Abstract (en)

[origin: US2008189025A1] A fuel injection device comprising a high-pressure pump supplying a fuel to a high-pressure area in which an injector for injecting fuel into an internal combustion engine cylinder is arranged. An electric control unit for controlling fuel injection by at least one injector is provided. A pressure adjusting valve which adjusts a pressure in the high-pressure area and controls a connection between said high pressure area and a low-pressure fuel-filled area is controlled by the control unit. When the pressure adjusting valve is not controlled by the control unit it is placed in an open switching position in such a way that the connection between the high- low-pressure areas is opened, thereby preventing a gas formation in the high pressure area when the internal combustion engine is switched off and the fuel is cooled.
