摘要： In a fuel injection system for an internal combustion engine with a high pressure pump for supplying pressurized fuel to fuel injection valves and a multi-way valve disposed in the high pressure fuel line to the fuel injector for controlling the fuel flow to the injector, the multi-way valve is a spool valve which includes an actuator for positioning the spool to provide selectively a flow connection between the high pressure pump and the injection valve or between the injection valve and a fuel return line and which further includes an inflow throttle structure forming a pressure control device. A pressure sensor is arranged between the spool valve and the fuel injector and supplies the sensed pressure value to a controller which compares the value with predetermined set values and provides a correction value to the multi-way valve actuator for the correction of the pressure of the fuel supplied to the fuel injection valve.

摘要： The invention relates to a fuel injector for injecting fuel into the combustion chamber of an internal combustion engine, with a nozzle needle (3). The pressure increase/pressure decrease in the control chamber (2) can be used to actuate this nozzle needle (3) in the injector body (1) between a position that unblocks injection openings and a position that closes injection openings. The leakage oil side of the control chamber (2) can be acted on via a pressure relief line (6) containing an outlet throttle (7) and via a high-pressure side inlet (8) with an inlet throttle (9), which simultaneously acts on a nozzle chamber (15) in the injector body (1) with pressurized fuel. The pressure change in the control chamber (2) of the injector body (1) takes place by means of a first on-off valve (21) and an additional on-off valve (27), wherein the first on-off valve (21) has an initial stroke (33) in the switching direction (32).

摘要： In a fuel injection system for an internal combustion engine, in which the fuel pumped by means of a high-pressure pump can be injected into the combustion chamber of the engine at at least two different, high fuel pressure via injectors, between the high-pressure pump and the injectors, at least one central pressure booster unit for all the injectors is provided. The pressure booster unit is triggerable in a targeted way as need, and as a result the fuel which is at the higher pressure can be better regulated in quantity, and the losses from friction can be reduced accordingly as well.
