Setting the electronic ignition on the VAZ 2106. Installing the electronic ignition on the VAZ

How does the contactless system work? Its functioning is carried out as follows:

the primary winding of the ignition coil is connected to the generator and the car battery through the switch, and is always under high voltage. As soon as the Hall sensor detects the approach of the piston to the top dead center, it is disconnected from the battery;
after breaking the electrical circuit, a pulse discharge occurs in the secondary winding of the coil. It is he who is transmitted to the distributor through the high-voltage wire;
the distributor slider transfers the impulse further to the spark plug of the cylinder, the piston of which was fixed by the sensor;
a spark occurs, which leads to the ignition of the air-fuel mixture;
the Hall sensor detects the passage of the piston top dead center, and the circuit is closed again. The process is cyclical and repeats 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 handle.

It is carried out in the sequence described below:

set the piston of the first or fourth cylinder to top dead center;
we remove the distributor. In this case, it is advisable to remember the position of the slider, as well as replace the high-voltage wires in order to avoid problems during the subsequent stages;
we put 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 the immediate vicinity of the distributor in a specially designed place. We connect the connector with wires.

Today, in specialized stores, you can easily purchase a complete set of electronic ignition for installation on VAZ-2106 cars. If, for some reason, you are forced to buy system parts separately, we strongly recommend that you pay special attention to choosing a distributor.

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

Electronic ignition setting

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

slightly loosen the nut holding the distributor. In this case, the engine should work in normal mode;
we turn the distributor in different directions, trying to achieve the most stable operation of the motor, determining it by ear;
as soon as the goal is achieved, we tighten the nut until it stops.

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

Engine operation directly depends on the health of the ignition and fuel supply systems. They determine engine power, fuel consumption, throttle response, and ease of starting. Failure to adjust the ignition timing of a carburetor engine leads to detonation, glow ignition, an increase in the exhaust temperature and a rapid failure of the unit. There are several ways to set the ignition on a VAZ 2106. All of them are simple and accessible to a novice car enthusiast.

Ignition system device on classic VAZ engines

The motors installed on the VAZ 2106 differ in displacement, but have the same design. Trambler, timing parts, front cover with marks and crankshaft pulley are interchangeable during repair. There are contact (KSZ) and non-contact (BSZ) ignition systems. In the first case, the contacts are opened mechanically when the distributor shaft is turned by 90 0. In the second version, a Hall sensor and a controller are used, which allows you to accurately determine the moment the spark is supplied to the cylinders.

The simplest contact system consists of the following elements:

Ignition lock, also known as a switch;
Ignition coil with two windings for high voltage production;
A mechanical breaker that opens the primary winding of the coil at the right time;
Rotor and contact cover for voltage distribution to spark plugs;
Centrifugal and vacuum regulators;
Transistor for reducing the current in the primary winding and extending the service life;
Spark plug;
High voltage wires.

Contact ignition circuit: 1 - generator, 2 - ignition switch, 3 - ignition distributor, 4 - breaker cam, 5 - spark plugs, 6 - ignition coil, 7 - storage battery

The principle of operation of any ignition system is as follows. At the moment when the piston in the cylinder is in the upper position and compresses the fuel mixture as much as possible, the coil windings are opened. The high voltage through the distributor cap travels through a high-voltage wire to the corresponding spark plug, on the electrodes of which a powerful spark is generated. Ignition occurs. This process is called the piston stroke.

With an increase in engine speed, the ignition timing (IOP) changes, and the centrifugal regulator makes the angle optimal. The vacuum regulator shifts the angle depending on the vacuum in the intake manifold. This allows you to achieve optimal power in all engine operating modes.

Malfunction symptoms

Ignition adjustment on the car is required after repairing the engine or removing the distributor. Like any mechanical system, it tends to wear out, characteristic symptoms appear:

Engine does not start or runs intermittently. If gasoline enters the carburetor, then the reason lies in the incorrect setting of the ignition angle or displacement of the marks on the timing chain.
Decrease in acceleration dynamics and deterioration of the elasticity of the motor. The mixture ignites not at the optimum time, therefore the efficiency decreases.
Increased fuel consumption. This happens with late ignition, when, to obtain the same dynamics, you have to more actively press the gas pedal. Part of the gasoline does not have time to burn and flies out into the exhaust pipe.
Late ignition is the cause of muffler popping when the unburned fuel mixture ignites when the exhaust valve opens.
Rough engine operation is possible with early ignition of gasoline in the cylinders. An explosion at the moment the piston does not reach TDC is the cause of the characteristic rattling sound and ringing.

