    • A fuel injection system having a high-pressure fuel pump connected to a fuel injection valve for each cylinder of an internal combustion engine in which the high-pressure fuel pump has a piston defining a working chamber communicating with 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. When a control piston acts on the injection valve element, in a stroke position of the control piston in which the injection valve element is in its closed position, the pressure prevailing in the control pressure chamber acts on a greater end surface of the control piston than in a stroke position of the control piston in which the injection valve element is opened by its maximal stroke.

    • The present invention relates to an injection nozzle (1) for an internal combustion engine, in particular in a motor vehicle. A first nozzle needle (3) controls at least one first injection opening (5). A second nozzle needle (4) controls at least one second injection opening (6). A control chamber (32) is connected via a throttle line (35) to a pressure chamber (34) in which it is possible to adjust the injection pressure. A first control piston (41) cooperates with a first needle unit (17) that includes the first nozzle needle (3) and the first control surface (43) of this first control piston (41) can be acted on by the control pressure prevailing in the control chamber (32). In the closed position of the first nozzle needle (3), there is an axial play (44) between the first control piston (41) and the first needle unit (17). A second control piston (42) cooperates with a second needle unit (30) that includes the second nozzle needle (4) and can be acted on with the control pressure on a second control surface (45). In a closed position of the second nozzle needle (4), the second control piston (42) rests against the second nozzle needle (4) on the second needle unit (30). At middle to high pressures in the pressure chamber (34), both nozzle needles (3, 4) can close quickly. With a rapid pressure increase in the pressure chamber (34), the second nozzle needle (4) can open quickly and the two nozzle needles (3, 4) can close quickly. With a relatively low to middle speed pressure increase in the pressure chamber (34), the second nozzle needle (4) does not open or only opens at a higher pressure.

    • For each cylinder of the internal combustion engine, the fuel injection apparatus has a high-pressure fuel pump and a fuel injection valve connected to it. A pump piston of the high-pressure fuel pump defines a pump working chamber connected to a pressure chamber of the fuel injection valve, which has an injection valve member which controls the injection openings and which the pressure prevailing in the pressure chamber can move in an opening direction counter to a closing force. A first control valve controls a connection between the pump working chamber and a relief chamber, and a second control valve controls a connection between the relief chamber and a control pressure chamber, which is connected to the pump working chamber. A control piston, which acts on the injection valve member, has a surface area that is acted on by the pressure prevailing in the control pressure chamber and that is determined in such a way that with a closed second control valve, the force acting on the control piston when the fuel injection valve is open with a partial stroke of the injection valve member is sufficient to close the fuel injection valve, and with a maximal stroke of the injection valve member, this force is not sufficient to close the fuel injection valve.
