ABSTRACT:
A misfire-detecting system for an internal combustion engine includes a temperature sensor for detecting a temperature of the engine, and an ECU which carries out detection of a misfire occurring in the engine when the detected temperature falls within a predetermined region. A load condition of the engine is detected, and the predetermined region is changed according to the detected load condition of the engine.
