摘要： A misfire-detecting system detects a misfire occurring in an internal combustion engine. A value of sparking voltage for discharging a spark plug of the engine is detected. A differentiating circuit differentiates the detected value of the sparking voltage. A misfire-determining circuit compares the differential value of the sparking voltage with a predetermined value, and determines, based upon a result of the comparison, whether a misfire has occurred in the engine.

摘要： An ignition coil has a capacitor for detecting ignition voltage of a spark-ignition internal combustion engine to determine if misfire occurs. The ignition coil has a primary winding and a secondary winding both wound around a core. A connector section, connected to the secondary winding by a lead, is provided for receiving a high-voltage cable to transmit the secondary winding voltage current to an ignition distributor. These components are embedded integrally in an insulator resin at the time of completing the coil. A conductor is also embedded in the insulator resin such that it is located around the connector section keeping a predetermined distance therefrom and sandwiching the insulator resin, whereby a capacitor, which constitutes a capacitive divider in cooperation with a second capacitor for detecting misfire through the ignition voltage, is formed between the connector section and the conductor. A ceramic insulator can be positioned between the conductor and the connector section. The conductor can further be electrically shielded.

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.

摘要： A control system for an internal combustion engine determines ignition timing of the engine and generates an ignition command signal to generate high voltage for discharging a spark plug provided for each cylinder of the engine. The control system detects sparking voltage generated across the spark plug when the high voltage is generated. The control system measures a duration over which the sparking voltage across the spark plug exceeds a predetermined reference value, after generation of the ignition command signal. According to a first aspect of the invention, the control system detects combustion roughness based on the duration measured. According to a second aspect of the invention, the control means detects an air-fuel ratio of an air-fuel mixture supplied to the engine, based on the duration measured.

摘要： A misfire-detecting system detects a misfire occurring in an internal combustion engine. A value of sparking voltage for discharging a spark plug of the engine is detected. The detected value of the sparking voltage is compared with a first predetermined value. A degree to which the detected value of the sparking voltage exceeds the first predetermined value is measured. The measured degree is compared with a second predetermined value. It is determined based upon results of the latter comparison whether or not a misfire occurred in the engine. According to a first aspect of the invention, the second predetermined reference value is set based upon detected values of operating parameters of the engine. According to a second aspect of the invention, the determination of occurrence of a misfire is inhibited when the engine is in a predetermined operating condition.
