Abstract: An exhaust aftertreatment module is provided. The exhaust aftertreatment module includes a housing having a first end and a second end. The at least one inlet is disposed between the first end and the second end and is configured to introduce an exhaust into the housing. A mixing tube is disposed downstream of the at least one inlet. The mixing tube is configured to direct the exhaust towards the second end of the housing. The exhaust aftertreatment module further includes a single bank of Selective Catalytic Reduction (SCR) catalysts disposed at an oblique angle to a longitudinal axis of the mixing tube. The single bank of SCR catalysts is configured to receive the exhaust redirected from the second end of the housing.
Abstract translation: 提供排气后处理模块。 排气后处理模块包括具有第一端和第二端的壳体。 至少一个入口设置在第一端和第二端之间，并且构造成将排气引入壳体。 混合管设置在至少一个入口的下游。 混合管构造成将排气引导到壳体的第二端。 排气后处理模块还包括以与混合管的纵向轴线成倾斜角度设置的单组选择性催化还原（SCR）催化剂。 单组SCR催化剂构造成接收从壳体的第二端重新定向的排气。

Abstract: An aftertreatment module is disclosed for use with an engine. The aftertreatment module may have an inlet housing at least partially defining an inlet passage for exhaust, and at least one mixer disposed in the inlet passage. The aftertreatment module may also have an outlet housing at least partially defining an outlet passage for exhaust, and a catalyst housing removably connected between the inlet housing and the outlet housing. The aftertreatment module may further have a plurality of catalyst substrates configured to be mounted in the catalyst housing, to receive exhaust from the inlet passage in parallel, and to discharge exhaust to the outlet housing in parallel.

Abstract: A system for assembling an exhaust after-treatment assembly having a plurality of exhaust after-treatment blocks is described. Each of the plurality of exhaust after-treatment blocks is disposed adjacent to at least one other exhaust after-treatment block. Each exhaust after-treatment block has one or more catalyst substrates. Each catalyst substrate includes a first face, a second face, and a plurality of side faces. The system includes at least one flange member to surround the one or more catalyst substrates about the side faces. The system further includes a locking arrangement including one or more clips on the flange member and a bracket member configured to engage with the one or more clips in the flange members of the adjacent exhaust after-treatment blocks.
