Abstract: A fuel injection system for internal combustion engines with a fuel injector that can be supplied from a high-pressure fuel source has an injection valve, with injection nozzles pointing toward the combustion chamber, and coaxial inner and outer nozzle needles assigned to the injection nozzles are triggerable as a function of pressure to open and close various injection cross sections at the injection nozzles. Each of the nozzle needless is assigned a respective damping piston, and the damping pistons are movable relative to one another and act on a damping chamber which can be made to communicate with a low-pressure return system via an outlet throttle. In addition to the damping chamber, a closing chamber is provided, to which an end face of the outer nozzle needle is exposed in the closing direction. The closing chamber can be made to communicate with the low-pressure return system as well, via a closing chamber throttle; the outlet throttle has a greater throttling action than the closing chamber throttle, so that the pressure in the closing chamber drops first, and only after a delay does the pressure in the damping chamber drop as well.

Abstract: A fuel injection apparatus for injecting fuel into the combustion chambers of an internal combustion engine includes a high pressure accumulator, a pressure booster, and a metering valve. The pressure booster includes a working chamber and a control chamber that are separated from each other by an axially movable piston. A pressure change in the control chamber produces a pressure change in a compression chamber that acts on a nozzle chamber via a fuel inlet. The nozzle chamber encampasses a nozzle needle. A nozzle spring chamber that acts on the injection valve element can be filled on the high-pressure side via a line that leads from the compression chamber and contains an inlet throttle restriction. On the outlet side, the nozzle spring chamber is connected to a chamber of the pressure booster via a line that contains an outlet throttle restriction.

Abstract: A fuel injection system has a pressure step-up unit, disposed between a pressure storage chamber and a nozzle chamber, whose pressure chamber communicates with the nozzle chamber via a pressure line. A bypass line connected to the pressure storage chamber is also provided. The bypass line communicates directly with the pressure line. The bypass line can be used for pressure injection and is disposed parallel to the pressure chamber, so that the bypass line is open regardless of the motion and position of a displaceable piston element in the pressure step-up unit. This enhances the flexibility of injection.

Abstract: A fuel injection system for internal combustion engines has at least one stroke-controlled injector. A pressure booster that has a movable piston is connected between the at least one injector and a high-pressure working medium source. The movable piston divides a primary chamber, which can be connected to the high-pressure working medium source, from a pressure chamber that communicates with the at least one injector and is filled with fuel. The pressure booster generates a first fuel system pressure in the injector, which is used for the injection. The fuel injection system has means for furnishing a further, second fuel system pressure, and these means can be used for injection without activating the pressure booster.
