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

Abstract

PURPOSE: To atomize fuel and obtain an adequate air-fuel ratio, by injecting air controlled in accordance with a signal of an exhaust gas component, to a place at a face-to-face position to main and slow line fuel passages in a carburetor.
CONSTITUTION: A main nozzle 13 communicated to a float chamber 6 having its opening to a small (primary) venturi 3 is provided simultaneously a main air nozzle 23 located at a face-to-face position to the nozzle 13 and having a solenoid on-off valve 22 further communicated to an air control line 21 is arranged. While in the vicinity of a slow port 17 in a slow line system the opening of a slow air line 26 communicated to an air cleaner A at its one end is provided simultaneously on its half way a solenoid on-off valve 27 is arranged. On-off valves 22, 27 are open-close controlled by a control circuit 25 that receives a signal from an exhaust gas sensor 24 provided in an exhaust gas passage e3.
