An experimental Investigation is carried out to study the performance and emission on Laboratory based direct injection, diesel engine fueled with Bio diesel (PaME), Diesel and DEE blended fuel taking pure Diesel as base line. The test fuels are pure Diesel, pure PaME, (95% PaME + 5% DEE in vol.), (80% Diesel+15% PaME+5% DEE in vol.), (95% Diesel + 5% DEE in vol.), and (80% PaME +15% Diesel +5% DEE in vol.) respectively. The experiment has been conducted at fixed engine speed of 1500 rpm and at compression ratio of 18.5. Engine tests have been conducted to get the comparative measures of Specific Fuel Consumption (SFC), Brake thermal efficiency (BTh) and emissions such as CO, CO2, HC, NO and NOX to evaluate the behavior of PaME, Diesel and DEE blends in varying proportions. A marked improvement in the trade-off between NOx and smoke was achieved maintaining a high thermal efficiency by a suitable combination between the parameters mentioned above for each engine load. The results with the combination 80% Diesel+15% PaME+5% DEE in vol. were found encouraging in all respects of performance and improved emission characteristics.
