Replacing contact ignition with contactless VAZ 2106. Correct ignition setting on the "Six": instructions for owners. Advantages of a non-contact ignition system

Today, many owners Classics (Vaz-2101, Vaz-2102, Vaz-2104, Vaz-2105, Vaz-2106, Vaz-2107) installed on their cars contactless electronic ignition... And this is natural. Advantages demon contact ignition obvious and proven in practice. For example: ease of installation and adjustment, reliability and accuracy of operation, significant improvement in engine starting in the cold season. It seems to me that the list of "pluses" is not bad !? And if you are not a conservative, you were pretty fed up with the "quirks" of the contact pair and for certain reasons, you have not yet decided to buy a contactless ignition kit, then this article (I hope) will help you take the last step. Since, in fact, you should not have big difficulties and problems when installing the "new thing". For example, it seems to me that the biggest problem is the purchase of the kit itself. After all, you need to force yourself to part with a tidy sum;)))

Now from the introduction, let's move on to the main thing. Choosing, buying and installing on your beloved and invincible Classics (Vaz-2101, Vaz-2102, Vaz-2104, Vaz-2105, Vaz-2106, Vaz-2107) kit contactless electronic ignition .

Choice and purchase: from myself I can advise you to opt for a set contactless ignition of Russian production, the city of Stary Oskol- look at photo 1. In the box we find - coil, switch, distributor and wiring harness(photo 2). In terms of quality, this kit is considered one of the best. True and the price, "bites"))) Also, look at which engine block you have, since the distributors are of two types (differ in the length of the shaft) - for the engine Vaz-2101, Vaz-2102, Vaz-2104, Vaz-2105 and Vaz-2103, Vaz-2106, Vaz-2107.

Preparing for installation- a drill, a drill and a pair of self-tapping screws (a standard mounting place is provided for the coil in the engine compartment, but the switch will have to be fixed independently), a 13 spanner, an 8 and 10 spanner or socket wrenches. "You need a key for 38.

We can start replacing:

We take the 38 key and turn the ratchet nut until the marks on the crankshaft pulley and the front engine cover coincide, that is, we set the engine to the “TDC” mark (photo 3).

We remember the location of the distributor and the slider; the new distributor will be placed in this position. In my case, the slider is turned to valve cover and "stands on the fourth cylinder" on the distributor cap (photo 4). This is his correct position.

We also find the B + mark on the coil and remember which wires are screwed to it (photo 5). Then we unscrew and remove the coil.

Using a 13 key, unscrew the distributor lock nut and remove it. We try not to lose the gasket - photo 6.

We fix the switch, fasten the black wire “to ground” (photo 7). We install and fix the coil to the body. We connect standard wires to the corresponding terminals (pay attention to the location of terminals B and K on the new coil - photo 8). The wires from the switch are marked with + to terminal B, the second wire to terminal K - photo 9.

We install the distributor, do not fully tighten the lock nut. We connect the wires from the switch to the distributor (photo 10). We check the position of the distributor and the slider (photo 11), put on the cover and connect the wires in the order 1-3-4-2 (photo 12).

After everything is fixed, we can start the engine and start adjusting the ignition "by ear". But if you have a stroboscope, you can use it))). To do this, with the engine running, slowly turn the distributor (the lock nut, we did not tighten it for this) "back and forth" (photo 13) and look for the middle position in which the engine speed will be the highest and evenest.

As practice shows, most owners domestic cars repair their "swallows" with their own hands. That's why most of possible problems that can occur when the engines are running are known to car owners. In this article, we will talk about what the ignition of a VAZ 2106 car is - how to correctly set the contactless ignition and what malfunctions are typical for it.

Scheme

The ignition circuit on a six-wheel engine includes the following components:

1. The distribution unit itself.
2. Candles.
3. The so-called screen.
4. Non-contact regulator.
5. Coil.
6. Generating device.
7. Ignition switch.
8. Switching device.

Possible malfunctions

VAZ electronic ignition cannot work correctly forever.

