A multi-layer joint insert is provided at one or more joints between an engine exhaust manifold and a component mounted by fasteners on the exhaust manifold, as well as between the component and the fastener heads/nuts, to reduce wear and failure at the one or more joints. The joint insert includes a first sheet metal layer having at least one fastener-receiving opening and a second sheet metal layer having at least one fastener-receiving opening, wherein the first and second sheet meal layers are joined by at least one connecting arrangement that permits relative sliding movement between the first and second sheet metal layers in response to thermally-induced movement at the one or more joints, thereby reducing wear and failure at the one or more joints.

An exhaust aftertreatment assembly for treating exhaust gas. According to various embodiments, a first housing has a first end and a second housing has a second end, the second end being coupled to the first end. At least one alignment bracket is coupled to the first housing proximate the first end. An annular gasket is supported on the at least one alignment bracket between the first and second ends. The at least one alignment bracket may comprise a base having a curved surface conforming to the interior surface of the housing, the base having a length that is less than a circumference of the interior surface. A stop arm extends substantially transversely from the base. A support arm extends substantially transversely from the stop arm and substantially parallel to the base. An insulation receiving space is defined between the base, stop arm, and support arm.

A mounting assembly for mounting a diesel oxidation catalyst (DOC) system within a work vehicle may generally include a support. bracket having a first side and a second side. The mounting assembly may also include a mount plate configured to be coupled to the first side of the bracket. The mount plate may include first and second plate walls and may define an elongated slot through the first plate wall. Additionally, the assembly may include a retention hand configured to at least partially wrap around a housing of the DOC system between a first end configured to he coupled to the mount plate and a second end configured to be coupled to the second side of the support bracket. The mount plate may be configured to he moved laterally relative to the support bracket to allow the retention band to he tightened and loosened around the housing.

An apparatus compresses a mat against a cylindrical catalyst to provide an exhaust gas cleaning device having the catalyst and the mat wrapped around the catalyst. The apparatus has a base to which first and second rods are movably mounted, and first and second pressers connected to respective ones of the first and second rods. A first drive mechanism moves the first, but not the second, rods to bring the first pressers into contact with first peripheral surface portions of the mat so that second peripheral surface portions of the mat are formed into respective convex portions. A second drive mechanism moves the second rods to bring the second pressers into contact with the convex portions of the mat to compress the convex portions while the first pressers are maintained in pressure contact with the first peripheral surface portions of the mat.

A molded body treating apparatus includes a support, at least one flat plate and a first movement mechanism. The support is configured to support a honeycomb molded body which has a first end portion and a second end portion in a longitudinal direction of the honeycomb molded body and which includes a plurality of cells each extending along the longitudinal direction from a first end at the first end portion to a second end at the second end portion. Either the first end or the second end of each of the plurality of cells is sealed with a plug material paste. The first movement mechanism is configured to move the at least one flat plate along the longitudinal direction to press the either one of the first and second end portions.
