Repair and car operation

The system of electronic ignition includes the ignition lock, the battery, the block of electronic ignition, the sensor of the Hall (1980-87) or the induction sensor (with 1988г.), coil of ignition, wire of a low-voltage (primary) chain and high-voltage (secondary) chain, ignition and candle distributor.

On cars since 1988 management of work of system of ignition is provided or the separate processor block (ECU - the block), or the processor block of the ECM engine.

The processor block provides automatic adjustment of a corner of an advancing of ignition according to signals from sensors which trace various parameters of the engine (such as number of turns, volume of sucked-in air, temperature of cooling liquid, etc.). Such system is called as ignition system with electronic control by the moment of ignition (ESA system).

On considered cars the coil of ignition is mounted separately from the distributor.

Cars of 1980-87 are equipped centrifugal and vacuum with regulators of an advancing of ignition. The electronic switchboard of ignition is mounted on the coil case. The sensor of signals on effect of the Hall is built in the distributor on a breaker plate with which the rod of a vacuum regulator (see fig. is rigidly connected. Scheme of ignition of cars of 1980-87).

Cars of 1988-92 are equipped with automatic system of an advancing of ignition of ESA on the basis of the induction sensor (see fig. Scheme of ignition of cars of 1988-92). The electronic switchboard of ignition is mounted on the coil case.

The system of ignition of cars since 1993 is similar to system of cars of 1988-92 behind that exception that in the induction sensor the additional winding with pair of conclusions of G1 and G2 (see fig. is provided. Scheme of ignition of cars of 1993).

At performance of checks and repair of system of ignition it is necessary to observe the following safety rules (except specified above).

Connect a tachometer according to the instruction of the manufacturer. Tachometers of some types are incompatible with system of electric equipment of the car. Before acquisition of a tachometer consult in car-care center.

Do not allow a contact of conclusions of the coil of ignition with weight. Otherwise failure of the electronic block and the coil is possible.

Constantly watch that the electronic block was reliably connected to weight.
