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

Abstract

PURPOSE: To make better the responsibility of mixing ratio control by directly controlling the negative pressure of Venturi tube.
CONSTITUTION: The air auxiliary pathway 6 serves to pass air from the upstream of the carburetor body 1 to the most contracted portion of the Venturi tube 3 under the control of the control valve 7 operated by suctional negative pressure for its opening and closing. The valve body 8 of the control valve 7 is closed when rod joint load is low and the throttle valve 2 is opened, but when the rod joint load becomes higher and the throttle valve 2 is opened, the suctional negative pressure becomes small, whereby the valve body 8 of the control valve 7 is opened, the air auxiliary pathway 6 is opened, air is flowed in right-angled manner at the most contracted portion of the Venturi tube 3 through the outlet 6', and the discharge of fuel from the nozzle 5 becomes greater. Thus, high mixing ratio can be obtained.
