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

Abstract

PURPOSE: In the apparatus for detecting one componeny in exhaust gas and for controlling the carburetor air-fuel ratio at the environment of the theoretical air-fuel ratio, the main control valve for carbutretor and the slow control valve are controlled by one electromagnetic valve, and the simplification of the control system is schemed.
