Abstract: The amount of emitted harmful emission gases increases in parallel with increasing energy consumption. This increase has forced many countries to take various precautions and various restrictions on emitted emissions have been carried. In this study, effects of addition of oxygen containing nanoparticle additives on NO_x emissions of diesel fuelled test engine were investigated. Nine different nanoparticle additives namely aluminium oxide (Al₂O₃), magnesium oxide (MgO), titanium oxide (TiO₂), zinc oxide (ZnO), silicon oxide (SiO₂), iron oxide Fe₂O₃, nickel oxide (NiO), nickel iron oxide (NiFe₂O₄) and nickel zinc iron oxide Zn_0.5Ni_0.5Fe₂O₄ were added to diesel fuel at the dosages of 25, 50 and 100 ppm. As a result, optimum additive and addition dosages were determined. Finally, the results showed that NO_x emissions were decreased with the addition of nanoparticles.
