Abstract: An exhaust system comprises an exhaust driven turbocharger having an outlet and a flanged portion that extends about the outlet, an exhaust treatment device comprising a canister having an inlet cone that includes an integral inlet flange defining an the inlet opening configured to define a seal with the flanged portion that extends about the outlet of the turbocharger and a substrate disposed within the canister through which the exhaust gas flows. An exhaust gas passage, fluidly couples the turbocharger and the exhaust treatment device and allows for the passage of exhaust gas therebetween and a flow modifier comprising a radially inwardly extending wall portion extends from an inner wall of the exhaust gas passage and directs the exhaust gas away from an outer radius of the exhaust gas passage to evenly distribute the exhaust gas across the an inlet face of the substrate.

Abstract: According to one aspect of the invention, a mixer element to be placed between an internal combustion engine exhaust manifold and catalytic converter is provided. The mixer element includes a tubular conduit that receives an exhaust gas flow from the internal combustion engine, a first mixer configured to induce a first vortex of the exhaust gas flow in a first rotational direction and an injector disposed in the tubular conduit downstream of the first mixer, the injector being configured to inject a diesel emission fluid flow into the exhaust gas flow. The mixer element also includes a second mixer positioned downstream of the injector and a third mixer positioned downstream of the second mixer, the third mixer being configured to induce a second vortex of the exhaust gas flow and the diesel emission fluid mixture in a second rotational direction, opposite of the first rotational direction.
