Abstract: A component for a vehicular exhaust pipe includes an upstream venturi forming portion for creating at least a partial vacuum interior to the component. A downstream diverter housing portion of the component has an inlet coupled to an outlet of the venturi portion. The diverter housing portion includes the diverter element positioned adjacent an output of the diverter housing portion for forcing axially central exhaust flow radially outward toward a wall of the diverter housing. The partial vacuum in the component device causes colder environmental ambient air to enter an inlet of the component. The diverter also creates a mixture of hot exhaust flow with the colder environmental air, resulting in a lower temperature of the exhaust gas exiting the component and substantial elimination of centrally disposed exhaust hot spots.

Abstract translation: 用于车辆排气管的部件包括用于向部件产生至少部分真空内部的上游文丘里形成部分。 部件的下游分流器容纳部分具有联接到文氏管部分的出口的入口。 分流器壳体部分包括位于分接器壳体部分的输出附近的分流器元件，用于迫使轴向中心排气流径向向外朝向分流器壳体的壁。 部件装置中的部分真空使较冷的环境空气进入部件的入口。 分流器还产生热排气与较冷的环境空气的混合物，导致排出组件的废气的温度较低，并且基本上消除了集中设置的排气热点。
