Abstract: Internal combustion engine are established as the main power source for automobile vehicles. At present emission norms because strict for any I.C Engine. The main pollutant are CO, HC, NOx, PM, soot etc. the aim of this work is to inject inject nanoparticle to reduce the emission norms like CO, HC, NOx, PM, soot and by using after treatment devices. Cerium oxide being oxygen buffering capability, especially in the nanosized form, hence when used as an additive in the diesel fuel it leads to simultaneous reduction and oxidation of nitrogen dioxide and hydrocarbon emissions, respectively from diesel engine. However , the work investigates the effect of ceriumoxide nanoparticles on emissions of diesel engine.

Keywords: Internal combustion engine, Nanoparticles, Nitrogen dioxide, Catalytic converter
