Abstract:
An exhaust gas treatment system for a diesel engine is disclosed. The exhaust gas treatment system includes a lean NOX trap (LNT) in fluid communication with a diesel engine to receive an exhaust gas flow therefrom. The system also includes a two-way catalyst in fluid communication with the LNT to receive the exhaust gas flow therefrom, the two-way catalyst comprising a urea selective catalytic reduction catalyst and a diesel particulate filter (DPF).
