EFFICIENT MIXING OF GASES IN AN EXHAUST AFTERTREATMENT SYSTEM

In an exhaust aftertreatment system (110), an inlet (136) for a selective catalytic reduction (SCR) device (120) having SCR catalysts (132, 134) arranged in tandem within a housing (126). The inlet (136) includes a tube (138) extending in an axial direction and offset from the longitudinal axis A of...

Summary:In an exhaust aftertreatment system (110), an inlet (136) for a selective catalytic reduction (SCR) device (120) having SCR catalysts (132, 134) arranged in tandem within a housing (126). The inlet (136) includes a tube (138) extending in an axial direction and offset from the longitudinal axis A of the circular or oval cross section housing (126) of the SCR device (120). A scroll section (146), integral with tube (138), provides an opening (148) which imparts a tangential swirl direction to the gas and DEF mixture entering the SCR device (120).
