Abstract
A mixer assembly comprises a tubular housing including an exhaust gas inlet, an exhaust gas outlet, and a reductant inlet on a side of the tubular housing. An upstream mixing element is positioned within the tubular housing upstream from the reductant inlet. A downstream mixing element is positioned within the tubular housing downstream from the reductant inlet and the upstream mixing element. The upstream and downstream mixing elements at least partially define a reductant receiving mixing chamber in which the injected reductant and exhaust gas mix. A divider is positioned within the tubular housing downstream from the upstream mixing element to split the exhaust into two divided flow streams prior to exiting through the exhaust gas outlet.
