Abstract
An exhaust line includes a housing having a wall with an opening and a baffle disposed within the opening. In certain embodiments, the exhaust line includes a divider between the wall and baffle that partially defines a mixing chamber for receiving an exhaust and a reducing agent, and partially defines a bypass chamber for receiving another portion of the exhaust. The divider defines an inlet and outlet facing respective upstream and downstream ends. The divider transfers heat from exhaust passing through the bypass chamber to the reducing agent inside the mixing chamber. In other embodiments, the baffle partially defines a first passageway substantially parallel to and offset from a center axis for delivering a portion of the exhaust to the mixing chamber, and a ramped surface partially defining a second passageway transverse to the first passageway for delivering another portion of the exhaust to the mixing chamber.
