    摘要: A flow device for an exhaust treatment system includes a base and at least one flow deflector tube secured to the base. The flow deflector tube includes a flow inlet, a flow outlet, and a passage that extends through the flow deflector tube from the flow inlet to the flow outlet. The flow outlet is at an angled orientation to the flow inlet. A method of mixing reactants and exhaust in an exhaust treatment system includes the steps of injecting reactants into exhaust gases flowing through an exhaust conduit used to convey the exhaust gases from an engine. Bent tubes are disposed in the exhaust conduit and used to mix the exhaust gases and the reactants.

    摘要: The present disclosure relates to an exhaust aftertreatment device (30) having a core (18) and an outer housing (40) and a mounting layer (50) positioned between the core (18) and the outer housing (40). The core has an upstream end face (20) and a downstream end face (22). The mounting layer (50) and the housing (40) have main portions (52) that extend from the upstream end face (20) to the downstream end face (22) of the core (18). The mounting layer (50) and the housing (40) also include end portions (40a, 40b) that overlap the end faces of the core (18) to retain the core within the housing (40). The end portions (50a, 50b) of the mounting layer (50) are compressed against the end faces of the core (18) by the end portions (40a, 40b) of the housing (40).
