摘要: Methods and systems for treating NOx-containing exhaust from an internal combustion engine. An aftertreatment system has at least a primary oxidation catalyst, particulate filter, selective reduction catalyst (SCR). A bypass line diverts portion of the point downstream filter to upstream SCR. secondary on is used generate NO or NO2 be returned
