Abstract: To enhance the thermal efficiency, compression ratio in recent gasoline engines is becoming higher. In these engines, pre-ignition tends to occur due to higher temperature in the combustion chamber, that leads to lower engine performance and engine damage eventually. In order to detect pre-ignition and its precursory phenomenon, an ion-current sensor integrated in the ignition system is applied.
