Biodiesel was produced by adding ZnO nanoparticles as additives to the waste sunflower and kohlrabi grape seed oil. As a result of the examination of the produced fuels, it was observed that there was a decrease in CO, HC, and smoke emissions and an increase in NOx, CO2, and O-2. When these nanoparticle-doped fuel samples were compared with standard diesel fuel, improvements in emission values were obtained by adding ZnO nanoparticle additives to biodiesel fuel. These improvements were observed as a 35% reduction in CO, a 40% reduction in HC, and a 45% reduction in smoke (soot). The reason for this is that the nanoparticle additive increases the heat transfer coefficient of biodiesel fuel. Accordingly, it has a positive effect on in-cylinder temperature, pressure, ignition delay, and combustion time. It was concluded that the nanoparticle additive added to the fuel together with the observed reductions in emission rates provides a great benefit to the environment. In addition, an 11% reduction in specific fuel consumption was observed thanks to this nanoparticle additive. An improvement was observed in the emission values to the environment.
