FUEL SYSTEM FOR AN INTERNAL COMBUSTION PISTON ENGINE AND A METHOD OF OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

A fuel system for an internal combustion piston engine includes a first fuel section and a second fuel section in which the first fuel section has a first inlet line connecting respective inlets of the injectors to a tank, and the second fuel section has a second inlet line connecting respective inlets of the injectors to a fuel tank. The second fuel section is arranged to inject the fuel into the combustion chambers for igniting the first fuel, in which first fuel section the inlet line extends from a high pressure pump to the respective injectors, and a fuel return line of the first fuel section extends from each of the injectors to the tank. The fuel return line has a pressure increasing means arranged to the fuel return line of the first fuel section between the injectors and the tank.
