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 16):
The engine exhaust aftertreatment system of  claim 15 , wherein:\n the at least one set of movable vanes further comprises at least one set of upstream movable vanes and at least one set of downstream movable vanes; and the at least one actuator further comprises at least one upstream actuator connected to the at least one set of upstream movable vanes by way of an upstream vane linkage and at least one downstream actuator connected to the at least one set of downstream movable vanes by way of a downstream vane linkage.
