ABSTRACT:
For each cylinder of the internal combustion engine, the fuel injection system has one high-pressure fuel pump with a pump work chamber and one fuel injection valve communicating with the pump work chamber. A control valve actuated by means of a piezoelectric actuator control connection of the pump work chamber with a relief region. The fuel injection valve has a first injection valve member, by which at least one first injection opening is controlled and which is movable by the pressure generated in the pump work chamber in an opening direction, counter to a closing force. Inside the hollow first injection valve member, a second injection valve member is guided displaceably, by which at least one second injection opening is controlled and which is movable in an opening direction by the pressure prevailing in the pressure chamber, counter to a closing force; the second injection valve member is urged in the closing direction at least indirectly by the pressure prevailing in a fuel-filled control pressure chamber which is controlled variably as a function of engine operating conditions.
