Abstract
A method for detecting the commencement of opening of the nozzle needle of an injector of an injection system. In the detection method, the coil of the solenoid injector has a voltage applied to it which is so low that the armature is moved toward the nozzle needle at such a low speed that the abutment causes a stoppage of the armature movement, without the nozzle needle being opened. In this case, the idle travel is overcome, but no injection process is initiated. The abutment of the armature against the nozzle needle is detected, in the current profile, as the commencement of opening of the nozzle needle.
