    摘要： A combustion state-detecting system for internal combustion engines has a crank angle sensor which generates a crank angle signal with a predetermined period shorter than a firing period of the engine whenever the crankshaft rotates through a predetermined angle. A value of the rotational speed of the engine is detected whenever the crank angle signal is generated. A first average value of the detected engine rotational speed is calculated over every period of one rotation of the crankshaft, followed by calculating a second average value of the first average value over every firing period, to thereby calculate a rate of variation in the second average value over every firing period. Values of the rate of variation are averaged over a predetermined number of ignition cycles of the engine, to obtain a third average value. A cumulative value of the absolute value of a difference between the third average value and the rate of variation is calculated over the above predetermined number of ignition cycles. The cumulative value is compared with a predetermined value, to determine that the engine is in a degraded state of combustion, when the cumulative value exceeds the predetermined value.

    摘要： A combustion state-detecting system for an internal combustion engine calculates a first average speed by averaging the rotational speed of the engine over a time period corresponding to duration of one stroke of a cylinder, and a second average speed by averaging the rotational speed of the engine over a time period corresponding to duration of one cycle of all strokes of the cylinder. The system calculates a difference between the first average speed and the second average speed, and determines based on the difference whether or not the combustion state of the engine is abnormal.

    摘要： A misfire-detecting system for an internal combustion engine carries out self-diagnosis of the system. In the system, sparking voltage generated across a spark plug of a cylinder of the engine is detected, and the detected sparking voltage is compared with a first predetermined reference voltage value, and a time period is measured over which the detected sparking voltage exceeds the first predetermined reference voltage value. It is determined that a misfire occurred in the engine when the measured time period exceeds a predetermined time period value. It is determined whether the engine is in self-sustaining operation. When it is determined that the engine is in self-sustaining operation, it is determined whether the misfire-detecting system is abnormal. It is determined that the misfire-detecting system is abnormal when the detected sparking voltage is lower than a second reference voltage value. Alternatively or in combination, it is determined that the misfire-detecting system is abnormal when the detected sparking voltage has continued to be higher than a third predetermined reference voltage value over a predetermined time period.
