The present research was carried on to check the comparison of performance and emissions parameters of a single cylinder, naturally aspirated, 4-S, water cooled diesel engine when operated with diesel fuel, thumba biodiesel, and diesel–polanga biodiesel blends. The blends which were prepared are: 100% thumba biodiesel (T100), 50% diesel fuel with 50% of polanga biodiesel (P50), and 80% diesel fuel with 20% of polanga biodiesel (P20) were tested. The performance and emissions parameters of these blends and the diesel fuel under different load variations were tested. Based on the comparative analysis in between the fossil diesel, polanga biodiesel blends and thumba biodiesels, which resulted that, polanga biodiesel improved performance throughout the load condition by lowering the BSFC and increasing the BTE. In case of emissions, for polanga biodiesel resulted in lower carbon monoxide (CO), oxides of nitrogen (NOx), Carbon Dioxide (CO2) and Unused oxygen (O2) in the exhaust gas w.r.t diesel fuel.
