Turbocharger turbine diffuser with de-swirl ribs

The present disclosure provides a turbocharger turbine diffuser having a de-swirl rib. A turbine diffuser configured for use with a turbocharger is disclosed. The turbine diffuser may include a diffuser wall defining a diffuser and surrounding a central axis of the diffuser; and a plurality of de-swirl ribs, each de-swirl rib extending axially along the diffuser wall. Each de-swirl rib may have afirst end attached to the diffuser wall, and an opposite second end exposed in the interior space of the diffuser. The de-swirl rib may be configured to reduce rotation of the exhaust gas flowing through the diffuser. 本公开提供具有去涡旋肋的涡轮增压器涡轮扩散器。公开了一种配置用于涡轮增压器的涡轮扩散器。涡轮扩散器可包括：扩散器壁，其限定扩散器并围绕扩散器的中心轴线；以及多个去涡旋肋，每个去涡旋肋沿扩散器壁轴向延伸。每个去涡旋肋可以具有附接到扩散器壁的第一端，以及暴露在扩散器的内部空间中的相反的第二端。去涡旋肋可以配置成减少流过扩散器的排气的旋转。
