Particulate matter filter assembly with a flow device |
摘要 |
A particulate matter (PM) filter assembly includes a PM filter that filters PM from an exhaust stream and that includes an entry face facing a first direction of flow of the exhaust stream, and a swirl element disposed in the exhaust stream and that includes a blade that directs a portion of the exhaust stream in a second direction of flow that is different than the first direction of flow. The blade directs the portion of the exhaust stream to distribute the exhaust stream over a frontal area of the entry face of the PM filter. A related method of filtering particulate matter from an exhaust stream is also provided. |
