PROBLEM TO BE SOLVED: To improve rotational regularity in an internal combustion engine, and suppress discharge of a harmful matter by deciding a gauge of a torque contribution of each cylinder, and regulating a filling rate of the cylinder per cylinder with air or fresh gas by a controller. SOLUTION: Rotary motion of an angle transmission wheel 18 connected to an crankshaft of an internal combustion engine is detected by an angle sensor 14, and a segment time ti when the crankshaft passes an angle range having an exponent (i) is found out as a gauge of rotational nonregularity. A gauge mi of the filling rate of a cylinder having the exponent (i) is found out, and a segment time of a combustion stroke of a cylinder having the exponent (i) is measured. An average value of the gauge mi per cylinder of the filling rate of individual cylinder is found out. In the case where a torque of the cylinder is larger than an average value, the filling rate of the cylinder is decreased. In the case where the decreased torque is detected, the filling rate is increased.
