    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 connector disposed at a distal end of a high tension cord having a conductive core therein for carrying an ignition voltage current for igniting air-fuel mixture in an internal combustion engine. A conductive connecting member is connected to the conductive core and a cover made of an insulation material is disposed therearound. A conductor is embedded in the insulation cover such that it locates around the conductive connecting member keeping a predetermined distance therefrom and sandwiching a portion of the insulation cover, 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 conductive connecting member and the conductor. A ceramic insulator can be positioned between the conductor and the conductive connecting member section. The conductor can further be electrically shielded. The cover has a portion to be firmly secured with a mated portion of a device such as an inlet connector of an ignition distributor so as to be held there in position.
