Abstract

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.
