とする内燃機関の燃料供給装置。 A protrusion that bulges upward is provided on a part of the bottom wall, and the protrusion divides the bottom space into main and sub-bottom spaces.The fuel tank supplies fuel to the engine using a fuel pump. In the fuel supply system for an internal combustion engine configured as above, the fuel pump is configured with a concentric runner type turbine pump having a main suction port and a sub-discharge port opened in the main bottom space and a main discharge port connected to the engine, The sub-intake port of the pump and the sub-bottom space are connected via a sub-suction passage, and the pressing force due to the weight of fuel in the sub-bottom space and the suction force of the fuel pump transmitted via the sub-suction passage are used to open the valve. A valve that acts as a force is provided in the auxiliary suction passage, and a spring is provided that closes the valve and closes the auxiliary suction passage when the valve closing force becomes smaller than a predetermined value. Fuel supply system for internal combustion engines.
