소형 SI 기관용 연료로서 가솔린과 LPG의 특성 비교에 관한 연구

A Study in on the Comparison of Characteristics of Gasoline and LPG for a Small SI Engine

This is a fundamental study to improve the performance of the LPG engine. The result were summarized as followed. 1. The measured torque and power on the fuel of LPG were indicated about 8% lower than those on gasoline with the same compression ratio. 2. In the case of LPG, BSFD at compression ratio of 9.7 was about 5% lower than that of 8.3 at 3,000ppm 3. HC and CO concentrations of the LPG were lower about 53%, 35% than those of gasoline
