Abstract (en)

[origin: EP2180168A2] The method involves actuating actuator by using an actuation current signal for a fuel injection. Actual actuator voltages (144,146) are determined during fuel injection (150). The control current signal is regulated, when the actual actuator voltage lies above actuator voltage threshold value (112), for another fuel injection in such a way that the actual actuator voltage approaches a reference actuator voltage (114) during another fuel injection. An independent claim is included for a control device for actuating a fuel injector for an internal combustion engine.
