Effect of CeO2 Nano Additive on Performance and Emission Characteristics of Diesel Engine Fuelled By Neem Oil Biodiesel
An experimental study was carried out to study the performance, emission and combustion characteristics of single cylinder, direct injection diesel engine, air cooled diesel engine, fuelled with two modified fuel blends, BN20 (Biodisel from Neem oil) and Cerium oxide blended BN20 (Diesel 80% and 20% Biodiesel from neem oil on volumetric percentage) and the results are compared with standard diesel fuel operation. The cerium oxide nano additive was mixed with BN20 using Ultrasonicator device to achieve better stability. The properties of BN20 with and without nano additive were compared with standard diesel fuel. The addition of nano additive has resulted higher BSFC and BTE when compared to standard diesel fuel. In the case of emission, NOx, Smoke, HC and CO emissions reduced considerably by the addition of nano additive in the BN20 fuel blend. It is also observed that higher cylinder pressure and heat release during the cerium oxide blended BN20 fuel mode.
