스파크 플러그를 이용한 혼합기 농도 측정

Measurements of Mixture Strength Using Spark Plug

  • 발행 : 2000.07.01

초록

Ion current in an S.I engine cylinder is measured with the spark plug as a probe. The peak values are confirmed to show a fair correlation with local air-fuel ration and engine speed which implies that the ion current measured at the spark plug may provide a signal for the local mixture strength which is the key parameter in precise fuel control for future engines especially of gasoline direct-injected lean burn engines.
