This study inspects the emission and performance patterns of the mango seed biodiesel-fuelled diesel engine with zinc oxide nanoparticle at various particle sizes (20 and 40 nm) and the results are compared with conventional diesel fuel (BD). The inclusion of 20 nm particle size of ZnO nanoparticle in M100 improves the overall combustion process and promotes a lower level of smoke emissions, carbon monoxide (CO), hydrocarbon (HC), and oxides of nitrogen (NOx) emissions. The inclusion of 40 nm particle size of ZnO nanoparticle in M100 further reduces the NOx, HC, CO, and smoke emission by 4.1%, 2.89%, 3.69%, and 3.58%, respectively, at all load conditions than neat biodiesel. In addition, brake thermal efficiency is improved by 1.3% with 1.8% reduction in brake-specific fuel consumption.