Sooner or later, malfunctions appear in the system:

• break in the wiring between the switchgear and the switch;
• breakage of the contactless regulator;
• a break in the wiring between the switching unit and the switch or directly by the coil;
• failure of the switch;
• breakdown of the ignition switch;
• poor contact or oxidation of high voltage cable lugs;
• failure or freezing of the contact coal in the cover of the switchgear;
• stress leakage through cracks or other damage to the distributor, and carbon deposits and moisture that accumulate on inside covers;
• failure of the resistor in the distributor rotor;
• breakage of the coil itself;
• failure of spark plugs due to wear or mechanical stress;
• failure of the distributor as a whole can be facilitated by incorrect connection high-voltage wires;
• improper operation of the engine may be due to too large a gap between the electrodes of the spark plugs;
• weakening of the springs of the weights of the regulatory advance device (video author - Evgeny Aleksandrovich channel).

Installation instructions

So, if you need to set electronic ignition on the VAZ 2106 to ensure the normal operation of the cylinders and the engine as a whole, we are ready to help you with this.

The procedure for setting contactless ignition (BSZ) is as follows:

1. First, the battery is disconnected from the on-board network, after which the cover of the switchgear with high-voltage cables is dismantled. One of the high-voltage devices must be disconnected from the coil.
2. With the help of short-term switching on of the starter device, it is necessary to set the distributor slider in a position perpendicular to the power unit. The contactless ignition circuit, or rather, its adjustment, implies exactly this arrangement of the device.
3. Having done this, you need to set a mark for the location of the distributor on the motor itself. Use a marker to make a mark. Next, it is necessary to unscrew the nut that fixes the interrupter unit itself; this will require a 13 spanner. Having done this, you can disconnect the cable that connects the unit to the coil, this must be done before dismantling.
4. A new breaker is being installed in the system in place of the old one.
5. Further, the body of the assembly must be rotated so that the middle mark on its body is aligned with the established mark on the engine that you applied earlier. After that, you can tighten the fixing nut of the new distributor and put the cover on it. After the cover is installed, the high-voltage cables are connected.
6. Replace the coil with a new one for normal operation new system make the best use of the new coil.
7. Next, connect all necessary wiring to this component. For correct connection you may need a VAZ 2106 electronic ignition circuit. The final stage will be the installation of the switch, it can be put in any convenient place. With the help of a strap, it is necessary to drill the appropriate holes and, using self-tapping screws, fix the device.

How to set the ignition?

After the dual-circuit ignition on the VAZ 2106 has been installed, for normal engine operation, it must be properly configured. Without this, the motor will work intermittently, causing inconvenience to the car owner.

How to set the ignition timing correctly:

1. First you need to unscrew the spark plug of the first cylinder, for this you need a spark plug wrench, and then you need to close the hole with your finger or a rubber stopper.
2. Using a special key, you need to scroll crankshaft until the piston begins to move upward - at this time, a compression stroke occurs in the cylinder. You can learn about the compression stroke by how the plug will shoot out of the plug hole. If you cover the hole with your finger, you can feel how it is being squeezed out. The crankshaft must be turned until the risk on its pulley is aligned with the risk on the timing cover. If vehicle is operated on 92 or 95 fuel, the shaft must be aligned with the middle mark. If the gasoline is of lower quality, then it must be combined with the longest mark.
3. Next, you need to disconnect the clips, and then dismantle the distributor cover. After you have cranked the crankshaft, the distributor rotor should turn independently to a certain position. With it, the external contact will be directed towards the first cylinder on the distributor cover. After all the marks are aligned, you need to pay attention to the knot itself - try drawing a visual line through the lid latches. This line, ideally, should go along the axis of the power unit, if this is not the case, then adjust further.
4. Unscrew the nut that secures the distributor, after which the assembly itself must be turned up. By rotating the rotor axis, it must be placed parallel to the motor axis. Extend the distributor and tighten the fixing nut, just not completely. Only after completing all these actions, the adjustment itself begins, for which we will use a control lamp.
5. The light bulb is connected as follows: one wiring from it must go to the output of the coil, which, in turn, is connected to the distributor cable. As for the second wire, it must be connected to ground, that is, to the engine body or the power unit housing.
6. Turn on the ignition and turn the distributor clockwise, do it slowly so as not to miss the moment until the control stops burning. If the light does not light up initially, then there is no need for adjustment.
7. After these steps, turn the distributor counterclockwise. When the light starts to light up, the distributor should be fixed in this position. The assembly retaining nut will need to be tightened all the way. After completing these steps, the ignition must be turned off, and the junction box cover must be reinstalled.

