Abstract
A method for operating a self-igniting, air-compressing internal combustion engine, in which the engine is supplied with fuel by an injection system that has a high-pressure fuel reservoir, which is supplied with fuel by a high-pressure fuel pump and outputs fuel to electrically controlled injection valves. A control unit is provided, which detects the operating mode of the engine and upon occurrence of an overrunning mode allows a pressure increase in the high-pressure fuel reservoir. On resumption of normal operation, the drive of the high-pressure fuel pump is then interrupted, and the engine is supplied from the fuel previously stored at elevated pressure, until a lower limit value of the high pressure fuel is attained.
