Abstract:
To provide a fuel feeding device for an engine to further improve startability in cold starting and in high temperature restarting, by simplifying constitution.
A fuel return passage is connected to the fuel discharge port of a fuel pump to feed fuel in a fuel tank to a fuel injection valve through a fuel feed passage. The opening of a flow rate control valve to open and close the fuel return passage is controlled to an optimum fuel pressure by controlling a flow rate control valve by means of a pressure difference by comparing a target fuel pressure and an actual fuel pressure.
