Development of Spark Plug for Ion Current Misfire Detection System
In this paper, the authors introduce the spark plug for misfire detection system by an ion current. In order to realize high accuracy misfire detection, the signal of the ion current must be larger than that of noise. To maintain the ion signal through its all lifetime, the figure and the initial dimensions of spark position are derived by an experiment and are given consideration about degradation in use. Additionally, by observations and a theoretical study, the authors show a relationship between the noise and the corona discharge on the insulator, and they indicate the method to inhibit the noise efficiently. Finally, the effect of the developed spark plug with these two methods is confirmed with the target engine, and the authors propose specifications of a spark plug that allows for high accuracy detection by the ion current.
