Utilization of Aluminum Oxide Nano Particles in Dairy Scum Methyl Ester Biodiesel Engine

Abstract

In response to the pressing need for sustainable energy solutions and environmental concerns, this study investigated the utilization of Waste Dairy scum methyl ester biodiesel blended with diesel and enhanced with Al₂O₃nanoparticles as an additive. Waste Dairy scum methyl ester biodiesel was prepared and blended with diesel and Al₂O₃ (100ppm) nanoparticles as additive. The performance and emission parameters of a single cylinder diesel engine were experimentally tested with use of neat diesel, biodiesel blends of B30 with (B30+ Al₂O₃) and without additive of Al₂O₃ nanoparticles. At peak load conditions B30+ Al₂O₃ resulted with lowest BSFC in comparison with neat Diesel and B30 biodiesel. The BTE with B30+Al₂O₃ was 2.31% higher than that of diesel and 2.06 % higher than B30. CO emission was reduced by 16.66% with use of B30 and B30+ Al₂O₃ compared to diesel. The Carbon dioxide emission was found reduced with use of Al₂O₃ Nano particles in comparison with diesel and B30 by 4.27% and 2% respectively. The HC emission was reduced by 7.69% and 13.46% with use of B30 and B30+ Al₂O₃ respectively. The addition of Nano particles has contributed for the improved performance and reduced emissions when compared to B30 Bio Diesel blend and Neat Diesel. This research addressed both the energy and environmental challenges.
