ABSTRACT:
Disclosed herein is a variable venturi carburetor adapted for controlling the air-fuel ratio by air bleeding operation which includes an actuator for controlling the amount of bleed air in response to the engine running conditions and a fuel jet having a fuel metering portion and an air bleed portion provided downstream of and adjacent to the fuel metering portion. The air bleed portion has an outlet opening adapted for delivering bleed air into the fuel passage and the inside diameter of the air bleed portion is designed to be slightly larger than that of the fuel metering portion. Especially, at engine idle operation, the restriction area of the air bleed portion is designed to become larger than that adjusted by the actuator and the inside diameter of the fuel passage downstream of the air bleed portion is designed to become large in such a manner that air and fuel flows may not be influenced by the restricting operation of the air bleed portion.
