Abstract
A mixing assembly for an after-treatment unit of an exhaust system of a vehicle. The mixing assembly includes a swirl component and a bowl. The swirl component has a doser opening on a top surface for the ingress of reductant fluid(s) such as urea. The swirl component has a frustoconical portion and a cylindrical portion. The bowl is extended from a bottom surface of the cylindrical portion. Both the frustoconical portion and cylindrical portion of the swirl component are stamped together or formed from a single sheet metal stamping process. The present mixing assembly can substantially reduce the deposit build-ups in the transition between the swirl component and the bowl.
