Abstract (en)

[origin: DE19922969A1] The method is carried out, so that a continuous matching of the control and regulating parameters at the respective operating conditions of the IC piston engine results, concerning a determination of the respective actual operating conditions of the piston engine and/or regarding performance graphs deposited in the engine conrol unit and/or concerning continuous measurements, and from these respectively the current supply so results, that the armature of the solenoid valve drive, occurs with the lowest possible speed.
