Ignition VAZ 2110 injector, circuit, spark plugs, ignition module VAZ-2110

Ignition VAZ 2110 injector fundamentally different from the carburetor versions. Firstly, in the ignition system of the injector “dozens”, there is no distributor on the camshaft shaft and the main ignition coil, which are typical for all carburetor machines. In injection models VAZ 2110, 2111, 2112, the ignition system is built without the use of moving elements.

A feature of the ignition of the VAZ 2110 injector is the absence of advance angle adjustments, in addition, the injector ignition of the “tens” does not require any maintenance. The main element of the whole scheme is ignition module, we look at the photo of the module at the beginning of our article. The module consists of a pair of ignition coils and electronics that controls the distribution of high energy to the spark plugs. In turn, the commands ignition module VAZ 2110 injector gives the controller. The entire ignition circuit is further in our image.

On ignition scheme of the injection engine VAZ-2110 the following elements are shown -

• 1 - battery
• 2 - ignition switch
• 3 - ignition relay
• 4 - spark plugs
• 5 - ignition module
• 6 - controller
• 7 - crankshaft position sensor
• 8 - setting disk
• A - matching device

Injector Spark Plugs on the "top ten" for an 8-valve engine and for a 16-valve engine are different in design. For 8-valve injectors, spark plugs are used A17DVRM, for 16-valve power units these are candles AU17DVRM. The latter have a more compact size and are unscrewed with a 16 key. In the 8-valve cylinder head, the candles are installed in the same way as on the carburetor versions of the engine, but in the 16-valve cylinder head, the candles are recessed vertically in the wells of the cylinder head. The normal gap between the electrodes of these candles is 1.0-1.15 mm.

Sparking in the injection motor 2110 occurs immediately in two cylinders. At the same time, in one cylinder, a spark ignites the working mixture on the compression stroke, and on the second cylinder, a spark appears on the exhaust stroke and does not affect the operation of the engine in any way, that is, this is the so-called “idle spark”. Thus, sparking occurs in pairs, which facilitates the entire scheme of operation of the power unit. To do this, the ignition module just has two high-voltage coils with a constant current direction. The spark alternately appears in 1-4 and 2-3 cylinders.

Another important element of the VAZ-2110 ignition is the controller. Exactly ignition controller gives a command to the module that it is time to direct the current to certain candles. The controller receives information from the crankshaft position sensors, the mass air flow sensor, the crankshaft speed and the presence of detonation. Even coolant temperature information is used. After processing all the information from the sensors and calculating the sequence of operation of the coils in the module, the controller sends a signal to the module, and current flows from it to the candles. Thanks to such an ignition system, the VAZ-2110 injection engine works stably and reliably.
