Zusammenfassung:	PROBLEM TO BE SOLVED: To perform compensation suitably in response to each of an error in a fuel system and an error in an air system to correct both an air fuel ratio variation and a torque variation.SOLUTION: When a difference between a target air fuel ratio and an actual air fuel ratio is a given value or less while feedback control based on an air fuel ratio of an exhaust pipe collection part 10A is implemented, the air fuel ratio of a cylinder cyl_1 in which a variation of angular acceleration is the greatest is corrected to the rich side by an increased amount of fuel, for example. Thereafter, angular acceleration of each cylinder is newly detected, and when the variation of angular acceleration between the cylinders is not solved, it is determined that there is an error in an amount of air control of the cylinder in which the variation is the greatest to correct an amount of air, an amount of fuel, ignition timing, and the like of the cylinder.
