FUEL SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; internal combustion engines; carburetor fuel systems. SUBSTANCE: proposed fuel system has carburetor, intake manifold with fitted on throttle valve housing and venturi. Smaller venturi is installed concentrically at venturi inlet and fuel atomizer is connected to its narrowing. Cone is installed concentrically at outlet. Cone angle is defined to provide required turbulization of air flow after cone. Cone is provided with teeth in base of side surface. Housing is installed on intake manifold through spacer whose diameter exceeds that of throttle valve. Diaphragm with toothed hole is provided in upper part of spacer. Parameters of teeth of cone and spacer are determined by minimum thickness of film of fuel flowing along teeth. EFFECT: improved atomizing of fuel, provision of complete combustion of fuel. 1 dwg
