Evaluation of metal oxide nano particles in lemongrass biodiesel for engine performance, emission and combustion characteristics

Abstract

Abstract Physicochemical properties of lemongrass biodiesel and diesel engine parameters fueled with nanoparticles (Zinc Oxide, Titanium Oxide, and Alumina) added in diesel/biodiesel blended have been investigated, in which zinc oxide nanoparticles was green synthesized from ldenlandia leaf. The synthesized Zno Nps was characterized by Scanning Electron Microscope (SEM), X Ray Diffraction and FT-IR study. Each nanoparticles has own weightage of 50 ppm in 30% blend of lemongrass biodiesel/diesel. The performance, exhaust emission and combustion characteristics were performed for each lemongrass biodiesel nanoparticles blend using diesel engine and validation was carried out between each lemongrass biodiesel blends with diesel and ANOVA analysis was done to found out the dependency of parameters. It was concluded that characterization of ZnO, TiO2 and Al2O3 nanoparticles such as XRD, SEM and FT-IR was conformed their behavior in anatase phase along with lemongrass oil also characterized by FT-IR. From ANOVA table, B3050ZnO has major significant dependence for brake thermal efficiency over 3%. It was concluded that lemongrass biodiesel with green synthesized zinc oxide nanoparticles has better performance, emission and combustion characteristics over 5% among other two nano-additives.
