摘要： A fuel injection system for supplying pressurised fuel to a fuel injector (200) comprises an accumulator volume (606) for supplying fuel at rail pressure (P1) to the fuel injector (200) through a rail fuel supply passage (608) and a fuel pressurising arrangement (604) for supplying fuel at a selected pressure greater than rail pressure (P2) to the fuel injector (200) through a pressurised fuel supply passage (614). A fuel shut-off valve (618) is provided in the system which is operable between a closed position in which fuel is retained within the pressurising arrangement (604) and an open position in which pressurised fuel is supplied to the injector (200) from the pressurising arrangement (604) during an injection of fuel from the rail fuel supply passage (608). Operating the shut-off valve in this way provides a boost in the fuel pressure delivered during an injection event.

摘要： A fuel injection system having a prefeed pump, through which fuel from a fuel supply container is pumped to a high-pressure pump, and by means of the high-pressure pump, fuel is pumped into a reservoir. Communicating with the reservoir is at least one injector, through which fuel is injected to the engine. A fuel filter is disposed between the prefeed pump and the high-pressure pump. A return line for uninjected fuel leads back from at least one injector into a region upstream of the high-pressure pump. A valve is provided, by which the return line, in a first switching position, at a low fuel temperature, leads to upstream of the fuel filter, between it and the prefeed pump, and by which the return line, in a second switching position, at a high fuel temperature, leads to downstream of the fuel filter, between it and the high-pressure pump.

摘要： The invention relates to a common rail injector for injecting fuel in a common rail injection system of an internal combustion engine, in particular a large diesel engine, having an injector housing which communicates with a central high-pressure reservoir and in which a nozzle needle can move axially counter to the initial stress of a nozzle spring which is contained in a nozzle spring chamber, in order to adjust the injection onset and the injection quantity as a function of the position of a 3/2-way valve. In order to improve the damping behavior in a common rail injection system, an injector pressure reservoir is integrated into the injector housing and communicates with the central high-pressure reservoir independent of the position of the 3/2-way valve.
