ABSTRACT:
A combustion state-detecting system for an internal combustion engine comprises a rotational speed sensor for detecting a value of the rotational speed of the engine with a predetermined repetition period shorter than the firing period of the spark plug whenever the crankshaft rotates through a predetermined angle, and an ECU which calculates a difference amount between a value of the detected rotational speed of the engine and a value of the detected rotational speed of the engine a predetermined number of firing periods earlier. A combustion state of the engine is detected based on the calculated difference amount.
