摘要：An apparatus for treating an exhaust gas stream from cold startup throughcontinuous operating conditions of an internal combustion engine includes an oxidizingcatalyst bed disposed in an exhaust pipe and a reducing catalyst bed disposed in the

exhaust pipe downstream from the oxidizing catalyst bed. The oxidizing catalyst bed asone or more oxidizing catalysts and the reducing catalyst bed has one or more reducingcatalysts. A method is provided for treating an exhaust gas stream both during cold startand during continuous operating conditions of an internal combustion engine by passingthe stream through an oxidizing catalyst bed having one or more oxidizing catalysts at alight off temperature; a reducing catalyst bed having one or more reducing catalysts andproviding hydrogen into the reducing catalyst bed to condition the reducing catalyst; andintroducing hydrogen into the internal combustion engine during cold startup.