An alternative to ignition in the "six" on the contacts - contactless ignition VAZ 2106 began its march and became widespread in this lineup on vehicles going for export. And only later the share of such cars in mass production began to increase. Many car enthusiasts voluntarily go to self-installation contactless ignition and do not regret it in the future.

Having mounted a contactless ignition system, which you can buy in a specialized car store at the Volzhsky Automobile Plant, you can easily see the advantages of this complex.

Advantages of a non-contact ignition system

The main advantages of such a complex as a contactless ignition system are as follows:

1. Increased spark power due to the increased voltage potential difference in the secondary current circuit with a value of 22-24 kV (in the contact system - 16-18 kV.
2. An increased degree of combustion of the fuel-air mixture and a decrease in the concentration of carbon monoxide in the exhaust gases of the vehicle.
3. Improved start power plant at negative temperature values.
4. Significantly improved vehicle dynamics
5. A noticeable increase in reliability during the operation of a vehicle and the lack of the need for control over the functionality of the operation of such a complex.

Contactless ignition system device

A schematic diagram of the contactless ignition of the VAZ of the sixth model is located below.

1. Sensor of the contactless ignition distributor.

3. Shielded protection.

4. Non-contact type sensor.

6. Generating element.

7. Switch off component of the ignition.

9. TK - transistor equipment with a switching circuit (transistor switch).

In such a complex, a contactless ignition distributor is used to disconnect the low-voltage circuit, which works to open and close the electrical circuit, "locking" or "opening" the output transistor. Such a system allows you to increase the voltage at the electrodes of the spark plugs and, thereby, increase the energy of the spark discharge. At the same time, the voltage indicator on the spark plug elements does not decrease at low values ​​of the crankshaft rotation of the power plant, which makes the starting value of the motor much better.

Such contactless ignition, the price of which is quite high, has significant advantages over the contact system.

Contactless ignition malfunctions

Meet following malfunctions contactless ignition VAZ 2106, which are summarized in the table below.

The cause of the defect

How to fix

To install a contactless ignition, you will need a set of locksmith tools and new parts in case of replacement. You can directly watch the installation of contactless ignition on the video on the Internet. Replacement and installation of contactless ignition is carried out already on a serviceable fuel equipment vehicle.

Scheduled adjustment of contactless ignition is carried out after 30-40 thousand km. mileage. Correct setting of the non-contact ignition of a car assumes that the engine operates in an optimal mode while observing the required voltage and current values.

Experienced car owners of the popular VAZ 2106 model repeatedly encounter problems with the contact ignition system of a classic engine:

• burning of contacts, violation of the contact zone;
• changing the size of the breaker gap, respectively, the ignition angle, spark quality, idle speed;
• a decrease in the coefficient of elasticity of the interrupter spring over time, natural wear and tear, requiring replacement of the element;
• high mechanical load on the distributor support bearings, cam wear, leading to repair and periodic replacement of units.

Repair, maintenance, installation and dismantling of the distributor require skills not only mechanical work, but also knowledge in the field of auto electrical and engine diagnostics. Therefore, many motorists turn to specialized service stations to solve problems associated with servicing the contact ignition system. Rather than offering discounts to respected older car owners, some garages are pushing up prices.

A sure way to reduce the problems associated with servicing the VAZ 2106 ignition system is to install a contactless ignition system on a car. Photo: media2.24aul.ru

From models 2108 on domestic vases a non-contact ignition system is installed. The indisputable advantages of a non-contact ignition system:

• ease of maintenance and repair;
• increase in the frequency of routine maintenance;
• reduction of the level of electromagnetic interference associated with the arcing of contacts;
• an increase in the service life of the ignition coil, spark plugs, distributor;
• more uniform engine operation, stabilization of the ignition angle during operation;
• fuel savings due to the optimal setting of the ignition angle;
• increased peak voltage of high-voltage pulses (24 kilovolts instead of 16, as on the contact system) contributes to the formation of a better spark;
• easy start of a car, especially in the cold season.

Air filter zero resistance - available tuning or a useless addition? The answer is in this material.

