dc.description.abstract | In recent years, several methods to regenerate PM (Particulate Material) from DPF (Diesel Particulate Filter) have been developed to meet getting more stringent emission regulations. A favorable technology is NO₂-assisted regeneration method due to the capability of continuous regeneration of PM under much lower temperature than that of thermal regeneration. Onechannel numerical modeling of integrated 'DOC(Diesel Oxidation Catalyst)+DPF' system has been adopted in order to predict transient thermal responses of monolith during regeneration and conversion rate of NO₂ from NO. The effects of catalyst loading and the volume ratio between DOC and DPF on conversion and regeneration efficiency have been numerically investigated. The results indicate that the model of 'volume ratio of DOC/DPF=1' with a constant and same diameter of monolith showed the best performance in conversion and regeneration efficiency. About 90 ㎠/㎤ of catalyst(Pt) loading under the engine operating condition in this study was enough to maximize the conversion and regeneration efficiency. | - |
