Summary: | Catalyzed diesel particulate filter (CDPF) is an effective way of reducing the carbon particles contained in the emissions of diesel vehicles. The behavior of the oxygen of cerium composite oxides during carbon combustion was investigated using isotopic oxygen to oxidize carbon particles trapped in the CDPF. The released oxygen from cerium composite oxides was used in the oxidation of carbon particles at lower temperatures. The effect of oxygen release coincided with the effect of temperature for carbon particle oxidation, so that CePr composite oxides that released oxygen at the lowest temperatures caused carbon oxidation from the lowest temperatures. Therefore, improvement of the oxygen release property of cerium composite oxides will reduce the temperature required for the oxidation reaction of carbon particles in the CDPF. |
