摘要： A method for controlling an injector is described, where the trigger signal for the actuator is controlled as function of the amplitude and the duration. The actuator, using an hydraulic coupler, actuates a control valve which, at a low voltage, operates in a ballistic mode and opens up an opening cross-section to an inlet channel. The opening cross-section becomes smaller with increasing trigger voltage, and the fuel quantity to one injected increases. The control valve is brought from ballistic mode to nonballistic mode via the amplitude and duration of the trigger voltage. The delivery duration and the amplitude of the trigger voltage are tuned to each other so that one or several jumps may occur, during which a switch is made from one voltage value to another voltage value, and from one delivery duration to another delivery injection. A piezoelectric element is preferably used as an actuator.
