摘要：
A mixer for an exhaust aftertreatment system, such as a diesel engine exhaust aftertreatment system, is disclosed. The mixer includes a body portion that is configured to be disposed in an exhaust conduit upstream of an exhaust aftertreatment device and an airfoil portion that is disposed on the body portion and reversibly movable between a deployed position and a retracted position, wherein in the deployed position the airfoil portion provides a deployed resistance to an exhaust gas flow and in the retracted position provides a retracted resistance, and the deployed resistance is greater than the retracted resistance. The mixer preferably comprises a two-way shape memory alloy, particularly a high temperature, oxidation resistant shape memory alloy. An exhaust aftertreatment system employing the mixer is also disclosed, as well as a method of using the same.