Attention! Late ignition often causes burnout of the exhaust valves, which overheat at this moment.

Having found a malfunction, you should check that the ignition is installed on the VAZ 2106, and, if necessary, adjust it. For work, you need a candle key, a key for "13", a light bulb or stroboscope, a plate probe.

Instructions for setting the ignition VAZ 2106

Let us analyze 3 known methods of adjusting the ignition angle on VAZ engines.

With a stroboscope (by marks)

This method allows you to very accurately set the ignition according to the marks, and does not require removing the distributor and valve cover. The entire adjustment process takes 5 minutes. A stroboscope can be found in any car dealership. The procedure is as follows:

On a muffled car, we loosen the distributor mounting nut, having previously made a mark on its initial position on its body;
On the front cover of the engine, we find two short and one long mark, clean them of dirt and oil;
We connect the negative wire of the stroboscope to the engine "mass", the positive wire to the ignition coil, and a special clip to the high-voltage wire of the first cylinder;
We start the engine and turn on the stroboscope. The light from its lamp, directed to the pulley, will show the true position of the ignition moment;
Slowly turning the distributor body, we achieve the alignment of the mark on the crankshaft pulley and the tides on the front cover;
We check the engine speed by the tachometer and, if necessary, adjust the idle speed on the carburetor;
We tighten the distributor fixing nut.

The “4” mark on the pulley must be aligned with the mark you need on the cover. Mark "1" corresponds to an angle of 10 0, "2" - 5 0, "3" - 0 0

The labels have a value at 0 0, 5 0 and 10 0 relative to the top dead center (TDC). For correct operation on 92 gasoline, an advance of 0 degrees is selected.

Light bulb installation

If there was no strobe at hand, and the ignition needs to be set accurately, it is recommended to use a simple 12-volt car lamp. Two wires with stripped contacts are soldered to it. The settings are made in the following sequence:

Advice! Instead of a signal lamp, a voltmeter is used, which is connected in the same way. By rotating the distributor body, we look for a position in which there is no voltage.

We set the ignition by ear

It is possible to quickly adjust the approximate position of the distributor without any devices. It takes a little patience and good hearing. This method is applicable only if the carburetor and timing are in good condition. We act in this way:

We start the engine, let it warm up to operating temperature, the throttle handle in the carburetor must be recessed;
We slightly loosen the distributor fasteners and begin to gently turn it;
When turning at large angles, the engine will stall or, on the contrary, increase the speed;
It is necessary to achieve smooth idle speed in the range of 700-800 rpm without extraneous knocking and detonation;
In this position, we fix the distributor.

Such adjustment by ear requires checking on the road or with a stroboscope, but for the initial adjustment, this is the best option.

How to install a contactless (electronic) ignition

Installing an electronic ignition is the easiest way to improve engine performance. Replacing with a contactless system gives the following advantages:

Confident cold start;
Stable engine operation at any speed;
High reliability;
The service life of the spark plugs is increased;
Powerful spark;
No clearance adjustment and no centrifugal adjuster required.

The complete set includes a distributor with a Hall sensor, a special ignition coil and a switch. It is possible to leave old high-voltage wires.

The electronic ignition system includes: an ignition coil, a distributor, a switch and a set of wires

To install a contactless ignition instead of the old one, we need a key for "13" and "10", two screws for attaching the switch and a stroboscope for adjusting the lead angle.

The order of the work performed:

Important! BSZ systems may differ in the length of the distributor shaft for different models of classic Zhiguli engines, so before buying it is worth checking with the seller about the interchangeability of components.

Checking the ignition angle while driving

It is best to check the performance of the ignition system after any adjustment on the move. This is due to the design features of the distributor and the octane rating of the gasoline used. It so happens that the firing angles set according to the marks do not give sufficient dynamics and throttle response. Adjustment by ear at the beginning of detonation will help:

We accelerate the car to a speed of 45-50 km / h on a flat section of the road;
We turn on the direct transmission (on the VAZ 2106 fourth) and press the gas pedal all the way;
A characteristic ringing (detonation) should appear, which will disappear after 2-3 seconds, and the acceleration will be smooth and powerful without failures;
If the detonation does not disappear during the entire acceleration, then the ignition angle is "early";
The complete absence of ringing and sluggish dynamics indicate a delay in the spark in the cylinders;
We adjust the position of the distributor in place, turning it 3-5 degrees;
When the adjustment is completed, the position of the distributor body relative to the block is marked with a line or paint.

