摘要： The arrangement for mounting a sparkplug of an internal combustion engine includes mounting the sparkplug so that all of the outside electrodes are arranged at an intake port side area and/or an exhaust port side area. Alternatively, in the case where at least one of the outside electrodes is located outside of the above-mentioned areas, no other remaining outside electrodes are arranged at a position that faces that outside electrode across the central electrode.

A charge quantity Q of the capacitor C at discharge start is set so that, as a consequence of a discharging operation of the capacitor C, discharge duration required until the current value of the detection resistor R2 falls below the predetermined value becomes longer than time duration in which the ion current generated by fuel combustion in the engine combustion chamber lasts. The ion current detecting apparatus automatically detects degradation in an insulation resistance in the spark plug, ensuring normal operation in engine control.

摘要： Provided is a method for determining a combustion state of a spark-ignited internal combustion engine including an ignition plug to ignite a fuel-air mixture by a plasma generated by a reaction between a spark discharge generated by a high voltage applied through an ignition coil connected to the ignition plug and an electric field generated in a combustion chamber. In the method, a change in a secondary voltage secondarily generated in the ignition plug after the spark discharge in association with the spark discharge is detected. A case where the change in the detected secondary voltage deviates from a predetermined range is determined as an occurrence of misfire. This enables detection of a misfire state without being hindered from an ion current due to the plasma remaining in the combustion chamber.
