御装置。This is a feedback air-fuel ratio control device that controls the air-fuel ratio to be leaner than the theoretical value by using means to determine the deviation between the target value and the measured value of the air-fuel ratio. The air-fuel ratio is corrected to a target value by diverting air from upstream of a meter or venturi to downstream of a throttle valve, and controlling the amount of diverted air by a negative pressure downstream of the throttle valve based on a signal from the determining means. An air-fuel ratio control device for an internal combustion engine, characterized by:
