摘要： A fuel injector with a direct needle control for an internal combustion engine, having an actuator, a hydraulic booster, and a nozzle needle guided in a nozzle body and acting on a nozzle needle sealing seat. The hydraulic booster includes a booster piston connected to the actuator and a nozzle needle booster piston connected to the nozzle needle; a booster chamber in the form of an actuator coupler chamber is associated with a pressure surface of the actuator booster piston; and depending on the pressure in the actuator coupler chamber, the nozzle needle is lifted away from the nozzle needle sealing seat, thus initiating an injection. In addition to the actuator booster piston, a control element is provided that is able to execute a stroke motion, is hydraulically coupled to the actuator coupler chamber by means of a first control surface, and is associated with a control chamber by means of a second control surface. The actuator booster piston has a second pressure surface, which, as an additional control surface, is associated with the control chamber.

摘要： A fuel injection system for internal combustion engines, having a high-pressure accumulation chamber, which contains high-pressure fuel, and at least one fuel injection valve, which is connected to the high-pressure accumulation chamber. The fuel injection valve can inject the highly pressurized fuel through injection openings into a combustion chamber of the engine. The fuel injection valve has a control chamber, which is defined by a longitudinally mobile piston and is operationally connected to the fuel injection valve so that the injection cross section of the fuel injection valve is controlled as a function of the hydraulic pressure in the control chamber. A low-pressure accumulation chamber is provided, which can be connected to the control chamber, in which a predetermined fuel pressure is maintained in the low-pressure accumulation chamber that is lower than the pressure in the high-pressure accumulation chamber.

摘要： 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.

摘要： A fuel injection valve for internal combustion engines includes a valve body (1) in which a bore (5) is defined in one end, in which a first row of injection openings (20) and a second row of injection openings (22) are formed. In the bore (5), an outer valve needle (8) cooperates with the valve seat (18) for controlling the first row of injection openings (20); between the outer valve needle (8) and the wall of the bore (5), a pressure chamber (14) is formed. In the outer valve needle (8), an inner bore (11) is formed, in which an inner valve needle (10) is located and which cooperates with the valve seat (18) for controlling the second row of injection openings (22). A pressure shoulder (30) is formed on the inner valve needle. A hydraulic opening force is exerted on the inner valve needle (10); by its opening stroke, the outer valve needle (8) opens a throttle connection (32) from the pressure chamber (14) to the pressure shoulder (30) of the inner valve needle (10).
