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, NOx, 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.
