Abstract
The invention can avoid an energy dissipation and a consumption of an apparatus by minimizing a driving amount of a fuel pump and maintain an improved fuel supply state, in a fuel supply system injecting a liquefied gas fuel by an injector and supplying to an engine. In a return-less type engine fuel supply apparatus provided with a fuel supply pipe line () extended from a fuel tank () and having an injector () in a leading end side, a motor-driven fuel pump (), and an electronic control unit () drive controlling the fuel pump () and the injector (), a pressure sensor () detecting a fuel pressure so as to output to the electronic control unit () is arranged at a position near the injector () in the fuel supply pipe line () where a fuel pressure approximately coincides with a fuel injection pressure, the electronic control unit feedback controls the operation of the fuel pump () on the basis of the detected fuel pressure in such a manner that the fuel injection pressure maintains a predetermined target pressure, and the fuel pump () is arranged outside an engine room ().
