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 NOx 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 Zn0.5Ni0.5Fe2O4 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 NOx
emissions were decreased with the addition of nanoparticles.
