Abstract

PURPOSE: To increase carburetor acceleration performance and piston valve lubrication characteristics, an engine lubricating oil outlet hole is provided to the carburetor cylinder so that the hole faces the periphery of the piston valve.
CONSTITUTION: The periphery of the carburetor cylinder 10a is provided at its center of the suction side with an engine lubricating outlet hole 12 while opens against the periphery of the piston valve 20. The piston valve 12 is connected by tube 50 to the oil tank 51. The oil pump 52 quantitatively feeds engine oil between the internal of the cylinder 10a and external of the piston valve 20. This effectively seals upper internal of the cylinder and suction air passage of the carburetor. This also lubricates the cylinder internal and the piston valve external, thus effecting enhanced acceleration performance and piston valve lubrication characteristics.
