Wiring diagram for contact ignition on a VAZ 2106

The contactless ignition system is a more advanced system compared to contact-transistor ignition. The main feature is that a contactless sensor is used instead of a contact breaker. In other words, the distributor breaker design eliminates the presence of contacts. As a result, such systems are called contactless.

At the same time, installing contactless ignition is possible even on those cars that initially had a contact system. For this reason, this solution is in great demand among owners of domestic cars (for example, contactless ignition of a VAZ). Next, we will look at how electronic ignition works and works, as well as what advantages of this type of ignition system can be identified.

Difference between factory device and electronic type system

Any ignition mechanism implies the same device. The electronic ignition connection diagram for the VAZ 2106 provides for the presence of many common elements. These are spark plugs, armored wires, a distribution device, a coil. The presence of candles is mandatory, because without them a spark will not form.

Armored wires are used to connect high-voltage parts. They are cords made of special fibers along which a power charge moves.

The ignition distribution device (distributor) is different for many cars. Its functions can be understood based on its name. The installation of contactless ignition for the VAZ 2106 is not complete without such an element.

The coil has the property of increasing the voltage supplied to the winding surface. Comparing the contact and electronic ignition of the VAZ 2106, it follows that the first is characterized by a central axis, which carries out its movement thanks to the drive mechanism from the oil pump. There is a small cam on the axis that participates in the operation of the contact block. This part also serves to transfer the power charge to the coil. Transmitting a large current requires the operation of the entire contact group, which complicates the process and leads to many problems.

The electronic ignition system of the VAZ 2106 requires a Hall sensor. This component serves as a contact breaker and has no direct contact. It also creates a weak impulse, which will not be able to ignite the upper winding surface of the coil. This device enhances the push and delivers at the right time.

A budget option for switching to a contactless system

The contacts of the mechanical breaker “burn out” and wear out, so they have to be periodically cleaned and the gap adjusted. Installing the Sonar IR module (costing 700÷900 rubles) in the distributor allows owners of classic VAZs (2101-2107) to be spared from this routine work.

The device consists of:

• optical sensor (infrared radiation source and photodetector);
• electrical signal amplifier;
• switching transistor.

Important! All of the above is mounted in a miniature waterproof housing, which makes it quite easy to install it in place of a standard contact breaker.

The operating principle of the module is as follows:

• When the distributor rotor rotates, its cams periodically block the light flux of the optical sensor.
• Electrical impulses from the photodetector are amplified by a built-in microcircuit and supplied to a control transistor, which opens/closes the circuit of the primary winding of the coil.

On a note! LED indicators (red and green) inform about the state of the electronic switching key (closed/open).

Disadvantages of the conventional ignition mechanism

Today, the contactless ignition system of the VAZ 2106 is used on many cars of this series. The contact mechanism is not available on newly produced vehicles. After all, this is due to the following shortcomings in the operation of the car and its parts :

• The occurrence of such a phenomenon as a spark jumping, which was reflected in their burning;
• Frequent cleaning;
• Short period of operation of the contact group;
• Frequent wear of the bearing on which the contacts are located, which led to instability of the engine;
• Stretching the balancers.

These shortcomings do not appear immediately, but one by one. Therefore, the owner of the “six” may be in constant repair. The structural structure of the contact group affects the charge power, reducing this value. As a result, the power unit begins to function worse and fuel consumption increases.

Therefore, car owners begin to think about the question - how to install electronic ignition on a VAZ 2106? And for those who have already done this, the topic is interesting - how to set the electronic ignition?

Design and operating principle of BSZ

So which ignition is better? Before we talk about installing and adjusting electronic ignition with our own hands, let's look at the operating principle of the BSZ and its design. So, the contactless ignition system is a rather complex device in design, which consists of many parts.

Among the main components it is worth highlighting:

• coil;
• vacuum and centrifugal voltage regulators;
• switching device;
• signal controller;
• high voltage wires;
• candles;
• accumulator battery.

These are the main elements that include the contactless ignition kit. As for the principle of operation, it is quite simple. When the driver turns the key in the lock, voltage begins to flow to the mounting block and here it is distributed between the starter, coil and other consumers of the car's current. The crankshaft begins to move, causing the signal controller to begin transmitting pulses to the switching node. The purpose of the latter is to stop the supply of voltage to the coil windings, due to which a higher voltage current is generated in the secondary turns.

