Effects of Nanoparticles Additives on Performance and Emissions Characteristics of a DI Diesel Engine Fuelled with Biodiesel

This study investigates the use of copper oxide for Linseed oil based biodiesel. The metal based additive was added to biodiesel at a dosage of 40 μmol/L, 80 μmol/L and 120 μmol/L with the aid of an ultrasonicator. Experiments were conducted to study the effect of copper oxide added to biodiesel on performance and emission characteristics of a direct injection diesel engine operated at a constant speed of 1500 rpm at different operating conditions. Results show that maximum increase in brake thermal efficiency was found to be B20+ 80 PPM CuO and also reduces specific fuel consumption at full load conditions. The copper oxide additive is effective in control of hydrocarbon (HC), carbon monoxide (CO), smoke and oxides of nitrogen (NOx) at full load conditions.
