The Use of Gas Chromatograph for the Measurement of Engine Exhaust Gas Composition

엔진 배기가스 성분 측정 을 위한 Gas Chromatograph 의 이용

In this study the usefulness of Gas Chromatograph for the measurement of engine exhaust gas composition was confirmed. It was found that the composition of standard gas which was used for the calibration of Gas Chromatograph should not be greatly different from that of exhaust gas. Although self-evident, it cannot be overemphasized that utmost attention should be paid to prevent even a minute amount of air being mixed into the gas throughout the sampling process.

본 연구에서는 Gas Chromatograph를 사용하여 1,500㏄급 국산 소형 승용차 엔 진의 배기가스 성분을 분석하였다. 그리고 이를 통하여 배개가스 성분 분석에 Gas Chromatograph를 사용할 경우 아래와 같은 점에 유의한다면 배기가스 성분을 비교적 정확하게 측정할 수 있다는 것을 확인하였다.
