Patent ID: 8205596

Claim:
A fuel injection device for an internal combustion engine, comprising a delivery pump, which is equipped with an electric drive unit and delivers fuel from a fuel tank into a low-pressure region and to an intake side of at least one high-pressure pump, the high-pressure pump delivering fuel into a high-pressure region in which at least one injector is provided, which injects the fuel into the engine, and an electric control unit for controlling the fuel injection, a pressure sensor contained in the low-pressure region that is connected to the control unit, wherein the control unit triggers the electric drive unit of the delivery pump in order to adjust a delivery quantity of the delivery pump, which quantity is variable as a function of at least one operating parameter of the engine and/or of the high-pressure pump, and in order to produce a predetermined pressure in the low-pressure region, at least a part of the fuel that the delivery pump delivers into the low-pressure region is conveyed through a drive region of the high-pressure pump, and wherein the fuel injection device includes a temperature sensor, which detects the fuel temperature and is connected to the electric control unit, and the control unit triggers the drive unit of the delivery pump so that with a high fuel temperature, the delivery pump produces a higher pressure in the low-pressure region than with a low fuel temperature.
