Abstract
Various embodiments may include a method for adapting the opening behavior of a fuel injector having a solenoid drive, the method comprising: applying a voltage pulse having a predetermined electrical voltage to the solenoid drive; acquiring a time profile of the strength of a current flowing through the solenoid drive; comparing the acquired time profile with a reference profile; and adjusting a value of a mechanical parameter of the fuel injector to reduce a deviation between the acquired time profile of the strength of the current and the reference profile.
