FUEL SUPPLY DEVICE OF A VEHICLE FOR CONTAINING THE AIR INTO FUEL SUPPLIED TO AN ENGINE BY INJECTING DIRECTLY THE AIR TO THE FUEL AND INCREASING THE AIR UTILIZATION RATE OF THE FUEL IN A COMBUSTION PROCESS OF A COMBUSTION CHAMBER

摘要

PURPOSE: A fuel supply device of a vehicle is provided to contain plenty of the air in the fuel by reinforcing or increasing contact between fuel and the air by supplying directly the air into fuel contained in a fuel tank and to improve combustion efficiency of the engine by securing perfect combustion in a combustion chamber. CONSTITUTION: A fuel supply device of a vehicle is composed of a fuel tank(10) for storing fuel to supply the fuel into a cylinder of an internal combustion engine; a fuel supply pump(20) for pumping the fuel from the fuel tank and feeding the fuel to a carburetor or a fuel injection device; fuel filters(15,21,22) for removing impurities from the fuel; a fuel pipe(24) for supplying the fuel sucked up from the fuel pump into the cylinder; a bubbling unit(12) installed at the lower side of the fuel tank to generate bubbles for reinforcing contact between the fuel and the air by discharging the air into the fuel tank; an air feed unit for supplying the air through an air feed pipe connected to the bubbling unit; and an air feed valve disposed between the bubbling unit and the air feed unit to regulate the amount and supply time of the air fed from the air feed unit.
