Abstract

In the present investigation the high viscosity of the jatropha oil which has been considered as a potential alternative fuel for the diesel engine was decreased by blending with diesel. The blend of varying proportions of jatropha oil and petroleum diesel were prepared, analysed and compared with petroleum diesel fuel. The effect of fuel blend on the viscosity and calorific value was also studied. The performance of the engine using fuel blend between jatropha biodiesel oil with petroleum diesel was evaluated in single cylinder direct injection diesel engine. The brake specific fuel consumption, brake thermal efficiency, hydrocarbon emission, carbon dioxide emission and power produced from the combustion of engine was studied. Based on the investigation between B5, B 10 and B20 fuel blend, the acceptable fuel blend in this investigation is B5. B5 fuel blend is considered as an acceptable fuel blend because their viscosity and calorific value is nearly with petroleum diesel. In addition, based on the investigation, the value of brake thermal efficiency is better than petroleum diesel, B 10 and B20. The brake specific fuel consumption from the engine test also near with the value using petroleum diesel.
