- Control Of The Air-Fuel Ratio Of Carburetors (AREA)
Abstract
PURPOSE:To prevent an overrich zone of air-fuel ratio from appearing in every operating region by partly opening a movable valve, which variably controls the passage area of a Venturi part, being associated with a throttle valve when its opening increases to a predetermined value or more. CONSTITUTION:When a throttle valve 3, provided in an intake cylinder 2 in a carburetor main unit 1, increases the opening and a flow amount of air in a Venturi part 5, metered fuel in a primary main jet 10 is mixed with the metered air in a primary main air bleed 9, and the mixture is jetted to the Venturi part 5 from a primary main nozzle 8. When the opening of the throttle valve 3 reaches a predetermined value, a cam plate 31, constituting an interlocking means 30, engages a cam surface 31a with a pawl part 32 of a lever 13, partly opening a movable valve 11. As the result, the Venturi part 5 increases its passage area, suppressing a Venturi negative pressure from increasing to the predetermined value or more. Thereafter, fuel is sucked from a secondary main nozzle 17.
