초록

A fuel circuit for a fuel system including a fuel reservoir, a fuel injection system, a fuel lift pump, and a fuel filter assembly. The fuel circuit includes a fuel passageway for recirculating the excess fuel flow from the outlet of the fuel injection pump to the inlet of the fuel injection pump. The excess fuel flow, which is pressurized by the fuel injection pump, is preferentially utilized as the fuel source over fuel in the fuel reservoir, which is at a lower pressure. The fuel circuit may include a single fuel-to-air heat exchanger or a fuel-to-coo...
