Experimental studies on the combustion characteristics and performance of a naturally aspirated, direct injection engine fuelled with a liquid petroleum gas/diesel blend:

摘要: This paper studies the combustion characteristics and performances of a LPG/diesel blend-fuel engine; influences mixing ratio LPG in diesel on ignition timing, in-cylinder pressure, heat-release rate, specific fuel consumption, power output, exhaust emissions have been identified. The results indicate that delay blend was obviously longer than higher diesel, delay. When 10 per cent, peak gas pressure rate rise were slightly those corresponding crank angles at which values occurred almost same as diesel. 30 lower retarded. With increasing heat release increased equivalent consumption L10 but L30 slight higher. output engine speed characteristic full load, especially high speed. ratio, smoke NO x greatly reduced, CO decreased too, HC increased.
