摘要:
A device comprises: an injector for injecting fuel into an engine combustion chamber, a switch formed by an injector housing and an injector nozzle needle and which changes its switching state depending on a closed or open state of the injector, an input line for supplying energy to an actuating element which adjusts the nozzle needle in its two states, an output line for conducting energy away from the actuating element, and an evaluation unit for detecting the switching state of the switch, wherein a first switch contact of the switch is connected to an electrical input line of the injector, a second switch contact of the switch is connected to ground, and the evaluation unit is configured to carry out a signal measurement on the input line and/or an output line to conclude a switch state.