Ignition adjustment work should be carried out regularly. The service interval for a simple contact ignition system is 15,000 km, for an electronic one - twice as long. The condition of the spark plugs and high-voltage wires is also regularly checked. All setup operations can be easily done by yourself, no garage is needed for this. The skill of self-repairing the ignition of the VAZ 2106 will always come in handy on a long journey or in winter when problems arise with starting.

It should be noted right away that the installation of an electronic (contactless) ignition on a VAZ "classic", despite some investments, is economically justified. As a result of the replacement, a certain saving in fuel consumption is achieved due to a good start in the cold season, more stable idle operation and more accurate ignition timing.

Although BSZ (non-contact ignition system) kits are now being sold, it is still worth listing the parts necessary for installing electronic ignition VAZ 2106, 2101,2104, 2107, 2105, 2103 these are:

ignition coil (027.3705 or analogue 27.3705);
distributor with Hall sensor (38.3706);
switchboard VAZ 2108 (036.3734);
set of candles (A 17DV-10);
wiring harness (ignition bundle VAZ 2108).

Ignition installation VAZ 2106, 2101,2104, 2107, 2105, 2103

first of all, it is necessary to set the TDC - 4 cylinders (we look at the position of the slider), this must be done by turning the crankshaft ratchet to the mark on the pulley, we combine marks 4 and 3 in the figure);

dismantle the distributor, candles and the coil (remembering the color of the wires suitable for the ignition coil);
we lay new wiring;
install a new high-voltage ignition coil;
we put the distributor exactly as the old one was (the installation of electronic ignition of vaz 2106,2103, 2107 with engines of 1.5 and 1.6 liters is slightly different from other models. These engines have different cylinder block heights and, accordingly, different length of the distributor drive shaft);
we fix the switch (it is advisable to find a place on the shield of the engine compartment);
we screw in the candles and put on high voltage wires (operating procedure 1-3-4-2);
we connect the wiring as in the diagram:

Adjustment

The initial setting of the VAZ ignition angle is as follows:

it is necessary to install the crankshaft pulley at the ignition timing mark of 10 degrees.
we put the distributor exactly so that the Hall sensor looks at the beginning of the distributor slot.
we start and warm up to operating temperature.
we try to run on hot (if the ignition is too early, the starter will not turn as expected)

Test drive: you need to pick up a speed of 30-40 km / h, turn on 4th gear and give full throttle. You should hear the ringing of "fingers" for 2-3 seconds, and then the engine should pick up speed evenly. If the ringing lasts longer, it is necessary to advance the ignition later by turning the distributor slightly counterclockwise. If there is no ringing, you can do it a little earlier - by turning it clockwise.

Dual-circuit electronic ignition on the VAZ 2107:

Why is there no mention of a stroboscope here?

The fact is that specialists in practice do not use a stroboscope due to the constant stretching of the chain on the engine. Even a new chain for 10-15 thousand mileage, after being tightened with a tensioner, is stretched so that the marks on the motor do not match, so it is impossible to accurately set the ignition with a stroboscope.

Finally. Installation of electronic ignition of a VAZ 2107, with an injection engine is NOT POSSIBLE, since it is already installed. If a wiring harness from a VAZ 2108 was installed and the car does not start, then, most likely, the connectors of the switch and EPHH were confused, they are identical.

The topic of the article is contactless ignition of domestic cars. But in order to understand the principle of the functioning of this system, it is necessary to find out what preceded this design. Or, more precisely, what systems were before contactless. And there were several of them, so you need to briefly consider each. And you need to start with the very first - contact.

Contact ignition system

Oldest design not currently used in the automotive industry. True, the contactless ignition circuit is also outdated, it can be found only on scooters and walk-behind tractors. But most of the cars equipped with a carburetor fuel injection system have contactless ignition. But it's worth talking about the contact. In it, the main unit is the distributor in which the breaker is installed.