The contactless ignition system has its drawbacks:

1. The switch, like all electronic components, has a certain lifespan. It is not a fact that the device will fail after the declared uptime (usually three years). Most switches have been in good working order for five years or more. But there are cases when the switch burns out within a month after installation. This often happens with eastern counterparts.
2. The electronic unit of the switch is non-separable, it cannot be repaired, only a unit replacement is required. Therefore, when going on a long journey, especially to sparsely populated areas, it is not superfluous to take a spare switch and ignition coil on the road.
3. Electronic devices more sensitive to voltage drops (with incorrect generator operation), electromagnetic influences. On military equipment contactless ignition is rarely used. In the event of a nuclear explosion, an electromagnetic pulse destroys all working electronics.
4. The purchase and installation of a contactless ignition system requires certain costs.

The cost of a set for a VAZ 2106 is about 2500 rubles. The installation of the system at the service station costs approximately the same amount. It is also necessary to change the spark plugs. Photo: images.ua.prom.st

In the contact system, a cam mechanism is used to synchronize the ignition angle, which drives a contact, which, opening-closing, generates electrical impulses in the primary winding of the ignition coil. On the secondary winding of the coil, high-voltage pulses are generated, coming through the distributor to high voltage wires corresponding candles.

The non-contact system replaces all elements associated with contact action.

Therefore, an electronic switch is used to amplify the pulses, otherwise a pulse amplifier. At its output there is a powerful transistor that controls the operation of the electronic ignition coil.

You need to know that the ignition coil for a contactless system differs in electrical parameters from a contact one. Therefore, the BSZ kit usually includes an electronic coil. Also, when replacing the ignition system with a contactless ignition, replace the spark plugs.

Complete set of contactless ignition system

V standard equipment contactless ignition system for VAZ 2106 includes the following components:

distributor with built-in Hall sensor, vacuum ignition timing controller and interference suppression capacitor;

• switch;
• ignition coil;
• set of wires;
• a set of candles;
• installation and operating instructions.

(BSZ) for owners of classic VAZ models is a kind of improvement of the car. Such devices are more reliable and practical. But in order to install the contactless ignition of the VAZ 2106, certain nuances must be taken into account.

[Hide]

BSZ device

The VAZ 2106 contactless ignition system consists of the following structural components:

1. The main device is a distributor or distribution unit. Inside this element is a photoelectric Hall controller and a vacuum actuator designed to change the lead angle. The distribution unit also includes a slider equipped with a movable contact element.
2. A coil designed to generate a high voltage signal. This element is equipped with two windings - primary and secondary. The first consists of a small number of turns of a thickened cable, and the second of a thin conductor, but the number of turns is greater.
3. Electronic module. It is a switching device equipped with an aluminum radiator for cooling the system. It is also used as a fastener.
4. Spark plug. They are mounted on the cylinder block and connected to the switchgear by means of high voltage cables.
5. The wire itself, which connects structural elements to each other.

The first contact of the coil is connected to the generator set via the ignition switch relay. Its second component goes to the electronic module. A high-voltage cable with a large cross-section is brought out from the coil to the distribution mechanism. Two bundles of conductors come out of the distributor, which connect it to the switching unit and spark plugs.

Principle of operation

The BSZ system on the VAZ 2106 model will operate according to the following algorithm:

1. After activating the ignition by turning the key, a 12-volt voltage is supplied to the primary winding. This leads to the formation of an electromagnetic field in the device.
2. As a result of the rotation of the crankshaft, one of the pistons of the power unit moves to the top dead center position. This causes the Hall effect sensor to send a signal to the commutator mechanism. The latter breaks the contact between the coil and the voltage source. It can be used as a battery or a generator unit.
3. When an electrical break occurs in the secondary winding, this leads to a signal with a voltage of 20 to 24 kV. This impulse is transmitted through the high-voltage cable to the camshaft slider.
4. The moving contact of the distributor provides a signal to the corresponding spark plug where the piston is at top dead center. A strong spark is formed between the contact elements, which ignites a combustible mixture of fuel and air in the internal combustion engine.
5. The timing pulley begins to move as a result of the action of the gear transmission, which is connected to the crankshaft. When the other piston moves to the top dead center position, the shaft rotates. This leads to the connection of the movable contact element with another spark plug. The Hall controller sends the next pulse, which repeats the spark cycle.

In conventional systems, the control gear did not include a Hall controller. Instead of it, a contact component was installed, the switching node was also absent. The procedure for breaking the electrical circuit was carried out by mechanics; for this, a cam on the distributor shaft was used. This element pressed on the contact component of the BSZ.

Alexey Romanov spoke about the features of the BSZ and compared contact systems with contactless.

How to choose contactless ignition on a VAZ 2106?

