Abstract
In the method of feedback controlling the air-fuel ratio of an internal combustion engine, the feedback control is stopped for a predetermined period of time at a specified time or condition of the engine, and the air-fuel ratio is controlled in accordance with a control signal having a value corresponding to the average value of the integrated compensation signals. In addition, a factor affecting the center value of the controlled air-fuel ratio is adjusted in accordance with the output signal of a comparator circuit generated during the time that the feedback control is being stopped.
