Abstract

Plants like Prosopis Juliflora (PJF), which grows mostly in arid climates and regions where there is a semiarid climate, are non-edible feedstock’s for biofuels. PJF seeds undergo transesterification, which converts their biooil into biodiesel, to create biodiesel. This paper examines the performance and emissions of biodiesel extracted from the seeds of the PJF plant. The addition of cerium oxide nanoparticles supplies a catalyst that donates oxygen during combustion. Carbon deposits inside the engine cylinder are burned off by cerium oxide's activation energy by limiting polar compounds from depositing on the walls of the cylinders, HC emissions were decreased. EGR further reduced NOx emissions by treating exhaust gases. As a result, at all exhaust gas recirculation processes, PJF seed oil reduces smoke and NOx emissions considerably compared to Biodiesel.