As a result of the fact that VAZ 2106 cars were equipped with various engines, the BSZ system must be installed taking into account the design of the distributor. For power units in volumes of 1.3 and 1.5-1.6 liters, different distributors are bought. In 1.3-liter internal combustion engines, a unit with a shortened shaft is installed, and in other engines the pulley has the same length.

The complete set of the BSZ system includes:

1. Distribution unit. Its catalog number is 38.3706-01 for a 1.3 liter engine. For power units designed for 1.5 and 1.6 liters - marking 38.37061.
2. High voltage coil. Her catalog number is 27.3705.
3. System control module. Catalog number 36.3734 or 3620.3734.
4. Set of connecting cables.

Switchgears for the VAZ 2106 and Niva VAZ 2121 models are outwardly similar, but they are different and are not interchangeable. "Nivovskie" mechanisms have different technical parameters and do not have such markings. If we talk about manufacturers, then with positive side products from SOATE have proven themselves.

For proper operation of BSZ, new spark plugs are required - A-17DVR, they are not included in the package and are purchased separately. For more efficient operation, it is recommended to install new high-voltage cables, especially if they have not been changed for a long time.

Channel " ICE theory»Spoke in detail about the work of BSZ and the peculiarities of choosing a system for classic models.

Preparation for replacing BSZ

To repair a faulty ignition system with your own hands or replace it with a more advanced one, you will not need specialized tools. It is more convenient to carry out work in the garage, but the use of the pit is not necessary. You can simply change the node on the street, the main thing is that the lighting is of high quality.

Instruments

Before completing the task, the following tool is prepared:

• open-end wrench for 13, will be used to dismantle the nuts securing the distributor mount;
• wrenches for 10 and 8 are required to remove the coil;
• two screwdrivers - with flat and Phillips tips;
• pliers;
• electric drill or hand tool;
• drills, the dimensions of which must correspond to the diameters of the self-tapping screws used to fix the switching device.

It is more convenient to perform the repair procedure for BSZ on a VAZ 2106 using a spanner wrench equipped with a long handle. It will slide over the ratchet nut and be used to rotate the crankshaft by hand.

Preliminary work

Before removing and installing the contactless ignition, preparatory work is performed:

1. The car's engine compartment opens. All actions related to the replacement must be carried out with a de-energized on-board network. This will prevent short circuits and prevent electrical equipment failure. Therefore, the negative terminal is disconnected from the battery terminal.
2. Disconnect high voltage cables from spark plugs. After disconnection, visual diagnostics of their contacts is performed. If they are damaged, then it is better to replace the wires immediately. The other ends of the cables are disconnected from the junction box.
3. The spark plugs are unscrewed, a special key is used for this.
4. Then the screwdriver is lowered into the spark plug hole of the first cylinder. The crankshaft turns until the piston rises to top dead center. The mark on it should stand opposite the long mark, which is located on the cylinder block.

If the ratchet nut wrench is not available, the crankshaft rotation procedure is performed by turning the rear wheel of the machine. It must first be hung out by placing the car on a jack. When performing this task, the vehicle must be secured with wheel chocks. Wheel spin lever parking brake goes down and the fourth or fifth gear is activated.

The channel "VAZ 2101-2107 REPAIR AND MAINTENANCE" spoke about the peculiarities of preparing classic VAZs for replacing the ignition system.

Dismantling the old system

The procedure for removing all elements of the ignition system is performed after matching the marks and preparing new parts:

1. The high-voltage conductor that comes from the coil is disconnected. The cover of the distribution unit is dismantled, after which it is imperative to remember the position of the slider. To make it easier to act, it is recommended to mark the direction with a marker or chalk on the valve cover of the power unit.
2. The cable and the vacuum pipe are disconnected from the distributor, we are talking about a hose that is connected to the carburetor device. Using a 13 wrench, unscrew the nut that secures the assembly. The mechanism is being dismantled from the engine block. There is a sealing rubber between the distribution unit and the place of its installation, it cannot be lost when removing the device.
3. Using a wrench, the nuts fixing the high-voltage coil are unscrewed, the cables are disconnected. When performing this task, you need to remember where the veins were installed, connected to the relay of the ignition switch and tachometer.
4. The coil is removed, this unit is retracted to the side.

User Sergey Avtocar 2nd CH spoke in detail about the procedure for dismantling spark plugs from engines of classic VAZ models.

