摘要： Described herein are various embodiments of a reductant decomposition system. According to one representative embodiment, the reductant decomposition system includes an exhaust gas chamber including an inlet and outlet. The system also includes a first exhaust gas distribution component positioned within the chamber and communicable in exhaust gas receiving communication with the outlet. The first exhaust gas distribution component causes swirling exhaust gas flow patterns within the exhaust gas chamber. Additionally, the system includes a second exhaust gas distribution component positioned within the chamber and communicable in exhaust gas providing communication with the inlet. The second exhaust gas distribution component includes features that cause a swirling exhaust gas flow pattern within a space defined by the second exhaust gas distribution component. Further, the system includes a reductant injector coupled to the exhaust gas chamber. The reductant injector is communicable in reductant injecting communication with exhaust gas within the chamber.

摘要翻译： 这里描述的是还原剂分解系统的各种实施方案。 根据一个代表性的实施方案，还原剂分解系统包括包括入口和出口的排气室。 该系统还包括位于室内的第一排气分配组件，并且可与在与出口接收的废气中进行通信。 第一废气分配部件在废气室内引起涡流废气流动模式。 此外，该系统包括位于室内的第二排气分配组件，并且可连通到提供与入口的连通的排气中。 第二排气分配组件包括在由第二废气分配组件限定的空间内引起涡流排气流动模式的特征。 此外，该系统包括耦合到排气室的还原剂注入器。 还原剂注射器可在与室内的废气的还原剂注入连通中进行通信。
