Abstract (en)
[origin: WO2005059339A1] The invention relates to an operating method for an actuator of an injection valve of an internal combustion engine, more particularly for a piezo actuator, comprising the following steps: discharging the actuator for concluding an injection process, and detecting the actuator voltage. According to the invention, the actuator is short-circuited for discharging and the actuator voltage is detected while the actuator is in the short-circuited state.
