Disclosed is an electronic closed loop air-fuel ratio control system having a control means which generates a control signal which controls the air-fuel ratio and which is a function of both the air-fuel ratio and the direction of change of the ratio, such that If, for example, the signal from the exhaust gas sensor indicates that the air-fuel mixture is "rich" and the magnitude of the signal is within a predetermined regulated to become "rich" in order to quicken the response of the air-fuel ratio control system.
