  • EXHAUST AFTERTREATMENT SYSTEM WITH IN-ELBOW REDUCTANT INJECTION
    Publication number: 20150198073
    Abstract: An exhaust aftertreatment system, such as for a diesel engine, includes a reductant dosing system with an injector positioned in an elbow pipe of an exhaust conduit. A tubeless mixer is positioned in the exhaust conduit between the injector nozzle outlet and an SCR catalyst. The tubeless mixer includes a plurality of rings, all of which are distributed with increasing size as distance from the nozzle outlet increases. The tubeless mixer aides in more uniformly distributing reductant in the exhaust flow prior to arrival at the SCR catalyst.
