FUEL SUPPLY DEVICE FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To normalize the function of a fuel pump, and to improve hot startability of an engine by discharging fuel vapor generated in a pump chamber of the fuel pump to the fuel reservoir side with an air vent when starting the engine. SOLUTION: This fuel supply device supplies fuel of a fuel reservoir 35 to the engine E by connecting a delivery port 31a of the fuel pump 21 for pumping up the fuel of a fuel tank 26 by drive of the engine E to an inflow port 36a opened and closed by a float valve 37. A second delivery port 31b is arranged in the fuel pump 21, and a second inflow port 36b having no float valve is arranged in the fuel reservoir 35, respectively. These second delivery port 31b and second inflow port 36b are connected via a solenoid valve 39 opened while starting the engine E.