BSZ diagram with designation of elements

This current makes it possible to generate a strong spark at the candles, which is subsequently used to ignite the combustible mixture. Current flows to the spark plugs in a certain order, in accordance with the position of the crankshaft. This process is carried out under the control of regulators, which can determine not only the frequency with which the shaft moves, but also the degree of load on the power unit. If the non-contact ignition system is adjusted properly, a high-power spark plug will form on the spark plugs, which will ensure normal ignition and combustion of the combustible mixture.

Advantages of electronic ignition

New contactless mechanisms do not have the negative qualities of the contact group, which affects their durability. The supplied pulse becomes stable and the fuel mixture ignites better. As a result, the installation of contactless ignition of the VAZ 2106 has a number of advantages :

• Reduced fuel consumption;
• Easier car starting at sub-zero air temperatures;
• Stability of engine operation at idle speed;
• Correct adjustment of the system will not require quick reconfiguration;
• Increased service life of spark plugs.

Assessing these advantages, we can say that the electronic ignition circuit of the VAZ 2106 has significant significance, which is felt upon first use. Moreover, many of the shortcomings that appear with a factory ignition will disappear.

Advantages of BSZ over KSZ

While writing the article, I sat and thought and thought, and still did not come to the conclusion of what exactly is the main advantage of BSZ; for me, all the advantages listed below are the main ones and are equal to each other.

So let's get started:

– High stability of engine operation (synchronous operation of the cylinders, strictly in turn)

– Frisky review of the throttle

– Better engine thrust (allowing you to easily use the largest drive sprockets without difficult acceleration!)

– Candles “live” four times longer than on KSZ (I’ll write about this separately below)

– Less well-known “snot” from Java mufflers (since fuel and oil are burned much better)

– Longer service life of all crank bearings (as there is less extraneous detonation and vibration)

– Less fuel consumption (since it burns out better, the carburetor must be adjusted to a lower fuel supply)

Selection of electronic ignition

The contactless ignition circuit for the VAZ 2106 depends on the type of power unit of the car. Various design features of the distribution element are provided. If a 1.3 liter motor is installed, the distributor has a shortened spindle. If you have a 1.5 L or 1.6 L engine, the distributor spindle is the same for these varieties. The delivery packaging of the contactless mechanism includes the following components:

• Distributor used for ignition distribution. In relation to the volume of the car engine, different articles are distinguished. For a 1.3-liter engine, a device with article number 38.3706-01 is required. Car engines of 1.5 l and 1.6 l should select an element with the designation 38.37061.
• A coil characterized by high voltage. It provides conversion of current not exceeding 12 V. The element serves to multiply low voltage. Can raise up to 20 kV. The article number of the device is 27.3705.
• Electronic type control module - designated 36.3734 or 3620.3734.

Wires are selected as connecting elements. It is possible to use a kit from Niva. The connection diagram for contactless ignition on a VAZ 2106 cannot be made using a contactless kit for a VAZ 2121. The distributor included in the kit for this brand is externally similar to the required device, but their technical indicators are different. Therefore, you should not use this device.

You also need to purchase candles. The gap between the electrodes should be 0.7-0.8 mm. They allow you to quickly ignite the air-fuel mixture in the cylinders.

Standard classic ignition system

Preparatory stage

Many people are interested in the question of how to install contactless ignition on a VAZ 2106 if there is no garage and inspection hole. But this device does not require an inspection hole; all operations can be performed near the hood. Additional auxiliary equipment required:

• Set of keys (for 8,10,13);
• Two screwdrivers - flat and Phillips;
• Pliers;
• Drill (use of drills for working with metal is allowed);
• Screws.

You can also borrow a spanner wrench that has a long handle. It will allow the crankshaft to rotate. If it is not found, then you can use the method of rotating the rear wheel, after placing the anti-recoil objects and turning on 4th or 5th speed.

When solving the problem of how to install electronic ignition on a VAZ 2106, first you need to carry out the preparation stage:

• Open the car hood;
• Remove the negative terminal of the battery;
• Remove the wires from the spark plugs and the distribution device;
• Unscrew the spark plugs.

Next, you need to prepare a new kit and begin the dismantling process.

Stages of replacing the contact mechanism

How to install contactless ignition on a VAZ 2106? First, the old mechanism is dismantled according to the following diagram:

• Remove the distributor cover and place its slider in a perpendicular position to the engine centerline. This is done by turning the starter off and on.
• Using a marker or chalk, make appropriate marks on the position of the slider.
• Disconnect the vacuum channel and wires from the distributor.
• Taking the key number 13, unscrew the fixing element of the coil-wire connection.
• Remove the wires from the coil. You need to remember in what position certain cores are located.
• Remove the coil.

