比制御装置。 An air-fuel ratio control device for a multi-cylinder engine, in which an exhaust sensor is disposed in an exhaust passage into which exhaust gas from each cylinder is introduced, and the air-fuel ratio is feedback-controlled to a predetermined value based on the output of the sensor. An air-fuel ratio of a multi-cylinder engine, characterized in that the air-fuel ratio of a multi-cylinder engine is provided with a control means for converging the air-fuel ratio to a value other than the predetermined value by varying the amount of fuel supplied to the cylinder closest to the cylinder and the other cylinders. Control device.
