7.6. Ignition system
THE GENERAL DATA

The electric scheme of direct system of ignition (DIS)

The ignition system is intended for ignition of a working mix in engine cylinders by the spark category which should be created during strictly certain moment.

On cars the direct system of ignition (DIS) is established. In this system of ignition there is no ignition distributor.

The ignition system consists of two coils of ignition. Each coil of ignition actually consists of two separate high-voltage windings which submit a spark to two cylinders everyone. The ignition impulse moves at once on two spark plugs for each cylinder of the engine, one – on the compression step, one – on an exhaust step. The ignition spark on an exhaust step does not influence engine work and consequently it is spent for nothing.

The electronic control block (ECM) uses inputs from various gauges to calculate demanded installation of a corner of an advancing of ignition and time of accumulation of energy on the ignition coil.
