PERFORMANCE, EMISSION AND COMBUSTION CHARACTERISTICS OF A METHYL ESTER SUNFLOWER OILEUCALYPTUS OIL IN A SINGLE CYLINDER AIR COOLED AND DIRECT INJECTION DIESEL ENGINE

摘要

Biomass derived fuels are preferred as alternative fuels for IC engine due to its abundant availability and renewable nature. In the present work the performance, emission and combustion characteristics of a single cylinder constant speed , direct injection diesel engine using methyl ester of sun flower oil eucalyptus oil blend as an alternative fuel were studied and the results are compared with the standard diesel fuel operation. Result indicated that 50% reduction in smoke, 34% reduction in HC emission and a 37.5% reduction in CO emission for the MeS50Eu50 blend with 2.8 % increase in NOx emission at full load. Brake thermal efficiency was increased 2.7 % for MeS50Eu50 blend.
