    Abstract: An aftertreatment system for treating a high-volume exhaust flow is provided. The aftertreatment system includes a first module having a first mixing element, and a second module having a second mixing element. The aftertreatment system also includes a main inlet conduit, a first inlet conduit, a second inlet conduit, a first outlet conduit, and a second outlet conduit. Each of the first inlet conduit and the second inlet conduit is adapted to split the exhaust flow downstream of the main inlet conduit into a first stream and a second stream flowing therethrough respectively. The splitting of the exhaust flow is adapted to limit a backpressure within the aftertreatment system. Each of the first mixing element and the second mixing element is adapted to improve a mixing of the first stream and the second stream within the first module and the second module respectively.

    Abstract: In one aspect, an exhaust treatment system includes a first particulate filter that has an oxidation catalyst and receives an exhaust stream from an engine. The first particulate filter has a first filter body that defines a plurality of flow-through channels, each open on the inlet and outlet sides of the first filter body. The first filter body also defines a plurality of wall-flow channels, each open on one of the inlet and outlet sides and closed on the other of the inlet and outlet sides. The system also has a second particulate filter that receives the exhaust stream from the first particulate filter. The second particulate filter has a second filter body that defines a plurality of wall-flow channels, each open on one of the inlet and outlet sides of the second particulate filter and closed on the other of the inlet and outlet sides of the second particulate filter.

    Abstract translation: 一方面，废气处理系统包括具有氧化催化剂并接收来自发动机的排气流的第一颗粒过滤器。 第一颗粒过滤器具有限定多个流通通道的第一过滤体，每个通道在第一过滤体的入口侧和出口侧均打开。 第一过滤器主体还限定多个壁流通道，每个通道在入口侧和出口侧之一上开口，并且在入口侧和出口侧的另一个上封闭。 该系统还具有接收来自第一颗粒过滤器的废气流的第二颗粒过滤器。 第二颗粒过滤器具有限定多个壁流通道的第二过滤体，每个壁流通道在第二微粒过滤器的入口侧和出口侧之一上开口，并且在第二微粒过滤器的入口侧和出口侧的另一个上封闭 。
