Abstract: Bio-fuels are proved to be very good substitutes for the existing petroleum fuels. Blends of biodiesel extracted from Tamanu oil (B100, B80, B60, B40, and B20) along with induction of biogas with constant mass flow of 2.313 * 10⁻⁵ kg/s are used for conducting performance and emission analysis. The tests are carried out at 0%, 25%, 50%, 75% and 100% load conditions. Among the blends B20, B40 and B100 have shown a better performance with respect to brake thermal efficiency, mechanical efficiency and specific fuel consumption. All blends show reduction in HC when compared to diesel. But NO_x emission increases with increase in load. But, CO has slightly increased for the induction of biogas compared to the diesel at all load conditions. Experimental investigations show that blending of Tamanu oil methyl esters along with biogas can be used in diesel engine without any modification and also it reduces the harmful emissions.

Keywords: biodiesel; biogas; calophyllum inophyllum; Tamanu oil; dual fuel; performance and emission.
