一种用于排气后处理系统的可重构的双金属混合器及其使用方法
摘要：
本发明涉及一种用于排气后处理系统的可重构的双金属混合器及其使用方法。具体地，本发明揭示了一种用于排气后处理系统的混合器。所述混合器包括被构造来布置在排气后处理系统的排气管道中、并位于排气后处理装置的上游的本体部。混合器还包括布置在本体部上的、在展开位置和缩回位置之间可逆地移动的翼型部，其中翼型部在展开位置提供了对排气流的展开阻力，在缩回位置提供了对排气流的缩回阻力，展开阻力大于缩回阻力，本体部和翼型部一起组成了混合器。混合器进一步包括可操作地连接到混合器的双金属偶，其被构造来从缩回位置向展开位置可逆地移动翼型部。
摘要（英）：

The invention relates a reconfigurable bi-metallic mixer for an exhaust aftertreatment system and method of using the same. The mixer for an exhaust aftertreatment system is disclosed. The mixer includes a body portion that is configured to be disposed in an exhaust conduit of an exhaust aftertreatment system upstream of an exhaust aftertreatment device. The mixer also includes 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 thereto, and the deployed resistance is greater than the retracted resistance, the body portion and airfoil portion comprising a mixer. The mixer further includes a bimetallic couple that is operatively joined to the mixer and configured to reversibly move the airfoil portion from the retracted position to the deployed position.
