Abstract
An exhaust gas post-processing system includes an oxidation catalyst configured to oxidize substances included in the exhaust gas; a diesel particulate filter configured to collect particulate matters included in the exhaust gas and disposed subsequent to the oxidation catalyst; a dosing module configured to inject a reducing agent and disposed subsequent to the diesel particulate filter; and a selective catalytic reduction configured to remove nitrogen oxide using the reducing agent included in the exhaust gas and disposed subsequent to the dosing module. The diesel particulate filter includes a catalytic component represented by La1-xAgxMnO3 (where 0<x<1).