The breaker has small dimensions, serves to open and close the circuit that feeds the coil. The disadvantages are that a spark gap is formed. Unfortunately, no arcing system is provided. And despite the low value of the voltage flowing through the contacts, they quickly become covered with carbon deposits. The spring force also acts, due to which the contacts are gradually erased. Therefore, from time to time it is necessary not only to change this unit, but also to make its adjustment.

Contact transistor

This design is already slightly better. Of course, the VAZ-2106 contactless ignition is built somewhat differently. The system uses the same breaker driven by the eccentric axis of the distributor. But there is a small nuance - low voltage switching occurs. For comparison: in the previous design, 12 volts are switched, and in this one no more than two. The system was not widely adopted, although it is more perfect. It is possible to get rid of the burning of the contact group.

But the main drawback remained - mechanical wear. The breaker supplies a low voltage to an electronic switch made on a semiconductor transistor. The latter also produces high voltage and current switching. Of course, now someone will decide that a conventional relay can be adapted for this purpose. But right away it is worth dispelling all dreams - it cannot be installed here. The reason for this is the high frequency of the breaker. An electromagnetic relay will not be able to provide reliable switching.

Non-contact system

And now we need to talk about the advantages of contactless ignition of 2106 and other classic models. Firstly, it can be installed on any engine with a carburetor injection system. Secondly, there is the possibility of increasing the power and stability of work. Thirdly, there is no need for constant adjustments and monitoring of the vehicle ignition system. Perhaps, only these main advantages are enough for your choice to fall on just such a design. In addition, no alterations are required. You just need to replace all the components with new ones, adapted to your car. Installation will be discussed below.

Hall Sensor

This is one of the main elements that make up the BSZ. It plays a key role, since it is with its help that a signal is sent to the control system. All engine cylinders work synchronously, the voltage on the spark plug electrodes must be applied in a timely manner. And the moment when it is necessary to generate the next portion of high voltage is determined by the Hall sensor.

Perhaps this is one of the few reading devices that are installed in carburetor engines. Hall sensor is mounted in the distributor housing. It controls the movement of a cylindrical metal plate attached to the valve shaft. It has four petals of the same size and shape. To put it simply, the Hall sensor "sees" the presence or absence of metal in its area of \u200b\u200baction.

Switch

The second main element is an electronic switch. With its help, the signal from the Hall sensor is amplified to the operating value. At the output, a signal is generated, amplified to such an extent that it is enough to excite the primary winding of the ignition coil. It would seem that a simple contactless ignition circuit is complicated precisely by the switch. But not everything is so bad in reality. Of course, if this component suddenly fails, the car will be unstable at best. At worst, it will stop turning on.

It is useless to repair it, since its body is filled with epoxy resin, it is enclosed in a plastic case on the outside, and an aluminum radiator is located at the back. And if suddenly on the way your switch failed, then you need to buy a new one. As an option - always have with you devices that simulate the operation of the switch and the Hall sensor. True, with them it will be possible to accelerate to a maximum of 90 km / h, but you can get to the nearest service or auto parts store without any problems.

Ignition coil and other elements

In a contactless system, it is somewhat different from that used in the classical one. The reason is the different value of the secondary voltage. So, when an internal combustion engine is operating with a contact (including contact-transistor) ignition system, 25-30 thousand volts are required to form a spark gap. But in a contactless system, you need to generate over 30 kV, sometimes even up to 40 kV. Therefore, more turns are needed in the secondary.

The rest of the elements are completely similar in all three above-considered designs. The armored wires connecting all high-voltage circuits are up to you to choose. They can be either in silicone or rubber sheath. Contactless ignition 2107 can work with any high-voltage wires recommended by the manufacturer. Candles must be used those recommended by the manufacturer. In this case, you can again choose the brand yourself.

Installation of the system on a VAZ 2106-2107

And now a few words about how to make the transition from a contact ignition system to BSZ. In fact, nothing is easier, you just need to purchase a new distributor, switch and connecting wires in the store. Moreover, all these elements are sold as a set. And along with them comes a small sheet, which shows the connection diagram of all the components. You just have to read the brief instructions and install.

