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.

摘要： A method for operating a valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, in which an auxiliary variable is obtained as a function of at least one electrical operating variable of an electromagnetic actuator driving a component of the valve, in particular a valve needle, and in which the auxiliary variable is checked for the presence of a predefinable characteristic. A reference variable which characterizes the operating behavior of the electromagnetic actuator is ascertained, the auxiliary variable is modified as a function of the reference variable to obtain a modified auxiliary variable, and the modified auxiliary variable is checked for the presence of the predefinable characteristic.

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.
