    摘要: A mixing device for mixing a gas and a liquid in an exhaust system has an injector for injecting the liquid, a shell, an inlet, an outlet and an exhaust gas flow path between the inlet and the outlet. The mixing device defines an axis, and the flow path has a first part, a second part and a third part. The first part extends generally parallel to the axis to direct a flow in a generally forward direction, the first part extending up to a first axial position. The second part extends generally parallel to the axis to direct flow in a generally reverse direction. The third part extends generally parallel to the axis to direct a flow in the generally forward direction. The third part is a volume that allows mixing and extends past the first axial position.

    摘要: An apparatus comprises parallel first and second exhaust gas passageways, a urea injection system, a hydrolysis catalyst, and an SCR catalyst. The urea injection system is configured to inject urea into the first exhaust gas passageway. The hydrolysis catalyst is positioned in the first exhaust gas passageway to generate ammonia at least partially from urea injected into the first exhaust gas passageway by the urea injection system. The SCR catalyst is positioned downstream to reduce NOx with the generated ammonia. An associated method is disclosed.
