Abstract
Various embodiments provide for apparatuses and systems involving a reactor pipe configured to receive reductant from an injector into a flow of exhaust exiting an engine. The reactor pipe comprises an inlet portion, a plurality of louvers, an outlet portion, and a radial loop. The inlet portion is structured to receive the flow exiting the engine into the reactor pipe. The louvers are structured to alter a direction of the flow. Further, the radial loop is configured to extend between the inlet portion and the outlet portion and receives the flow of exhaust through the inlet portion. The radial loop also directs the flow of the exhaust toward the outlet portion and reduces the velocity of the flow of the exhaust such that the reductant has an increased amount of time to react with the exhaust.
