摘要: An exhaust gas treatment system of an internal combustion engine includes a selective catalytic reduction catalyst fluidly connected to the internal combustion engine, an oxidation catalyst fluidly connected upstream of the selective catalytic reduction catalyst, and a particulate filter fluidly connected upstream of the selective catalytic reduction catalyst. The exhaust gas treatment system further includes a recirculation line configured to direct a portion of an exhaust flow of the internal combustion engine toward an inlet of the engine.

摘要: An exhaust treatment system includes an oxidation device having a plurality of channels through which a flow of exhaust flows. A first portion of the channels of the oxidation device are coated with catalytic material for converting NO to NO2 and a second portion of the channels are uncoated with the catalytic material. The exhaust treatment system also includes a selective catalytic reduction device disposed downstream from the oxidation device. The selective catalytic reduction device is configured to receive the flow of exhaust passing through the oxidation device.

摘要: An exhaust treatment system for a power system is disclosed. The exhaust treatment system includes an exhaust conduit directing exhaust gas produced by the power system towards at least one exhaust treatment device. The exhaust treatment system may also include a substrate positioned within an enclosure of the at least one exhaust treatment device. The exhaust conduit may be configured to preheat the substrate with the exhaust gas prior to directing the exhaust gas into the enclosure.
