•Elaeocarpus Ganitrus (EG) seed oil was used for the synthesis of biodiesel.•B0.5 EG biodiesel blend results in higher BTE and good thermal performance compared to other blends.•It was evident that, EG blended biodiesels has lower CO, CO2, HC, NO emission and smoke opacity than diesel.•It was noted for all blended biodiesels, the emission was lower than that of diesel.•EG biodiesel can be blended with other biodiesel as additives for improving the performance and reducing the emission at effective cost. Researches in different countries have used predominantly seed oils for the production of biodiesel. In this research work, Elaeocarpus Ganitrus (EG) seed oil was used for the synthesis of biodiesel. Performance tests were carried out using biodiesel blends in single cylinder diesel engine and exhaust emissions were recorded using a five-gas analyser. EG biodiesel was blended with diesel in the ratios of 0.5%, 1%, 2%, 4%, 6%, 8% and 10% by volume. At full load, for B0.5 EG biodiesel blend (0.5% by volume), it was noted that 32.23% raise in Brake Thermal efficiency, 24.1% drop off in Brake Specific Fuel consumption, 50% decrease in CO emission, 15.25% decrease in CO2 emission, 49.15% decrease in HC emission, 19.14% decrease in NO emission and 11.6% decrease in smoke density. It was noted for all blended biodiesels, the emission was lower than that of diesel. The combustion characteristics of blended biodiesel closely follow that of diesel.