It should be taken into account that when removing the distributor, the gasket located at the seating area of ​​the cylinder body may fall out.

The marks on the pulley and block must match

After the operations have been completed, the installation stage of the new kit begins:

• Having removed the spacer element from the old distributor, place it on the newly mounted device. Unfasten the distributor cap.
• Having rotated the slider, set it in the position that corresponds to that intended during previous operations.
• Place the distributor shaft into the socket and tighten the nut. Since in the future we will adjust the contactless ignition of the VAZ 2106, there is no need to use force when twisting it.
• Tighten the spark plugs and install the distributor cap.
• Install the wires to the desired cylinders.
• Install a new coil. If the contacts do not match, you need to loosen the clamp and unfold the housing.
• Remove the washer tank and make a couple of holes in the side member to secure the electronic module. It is worth ensuring that the module should not be located below the tank to prevent flooding with water.
• Connect the new module according to the attached diagram. And also connect old wires from the tachometer and other devices.
• Secure the vacuum tube.
• Start the car. If it is not possible to start, then you should change the position of the distributor to change the ignition timing.

Recent car models are equipped with mounting holes. After you have succeeded in setting the contactless ignition on the VAZ 2106, the process of setting the appropriate ignition timing begins

Signal generation by Hall sensor

The second possibility of contactless spark control can be achieved using a Hall sensor.
The Hall sensor is often used when converting the ignition system from contact to contactless, since it can be installed instead of a breaker on a movable plate.

The non-contact sensor uses the Hall effect (named after its discoverer), which involves the creation of a transverse potential difference in a conductor carrying a direct current under the influence of a magnetic field. The Hall effect is especially effective in special semiconductors. A microcircuit integrated into the Hall sensor further enhances the signal.

When the screen with slots (shutter) rotates, the magnetic field periodically acts on the Hall sensor. If the shutter is open between the magnetic guides (the so-called slots), a Hall voltage is induced. If the shutter is closed in the air gap between the magnetic guides, then the magnetic field lines cannot affect the Hall sensor and the voltage is close to zero (Small stray fields cannot be completely suppressed). Thanks to the Hall voltage characteristic, the signal for sparking is again present.

The number of slots corresponds in most cases to the number of cylinders, and the shutter rotates together with the ignition distributor rotor at a halved crankshaft speed. To regulate the ignition timing, the plate on which the Hall sensor is attached mechanically moves according to the already familiar principle. Sparking occurs when the Hall sensor is turned on (t2), that is, as soon as the slot allows the magnetic field lines to act on the Hall sensor. In this case, the ignition adjustment can be carried out with the engine not running (observe the manufacturer's information!).

Work on changing the ignition

How to adjust the electronic ignition on a VAZ 2106 after placing a new kit on the car? The first stage of adjustment is to configure the distributor:

• Remove the spark plug from the first cylinder;
• Place your finger on its hole;
• Rotate the crankshaft in a clockwise direction.

Adjustment of the electronic ignition on the VAZ 2106 is carried out when a stream of air begins to flow onto your finger. At this point you should stop turning. Next, the location of the distributor changes, namely, the slider should look towards the drive cylinder.

The next step in answering the question of how to set up electronic ignition on a VAZ 2106 is changing the ignition timing. This stage involves connecting the central coil wire to the spark plug and further shorting it to ground. The slider is turned in the opposite direction clockwise until a spark is formed. It is also necessary to ensure that this section is located at the point of interaction between the slider and the first cylinder.

How to set electronic ignition on a VAZ 2106 if detonation occurs? After equipping the car with the purchased kit and making adjustments, you need to warm up the car and press the gas, set second gear, listen to the engine. If there is no noise or detonation, then the setting is correct. In a situation where detonation occurs, the ignition must be adjusted later.

How to adjust contactless ignition on a VAZ 2106 if you need to adjust the leading angle using a strobe light. The device is connected to the machine voltage with preliminary removal and plug of the vacuum hose. After this, the engine should run to normal idle speed and loosen the bolt on the distributor. The strobe beam should fall on the crankshaft pulley. Rotate the distributor until the marks are located opposite the marks on the fuel mixture distribution cover. After this, secure the device.

Thus, now many will know how to install and how to set up contactless ignition on a VAZ 2106. The procedure can be performed independently if you have available tools and a set of a new device.

