比制御装置。An engine air-fuel ratio control device for a vehicle having air-fuel ratio feedback control means includes means for detecting engine water temperature, means for detecting a half-clutch state of an engine power intermittent clutch, and means for detecting a neutral state of a transmission gear. , means for detecting vehicle speed, and means for determining based on signals from each of the above-mentioned detection means whether the driving condition is such that the clutch is in a half-clutch state when the vehicle is started in a cold state where the engine water temperature is less than a predetermined temperature. and air-fuel ratio switching means for changing the control signal from the air-fuel ratio feedback control means to the fuel supply device so as to make the air-fuel ratio richer than during other idling or driving when it is determined that the above operating conditions apply. An air-fuel ratio control device comprising:
