Abstract

System and apparatus are disclosed for reducing reductant deposit formation in an exhaust aftertreatment system. A directing device is provided in the exhaust flow path upstream of a reductant opening into the exhaust flow path. The directing device is configured to direct an exhaust flow toward the reductant opening and around the directing device to effectively mix the exhaust flow with a reductant provided through the reductant opening to reduce the formation of reductant deposits.
