DIESEL EXHAUST FLUID MIXING BODY USING VARIABLE CROSS-SECTION SWITCHBACK ARRANGEMENT
摘要
An aftertreatment system includes a filter configured to receive an exhaust gas and a selective catalytic reduction (SCR) system configured to treat the exhaust gas. A body mixer is disposed downstream of the filter and upstream of the SCR system. The body mixer includes a housing defining an internal volume and including at least a first passageway, a second passageway, and a third passageway. The first passageway receives a flow of the exhaust gas from the filter and directs the flow of the exhaust gas towards the second passageway. The second passageway redirects the flow in a second direction opposite the first direction towards the third passageway. The third passageway redirects the flow in a third direction opposite the second direction towards the SCR system. An injection port is disposed on a sidewall of the housing and configured to communicate an exhaust reductant into the internal volume.
