In both industrial and transportation sectors, petroleum consumption has been increasing tremendously. It is known that increase in demand of fossil fuels leads to exhaust of petroleum products in future. Biofuel is a fuel made by chemically reacting alcohol with vegetable oils, fats, or greases, such as recycled restaurant greases. The metal-based additives are used in order to improve the quality of fuel by reducing the unburn hydrocarbons in IC engines, to minimize the exhaust gas harmful emissions. In the present experimental work, an attempt is made at investigating the effect of Aluminum oxide and copper oxide nanoparticles addition in Mahua biodiesel in a single cylinder water cooled direct injection four stroke diesel engine. Initially experiments are conducted to optimize the blend of transeterified Mahua oil with diesel fuel with respect to Combustion, performance and emission parameters. The nano fluids have been prepared from 50 ppm concentrations of Aluminum oxide and copper oxide separately, through an ultra-sonication process. For optimized biodiesel of Mahua oil, the effect of nano additives on Combustion characteristics viz cylinder pressure, Heat release rate, performance parameters such as BTE, BSFC and emission parameters HC, CO, CO2, NOx emissions were evaluated and compared. In CI engines, with biodiesel usage reduces the emission particulates to the significant extent. Due to the presence of oxygen content in bio diesel, which causes increase in NOx formation. In this work there is significant reduction in emission oxides of nitrogen is noticed with nano additives due to control of in-cylinder temperature. Key words: Combustion, Nano fluids, Heat release rate, Cylinder pressure, Emissions
