Abstract
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.
