の燃料供給装置。The fuel pressure chamber of the pressure regulating device is divided into a fuel pressure chamber and a pressure chamber by a diaphragm, and includes a fuel passage through which fuel is fed to the fuel injection valve by a fuel pump, and a relief passage through which part of the fuel in the fuel passage is relieved. At the same time, a pressure conduit for introducing intake pressure into the pressure chamber of the pressure regulator is communicated with the pressure chamber, and a spring is provided in the pressure chamber so that a valve body provided on the diaphragm biases the relief passage in the closing direction. In an engine in which the pressure difference between the fuel pressure in the fuel pressure chamber and the intake pressure in the pressure chamber is kept almost constant, the above spring is set when any one of the engine temperature, fuel temperature, and ambient temperature is higher than the set value. A fuel supply device for an engine, characterized in that it is provided with a control device that increases the load.
