Abstract: In this current study, Collection of Seeds ,Extraction of Oil and Transesterification of Biodiesel ,Physical–Chemical properties and Emission properties, with mixed dual fuel of jatropha curcas , pongamia pinnata biodiesels mixture - diesel blend in equal proportions with conventional mineral diesel in the proportions of B5,B10,B15,B20 with ratios of (50:50),(60:40),(70:30) and the results were compared with diesel. FTIR test , Fatty Acid Profile, Physico chemical properties such as Density, Kinematic viscosity, Calorific value, flash and fire points and Emission properties such as CO , CO2 , HC , Nox  smoke percentage ,Exhaust gas temperature, were determined by using the standard test methods and compared with conventional diesel fuel.

Keywords: Dual Bio-fuel, Physical Chemical Properties, Emission, Blending, Transesterification
