Abstract
A control apparatus, for an internal combustion engine, detects a rotational speed parameter (time parameter) that represents a rotational speed of the internal combustion engine including a plurality of cylinders, detects a single misfire that is a misfire for every ignition for each of the plurality of cylinders, based on the rotational speed parameter that has been detected in each combustion stroke of the plurality of cylinders (stepstoand), counts, as a misfire counter value, the number of times that the single misfire has been detected for each of the plurality of cylinders (stepsand), determines whether the misfire is occurring in the cylinder, based on the misfire counter value (stepsto), and corrects an ignition timing of the cylinder that has been determined that the misfire is occurring to an advance angle side (steps, and).
