With abundance of forest and plant based non edible oils being available in our country such as jatropha, pongomia and castor oils, an attempt has been made to use these as substituent of diesel. But vegetable oils are not compatible with regular diesel (C.I.) engines, mainly due to the high viscosity of vegetable oils. Hence in our research we have tried to overcome this problem by reducing the viscosity and increasing the volatility. By careful review of literature and market survey we have come to the conclusion of selecting Jatropha Curcas and Castor oil blends. After successfully blending of biofuel after transesterification process we have tested its real application in a diesel engine. But before testing the Biodiesel in a C.I. engine we had make sure that the biodiesel derived from neutralized jatropha and cator oil is suited for use in diesel engines given that its kinematic viscosity, flash point, cloud point, and calorific value conform to the recommended international standards. So after this conformation we have carried out the performance analysis to get an idea about the practicality of the use of Jatropha and Castor oil as an alternative fuel.
