A method for controlling a piezoelectric actuator of a fuel injector of an internal combustion engine of a vehicle, the actuator acting on valve elements to open or close the injector, respectively enabling or stopping the injection of fuel into a combustion chamber of the engine, includes the steps of: the method applied from an on-board engine control unit during operation, and including applying to the actuator between these 2 steps at least one second electric charge to polarize the actuator during an opening phase of the injector and during fuel injection.

Method for controlling at least one piezoelectric actuator of a fuel injector of an internal combustion engine

A method for repolarizing a piezoelectric actuator associated with an injector mounted on an internal combustion engine of a vehicle, the piezoelectric actuator having undergone initial polarization before the vehicle was used, includes with the engine stopped:

Method and device for repolarizing a piezoelectric actuator of an injector of an internal combustion engine of a used vehicle

Method for controlling a piezoelectric actuator acting on valve elements to open or close a fuel injector respectively allowing or preventing fuel injection into a combustion chamber of an engine, the method includes:

Method for current-controlling at least one piezoelectric actuator of a fuel injector of an internal combustion engine
