    摘要: A method is for operating an injector, in particular a fuel injector of an internal combustion engine in a motor vehicle, the injector having a piezoelectric actuator for driving a valve needle coupled, preferably hydraulically, to the actuator. Starting from a starting voltage corresponding to a first operating state of the injector, the actuator is recharged, i.e., charged or discharged, by a predefinable voltage swing to a target voltage corresponding to a second operating state of the injector.

    摘要: A method is for operating a fuel injector, in particular of an internal combustion engine of a motor vehicle, the fuel injector including a piezoelectric actuator for driving a valve needle, which is connected, preferably hydraulically, to the actuator, and the control voltage of the piezoelectric actuator being analyzed to infer an operating state of the fuel injector. According to this method, the second time derivative of the control voltage and/or a variable depending on the second time derivative of the control voltage is/are analyzed.
