Abstract
A control device for an internal combustion engine includes an electronic control unit configured to predict a first intake air amount in a case where an overlapping period in which both of an intake valve and an exhaust valve of a cylinder of the internal combustion engine are open is set to be a first period, predict a second intake air amount in a case where the overlapping period is set to be a second period shorter than the first period with a valve timing of the exhaust valve being advanced, predict that scavenging will occur in the overlapping period in a case where the first intake air amount is greater than the second intake air amount, and predict that the scavenging will not occur in a case where the first intake air amount is equal to or smaller than the second intake air amount.
