[가솔린엔진] 가솔린기관에서 스파크플러그를 이용한 노킹 및 실화의 동시검출시스템의 개발에 관한 연구 = A Study on the knock and misfire detection system using by Spark-plug in a Gasoline Engine

다국어 초록 (Multilingual Abstract)

Knocking and mislire. kinds of abnormal combustion. are highly undesirable effect on the internal combustion engine. So. it is important to detect these abnormal combustion and control the ignition timing etc. to avoid these mal-effect factors in real engine system. In this study. the system which detect the knocking and misfire using by spark plug is presented. This system is based on the effect of modulation of the breakdown voltage(BDV) of the spark gap. The voltage drop between spark plug electrodes. when an electrical breakdown is initiated. depends on the temperature and pressure in combustion chamber. So. we can detect knock and misfire that produce changes in gas temperature and pressure (consequently, its density) by BDV signal change which carries information about the character of combustion.
