Experimental Investigation on Performance, Emission and Ignition Delay Analysis of Biodiesel Addition in Diesel-Ethanol Blends

Abstract:

In this work biodiesel of various proportions has been blended with E20 (20% ethanol and 80% diesel). Bio-diesel concentrations are varied at 10%, 20% and 30% while ethanol concentration was maintained at 20%. Performance, emission and variation of ignition lag of the fuel blends were analyzed. There was a very good reduction in CO emissions by 28% in comparison with E20 and 80% in comparison with diesel. NOx emissions of the blends were decreased by 16% compared with diesel and no variation with E20. Brake Thermal Efficiency (bte) of the blends was higher by 11% up to 75% load and 4% at full load compared with diesel and lesser by 2% in comparison with E20. Ignition-delay of the blends was longer than diesel, and the cetane number of the blends were lower than diesel. Brake Specific Energy Consumption (bsec) is slightly higher than diesel.
