Abstract

An after-treatment exhaust gas mixer for mixing the exhaust gas with a reducing agent, such as a diesel exhaust fluid for selective catalyst reduction, comprises a mixing chamber through which the exhaust gas circulates, from an inlet to an outlet, and a reducing agent sprayer, able to spray a reducing agent into the mixing chamber. The mixing chamber comprises a pipe that is rectilinear along an axis and the sprayer is positioned in the upstream part of the rectilinear pipe and oriented so as to spray in the downstream direction substantially parallel to the axis.
