Diesel engines are well adapted by mankind because of their low fuel con sumption and better efficiency. In recent times researchers have focused more on alternate fuels, with the depleting trend of petro diesel. Biodiesel is the one of such alternate fuel whose calorific value nearer to diesel. Most of the researchers conclude d that with the usage of biodiesels the emissions can be reduced maintaining the consistency in efficiency, compared to diesel. In the present era of Nano technology there is the scope to improve the efficiency of engines using Nano additives in blended fu els. In this work single cylinder 4 stroke DI diesel engine is selected. The performance of different blends of mahua oil methyl esters for which cerium oxide (CeO 2 ) Nano additives of size 30 - 50 nm is added in different proportions in blended fuel. The experiment has been conducted with neat diesel fuel and diesel ? biodiesel blends (addition of cerium oxide (CeO 2 ) Nano additive) in a four stroke single cylinder direct injection (DI) diesel engine. Those results are compared with conventional diesel fuel, diesel ? biodiesel blends showed good performance, lower carbon monoxide (CO), and hydro carbons(HC) but higher oxides of nitrogen (NOx) emission.
