摘要： A misfire-detecting system for an internal combustion engine detects a value of sparking voltage generated by the igniting device of the engine after generation of an ignition command signal, compares the value of the detected sparking voltage with a predetermined value, and determines whether or not a misfire has occurred in the engine, based upon the result of the comparison. The misfire-detecting system can discriminate between a misfire attributable to the fuel supply system of the engine and one attributable to the ignition system of the engine, from a detected peak value of the sparking voltage.

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-determining system for an internal combustion engine, in which an ECU detects misfires occurring in the engine. A first counter counts the number of times of occurrence of misfires detected every predetermined number of firing cycles, and a second counter counts the number of times of occurrence of misfires detected every predetermined repetition period which is a predetermined integer times as long as the predetermined number of firing cycles. The count value of the first counter is compared with a first reference value and a second reference value smaller than the first reference value every predetermined number of firing cycles, to determine that the engine is in a combustion state adversely affecting at least one exhaust system component part when the former is larger than the latter. Further, the count value of the second counter is corrected by an updated value of the first counter when the updated count value is smaller than the first reference value and at the same time larger than the second reference value, and reset when first counter count value is smaller than the second reference value. The second counter count value is compared with a third reference value, to determine that the engine is in a degraded combustion state.

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 spark plug 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 rate of variation in the detected value of the rotational speed of the engine is calculated over the firing period of the spark plug, and an average value thereof is then calculated. The calculated average value of the variation rate is compared with the calculated variation rate, and a cumulative value of a difference between the calculated variation rate average value and the calculated variation rate is calculated when the calculated variation rate is on the larger deceleration side of the engine rotational speed with respect to the calculated variation rate average value. The calculated difference cumulative value is compared with a predetermined value to determine whether or not the engine is in a degraded combustion state, based on the comparison result.
