    Abstract: An exhaust aftertreatment system is disclosed. The exhaust aftertreatment system includes a premixer conduit that defines an exhaust flow path, a baffle disposed in the exhaust flow path, and a reductant injector in fluid communication with the exhaust flow path. The baffle is positioned in the premixer conduit, which includes a premixer inlet, a transition section, and a premixer outlet. The transition section is disposed between the premixer inlet and the premixer outlet. The premixer inlet is in fluid communication with the engine. The reductant injector is positioned downstream of the baffle and upstream of the premixer outlet.

    Abstract: A mounting assembly for an injector is located in a curved portion of an exhaust line having an exhaust flow from an upstream end to a downstream end. The mounting assembly includes an indent extending at least partially into the exhaust line curved portion and disposed in the exhaust flow. The downstream wall has an interior surface oriented to substantially face the exhaust line downstream end. A recess extends from the downstream wall in a direction away from the exhaust line downstream end, and a recess aperture is formed in the recess and configured to fluidly communicate with the injector. The recess reduces the amount of exhaust heat reaching the injector tip.

    Abstract: An exhaust system is provided. The exhaust system includes an exhaust conduit having a protuberance thereon. A reductant injector is provided on the protuberance. The reductant injector is positioned such that an ejection tip of the reductant injector is inclined with respect to a centerline of the exhaust conduit. A baffle assembly is coupled to an inner wall of the exhaust conduit. The baffle assembly is positioned upstream of the ejection tip of the reductant injector. A first plate of the baffle assembly is positioned parallel to the centerline of the exhaust conduit. A second plate of the baffle assembly extends from the first plate. The second plate is positioned angularly with respect to the first plate. The baffle assembly is configured to deflect at least a portion of an exhaust gas flow over the ejection tip of the reductant injector.
