ABSTRACT:
In an air-fuel ratio control device, a torque detector for detecting torque variations which indicate combustion variations in an engine is mounted at the supporting portions of the internal combustion engine. A detecting signal from the torque detector is introduced into an electronic control unit which controls the amount of injecting fuel, namely the air-fuel ratio. The electronic control unit controls the air-fuel ratio toward the lean side by the signal from the torque detector so that the combustion variations (torque variations) in the engine does not become large.
