Abstract: Ethyl ester of Jatropha oil (JEE) was prepared using acid catalysed transesterification method. The physico-chemical properties of JEE were determined. Blends of JEE were prepared with 5%, 10%, 15% and 20% butanol on volumetric basis. Performance, emission and heat release analysis of different blends were carried in a single cylinder diesel engine. Brake thermal efficiency (BTE) with JEE and its blends was higher than diesel. The emissions of CO, NO_x, and smoke for JEE and blends were lower while emission of HC was higher than diesel. The peak heat release rate for diesel and JEE100 were 135.41/°CA and 93.81 J/°CA.

Keywords: Jatropha ethyl ester; butanol; performance; emission.
