Abstract
A misfire-detecting system for an internal combustion engine having a plurality of cylinders. A rotational speed of the engine is detected and a rotational speed signal indicative of the detected rotational speed of the engine is output. The rotational speed signal is filtered. Occurrence of a misfire in the engine is determined based on the filtered rotational speed signal.
