ABSTRACT:
A combustion state-determining system for an internal combustion engine, includes an ECU which detects misfires occurring in the engine, calculates a rate of misfire occurrence every predetermined number of firing cycles, based on the detected misfires, and determines that the engine is in a misfiring state when the calculated rate of misfire occurrence exceeds a predetermined reference rate. Further, a temperature state of the engine is detected, and the predetermined reference rate is changed based on the detected temperature state.
