ABSTRACT:
A fuel injection system having a high-pressure fuel pump and a fuel injection valve connected to it for each cylinder of the internal combustion engine. A pump piston of the high-pressure fuel pump delimits a pump working chamber that is connected to a pressure chamber of the fuel injection valve, which has an injection valve element that controls injection openings and can be moved in an opening direction counter to a closing force by the pressure prevailing in the pressure chamber. A first control valve controls a connection of the pump working chamber to a relief chamber and a second control valve controls a connection of a control pressure chamber which communicates with the pump working chamber, to a relief chamber. A throttle restriction is respectively provided in connections of the control pressure chamber to the pump working chamber and the relief chamber. An additional pressure chamber is provided, which is connected to the pump working chamber and is delimited by a pressure surface that is used to exert an additional force on the injection valve element in the closing direction.
