Abstract
A method for operating at least one injector of an internal combustion engine, in which a voltage applied to the injector is varied, and a rotational speed pattern of the internal combustion engine is ascertained as a function of the voltage, a setpoint voltage, suitable for operating the at least one injector, corresponding to that varied applied voltage for which a peak arises in a spectrum of the rotational speed pattern.
Claims10
A method for operating at least one injector of an internal combustion engine, the method comprising:
- varying a voltage that is applied to the at least one injector;
- and
- ascertaining a rotational speed pattern of the internal combustion engine as a function of the voltage;
- wherein a setpoint voltage suitable for operating the at least one injector corresponds to that varied applied voltage, for which a peak arises in a spectrum of the rotational speed pattern.
