Abstract: A combustion control apparatus includes a sensor sensitive to a combustion condition in at least one of the cylinders for producing a sensor signal indicative of a sensed combustion condition, and a control unit connected to the sensor for controlling an engine operating condition to adjust the combustion condition to a target value. A difference of the sensed combustion condition from the target value is calculated. An abnormal combustion indicative signal is produced when the calculated difference is negative value less than a limit value below which the combustion condition is degraded to an unacceptable extent. The engine operating condition is corrected at a first rate to maintain the target value of the combustion condition in the absence of the abnormal combustion indicative signal and at a second rate greater than the first rate in the presence of the abnormal combustion indicative signal.