Installing electronic ignition on a VAZ 2106 is a way to modernize a car, which is often used in practice.

Structure and functions of BSZ

Based on the figure, the operating principle of the system is briefly explained:

Drawing. Components of a transistor ignition system

1. Accumulator battery
2. Ignition and starter switch
3. Ignition coil
4. Switch
5. Ignition sensor
6. Sensor-distributor
7. Spark plug

When the ignition (2) is turned on, supply voltage is supplied to the primary winding of the ignition coil (3). Current flows through the primary winding; as soon as the commutator (4) receives a signal from the ignition sensor (5), the current in the primary winding is interrupted. Terminal 1 of the ignition coil is connected to ground via a switch. A high voltage of more than 20 kV is induced in the secondary winding.

The secondary voltage of the ignition system is transmitted through terminal 4 of the ignition coil to the distributor sensor to the corresponding cylinder and spark plug.

The control unit determines the crankshaft rotation speed (sensor signals) and, based on it, controls the accumulation time of the current of the primary winding of the ignition coil (the duration of the open state of the output transistor or thyristor of the ignition system) and its magnitude. In accordance with the speed and voltage of the battery, shortly before the appearance of the ignition spark, the set value of the primary current is set, that is, as the speed increases, the duration of the current flow increases in the same way as when the battery voltage decreases.

When the ignition is turned on and the engine is not running (no sensor signal), after a while (usually after one second), the current in the primary winding of the ignition coil is turned off. As soon as the control unit receives a sensor signal (for example, during startup), it returns to operating status.

To adapt the ignition timing to different load conditions, adjustment is carried out in the same way as in contact ignition systems, mechanically through a membrane mechanism of a vacuum regulator, as well as a centrifugal regulator. As a result, the sensor signal (and with it the ignition timing) changes depending on the engine speed and load.

Inductive signal formation in a contactless transistor ignition system by storing energy in inductance

As a result of rotation of the rotor of the control pulse sensor, the magnetic field changes and an alternating voltage shown in Figure a, b is created in the induction winding (stator). In this case, the voltage increases as the rotor teeth approach the stator teeth. The positive half-cycle of the voltage reaches its maximum value when the distance between the stator and rotor teeth is minimal. As the distance increases, the magnetic flux sharply changes its direction and the voltage becomes negative.

At this point in time (tz), as a result of interruption of the primary current by the commutator, the ignition process is initiated.

We recommend: What is better to choose between a CVT, manual, automatic and robotic gearbox

The number of rotor and stator teeth in most cases corresponds to the number of cylinders. In this case, the rotor rotates at a reduced crankshaft speed. Peak voltage (± U) at low speed is approx. 0.5 V, at high - approx. up to 100 V.

The ignition timing can only be monitored when the engine is running, since without rotation of the rotor the magnetic field does not change and, as a result, no signal is created.

History of the VAZ 2106 car

The VAZ 2106 diagram gives motorists a detailed idea of ​​the location of the main components of the vehicle. This model is a small-class car (the version that was exported is Lada 2106) with a four-door body.

It is equipped with an engine with a displacement of 1.57 liters and a power of 75.5 hp. The motor is located in the front part, along the longitudinal axis. The history of the VAZ 2106 brand began in 1976. It was a modernized model 2103.

In the summer of 1998, production of cars and their modifications was stopped at AvtoVAZ OJSC, but, at the same time, began at RosLada in the city of Syzran. Since July 2001, this model began to be produced from vehicle kits at DOJSC Izhmash-Avto.

General information about the brand

Domestic cars of the 2106 brand were manufactured for the purpose of operating on roads equipped with improved surfaces, regardless of weather conditions. The cars are equipped with a four-door all-metal sedan body.

Cars are equipped with carburetor gasoline engines, four-speed or five-speed gearboxes. There is an independent spring front suspension; The rear suspension is dependent spring. The car's braking system is dual-circuit; there are disc brakes on the front wheels.

The rear ones are equipped with drums. Cars of the VAZ 2106 family were equipped with radial tubeless tires. The steering column has an anti-theft device that is built into the ignition switch.

