METHOD FOR OPERATING A FUEL INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for operating a fuel injection system of an internal combustion engine. Said fuel injection system comprises a high pressure accumulator (rail) and a high-pressure fuel pump with a digital inlet valve and which guides fuel into the high pressure accumulator. The number of the control pulses for the digital inlet valve and thus the number of the pump delivery strokes is reduced with respect to the number of the injection steps of an injector of the injection system, in order to reduce, in said manner, the noise and the energy consumption.
