機関の燃料供給装置。 A fuel distribution pipe connected to a fuel injection valve, a fuel tank, a pump housed in the fuel tank and configured to pressure-feed the fuel in the fuel tank to the fuel distribution pipe, and a pump provided near the discharge port of the pump. a pressure regulator that adjusts the fuel discharge pressure of the pump so that the fuel injection pressure of the fuel injection valve becomes a constant value, and a pressure regulator that connects the fuel distribution pipe and the fuel tank, and transfers excess fuel to the fuel tank. a control valve for opening and closing the return pipe; and means for determining whether bubbles are likely to occur in the fuel in the fuel distribution pipe;
A fuel supply device for an internal combustion engine, characterized in that a valve opens when it is determined that bubbles are likely to occur in the fuel in the fuel distribution pipe.
