  • Control Of The Air-Fuel Ratio Of Carburetors (AREA)

Abstract

PURPOSE: To atomize the fuel in a variable venturi carburetor by introducing vacuum into an atmosphere chamber defined by a suction piston when the opening degree of a throttle valve is small, so that the piston is moved to a more closed pisition thereby increasing the velocity of the air-fuel mixture.
CONSTITUTION: A suction piston 7 movable in the upward and downward direction corresponding to the venturi vacuum which acts on a vacuum chamber 13 defines an atmosphere chamber 12 into which an atmosphere is introduced through a vent port not shown. This atmosphere chamber 12 is also introduced with a vacuum generated between the piston 7 and a throttle valve 2 through a vacuum passage 17 including a valve 15. The valve 15 cooperates with the throttle valve 2 through a linkage 24 and a cam 19 in such a manner that when the opening degree of the throttle valve 2 is small, the valve 15 is opened so as to introduce a vacuum into the atmosphere chamber 12, which vacuum closes the piston 7.
