연소모사장치를 이용한 LPG 직접분사식 엔진 연소특성 연구

Abstract

Combustion characteristics of LPG (Liquified petroleum gas) fuel were observed by flame visualization using ICCD camera at CVCC (Constant Volume Combustion Chamber). The results of burning rate showed that 30°inlet port has the est result with little difference. The condition of flow in the CVCC showed the fastest combustion propagation in the 30°angle of inlet port. The effect that the shot combustion delay period and the strong flow was found in every experiment condition. In addition, in case of that equivalence is 1.0, the speed of combustion is so high.
