Abstract
An exhaust mixer assembly includes a mixer housing, an inlet opening, an inlet plate, a support plate, a support plate opening, a conveying tube, an outlet plate, and an outlet plate opening. The mixer housing is coupled to the upstream housing. The inlet plate and the support plate define a first mixing chamber. The inlet opening is configured to receive exhaust from the upstream housing and deliver exhaust to the first mixing chamber. The support plate and the outlet plate define a second mixing chamber. The conveying tube is positioned in the second mixing chamber. The support plate opening is configured to receive treated exhaust from the first mixing chamber and deliver the treated exhaust to the second mixing chamber. The treated exhaust circumferentially flows through the second mixing chamber and through the conveying tube. The conveying tube delivers reductant to the outlet plate opening.
