摘要： An aftertreatment system is provided for reducing particulate matter emission and chemical emissions in diesel engine exhaust gas. The system includes a diesel particulate filter including a plurality of diesel particulate filter units configured to engage respective cross-sectional regions of the diesel engine exhaust gas including particulate matter. Each diesel particulate filter unit includes a plurality of channels aligned in a flow direction of the diesel engine exhaust gas. The channels are selectively configured with a distinct cross-sectional area density. Additionally, each diesel particulate filter unit includes a plurality of walls separating adjacent channels of the plurality of channels, where the walls have a respective thickness. A plurality of pores are configured to vacate a distinct ratio of the area of the walls.
