Abstract
A fuel feeding system for a multi-cylinder engine, especially a large diesel engine, includes at least two high pressure pumps for feeding fuel from a fuel tank into respective pressure accumulator units, each of which defines a pressure chamber which is connected to at least two injectors. A passage interconnects the pressure chambers of the pressure accumulator units without obstruction. An auxiliary valve is attached to one of the pressure accumulator units for selectively connecting the pressure chamber of that pressure accumulator unit to the fuel tank.
