GENERAL INFORMATION

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

The block of ignition 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 N1 cylinders and 4, and another – to N2 cylinders and 3). The impulse of ignition 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 a step of an exhaust does not influence operation of the engine and consequently is spent for nothing. The ECU block uses entrances from various sensors to calculate demanded installation of a corner of an advancing of ignition and time of accumulation of energy on the ignition coil.
