Abstract
A control system equipped with a misfire detection apparatus for an internal combustion engine comprising a first storage for storing a data train indicative of a record of a predetermined number of the operation states detected at a predetermined interval and a second storage for storing a reference data train indicative of a reference record of a predetermined number of reference operation states. The misfire detection apparatus further includes a comparison calculator for comparing each data constituting the data train stored in the first storage with each data constituting the reference data train stored in the second storage to obtain a comparison result between the entire data train and the entire reference data train. The comparison result supplied to a decision section to decide that the engine is in a predetermined state when the comparison result is out of a predetermined range.
