  • Fuel system for an internal combustion engine
    Patent number: 8251046
    Abstract: A fuel system for a diesel engine has both a low pressure pump, which extracts fuel from the fuel tank, and a high pressure pump, which is fed by the low pressure pump and supplies fuel to fuel injectors. The fuel injectors supply fuel to the engine cylinders, with a small portion of fuel routed back into the fuel system. According to an embodiment of the present disclosure, the injector return fuel is routed into a low pressure fuel line between the low and high pressure fuel pumps, with return fuel from the fuel rails returned through a fuel cooler to the fuel tank. The low pressure fuel line has a filter disposed therein and the injector return fuel is returned to the low pressure fuel line upstream of the filter.
