摘要:
An emission treatment system for a vehicle having an internal combustion engine is disclosed. The emission treatment system has an HC-SCR catalyst including a non-Pt group metal dispersed in a ceramic matrix configured to receive an exhaust gas flow from an engine. The system also has an oxidation catalyst comprising a Pt group metal configured to receive the exhaust gas flow from the HC-SCR catalyst. The system also has a U-SCR catalyst and a diesel particulate filter, one of the U-SCR catalyst or the DPF configured to receive the exhaust gas flow from the oxidation catalyst and the other one of the U-SCR catalyst or the diesel particulate filter configured to receive the exhaust gas flow from the respective one.
