Abstract: An exhaust device includes a casing including an inlet configured to receive an exhaust gas, an outlet configured to discharge the exhaust gas, and a chamber disposed therein between the inlet and the outlet. The casing defines a longitudinal axis along its length. The exhaust device further includes an exhaust conduit at least partially received within the chamber of the casing along the longitudinal axis. The exhaust conduit includes an inner surface, an opposing outer surface, a plurality of perforations extending through the exhaust conduit from the inner surface to the outer surface, and at least one protrusion extending outwardly from the outer surface. The exhaust device further includes an absorptive material disposed on the outer surface of the exhaust conduit. The at least one protrusion of the exhaust conduit engages with the absorptive material in order to form an interference fit between the absorptive material and the exhaust conduit.

Abstract: A mixer for mixing an exhaust flow in an exhaust pipe includes a tubular housing having a first end, a second end and a center portion positioned between the ends. The center portion has a reduced size in relation to at least one of the first and second ends. The housing includes circumferentially spaced apart apertures extending through the center portion. A mixing element includes a body having a first peripheral portion and a second peripheral portion. The first peripheral portion is fixed to the center portion at a location adjacent to one of the apertures. The second peripheral portion is fixed to the center portion at a location adjacent to another one of the apertures.

Abstract: A mixer for mixing an exhaust flow with a fluid injected into an exhaust pipe includes a tubular housing having a reduced size center portion positioned between first and second ends. The housing includes circumferentially spaced apart apertures extending through the center portion. A first mixing element includes a first peripheral portion positioned within one of the apertures and a second peripheral portion positioned within another one of the apertures. A second mixing element includes third and fourth peripheral portions positioned within other apertures of the housing.
