Method for operating injection valve, particularly fuel injection valve of internal combustion engine of motor vehicle, involves controlling piezoelectric actuator of injection valve for changing operational state of injection valve

摘要

The method involves controlling a piezoelectric actuator (12) of an injection valve by a controller (20) for changing an operational state of the injection valve. The injection valve is provided with an internal combustion engine, where the piezoelectric actuator is controlled in a frame of a test control. An independent claim is included for a controller for an injection valve, particularly a fuel injection valve of an internal combustion engine of a motor vehicle.
