In this control system, the injection and ignition systems are combined in one control unit. Precise adjustment of the injection quantity and ignition timing is carried out according to the signals of sensors such as. e.g. coolant temperature sensor or knock sensor. The pressure in the system, limited by a membrane pressure regulator, for KE-Motronic is 6.1-6.6 bar. The pressure required to open the injection valve is 3.7-4.8 bar. This pressure is maintained even when the engine is stopped. This prevents the formation of steam locks in the power system.