Attach the switch to the body with two self-tapping screws. If you wish, you can weld on two studs so that later the replacement is carried out faster. Instead of the old distributor, put a new one. Replace the coil as well. Connect the armored wires to the cover. The switch must be connected to the ignition switch. Or, more precisely, with the conclusion on which tension appears when the key is turned. You connect the Hall sensor to the switch, from the last wire you throw it to the output of the primary winding of the coil.

Conclusion

That's all, now you know what contactless ignition of the VAZ-2106 and similar models is, how it differs from previous systems. Even the rules of installation on the car have been studied. Do not forget only that you need to adjust the ignition timing before starting the engine for the first time. This can be done with a stroboscope or oscilloscope.

The electronic sparking system appeared only on the latest modifications of the rear-wheel drive "classic" VAZ 2106. Until the mid-90s, these cars were equipped with ignition with a mechanical interrupter, which is very unreliable in operation. The problem is solved relatively easily - the owners of outdated "sixes" can purchase a contactless ignition kit and install it on the car on their own, without contacting the electricians.

Electronic ignition device VAZ 2106

The non-contact system (abbreviated - BSZ) "Zhiguli" includes six devices and parts:

main distributor of ignition pulses - distributor;
a coil that generates a high voltage for a spark;
switch;
connecting loop of wires with connectors;
high voltage cables with reinforced insulation;
spark plug.

BSZ inherited only high-voltage cables and candles from the contact circuit. Despite the external resemblance to the old parts, the coil and distributor are structurally different. New elements of the system - control switch and wiring harness.

The coil operating as part of the contactless circuit differs in the number of turns of the primary and secondary windings. Simply put, it is more powerful than the old version, since it is designed to create pulses of 22-24 thousand volts. The predecessor gave a maximum of 18 kV to the spark plug electrodes.

Trying to save money on the installation of electronic ignition, one of my friends replaced the distributor, but connected the switch to the old coil of the "six". The experiment ended in failure - the windings were burned out. As a result, I still had to buy a new type of reel.

A ribbon cable with connectors is used to securely connect the terminals of the ignition distributor and the switch. The device of these two elements should be considered separately.

Contactless distributor

The following parts are located inside the valve body:

shaft with platform and slider at the end;
a support plate pivoting on a bearing;
hall magnetic sensor;
a metal screen with gaps is fixed on the shaft, rotating inside the sensor gap.

Outside on the side wall there is a vacuum ignition timing unit connected to the support platform by means of a thrust. A cover is fixed on top of the latches, where the cables from the candles are connected.

The main difference between this distributor is the absence of a mechanical contact group. The role of the breaker here is played by an electromagnetic Hall sensor, which reacts to the passage of a metal screen through the gap.

When the plate covers the magnetic field between the two elements, the device is inactive, but as soon as a gap opens in the gap, the sensor generates a direct current. How the distributor works as part of an electronic ignition, read below.

Control switch

The element is a control board protected by a plastic cover and attached to an aluminum cooling radiator. In the latter, 2 holes are made for mounting the part to the car body. On the VAZ 2106, the switch is located inside the engine compartment on the right side member (in the direction of the car), next to the coolant expansion tank.

The main functional parts of the electronic circuit are the power transistor and the controller. The first one solves 2 problems: it amplifies the signal coming from the distributor and controls the operation of the primary winding of the coil. The microcircuit performs the following functions:

gives commands to the transistor to break the coil circuit;
creates a reference voltage in the electromagnetic sensor circuit;
counts engine speed;
protects the circuit from high-voltage impulses (over 24 V);
adjusts the ignition timing.

The switch is not afraid of polarity reversal if the motorist mistakenly confuses the positive wire with "ground". There is a diode in the circuit that closes the line in such cases. The controller will not burn out, but simply stop functioning - a spark will not appear on the candles.

Scheme and principle of operation of BSZ

All system elements are interconnected with each other and with the engine as follows:

the distributor shaft rotates from the motor drive gear;
hall sensor installed inside the distributor is connected to the commutator;
the coil is connected with a low voltage line to the controller, high - with the central electrode of the distributor cover;
the high voltage wires from the spark plugs are connected to the side contacts of the main distributor cover.

Threaded clamp "K" on the coil is connected to the positive contact of the ignition switch relay and terminal "4" of the commutator. The second clamp marked "K" is connected to the contact "1" of the controller, here comes the tachometer wire. Terminals "3", "5" and "6" of the commutator are used to connect the Hall sensor.

