Experimental investigations with zinc oxide and silver doped zinc oxide nanoparticles for performance and emissions study of biodiesel blends in diesel engine

Abstract

The present study investigates the effect of Silver doped zinc oxide (Ag-ZnO) and Zinc Oxide (ZnO) nanoparticles fuel additives on the performance and emission characteristics of diesel engine. The ZnO and Ag-doped ZnO nanoparticles (NPs) prepared by the hydrothermal method. After the preparation, the XRD pattern of ZnO and Ag-doped ZnO NPs revealed hexagonal wurtzite structure and calculated their crystallite size was 19 and 37 nm. FTIR spectra confirmed the presence of Ag and Zn-O vibration modes. The micrograph (or nano) of scanning electron microscopy and transmission electron microscopy shows the spherical shape with less agglomerated ZnO and Ag-doped ZnO NPs. Both ZnO and Ag-doped ZnO NPs were added in Pongamia B20 biodiesel blends with the various proportions as an additive. Furthermore, the experimentally measured results exhibited significant emission (CO, NOx) properties of biodiesel blends with the addition of ZnO and Ag-ZnO NPs in diesel engines.
