摘要： According to one embodiment, a reductant injection apparatus includes an injector attachment portion to which a reductant injector is coupleable. The apparatus also includes a perforated tubular portion coupled to the injector attachment portion. The perforated tubular portion includes an inlet, an outlet, and a diverging sidewall extending from the inlet to the outlet. Additionally, a plurality of perforations is formed in the sidewall. A reductant spray can be injected into the perforated tubular portion via the inlet. Further, a portion of a bulk exhaust gas stream can be diverted into the perforated tubular portion through the plurality of perforations, through the perforated tubular element, and out of the perforated tubular portion through the plurality of perforations. The portion of exhaust gas stream can then be rejoined with the bulk exhaust gas stream downstream of the perforated tubular portion.

摘要： A reductant decomposition reactor for use in exhaust systems is provided that includes a middle tube portion formed with a reductant injector mount, an inlet tube, an outlet tube and a mixer. The inlet tube is formed at a first end of the middle tube portion and the outlet tube is formed at a second end of the middle tube portion and both are configured to create a sealed connection to different portions of the exhaust system. The mixer fits between the middle tube portion and the outlet tube and is configured to decompose the reductant in an exhaust stream. The injector mount comprises a tube like section that connects at a first end to the middle tube portion and at a second end to an injector port of the injector mount, and is configured to reduce recirculation flow patterns in the reactor, create a high velocity flow at an inner surface of the injector mount and thereby reduce the formation of reductant deposits.
