ABSTRACT:
An internal combustion engine air-fuel ratio control method and apparatus wherein a most favorable parameter selected from the group consisting of air, fuel, and recirculated exhaust gas is adjusted in response to detected deviation of the air-fuel ratio away from the desired ratio. Supplemental control is provided by means of the remaining parameters in the event that the most favorable parameter runs out of authority.
