Abstract
An exhaust gas treatment system for reducing emissions from an engine includes an exhaust conduit adapted to supply an exhaust stream from an engine to an exhaust treatment device. An injector injects a reagent through an aperture in the conduit into the exhaust stream. A vortex breaker includes a mount having a cylindrical sleeve extending through the aperture as well as a flared tube fixed to and positioned within the cylindrical sleeve. A window extends through an upstream portion of the cylindrical sleeve exposing the flared tube to the exhaust stream. The sleeve includes a downstream aperture in fluid communication with the window.
