THE GENERAL DATA

On all models the ignition system is united with system of injection of fuel and represents an incorporated control system of the engine from one block ECU.

The ignition block 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 (one – to cylinders N1 and 4, and another – to cylinders N2 and 3). 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 is spent for nothing. Block ECU 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.
