Title:
エンジンの燃料供給装置
Document Type and Number:
Japanese Patent JP5128784
Kind Code:
B2
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 (9) extended from a fuel tank (2) and having an injector (8) in a leading end side, a motor-driven fuel pump (3), and an electronic control unit (12) drive controlling the fuel pump (3) and the injector (8), a pressure sensor (13) detecting a fuel pressure so as to output to the electronic control unit (12) is arranged at a position near the injector (8) in the fuel supply pipe line (9) where a fuel pressure approximately coincides with a fuel injection pressure, the electronic control unit feedback controls the operation of the fuel pump (3) 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 (3) is arranged outside an engine room (50).
