Electronic ignition on VAZ-2106: installation, scheme, price. Adjustment of electronic ignition VAZ-2106

What can boast of an electronic ignition on the VAZ-2106, what are its drawbacks? To answer these questions, it is necessary to consider the main nodes and the operation principle of the two systems - contact and contactless (electronic). There is no sense to consider microprocessor, since it is mounted exclusively on cars with an injection fuel injection system. Unfortunately, on all sixes only the carburettor was installed. There is, of course, the possibility of installing an injector system, but it will cost a pretty penny. Of course, this is a significant improvement in the motor, but it can be slightly upgraded if changes are made to the ignition system.

The main elements of the ignition system

Now we need to consider the common elements of all ignition systems. They are the same in all, regardless of whether the electronic ignition system VAZ-2106 is installed or contact. First, candles are everywhere. They consist of a central electrode, between it and the mass there is a small gap. It is insulated from the body by a ceramic element. Rare candles live 30 thousand km. Mileage, and some even collapse. Burn out so that part of the central electrode falls into the cylinder. For this reason, it is necessary to replace them in time.

Secondly, the armored wires connecting the high-voltage parts. They consist of a special fiber, which transmits a pulse with a high voltage. Only five wires - four for connecting the distributor cover with the candles. And one - to connect the coil with the distributor. Thirdly, the ignition distributor is present in all designs, however, they have small differences. Fourthly, the ignition coil is a transformer capable of tens of times increasing the voltage entering the primary winding. But the scheme of electronic ignition VAZ-2106 is a bit more complicated than the one used in the classical system.

Contact ignition system

The oldest, oldest, morally obsolete, with many shortcomings. Only so it can be described, other words are not suitable for it. Despite all its shortcomings, it was widely used for many years, even when European cars were equipped with a microprocessor control system with fuel injection, for example, M-Jetronic and L-Jetronic. Advantage of the contact system in its simplicity. But the adjustment of electronic ignition VAZ 2106, for example, does not cause any special difficulties.

In the ignition distributor there is a central axis that moves due to the connection to the drive that rotates the oil pump. But the axis has a small cam in the upper part. It is necessary to drive the contact group. This is the central element of the system, it is with its help that a pulse is applied to the high-voltage coil, hence, a voltage of about 30 kV. But there is a drawback - the switching of a large current is carried out by the contact group. Because of this, there are eternal problems.

Contact-transistor

Slightly more perfect, but not L-Jetronic, of course, a contact-transistor system. It has one big plus, though many flaws remain from the classic ignition system. The contact breaker has not gone anywhere, it stands in its place in the distributor. In the same way is set in motion, contacts are blurred gradually, they become unfit for use. But from one harmful factor got rid of - switching low current occurs. We can say that this is almost an electronic ignition on the VAZ 2106, but there is no switch. Also, there is no burning of contacts, it is already a little easier to operate the system, its resource is increasing. Contacts control a transistor that works in a special key mode (like a switch). And all the large current is switched with it.

Non-contact system (electronic)

It remains to this system half a step to L-Jetronic, since in it even one sensor is used. This is the Hall sensor. A small device that took over the functions of a contact breaker. He has many advantages. It starts with the fact that there is no direct contact. Consequently, the resource of the system depends directly on the quality of the trampler and wires. Also, it is not superfluous to mention the fact that all weak current is controlled. This also distinguishes the electronic ignition of the VAZ 2106 from the classical scheme.

The Hall sensor produces a weak signal, which is not enough to excite the primary winding of the coil. But it is quite enough for it to be read as a special device - a switch. With its help, the signal amplifies and supplies it to the ignition coil. The advantages of the system will be told a little lower, and now it's time to talk about the difficulties that can be encountered when installing electronic ignition.

Is it difficult to make a replacement?

If you briefly answer, then you can just say one word - no. In fact, if you know how to set the ignition timing on the contact system, then there will be no problems with the electronic one. For sale electronic ignition VAZ-2106, the price of which varies in the range of 700-900 rubles, in any store. And in the complete set of delivery there is everything, that is necessary - and wires, and the switchboard, and the distributor, and even self-cutters on metal. Buy only a cue ball so that with its help these screws can be screwed.

As for the distributor, it looks similar to the one used in the contact system. With one difference - instead of a group of contacts there is a Hall sensor, and on the side surface there is a connector for inclusion in the on-board network. The drive is the same, from the oil pump, the cover of the trambler, too, the essence of the procedure for setting the angle of advance is no different from the one you use in the case of the classical system.

What advantages can you get?

But you will get many benefits if you install an electronic ignition VAZ-2106 instead of a contact one. It's better to start with the fact that any driver likes to drive more than repair a car. But frequent replacement of the contact group or its cleaning and adjustment, causes terrible hostility among motorists. Moreover, contact can fail at any moment, therefore it is necessary to have a spare with you. But the electronic system on this side is much more reliable and does not require frequent maintenance.

But the most important thing happens in the engine - in the heart of any car. His work is normalized. It starts to function correctly, regardless of the speed of the crankshaft. Although at idle, although at 4000 rpm, the engine works perfectly smoothly, stably, ignition of the fuel-air mixture occurs in a timely manner. And this improves your comfort, increases the reliability of the engine, and most importantly - increases its resource.

Installation rules and diagram

It is worth noting that the scheme of electronic ignition VAZ-2106 is very simple, it can understand a person who is far from electricians. In the kit there is a small manual, in which all the wires are drawn, their color markings are indicated. In addition, at the ends of the wires are tips and plugs, which can not be incorrectly put. The only nuance is that the whole system needs to be powered from the contact of the lock, on which there is voltage when the ignition is switched on. Otherwise, the switch and the whole system will be under constant voltage, and this is unacceptable, since the risk of a fire is high.

Conclusion

In conclusion, I would like to note that, no matter how perfect the electronic ignition on the VAZ-2106, the microprocessor system is much more effective and more promising. Therefore, thinking about how to change the car, pay attention to the injection injection. Its application will allow to achieve greater engine power, and also will add comfort when driving.
