Zusammenfassung:	An exhaust aftertreatment system is disclosed. The exhaust aftertreatment system includes a premixer conduit that defines an exhaust flow path, a baffle disposed in the exhaust flow path, and a reductant injector in fluid communication with the exhaust flow path. The baffle is positioned in the premixer conduit, which includes a premixer inlet, a transition section, and a premixer outlet. The transition section is disposed between the premixer inlet and the premixer outlet. The premixer inlet is in fluid communication with the engine. The reductant injector is positioned downstream of the baffle and upstream of the premixer outlet.
