DIFFUSER IN WASTEGATE TURBINE HOUSINGS

A number of variations may include a turbine housing comprising a turbine body; an inlet passage and an outlet passage connected to the turbine body; a wastegate passage operatively connected to the outlet passage; a diffuser positioned within the outlet passage comprising at least one radial opening; wherein the first flow passage accepts fluid flow from the wastegate passage and the second flowpassage accepts fluid flow from the turbine wheel; wherein a first end of the diffuser is attached to a first end of the turbine outlet and a second end of the diffuser is attached to a second end ofthe turbine outlet so that fluid flow from the first flow passage is directed into the second flow passage through the at least one radial opening before exiting the outlet passage, and wherein the atleast one radial opening minimizes turbulence of fluid flow exiting the turbine housing. 若干变型可包括涡轮机壳体，该涡轮机壳体包括涡轮机主体；连接至该涡轮机主体的入口通道和出口通道；操作性地连接至该出口通道的废气旁通通道；在该出口通道内定位的扩散器，该出口通道包括至少个径向开口；其中，第流动通道接受从该废气旁通通道流动的流体，并且第二流动通道接受从涡轮机叶轮流