Installation of a contactless ignition system

It is necessary to install and connect the BSZ after removing the non-working system:

1. First, the gasket is installed from the old switchgear to the new one, the cover is removed from it. The slider in the distributor is rotated so that it is directed towards the mark. The camshaft is installed in a socket and secured with a nut. It is not necessary to tighten it to the end, since it will be necessary to regulate the operation of the system and again loosen the nut.
2. The spark plugs are being installed. Before installing these elements, it is recommended to set the gap between the electrodes on them, it is 0.8-0.9 mm.
3. The cover of the switchgear assembly is being installed, high-voltage cables are connected. When performing this task, it is necessary to take into account the cylinder numbers, they are marked on the top of the coil.
4. Instead of the old device, a new one is fixed. If the contact elements on the coil are installed in the opposite direction, then before performing the task, the locking clamp is loosened. Then the body of the device is rotated 180 degrees. The coil is mounted on the machine.
5. A switching device is installed next to the short circuit. To do this, dismantle the expansion tank with liquid for washing. windshield... With the help of a drill, two holes are drilled in the side member of the car body, the module is fixed with self-tapping screws. The electronic component itself must not be installed below the fluid reservoir. Otherwise, if it is damaged and water leaks, the device may flood, this will lead to its inoperability.
6. The connecting cables are connected to the control unit, switchgear and coil. For connection, a circuit is used that is included in the package of the contactless ignition system. The block from the switching mechanism must be connected to the connector on the distributor. And the conductors are connected to the contact elements marked "B" and "K" located on the high-voltage coil. When making the connection, you must take into account the cores that were attached to the old coil, they must be fixed on the new device in the same way.
7. A vacuum tube is fixed on the fitting of the diaphragm element of the switchgear, which is connected to the carburetor device. The installation procedure is now complete.

In later versions of "sixes" on the body there are holes for fixing the switching device. They are located on the side member on the left, if you look in the direction of the car.

Starting the engine and adjusting the ignition

When it was possible to install and connect the BSZ, it may be necessary to adjust the operation of the system. If, when installing contactless ignition on a VAZ 2106, the marks did not go astray and the wires were connected correctly, then the engine will start immediately. After starting the power unit, the engine should warm up, this will take a few minutes, you can help with the gas pedal. Then you need to adjust the ignition.

The adjustment procedure can be performed in several ways:

• by ear - this option is less accurate, but it will allow you to correctly configure the system;
• using a stroboscope.

If the power unit does not start, and when you turn the starter device, no action occurs, you need to make sure that the "high voltage" is connected correctly. The problem may be turning the switchgear cover when installing the system. If this happens, the slider will send a pulse signal to the fourth cylinder instead of the first. The cover must be scrolled back and check that the wires are connected correctly.

The procedure for adjusting the advance angle is performed by turning the distributor body, the procedure is as follows:

1. On a running power unit, loosen the nut that secures the timing case.
2. Slowly scrolls the device clockwise and counterclockwise. You need to focus on hearing. It is important that the engine of the machine begins to run as steadily as possible. The scrolling angle should be no more than fifteen degrees.
3. When the power unit operates stably and does not triple, the switchgear nut is tightened to the end.

Channel "Ato! moto-life ”spoke in detail about the adjustment of the lead angle on the contactless SZ.

The device is connected to the clamps battery and the high-voltage cable of the cylinder numbered 1. Then the power unit starts up, and the strobe indicator light is carefully brought to the marks installed on the block. The device will allow you to determine the location of the risks that are on the pulley when the engine is running. Using a wrench, the nut of the switchgear is loosened and the unit is turned. It is necessary to ensure that this mark is aligned with the last, shortest.

When the setup procedure is completed, the power unit of the car warms up, you need to test the work done by driving in different modes. If, as a result of pressing the gas from engine compartment a metallic ringing is heard, then there is a detonation in the engine. This is because the ignition timing is too early. To adjust the distributor nut, loosen and turn the device clockwise a few degrees. There should be no detonation.

On a VAZ 2106, after replacing the ignition system, the idle speed of the power unit may increase as a result of improved spark formation. To reduce this parameter to the optimum (about 900 per minute), you need to twist the fuel volume bolt. On carburetor devices "Ozone" this element has big sizes and is located with right side, below the internal combustion engine. If a Solex unit is installed in the machine, then a plastic lever installed at the back is used for adjustment, it rests against the damper axis.

