Process for controlling the ignition point in internal combustion engines

摘要

The control operates on an energy-storage injector with an electromagnetic piston pump (11) drawing fuel from the tank (12) and accelerating it into a pressure line (14) through an electromagnetic stop valve (16). The pump has a coil (21) surrounding an armature (22) with a compression spring (24) behind the piston (26). The pump and valve are operated by a common electronic controller (9) which gives the signal for the fuel injection process. This signal is used to start the measurement of a predetermined delay time before another signal is given for the creation of the spark.
