India is the upcoming industrial revolution, wherein its economy and its fuel consumption have been rising drastically over the past two decades. Petroleum resources are depreciating rapidly in the world biofuels and its blends are the alternative sources for stabilizing demand and supply. Biofuels are eco-friendly and substitute for conventional fuels. When compared to fossil fuels except for nitrogen oxide (NOx) remains emission particles are reduced. For effective reducing, NOx, an Exhaust Gas Recirculation system (EGR) is used as exuberance for a diesel engine. The present investigation carried on Coconut oil blend (CBD20) and Cottonseed oil blend (COBD20) biofuels was prepared by the transesterification process with Al2O3 as catalyst on a diesel engine with different EGR percentage ratios (10, 15, and 20%). In this analysis emission, performance parameters and exhaust gas temperature are measured and compared with two biofuels. In this study compared with neat diesel, EGR shows a better improvement on NOx level and performance levels are greasy.