Do-it-yourself car repair channel spoke in detail about the implementation of the BSZ adjustment procedure on VAZ cars.

Malfunctions of the contactless ignition system

A detailed list of the causes of problems and repair options is given in the table.

Channel "Maysternya TV" showed the procedure for repairing a contactless distributor in garage conditions.

Pros and cons of installing BSZ

The main advantages of BSZ for VAZ 2106:

1. Ease of repair and maintenance compared to contact systems.
2. The service life of the constituent parts is much higher.
3. Reducing the magnitude of electromagnetic interference, which is associated with the formation of a spark on the contact elements.
4. The ability to provide a more even operation of the power unit. BSZ allows you to stabilize the lead angle while driving. This contributes to better fuel economy.
5. Increased spark power due to increased peak voltage of high voltage signals. This is due to the increased potential difference in the secondary current circuit.
6. Simplified starting of the power unit at low temperatures.
7. Improving the dynamic performance of the vehicle.
8. The combustible mixture in the engine cylinders burns better. This helps to reduce the concentration of carbon monoxide.

In accordance with the reviews, the following disadvantages of 2106 can be distinguished:

1. High price. Price complete set will be at least two thousand rubles.
2. Weak Hall controller. This sensor often fails at BSZ. It is recommended that you carry one spare controller with you in case a problem occurs on the road.
3. The switch node has a resource of use, but in fact the service life may be less than the declared one. In practice, such mechanisms usually work for five years or more. But sometimes premature breakdown of the device is possible, even several months after installation. This problem is typical for Asian-made mechanisms.
4. The BSZ control unit is non-separable, so it cannot be repaired in the event of a breakdown, only it can be replaced.
5. The electronic components of the BSZ are characterized by high sensitivity to voltage surges if the generator unit in the car works intermittently. Failure of elements as a result of electromagnetic influence is also possible.

Video "Real feedback from the consumer on the use of BSZ"

Channel "VAZ 2101-2107 REPAIR AND MAINTENANCE" presented real review from a car owner who installed a contactless ignition system on classic vaz.

Correctly exposed ignition is the key to the proper functioning of the engine and its quick start. Also, the ignition moment affects the amount of fuel consumed and dynamic characteristics cars, improperly adjusted ignition can cause detonation, leading to serious consequences and engine damage. The question of how to set the ignition on a VAZ 2106, each car owner decides in his own way, someone does everything "by intuition", someone uses a stroboscope, including those who resort to the help of auto repair shops. All this is not important, the main thing is to get the result, but how you did it is not so important.

The contactless ignition kit is assembled on semiconductor elements. In this scheme, the opening and closing of the low voltage circuit is carried out by unlocking or locking the output transistor using an electronic switch.

Adjusting the ignition of the VAZ 2106 is one of the most important operations, like everything related to the engine in general. Electronic system ignition means that not a mechanic will work in a car, but a photocell or optics. It is a well-known fact that mechanics breaks down and deforms over time, and optics are more reliable in these indicators. Let's say you just need to install the contactless ignition system, set everything correctly and no longer remember the many difficulties associated with working with mechanical elements. For example, you no longer have to worry about adjusting contact clearances and maintaining this system.

Any car owner can install BSZ without any special knowledge and skills. The electronic system significantly increases the performance of the engine, because in this case, the most accurate opening of the circuit and the creation of a powerful spark occurs, which favorably affects the start of the engine in the frost season. This ignition scheme also increases the voltage across 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 the specialists of auto repair shops. This is not bad, but every car owner can learn how to correctly set the ignition. Why do you need to do this at least a couple of times on your own car.

The timing cover has 3 marks - long, medium and short. They play an important role for the implementation of this adjustment scheme. Long means a lead angle - 0 degrees, medium - 5 degrees, short - 10 degrees. In addition to these marks, there is also TDC - the highest point of the piston stroke in its cylinder.

Non-contact ignition control circuit

The BSZ circuit includes a distributor sensor, a switch, ignition coils, an ignition switch and spark plugs, low and high voltage wires.