The algorithm of work of the BSZ on the "six" looks like this:

After turning the key in the lock voltage is applied to electromagnetic sensor and the first winding of the transformer. A magnetic field is generated around the steel core.
The starter motor turns the engine crankshaft and the distributor drive. When a screen cut passes between the sensor elements, a pulse is generated that is sent to the commutator. At this moment, one of the pistons is close to the top point.
The controller opens the primary coil circuit by means of a transistor. Then, in the secondary, a short-term pulse of up to 24 thousand volts is formed, which goes along the cable to the central electrode of the distributor cover.
Having passed through the movable contact - the slider, directed towards the desired terminal, the current flows to the side electrode, and from there - through the cable to the candle. A flash is generated in the combustion chamber, the fuel mixture ignites and pushes the piston down. The engine starts.
When the next piston reaches TDC, the cycle repeats, only the spark is transferred to the other candle.

For optimal fuel combustion during engine operation, the flash in the cylinder should occur a fraction of a second before the piston is in the maximum upper position. For this, the BSZ provides for sparking advance by a certain angle. Its value depends on the speed of the crankshaft and the load on the power unit.

The switch and the vacuum block of the distributor are engaged in the adjustment of the lead angle. The first one reads the number of pulses from the sensor, the second one acts mechanically from the vacuum supplied from the carburetor side.

Proximity system malfunctions

In terms of the reliability of the BSZ operation, it significantly surpasses the outdated contact ignition of the "six", problems arise much less often and are easier to diagnose. System malfunction symptoms:

complete failure - the engine stalls and will no longer start;
uneven idle, shots into the carburetor when the gas pedal is pressed sharply;
interruptions and skipping cycles while driving.

The most common first symptom is engine failure, accompanied by the absence of a spark. Common causes of the problem:

The high-voltage coil is extremely rare. Symptoms are similar - complete absence of a spark and a "dead" motor.

The search for the "culprit" is carried out by sequential measurements at different points. Turn on the ignition and use a voltmeter to check the voltage at the Hall sensor, transformer contacts and switch terminals. The current must be supplied to the primary winding and 2 extreme contacts of the electromagnetic sensor.

To test the controller, a familiar auto electrician suggests using one of its functions. After turning on the ignition, the switch supplies current to the coil, but if the starter does not rotate, the voltage disappears. At this moment, you need to take a measurement using a device or a control lamp.

Hall sensor malfunction is diagnosed as follows:

When the engine runs intermittently, you need to check the integrity of the wiring, contamination of the switch terminals or high-voltage wires for insulation breakdown. Sometimes a delay occurs in the switch signal, causing dips and deterioration of the acceleration dynamics. It is quite difficult for an ordinary owner of a VAZ 2106 to find such a problem; it is better to contact an electrician.

Modern controllers used for contactless ignition of the "six" burn out quite rarely. But if the Hall sensor test gave a negative result, then try to replace the switch by elimination. Fortunately, the price of a new spare part does not exceed 400 rubles.

Installation of BSZ on VAZ 2106

When choosing a contactless ignition kit, pay attention to the engine size of your "six". The distributor shaft for a 1.3 liter engine should be 7 mm shorter than for more powerful 1.5 and 1.6 liter power units.

To install BSZ on a VAZ 2106 car, you should prepare the following set of tools:

open-end or cap wrenches with dimensions of 7-13 mm;
flat and Phillips screwdrivers;
pliers;
a drill with a 4 mm drill (to mount the electronic unit in the spar, you will have to make 2 holes for self-tapping screws).

I highly recommend purchasing a 38mm long handle spanner for unscrewing the ratchet. It is inexpensive, within 150 rubles, it is useful in many situations. Using this key, it is easy to turn the crankshaft and set the pulley marks to adjust the ignition and timing.

The first step is to dismantle the old system - the main valve and the coil:

Pull the high-voltage wires out of the distributor cover sockets and disconnect it from the case by unlocking the latches.
While turning the crankshaft, set the slider at an angle of approximately 90 ° to the engine and place opposite the mark on the valve cover. Unscrew the 13 mm nut securing the distributor to the block.
Unscrew the clamps of the old coil and disconnect the wires. It is advisable to remember or sketch the pinout.
Loosen and unscrew the clamp fastening nuts, remove the coil and the distributor from the car.

