Abstract: A method for controlling a valve including a spring, an actuator having an actuator force opposing the spring, and a pin actuatable by the actuator. To open the valve, in a first operating mode a current having a predefined curve is applied to the actuator, starting from a starting value of the current at which the pin is positioned to allow the valve to close, measured values of the current are determined chronologically sequentially, a reference value of the current takes on the current measured value of the current when the measured current deviates from the applied current by a predefined degree. In a second operating mode, a current having a predefined curve is applied to the actuator, starting with the starting value of the current to a final value of the current at which the pin is in a position that prevents the valve from closing.

Abstract: When a flow regulating valve is opened, the passage of current through a solenoid is stopped to move a movable part from a closing-side position to an opening-side position and to thereby open the flow regulating valve. When a sound reducing control performing condition is fulfilled, a valve-opening control for reducing sound is performed. In the valve-opening control, until a fuel pressure in a pump chamber is decreased and the flow regulating valve is opened, the passage of current through the solenoid is continuously performed to hold the movable part at the closing-side position. After the flow regulating valve is opened, the passage of current through the solenoid is stopped. Before the movable part reaches the opening-side position, the passage of current is again temporarily performed. An electromagnetic attracting force is temporarily generated and a moving speed of movable part is decreased by the attracting force.

Abstract: The invention relates to a method and a device for offsetting bounce effects in a piezo-actuated injection system of an internal combustion engine using a control valve actuated by a piezoelectric actuator. The inventive method comprises the following steps: detecting an actual bounce behavior of the control valve, and determining and offsetting a deviation between the actual bounce behavior and a desired bounce behavior of the control valve, thereby generating an actuation information for the control valve which influences a speed characteristic of a needle of the control valve. The invention also relates to a device for carrying out the inventive method.
