PROBLEM TO BE SOLVED: To reduce rotational fluctuation by a simple structure, by diminishing the rotational fluctuation on the basis of prediction from rotational fluctuation of each previously memorized ignition of each air cylinder from the engine speed of an internal combustion engine and the crank angle of each air cylinder. SOLUTION: Engine speed detecting means 30 comprises a pulser coil arranged to be opposed to the projection 36 of a crankshaft 5, and the upper part of the engine speed is transmitted to control means 34. Crank angle detecting means 31 comprises a crank angle sensor arranged to be opposed to the gear 37a of a wheel 37 arranged on the crankshaft 5, and the upper part of the crank angle of each air cylinder 2 is transmitted to control means 34. Also, rotational fluctuation detecting means 32 is arranged on the air cylinder 2 of an internal combustion engine 1, and an upper part of rotational fluctuation after each air cylinder 2 is ignited is transmitted to control means 34, and this rotational fluctuation is previously memorized in memory means 35. Then, the control means 34 controls a mistire condition so as to diminish the rotational fluctuation on the basis of prediction from patterns of previously memorized rotational fluctuation of each air cylinder from the information of an engine speed and information of the crank angle. |
