Abstract
Disclosed in an internal combustion engine control system for controlling at least one of the quantity of intake air and quantity of fuel supply, and to an internal combustion engine control system for controlling the air-fuel ratio of the mixture. The invention particularly relates to the control of the engine at a transition of operating condition. The former control system detects the change in one of the quantity of intake air and quantity of fuel supply and compensates the other, thereby controlling the engine by anticipation at a transition of control condition. The latter control system, as a first case, infers the mixture air-fuel ratio contributive to combustion so as to adjust fuel supply to the cylinder which is currently in the suction stroke, or, as a second case, infers the mixture air-fuel ratio in the same way as above so as to adjust the quantity of air taken in the cylinder which is currently in the suction stroke, both cases implementing the anticipation control so that the mixture air-fuel ratio is maintained within the prescribed range.
