Abstract
A vehicle exhaust system includes a mixer and a doser that sprays a reducing agent into the mixer to be thoroughly mixed with engine exhaust gases prior to introduction of the mixture into a downstream exhaust component. The doser is mounted in a tangential orientation relative to a point defined at an intersection of a doser axis with a theoretical cylinder that surrounds a center axis of the mixer and is defined by a variable radius.
