の燃料供給装置。The fuel that is pumped through the fuel suction pipe by the fuel pump is supplied to the injector after pressure adjustment by the pressure regulator, and excess fuel that is not used for injection is sent to the fuel tank via the pressure regulator. In the fuel supply system for an engine with a fuel injection device, the fuel tank is provided with a low-temperature fuel tank for storing low-temperature fuel that is not directly affected by the temperature of the excess fuel, and the low-temperature fuel tank one end of the low-temperature fuel suction pipe is communicated with the low-temperature fuel suction pipe, and the other end of the low-temperature fuel suction pipe is connected to a switching valve that is connected in the middle of the fuel suction pipe and selectively supplies fuel from the low-temperature fuel tank to the fuel pump, A fuel supply device for an engine equipped with a fuel injection device, characterized in that the switching valve is operated to switch based on the output of a sensor that detects the fuel temperature or phase state immediately upstream of the injector.
