Abstract
A control apparatus for an internal combustion engine includes: an abnormal combustion detection unit for detecting an abnormal combustion due to self-ignition occurring; a pre-ignition determination unit for detecting abnormal combustion occurrence timing based on abnormal combustion detection information to determine whether or not the abnormal combustion is the pre-ignition based on comparison between pre-ignition determination timing and the abnormal combustion occurrence timing; a heat-source pre-ignition determination unit for determining whether the pre-ignition is the heat-source pre-ignition or the compression pre-ignition based on comparison between the abnormal combustion occurrence timing set by the pre-ignition determination timing and heat-source pre-ignition determination timing; a first avoidance unit for avoiding the heat-source pre-ignition in a case where the pre-ignition is determined as the heat-source pre-ignition; and a second avoidance unit for avoiding the compression pre-ignition in a case where the pre-ignition is determined as the compression pre-ignition.