1. 1. Remove the previous high-voltage wires together with the cover of the breaker-distributor;
2. 2. Using the starter, set the slider to the top dead center of the 1st cylinder;
3. 3. When changing the coil, check how the terminals are located;
4. 4. Install the high-voltage wire from the coil into the breaker-distributor, connect the rest of the wires to the coil. In addition, green and brown wires are connected to it, which are left over from the old breaker. Terminal "B" - blue with a strip and green, terminal "L" - purple and brown.
5. 5. Install the new breaker-distributor in place, at the same time return the slider to its original form;
6. 6. Align the marks on the block of cylinders with the breaker-distributor.
7. 7. Unscrew the old plugs and install new ones;
8. 8. Install the cover on the distributor breaker and connect the high voltage wires, taking into account the circuit of the functioning of the cylinders;
9. 9. Connect the wires to the candles;
10. 10. Connect the central wire from the coil to the cover of the breaker-distributor.

Disassembly of parts

To remove the distributor cover, you just need to 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 still come in handy.

The main stages of adjusting the ignition system

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

How is the control carried out

Start moving the car, accelerate to 45 km / h, change to fourth gear and press the accelerator pedal sharply. Observe in what period the detonation is carried out in the form of the ringing of "fingers", pops and other signs that are characteristic of your VAZ 2106 car. When accelerating, these sounds should stop. If this does not happen, therefore, the ignition system of your VAZ car is "early". This can be changed by turning the valve clockwise approximately half a division.

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 was 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 as 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.

Coil working as part 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 impulses of 22-24 thousand volts. The predecessor gave out 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 reliably 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 that pivots 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 rod. 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 two elements, the device is inactive, but as soon as a gap opens in the gap, the sensor generates D.C.... 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 spar (in the direction of the car), next to expansion tank coolant.

Main functional details electronic circuit- powerful transistor and 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 elements of the system 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 terminal marked "K" is connected to the contact "1" of the controller, the tachometer wire also comes here. Terminals "3", "5" and "6" of the commutator are used to connect the Hall sensor.

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

1. 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.
2. The starter motor rotates 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.
3. The controller, by means of a transistor, opens the circuit of the primary winding of the coil. Then, in the secondary, a short-term pulse of up to 24 thousand volts is formed, going along the cable to the central electrode of the distributor cover.
4. 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, fuel mixture ignites and pushes the piston down. The engine starts.
5. When the next piston reaches TDC, the cycle repeats, only the spark is transferred to the other spark plug.

For optimal combustion of fuel 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 ahead of 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 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 frequently and are easier to diagnose. Signs of a system malfunction:

• complete failure - the engine stalls and will no longer start;
• uneven idling, shots into the carburetor at hard pressing gas pedals;
• interruptions and skipping cycles while driving.

Most often, the first symptom is the failure of the engine, 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, it is necessary 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 there is a delay 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;
• drill with a drill 4 mm (for fastening 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 will come in handy 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 old system- main valve and coil:

1. Pull the high-voltage wires out of the distributor cover sockets and disconnect it from the case by unlocking the latches.
2. 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.
3. Unscrew the clamps of the old coil and disconnect the wires. It is advisable to remember or sketch the pinout.
4. 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:

1. 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.
2. Put on the cover, locking the latches. Connect the spark plug cables according to the numbering (the numbers are indicated on the cover).
3. Screw the coil of the contactless system to the body of the VAZ 2106. So that the terminals "B" and "K" are in starting position, first unfold the product body inside the fastening clamp.
4. Put on the contacts the wires from the ignition switch and the tachometer according to the diagram above.
5. Install the controller next to the side member by drilling 2 holes. For convenience, remove the expansion tank.
6. Connect the 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. Get the most stable work motor 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, the moment of sparking will have to be adjusted again:

1. Remove the spark plug of the first cylinder and discard the main distributor cap.
2. Insert into candle well a long screwdriver and turn the crankshaft by the ratchet clockwise with a wrench (when 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.
3. 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.
4. Tighten the distributor 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 according to a light bulb connected to the ground of the car and the low-voltage winding of the coil. The ignition timing is determined by the flash of the lamp when the Hall sensor is triggered and the switch transistor opens the circuit.

Accidentally finding yourself in the wholesale market car parts, I purchased an inexpensive strobe. This device greatly simplifies the ignition setting, showing the position of the notch of the pulley 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 ignition plugs

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

• recommended by the manufacturer original candles- A17DVR (M);
• 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 denotes 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 probe. 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 significantly improves performance characteristics carburetor "Zhiguli" equipped 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.
