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.
