Method for operating internal combustion engine, involves controlling working magnetic valve such that working magnetic valve is switched and reference magnetic valve is not switched for forming differential voltage between coils

摘要

The method involves switching attitude of a set of magnetic valves (14a-14d) i.e. solenoid injection valves. A working magnetic valve (14b) is controlled such that the working magnetic valve is switched and a reference magnetic valve (14d) is not switched for forming differential voltage (24) and/or difference current between a signal against a coil (16b) of the working magnetic valve and a signal against a coil (16d) of the reference magnetic valve. Quick start of the working solenoid valve and the reference solenoid valve is cancelled simultaneously. Independent claims are also included for the following: (1) a computer program for operating a combustion engine (2) a control and regulating device for operating the combustion engine.
