Abstract
An intake air control device including swirl control means for controlling the intensity of a swirl in the combustion chamber. If combustion becomes worse during driving conditions under which a strong swirl should be created, an order means issues an order to actuate the swirl control means so as to weaken the intensity of the strong swirl. Next, a determination means determines whether combustion after the order is worse than combustion before the order, and when the result is negative, it is determined that a swirl control means problem has occurred.
