Abstract:
A variable geometry mixer for mixing reductant with engine exhaust includes at least one movable mixer blade or set of movable vanes. The variable geometry mixer is operable to extend the mixer blade(s) into the flow of exhaust under low exhaust flow conditions and to retract the mixer blade(s) out of the flow of exhaust under high exhaust flow conditions, or to increase the angle of the movable vanes under low exhaust flow conditions and to decrease the angle of the movable vanes under high exhaust flow conditions. The movable mixer blade(s) may adjoin at least one fixed geometry defining component. Control of the angle or position of the mixer blade(s) or movable vanes may be based on exhaust flow conditions, exhaust temperature, reductant dosing quantity, a particulate filter regeneration event, vehicle information, vehicle engine information, vehicle location, topographical information, and/or environmental information.

Claim (Index 9):
An engine exhaust aftertreatment system, comprising:\n a pipe for conducting a flow of exhaust; a mechanism for introducing reductant into the flow of exhaust; a variable geometry mixer located downstream from the mechanism for mixing the reductant with the flow of exhaust; and a catalytic device located downstream from the variable geometry mixer for causing the reductant to react with the flow of exhaust.
