An exhaust elbow includes an upstream sidewall defining an upstream portion of the exhaust elbow, a downstream sidewall defining a downstream portion of the exhaust elbow, and a deflector. The upstream portion is configured to receive an upstream exhaust gas. The deflector is coupled to the upstream sidewall of the exhaust elbow upstream and is configured to deflect a portion of the upstream exhaust gas received by the upstream portion of the exhaust elbow away from a region of an interior of the exhaust elbow into which an injected reductant from a dosing module is injected. The deflector may reduce and/or prevent formation of reductant deposits on a downstream sidewall. In some implementations, an exhaust assisted flow separator may also be included to direct a portion of the upstream exhaust gas received by the upstream portion of the exhaust elbow through a dosing opening. 本发明公开了种后处理排气分离器和/或偏转器。排气弯头包括界定排气弯头的上游部分的上游侧壁、界定排气弯头的下游部分的下游侧壁以及偏转器。上游部分配置为接收上游废气。偏转器被联接至排气弯头上游的上游侧壁，并且配置为使由排气弯头的上游部分接收的上游废气的部分远离排气弯头的内
