Modem diesel vehicle has to comply with the EURO III, IV regulation with very low level of particulate and smoke emission. But diesel engine design technologies are inferior to gasoline engine. Recently, much attention have been focused on diesel exhaust aftertreatment system development. The reducing technologies of exhaust emission for diesel engine classified as common rail, EGR, fuel quality improvement, and development of diesel exhaust aftertreatment. The diesel exhaust aftertreatment technology is considered as the alternative technology in the near future. The diesel exhaust aftertreatment system has been advanced for reducing particulates and emission because it has simple in device structure, relatively low cost and easy to install the vehicle.<br/> In this study it was carried out conversion efficiency test for fresh and aged catalyst. Also it was evaluated the characteristics of exhaust gas and particulate matter emitted from catalyst according to the aging time then particulate matter reduce efficiency due to heat of oxidation reaction at diesel oxidation catalyst(DOC)<br/>
