摘要

The method has a required fuel injection pressure for the high pressure fuel injection determined for each engine operating mode, with exact control of the fuel injection quantity via the opening of the fuel injection valve, a pump supplying a fuel quantity corresponding to the required fuel pressure to the common-rail (58) of the fuel injection device. An Independent claim for a high pressure fuel injection device is also included.
