- Abstract
The increasing use of diesel passenger cars has led to considerable work in the methods resulting in the reduction of particulate emissions. Interest is centered on reduction of emission in diesel engines from the new methods and technologies, diesel particulate filter, fuel additives for particulate matter. The objective of this research is to calculate various emission factors in diesel engine using cerium oxide nanoparticles. The experimental result reveals that the influence of cerium oxide in the form of nanoparticles for oxides of nitrogen, hydrocarbon and carbon monoxide levels in a diesel engine. The cerium oxide increase the conversion rate due to the oxygen content for the oxidation process of carbon monoxide and hydrocarbon in the catalytic converter. It was also observed that the cerium nanoparticles reduce the oxides of nitrogen effectively. The catalytic behavior in the higher temperature range enhanced the conversion of hydrocarbon and oxides of nitrogen, cerium nitrate precursor gives greater activity. Above 250°C, the conversion of HC, NOx increased and reached up to 98% conversion, when the temperature increased to 440°C.
