Abstract
A method for controlling the air-fuel ratio in an internal combustion engine in which the correction of the air-fuel ratio is carried out on the basis of the determination as to whether the base air-fuel ratio is the value in the richer or the leaner side of the air-fuel ratio corresponding to the best specific fuel consumption. A different number of operation points for detecting the signals of the parameters of the engine running state are selected for the automatic constant speed control state and for the non-automatic speed control state.
