摘要： A mixing device of an exhaust gas purification system of an internal combustion engine is disclosed. The mixing device includes swirl tube, a mixing tube arranged in the swirl tube, and an exhaust gas supply tube leading into the swirl tube such that exhaust gas can enter the swirl tube tangentially from the exhaust gas supply tube through a cut-out opening in the lateral surface of the swirl tube and forms a flow rotating around the mixing tube. The exhaust gas completely enters the mixing tube and leaves the interior of the swirl tube completely through the mixing tube. A metering device can spray urea solution into the swirl tube such that the urea solution enters the mixing tube and is entrained by the rotating flow of the exhaust gas and is discharged from the swirl tube through the mixing tube together with the exhaust gas.

摘要： An aftertreatment system comprises a SCR system including at least one catalyst for decomposing constituents of an exhaust gas produced by an engine. An exhaust conduit is fluidly coupled to the SCR system and is structured to deliver the exhaust gas to the SCR system and defines an exhaust conduit opening on a sidewall thereof. A mounting plate is positioned within the opening and includes a plurality of fluid channels. At least one mounting plate opening is defined through the mounting plate downstream of an inlet of the plurality of fluid channels and in fluid communication therewith. The fluid channels are structured to receive and direct at least a pair of exhaust gas streams to a respective opening so that they arrive at the respective opening from different directions. The pair of exhaust gas streams combine with a reductant inserted into the opening before flowing into the exhaust conduit.

摘要： A mixer for a vehicle exhaust system includes a mixer housing defining a mixer central axis and having an inlet at an upstream end and an outlet at a downstream end. An upstream baffle is in the housing at the upstream end and includes at least one inlet opening configured to receive engine exhaust gas. A downstream baffle is in the mixer housing at the downstream end such that the downstream baffle is axially spaced from the upstream baffle. The downstream baffle includes at least one outlet opening. A housing opening is formed within the mixer housing at a location between the upstream and downstream baffles, and which is configured to receive a doser. A cone has a cone outlet opening aligned with the housing opening, and an extension portion extends outwardly from a wide end of the cone to provide a wall that surrounds the cone outlet opening.
