ABSTRACT:
A common rail injection system for an internal combustion engine has at least one combustion chamber, a high pressure fuel pump for supplying fuel, a high pressure fuel accumulator connected to the high pressure fuel pump for storing fuel pinjat injection pressure in relation to the environment of the common rail injection system, an injector connected to the high pressure fuel accumulator for delivering fuel into the at least one combustion chamber, and a return line for returning fuel from the injector to the high pressure fuel pump. The fuel is pressurized by a return line pressure pdrainin relation to the environment of the common rail injection system. It is proposed that the common rail injection system has an adjusting means for adjusting the return line pressure pdrain. It is additionally proposed to use a pressure control means in the fuel leakage flow feedback system of an internal combustion engine.
