摘要： The fuel injection apparatus has one fuel pump for each cylinder of the engine, which pump has a pump piston, driven by the engine in a reciprocating motion, that defines a pump work chamber, which communicates via a line with a fuel injection valve, disposed on the engine separately from the fuel pump, which valve has an injection valve member, by which at least one injection opening is controlled, and which is movable in the opening direction, counter to a closing force, by the pressure generated in the pump work chamber, and at least one first electrically triggered control valve is provided, by which a communication of the pump work chamber with a relief chamber is controlled, and which is disposed near the fuel pump. A second electrically triggered control valve is provided, which is disposed near the fuel injection valve and by which the pressure prevailing in a control pressure chamber of the fuel injection valve is controlled, by which pressure the injection valve member is urged at least indirectly in the closing direction.

摘要： The fuel injection apparatus for internal combustion engines has one fuel pump for each cylinder of the engine, which pump has a pump piston, driven by the engine in a reciprocating motion, that defines a pump work chamber to which fuel is delivered from a fuel tank and which communicates with a fuel injection valve that has an injection valve member by which at least one injection opening is controlled and which is movable in an opening direction counter to a closing force by the pressure generated in the pump work chamber, by means of a first electrically controlled control valve, a communication of the pump work chamber with a diversion chamber is controlled, and by means of a second electrically controlled control valve, the pressure prevailing in a control pressure chamber of the fuel injection valve is controlled, by which the injection valve member is urged at least indirectly in the closing direction. The diversion chamber is a pressure reservoir, in which an elevated pressure, compared to the pressure prevailing in the fuel tank, is maintained.

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： The invention relates to a method for shaping the injection pressure course (27) in injectors, which are used for instance in injection devices of injection systems in motor vehicles. The injection device includes a pump part (1) and an injection nozzle part (2). The pump part (1) and injection nozzle part (2) communicate with one another via a high-pressure line (3).
