Abstract
The present disclosure relates to injection valves. The teachings thereof may be embodied in various valves, fuel injectors, and methods for controlling valves. An example method for setting operational parameters of a fuel injector may include: determining a measurement-specific maximum current value; applying a voltage pulse to the coil drive of the fuel injector; detecting a time curve of the current intensity of a current flowing through the coil drive; ending the voltage pulse when the detected current intensity reaches the maximum current value; and storing the time curve of the detected current intensity. The method may include generating a plurality of differential curves each based on two stored time curves of the detected current intensity for successive measurements; determining a peak current for driving the actuator of the fuel injector based at least in part on the plurality of differential curves; and operating the coil at the determined peak current.
