Abstract
Control apparatus for an internal combustion engine including: a second knock detection unit for detecting occurrence of a second knock due to an effective compression ratio when ignition timing is on a retard side of a predetermined value in the case where a first knock is detected; a second knock suppression unit for suppressing the second knock when the second knock is detected; a first abnormal ignition detection means for detecting occurrence of first abnormal ignition due to the pre-ignition or the post-ignition when a knock intensity of the second knock is equal to or larger than a predetermined value; and a first abnormal ignition suppression unit for suppressing the first abnormal ignition by performing fuel control for the internal combustion engine when the first abnormal ignition is detected.
