4. Remove the coil and put it aside.

Advice. There is a gasket between the distributor and the seat of the cylinder block; do not lose it when removing the part from the car.

After disassembling, proceed to installation of the BSZ, following the following procedure:

  1. Replace the gasket from the old distributor to the new one and remove the cover from it. Having turned the slider in the desired direction, which you marked with chalk, insert the distributor shaft into the socket and secure its position with a nut. You should not tighten it too much, since you will still have to adjust the ignition and loosen the nut again.
  2. Screw in the spark plugs, having previously set the gap between the electrodes to 0.8-0.9 mm. Place the distributor cap in place and connect the high-voltage wires, observing the cylinder numbers (stamped on the top of the cover).
  3. Attach a new one in place of the old coil. If the contacts on it are located the other way around, then first loosen the fastening clamp, rotate the housing 180° and install the part on the car.
  4. Attach the commutator near the coil. After removing the washer reservoir, pre-drill 2 holes in the body side member and screw the block with self-tapping screws. Please note: the electronic element should not be lower than the tank, so that it does not flood with water in the event of a leak.
  5. Take the connecting wires and connect the electronic unit, distributor and coil according to (included with the BSZ kit). It’s not difficult to understand: the connector from the switch is connected to the distributor block, and the wires are connected to contacts “B” and “K” of the high-voltage coil. Do not forget about the wires previously connected to the old coil (including from the tachometer), they need to be connected to the new element in the same way.
  6. Place the vacuum tube coming from the carburetor onto the fitting of the distributor membrane assembly. This completes the installation of the contactless system.

Reference. In the latest VAZ 2106 models, holes are already made for mounting the switch. Look carefully at the side member on the left side (in the direction of travel of the car).

Installation instructions in photographs

The slider must be in this position before removing the distributor. The distributor cover is removed by releasing two latches. With a key number 8 and 10, you need to unscrew the wires from the distributor. The high-voltage wire is removed from the coil and the wires leading to the ignition switch and tachometer are unscrewed. Thus, the distributor is removed from the cylinder block Wires to The new coil is connected in the same way as the old one The switch is placed in a free space above the washer reservoir Do not mix up the wires when connecting the new distributor

Starting the engine and setting the ignition

If during the process of replacing the elements you did not move the marks and connected the wiring correctly, then the “six” will start immediately. Let it warm up for a minute or two, manipulating the accelerator pedal, and then proceed to adjust the ignition. This is done in two ways:

  • the most common method is “by ear”;
  • by using special device- strobe light.

Advice. If the car engine does not start and does not show signs of life when the starter rotates, then you should check that the high-voltage wires are connected correctly. Reason two: during installation, you turned the distributor cap 180°, causing the slider to transmit impulse to the 4th cylinder instead of the first and vice versa.

Adjusting the ignition “by ear” is done as follows:

  1. With the engine running, loosen the distributor mounting nut.
  2. Slowly turn it clockwise and counterclockwise, achieving the most stable operation of the power unit. The rotation angle should not exceed 15°.
  3. Having grasped the position of clear engine operation, finally tighten the distributor nut.

With the help of a stroboscope, the ignition timing is set much more accurately. If you managed to get hold of this device or borrow it somewhere, then connect it to the battery terminals and the high-voltage wire of the first cylinder. Start the engine and carefully bring the flashing lamp to the marks on the block. A stroboscope will help you see the position of the mark stamped on the pulley while the engine is running. Now you can loosen the distributor nut and turn the housing to align this mark with the last, shortest mark.

Repairing a carburetor is not difficult if you know all the intricacies of the procedure:

After adjustment, warm up the car until operating temperature and try to drive it in different modes. If you hear a knocking noise from the piston pins when you press the gas pedal sharply, then you are dealing with detonation caused by too early ignition. Loosen the distributor fastening and turn it clockwise 1-2°, no more. The knocking should disappear.

Advice. After installing the BSZ, it often happens that the engine speed at idle increases due to better spark formation. The speed is reduced to 850-900 rpm using the fuel quantity screw. In Ozone carburetors this is a screw large sizes, located on the right (in the direction of travel) at the bottom of the unit. In Solex carburetors this plastic handle, looking out from the rear and resting on the damper axis. It is not allowed to touch a “quality” screw without knowing the matter!

If you removed the distributor and high-voltage wires with the cover without aligning the marks, then the following video material will help you correctly set the ignition again:

Operating a car with an electronic system is very different from driving with an old ignition. The engine runs much smoother and more stable, and cleaning the contact group is a thing of the past. But it wouldn’t hurt the owner of a VAZ 2106 to carry a Hall sensor in reserve in case the standard one breaks down. This part cannot be repaired, although it breaks quite rarely.

Correctly set ignition is the key to proper functioning of the engine and its quick start. Also, ignition timing affects the amount of fuel consumed and dynamic characteristics vehicles, an incorrectly adjusted ignition can cause detonation, leading to serious consequences and engine damage. The question of how to set the ignition on a VAZ 2106 is decided by each car owner in his own way, some do everything “by intuition,” others use a strobe light, including those who resort to the help of auto repair shops. All this is not important, the main thing is to get the result, and how you did it is no longer so important.

Set contactless ignition assembled on semiconductor elements. In this circuit, the low voltage circuit is opened and closed by unlocking or closing the output transistor using an electronic switch.

Adjusting the ignition of the VAZ 2106 is one of the most important operations, like everything that relates to the engine in general. Electronic system ignition means that it is not the mechanics that will work in the car, but a photocell or optics. Known fact that mechanics break down and become deformed over time, but optics are more reliable in these respects. Let’s say you just need to install a contactless ignition system, set everything correctly and no longer have to think about the many difficulties associated with working with mechanical elements. For example, you no longer have to worry about adjusting the intercontact gaps and maintaining this system.

The installation of BSZ can be done by any car owner, without having any special knowledge or skills. The electronic system significantly improves engine performance, because in this case the circuit is most accurately opened and a powerful spark is created, which has a beneficial effect on starting the engine during the frost season. This ignition circuit also increases the voltage on the vehicle’s spark plugs, and the spark charge begins to produce more energy.

How to set the ignition on a VAZ 2106

Many car owners, when it comes to the engine, prefer to entrust the work to auto repair specialists. This is not bad, but every car owner can learn how to set the ignition correctly. Why do you need to do this at least a couple of times in your own car?

The timing cover has 3 marks - long, medium and short. To implement this adjustment scheme, they play important role. Long means the advance angle is 0 degrees, medium is 5 degrees, short is 10 degrees. In addition to the indicated marks, there is also TDC - the highest point of the piston stroke in its cylinder.

Disassembly of parts

To remove the distributor cap, simply unfasten the latches. The distributor is installed by securing it with a suitable nut. It is not recommended to tighten it all the way; it will come in handy later.

The main stages of adjusting the ignition system

The first stage involves adjusting the angle of the closed state of the contacts.
The second stage consists of adjusting the timing of the ignition system.
The third stage is to check the correctness of the connection diagram of the elements while the vehicle is moving. In this case, you need to focus on the diagram included in the BSZ delivery kit or the service book for the vehicle.

How is control carried out?

Start the car moving, accelerate to 45 km/h, shift to fourth gear and sharply press the gas pedal. Observe the period during which detonation occurs in the form of ringing “fingers”, popping noises and other signs that are specific to your VAZ 2106 car. When accelerating, these sounds should stop. If this does not happen, it means that the ignition system of your VAZ car is “early”. This can be changed by turning the distributor clockwise by approximately half a division.
