Abstract: In present work, Simarouba seed oil has been evaluated as a feasible feedstock for biodiesel production. An optimum yield of 98.1% was achieved at a temperature of 55°C; methanol/oil molar ratio as 6:1; time duration of 60 min; and catalyst concentration of 1 wt. %. Then, the Simarouba biodiesel-diesel blends were tested to assess the performance of engine and its emission characteristic. The B10, B20, B30, and B50 blends of Simarouba methyl ester (SME) showed average reduction of 2.8, 6.5, 7.8, and 14.3% in BTE respectively and an average 3.18, 5.94, 7.18, and 15.54% higher energy consumption than mineral diesel. At higher load conditions UHC, CO, and smoke emissions were found lesser while CO2 and NOx emissions were found higher for all SME blends in comparison to diesel.
