Biodiesel can be used as a supplementary fuel in diesel engines and it will be implemented in automotive fleets and power genset diesel engines in near future in our country. There is lot of studies available in literatures on use of biodiesel blends in unmodified diesel engines. However, it is reported NOx emission and SFC increases with the blends in the engine. It is the major problems for use of biodiesel blends in unmodified or in-use engine. The motivation of the study is to enhance performance and emission characteristics of a diesel engine for use of biodiesel by modifying fuel quality. The studies were carried out in a single cylinder, constant speed diesel engine with rated power of 7.4 kW. The percentage of karanja biodiesel in diesel was kept as constant (B20) throughout the study where as percentage of Diethyl Ether (DEE) was varied from 5% and 10% (by volume) in the biodiesel blend. The smoke opacity (%) decreased significantly for all loads.