The modification range of the VAZ 2106 family includes:

• VAZ 2106, 21065-00 - equipped with a model 2106 engine;
• 21061, 21065-01 – equipped with a model 2103 motor;
• 21063 – there was an engine from 21011.
• Car brand 21065 is the luxury version of this family. It has the following differences from the 2106 model: it is equipped with a five-speed gearbox and a final drive with a gear ratio of 3.9. Some cars were equipped with a Solex-type carburetor and a contactless ignition system. The car's electrical equipment is complemented by an electrically heated rear window, halogen headlights and a rear fog lamp. The body has been modified: the upholstery and seat headrests have been updated; The car is supplemented with bumpers of the 2105 model. Spare parts for the presented vehicles are available everywhere. In addition, the electric power steering is a kind of “novelty”, so to speak, the trends of the 21st century are making themselves felt. Thanks to this, car maintenance and repairs are not a big problem.

Setting up BSZ on a motorcycle

Almost any contactless ignition system available on the market or homemade is installed with strict control of ignition timing indicators. To facilitate installation and adjustment activities, we recommend using devices with a scale of up to 15 V, as well as internal resistance in the range of 10-50 kOhm.

An electronic auxiliary device, without which the contactless ignition circuit for a motorcycle cannot be properly implemented, will allow you to adjust the system without much hassle. In this case, the terminals of the device are connected to the Hall sensor.

The piston of any cylinder must be moved to a position that is characterized by sparking in the cylinder. Then the ignition is turned on and the modulator is turned in the direction in which the rotor is moving by the crankshaft. This must be done before changes occur in the voltmeter readings. The discharge on the spark plug occurs precisely when the voltage jump on the sensor reaches approximately the level of the on-board power supply of the motorcycle. When you catch a spark, there is no need to disturb the position of the curtains. The modulator itself is securely fixed on the generator shaft using a mounting bolt. When adjusting the ignition, it is necessary to short-circuit all high-voltage wires on the motor housing. You can attach them to candles. This is necessary so that the operation of coils with a broken secondary circuit does not lead to a complete overload or damage to the BSZ. For many people, online slot machines are one of the ways to relax after a grueling day at work. The official website of the Pin Up casino provides all visitors with a variety of slots of different themes. Play for money or for free – everyone decides for themselves individually! . In addition, according to the above risk, you should not stop the engine by removing the spark plug caps. All these are recommendations, of course, in practice you may be lucky, but you should not tempt fate.

The motorcycle's contactless ignition system can be tested after adjustment. You can verify the presence of a spark by securing the wire being tested approximately 8 mm from the motorcycle engine body. Next you need to turn on the ignition and use the kick starter to start the engine. It is better not to touch the wire with your hands. After all, it can give you a strong electric shock.

After careful adjustment and tuning, BSZ motorcycle equipment will last a very long time without additional maintenance.

Now take another look at how simple the contactless ignition circuit for a motorcycle looks close up.

Ignition circuit for VAZ 2106

The VAZ 2106 ignition circuit includes an ignition distributor, a coil, spark plugs, a lock and low and high voltage wires. The VAZ 2106 connection diagram for this car system is shown in the photo.

1. Until 1980, machines of this brand were equipped with the R-125B distributor. It was installed together with carburetors of type 2103. This distributor had a mechanical octane corrector, with which it was possible to slightly change the ignition timing, however, at the same time, there was no special vacuum regulator. After 1980, when engines were equipped with carburetors 2107-1107010-20 (“Ozone”), they began to use a 30.3706 distributor, which had a vacuum ignition timing regulator.
2. The coil used was type B117-A. There was an open magnetic circuit. The device is oil-filled and sealed.
3. Spark plugs of type A17DV or similar ones, but of foreign manufacture, were used.
4. The cars were equipped with a VK347 lock, which had an anti-theft device. It works as follows: when the key is removed (from position III “Parking”), the locking rod extends from the switch body in a special way. It fits into the groove of the steering shaft and thus the shaft is blocked.

Why is it needed and what is it like?

To understand why the contact system needed to be changed to a non-contact one, let’s touch a little on the principle of operation of an internal combustion engine. A mixture of gasoline and air is supplied during the intake stroke when the piston moves to bottom dead center. Next, the intake valve closes and the compression stroke begins. In order for the motor to achieve maximum efficiency, it is extremely important to determine the moment when you need to send a signal to generate a high-voltage pulse.

In contact systems in the distributor, during shaft rotation, the breaker contacts are closed/opened, which are responsible for the moment of energy accumulation in the low-voltage winding and the formation of high voltage current. In the contactless version, this function is assigned to the Hall sensor. When the coil has formed a charge, when the distributor contact (in the distributor cover) closes, this impulse travels along the corresponding line. In normal mode, this process takes enough time for all signals to arrive at the contacts of the ignition system. However, when the engine speed increases, the classic distributor begins to work unstable.
