摘要： An engine system includes an electronically controlled compression ignition engine configured to burn diesel fuel to produce an exhaust with a temperature and NOx to soot ratio. An aftertreatment system is fluidly connected to the engine and includes a diesel oxidation catalyst, a reductant supply, and a diesel particulate filter coated with a NOx reduction catalyst but not the diesel oxidation catalyst. A soot load density in the diesel particulate filter is stabilized by oxidizing soot at about a same rate as the compression ignition engine is supplying soot to the aftertreatment system without active regeneration. A NOx reduction reaction is catalyzed by the NOx reduction catalyst on the diesel particulate filter.

摘要： Catalysts, systems, and methods disclosed herein provide for reduced NOx emissions in the exhaust stream of a lean burning engine. The catalysts include two different types of selective catalytic reduction (SCR) catalysts (i.e., two different types of catalysts that may catalytically reduce NOx using a reductant). The first SCR catalyst (116) is an SCR catalyst having a composition that produces a reductant (e.g., an HC-SCR catalyst that produces ammonia) and the second catalyst (118) is an SCR catalyst (e.g., NH3-SCR) having a composition that reduces NOx using the reductant produced by the first SCR catalyst (116).
