ABSTRACT:
An air-fuel ratio control apparatus of an internal combustion engine controls the change in the amount of fuel discharged into an intake passage downstream of a throttle valve of the engine more smoothly in accordance with the change in the amount of fuel discharged into the intake passage upstream of the throttle valve. Thus, the air-fuel ratio of the air-fuel mixture fed into the cylinder of the engine is changed smoothly without causing a surging phenomenon to occur in the engine.
