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

Abstract

PURPOSE: To produce a proper air fuel ratio by actuating the venturi member of variable venturi carbureter in response to an intake air volume by feeding the fuel making the opening of member to feedback.
CONSTITUTION: A venturi member 3 is provided to open/close automatically respondent to the intake air volume for the upper flow of throttle valve 2 positioned within the intake passage 1, by the actuation of the member 3 a constant negative pressure of chamber 4 located between both valves 2 and 3 is maintained. Thus, said negative pressure actuates the fuel nozzle 16 opened at the down-flow of throttle valve 2 by means of the passage 17 for feeding the fuel within float chamber 13 to the intake passage 1. The opening of member 3 is transmitted to electronic controller 22 by the opening sensor 21 with said opening to compensate by the diaphragm unit 5 whereto the negative pressure of chamber 4 is applied, permitting the opening compensation of open/close valves 20, 20a located at the fuel passage 14 to perform by said unit 22.
