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

Abstract

PURPOSE: To provide an appropriate air fuel ratio for the carbureter by supplying dilute fuel through a main nozzle and also supplying fuel through other main nozzle in response to the driving condition.
CONSTITUTION: A main nozzle 13 communication with a float chamber 6 through a main system fuel passage 11 is opened in a small Venturi tube 3 arranged in the suction air passage 1, and the supply of the dilute fuel is performed. Further, another main nozzle 22 is arranged in opposite to the main nozzle 13, and the nozzle 22 is communicated with the float chamber 6 through a main system fuel passage 20 for controlling the air fuel ratio, having a control valve 21. The control valve 21 is subejcted to feedback control by means of a control device 25 which receives a signal of an O2 senser 24 provided in the exhaust passage e3, and a mixture is supplied in response to the driving condition through both nozzles.
