Abstract

An exhaust aftertreatment system includes an introduction gas conduit, a dosing module, and a mixer. The introduction conduit is centered on a conduit axis. The dosing module is coupled to the introduction conduit and includes an injector. The injector is configured to provide a hydrocarbon fluid into the introduction conduit and is defined by an injection axis. The mixer includes a mixer body, a first aperture, an injector plate, and an injector cone. The mixer body is disposed within the introduction conduit and is configured to receive exhaust and the hydrocarbon fluid. The first aperture extends through the mixer body and is configured to facilitate flow of the exhaust through the mixer body. The injector plate is coupled to the mixer body along the first aperture. A portion of the injector plate is angled at a first opening angle away from the mixer body. The injector cone is positioned on the injector plate. The injector cone includes an injection aperture configured to facilitate flow of the hydrocarbon fluid through the injector cone and the injector plate.
