The fuel injection system has one high-pressure fuel pump and one fuel injection valve for each cylinder of the engine. The fuel injection valve has a first hollow injection valve member and a second valve member guided displaceably, inside the first valve member for controlling first and second opening(s), respectively into the associated engine cylinder. The second valve member is movable by the pressure prevailing in a pressure chamber in an opening direction counter to a closing force and is acted upon at least indirectly by the pressure prevailing in a fuel-filled control chamber, which pressure is controllable as a function of operating parameters of the engine such that the second injection valve member, by means of the pressure prevailing in the control chamber, can be blocked, independently of an opening motion of the first injection valve member in a position that closes the at least one second injection opening. |
