Abstract
An air-fuel ratio control system for an internal combustion engine for controlling the air-fuel mixing ratio of a combustible mixture to be supplied to the engine on a feedback control scheme in dependence on the concentration of a constituent of exhaust gases which is a function of the air-fuel mixing ratio of the combustible mixture having been combusted. The feedback control scheme of the air-fuel ratio control system for adjusting the ratio to the stoichiometric value is temporarily disconnected to permit the mixture to be enriched so that the engine can produce a relatively high power output during the high load engine operating condition.
