Claim:
1. An aftertreatment system, comprising: a selective catalytic reduction system including at least one catalyst for decomposing constituents of an exhaust gas produced by an engine; an exhaust conduit fluidly coupled to the selective catalytic reduction system and structured to deliver the exhaust gas to the selective catalytic reduction system from the engine, the exhaust conduit defining an exhaust conduit opening on a sidewall of the exhaust conduit; and a mounting plate positioned within the exhaust conduit opening, the mounting plate including a plurality of fluid channels defined therein, the plurality of fluid channels positioned within an exhaust gas flow path of the exhaust gas flowing through the exhaust conduit, at least one mounting plate opening defined through the mounting plate, the at least one mounting plate opening in fluid communication with at least a pair of the plurality of fluid channels downstream of an inlet of each of the plurality of fluid channels, wherein each of the plurality of fluid channels are structured to receive and direct at least a pair of exhaust gas streams from the inlet of the plurality of fluid channels to the at least one mounting plate opening so that the at least a pair of exhaust gas streams arrive at the respective mounting plate opening from different directions, the at least a pair of exhaust gas streams combining with a reductant inserted through the at least one mounting plate opening before being inserted into the exhaust gas flow path.