When removing the ignition distributor, keep the washer-shaped gasket installed between the part pad and the cylinder block. It can be useful for a contactless distributor.

Before installing BSZ, it is worth checking the condition of high voltage cables and candles. If you doubt the performance of these parts, it is better to change them immediately. Serviceable candles must be cleaned and set a gap of 0.8-0.9 mm.

Install the contactless kit according to the instructions:

Remove the BSZ distributor cover, if necessary, move the sealing washer from the old spare part. Turn the slider to the desired position and insert the distributor shaft into the socket, lightly press the platform with a nut.
Put on the cover, locking the latches. Connect the spark plug cables according to the numbering (the numbers are indicated on the cover).
Screw the coil of the contactless system to the body of the VAZ 2106. In order for the terminals "B" and "K" to be in their original position, first unfold the body of the product inside the fastening clamp.
Put on the contacts the wires from the ignition switch and the tachometer according to the diagram above.
Install the controller next to the side member by drilling 2 holes. For convenience, remove the expansion tank.
Connect the wire harness to the distributor, switch and transformer. The blue core is connected to the "B" terminal of the coil, the brown one - to the "K" contact. Place the high voltage cable between the distributor cover and the center electrode of the transformer.

If during the installation process there were no annoying mistakes, the car will start immediately. The ignition can be adjusted "by ear" by loosening the distributor nut and slowly turning the body at idle speed of the engine. Make the motor run as smoothly as possible and tighten the nut. Installation is over.

Setting the ignition timing

If, before disassembling, you forgot to put a risk on the valve cover or did not align the marks, you will have to re-adjust the sparking moment:

Remove the plug of the first cylinder and discard the main distributor cap.
Insert a long screwdriver into the spark plug well and turn the crankshaft by the ratchet with a wrench clockwise (as viewed from the front of the machine). The goal is to find the TDC of the piston that will push the screwdriver out of the well as much as possible.
Loosen the nut holding the distributor to the block. Rotate the housing until one of the screen slots is in the gap of the Hall sensor. In this case, the movable contact of the slider must clearly align with the side contact "1" on the distributor cover.
Tighten the distributor mounting nut, install the cover and spark plug, then start the engine. When it warms up to 50-60 degrees, adjust the ignition "by ear" or by a stroboscope.

Attention! When the piston 1 of the cylinder is in the upper position, the notch of the crankshaft pulley should coincide with the first long line on the timing case cover. Initially, you need to provide a lead angle of 5 °, so set the pulley mark opposite the second risk.

In the same way, tuning is performed by a light bulb connected to the ground of the car and the low-voltage winding of the coil. The ignition moment is determined by the flash of the lamp when the Hall sensor is triggered and the switch transistor opens the circuit.

I happened to be in the wholesale car parts market and bought an inexpensive strobe. This device greatly simplifies the ignition setting, showing the position of the pulley notch when the engine is running. The stroboscope is connected to the distributor and gives out flashes simultaneously with the formation of a spark in the cylinders. By aiming the lamp at the pulley, you can see the position of the mark and its change with increasing revolutions.

Electronic spark plugs

When installing BSZ on a VAZ 2106 model car, it is advisable to select and install candles that are optimally suited for electronic ignition. Along with Russian spare parts, the use of imported analogues from well-known brands is allowed:

original candles recommended by the manufacturer - А17ДВР (М);
NGK - BCPR6ES-9, BPR6ES-9;
Bosch - FR7DCU, WR7DC;
Brisk DR15YC, LR15YC;
Beru - 14FR-7DU, 14R-7DU.

The letter M in the marking of the domestic part indicates the depletion of the electrodes. On sale there are A17DVR kits without copper coating, which are quite suitable for BSZ.

The gap between the working electrodes of the candle is set within 0.8-0.9 mm using a flat dipstick. Exceeding or decreasing the recommended clearance leads to a decrease in engine power and an increase in gasoline consumption.

The installation of a non-contact sparking system noticeably improves the operational characteristics of the carburetor Zhiguli equipped with rear wheel drive. Unreliable, eternally burning contacts caused a lot of trouble for the owners of the sixes. At the most inopportune moments, the breaker had to be cleaned, getting your hands dirty. The first electronic ignition appeared on front-wheel drive models of the "eighth" family, and then migrated to the VAZ 2101-2107.
