DOSING AND MIXING ARRANGEMENT FOR USE IN EXHAUST AFTERTREATMENT

摘要

Dosing and mixing exhaust gas includes directing exhaust gas towards a periphery of a mixing tube (110) that is configured to direct the exhaust gas to flow around and through the mixing tube (110) to effectively mix and dose exhaust gas within a relatively small area. Some mixing tubes (110) include a slotted region (115) and a non-slotted region (116). Some mixing tubes (110) include a louvered region and a non-louvered region. Some mixing tubes (110) are offset within a mixing region of a housing.
