Abstract
A control apparatus for an internal combustion engine performs a first acquisition process for acquiring a first index value corresponding to an integrated amount of intake air during a performance of the fuel cutoff process, and a cancellation process for cancelling the fuel cutoff process when the first index value becomes equal to or larger than a first predetermined value during the performance of the fuel cutoff process. Besides, the control apparatus performs a second acquisition process for acquiring a second index value corresponding to an elapsed time from the end of the fuel cutoff process to the subsequent start of the fuel cutoff process, and a change process for making the first predetermined value smaller when the second index value is small in starting the fuel cutoff process than when the second index value is large in starting the fuel cutoff process.
