摘要： A method is disclosed for operating a high-pressure accumulator fuel injection system for an internal combustion engine of a motor vehicle which has a stop-start automatic function by way of which the internal combustion engine can be switched off and restarted afterwards independent of the intervention of the driver of the motor vehicle, the fuel being conveyed to the high-pressure accumulator as needed by means of a high-pressure pump and the pressure of the fuel being adjusted on the pressure side by means of a pressure control valve which is electrically actuated and open when de-energized. According to the method, the supply with power of the pressure control valve is adapted to the prevailing pressure in the high-pressure accumulator during a stop phase within a stop-start cycle.

摘要： A method is provided for controlling a valve having a spring, a pin, and an actuator for actuating the pin. A current having a specified current profile is applied to the actuator, starting from an initial current value at which the pin is in an initial position in which the pin allows the valve to move between open and closed positions. The current profile includes a section or several consecutive sections, wherein each section defines an initial current value and a final current value, a first time interval having a continuously falling current, and a subsequent second time interval having a continuously rising current. For each section, the final current value is less than the initial current value. After the specified current profile has been passed through, the pin is in a final position in which the pin prevents the valve from moving between open and closed positions.

摘要： A valve includes a spring having a spring force, an actuator having an actuator force that acts against the spring force, and a tappet that can be actuated by means of the actuator. The valve also includes a sealing element, which is or can be coupled to the tappet, and a sealing seat, such that the valve is closed when the sealing element lies against the sealing seat. A current having a specified curve, proceeding from an initial value of the current to a specified final value of the current, is applied during a specified time interval of the actuator after a closing phase of the valve for a normally open valve or after an opening phase for a normally closed valve. The initial value of the current is less than the final value.

摘要： A method and device are provided for detecting when a closing point of a hydraulic valve has been reached. The valve has a closing element operated by an electric actuator. A predetermined voltage for closing the valve is applied to the actuator. A profile of a current flowing through the actuator is detected. Based on a first increase in the profile corresponding to the valve being at least partially open, a subsequent decrease in the profile corresponding to the closing element carrying out a movement to close the valve, and a second increase in the profile following said decrease in the profile, a local minimum of the detected current is determined between the decrease and the second increase in the profile. Depending on the local minimum of the detected current, a closing point is then determined which corresponds to a time point of the local minimum of the detected current.
