摘要： The invention relates to an arrangement for injecting fuel, which is at high pressure, into an internal combustion engine. An injector (25) encloses a pressure chamber (1), from which a high-pressure line (3) discharges into a control chamber (4) of a nozzle needle (5). Also contained in the injector (25) are two control valves (11, 12), which on the outlet side communicate with regions (9) of a lesser pressure level. One of the control valves (11, 12) that form the injection course (20) contains a pressure compensation system (34), by which the injection pressure course (20) can be varied by varying the stroke length (23) of the nozzle needle (5).

摘要： A fuel injection device having a fuel pump for each cylinder of an internal combustion engine, which fuel pump has a pump piston that is driven into a stroke motion by the engine and delimits a pump working chamber, which is supplied with fuel from a fuel tank and is connected to a fuel injection valve, which has an injection valve member that controls at least one injection opening and can be moved by the pressure generated in the pump working chamber in an opening direction counter to a closing force. A first electrically controlled control valve controls a connection of the pump working chamber to a discharge chamber, and a second electrically controlled control valve controls the pressure prevailing in a control pressure chamber of the fuel injection valve, which pressure acts on the injection valve member in the closing direction. A third electrically controlled control valve controls an additional connection of the pump working chamber to the discharge chamber; this connection contains a pressure control valve that opens toward the discharge chamber.

摘要： A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.

摘要： A high-pressure pump (1), which serves in particular as a radial or inline piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprises a cylinder head (2) and a pump assembly (6). Here, the cylinder head (2) has a cylinder bore (4) in which a pump piston (5) of the pump assembly (6) is guided. Here, the pump piston (5) delimits, in the cylinder bore (4), a pump working chamber (12). Also provided is an inlet valve (20) which is integrated into the cylinder head (2) and via which fuel can be conducted into the pump working chamber (12). Metering of the fuel conducted into the pump working chamber (12) can be achieved by actuation of the inlet valve (20). Here, full charging of the pump working chamber (12) may take place. It is however also possible for partial charging of the pump working chamber (12) to be achieved by means of suitable actuation of the inlet valve (20).

摘要： The invention relates to a control chamber (7), the pressure of which determines the strokes or positions of a nozzle needle (6), and which is assigned to a force or pressure sensor (20) in order to detect the progression of the control chamber pressure. Because the control chamber pressure significantly changes during the closing of the nozzle needle (6), the operating phases of the injector can be exactly determined from the sensor data and supplied to an engine controller.

摘要： The valve having a valve member guided displaceably in the direction of its longitudinal axis protrudes into a valve pressure chamber and has a sealing face extending transversely to axis, has a sealing face, which it cooperates with a valve seat, extending transversely to axis, for at least extensively closing off an opening, surrounded by the valve seat, from the valve pressure chamber. The sealing face is surrounded by an annular face, which when the valve member rests on the valve seat is disposed at a slight spacing from the valve seat. The valve member has a plurality of apertures, distributed over its circumference, through which the opening communicates with the valve pressure chamber when the valve member is resting on the valve seat.
