ABSTRACT:
An intake air volume control device of an internal combustion engine capable of adjusting the intake air volume pertinently irrespective of a variation in characteristic such as a deterioration in durability, a variation in an engine water temperature or an intake absolute pressure or the like is provided. An intake air volume control device for an internal combustion engine in which there is provided a throttle opening degree control means for driving a throttle valve arranged in an air intake system of the internal combustion engine and adjusting an intake air volume comprises a target intake air volume calculating means for calculating a target intake air volume Q.sub.IDL in response to an external load of the internal combustion engine, and a target throttle opening degree setting means for setting a target throttle opening degree TH.sub.O in response to the target intake air volume calculated by the target intake air volume calculating means. The throttle valve is driven and controlled by the throttle opening degree control means in response to the target throttle opening degree TH.sub.O.
