Mixing Device

A mixer assembly comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The tubular housing defines a longitudinal axis along which exhaust enters the housing. The reductant inlet is positioned on a first side of the tubular housing. An upstream elem...

Beschreibung
Zusammenfassung:	A mixer assembly comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The tubular housing defines a longitudinal axis along which exhaust enters the housing. The reductant inlet is positioned on a first side of the tubular housing. An upstream element covers approximately one-half of the cross sectional area of the enhaust gas inlet and is positioned upstream of the reductant inlet. An upstream surface of the upstream mixing element directs exhaust gas flow transversly toward the reductant inlet. A downstream mixing element along with the upstream mixing element at least partially defines a reductant receiving duct in which injected reductant and exhaust gas mix.
