Abstract: PROBLEM TO BE SOLVED: To provide a high reliability misfire discrimination reference. SOLUTION: The rotation angular velocity of an output shaft is measured corresponding to a rotation angle at each measuring point of time and a difference between the rotation angular velocity and an average rotation angular velocity is determined as an angular velocity fluctuation amount Fn. Further, based on a predetermined angular velocity fluctuation reference Fs and the angular velocity fluctuation amount Fn, an angular velocity fluctuation difference G is led out and based on the led-out angular velocity fluctuation difference G, an angular velocity fluctuation difference amount Da in a given stroke is led out.  In discrimination of the misfire state of an internal combustion engine based on the angular velocity fluctuation difference amount Da, in a first operation state considered as a normal operation state, the angular velocity fluctuation difference amount Da is detected a plurality of times. Probability distribution of the angular velocity fluctuation difference amount Da where the angular velocity fluctuation difference amount Da forms a probability function is determined. Based on the determined probability distribution, an angular velocity fluctuation difference reference value Dt to discriminate an abnormality combustion region is set and the misfire of an internal combustion engine is detected.
