摘要： An exhaust gas purifying apparatus has a first housing including a DOC converter and DPF, and a second housing including an SCR converter, the housings disposed in parallel on the outer side of a frame such that the exhaust upstream ends thereof are positioned on the outer side in the vehicle width direction. An outlet port of the first housing and an inlet port of the second housing are communicatively connected through a communication pipe. The first housing is dividable into a first casing accommodating the DOC converter and a second casing accommodating the DPF, the two casings separably fastened by bolts. The inlet port of the first casing housing is bent inwardly in the width direction and detachably fastened to an exhaust pipe, the distal end of which opens outwardly in the width direction, through bolts. The second casing and housing are fixed to the frame through two brackets.

摘要： An after-treatment system includes a Selective Catalytic Reduction (SCR) catalyst or a similar aftertreatment unit or brick that may be inserted into the opened end of a sleeve. The aftertreatment brick includes a substrate matrix with catalytic material that extends between a first face and a second face. A mantle is disposed around the substrate matrix and extends between a first rim proximate the first face and a second rim proximate the second face. The mantel may include a overhang extension that extends the first rim of the mantle beyond the first face of the substrate matrix. To enable retrieval of the SCR catalyst from the sleeve, a retrieval feature is disposed on a readily accessible, inner surface of the overhang extension.

摘要： A muffler (1) for an exhaust system (2) of an internal combustion engine, especially of a motor vehicle, with a muffler housing (3), which encloses a housing interior space (5), and with at least one exhaust gas-carrying hollow body (4) with two half shells in a half shell construction. The hollow body is arranged in the housing interior space (5). The two half shells (14, 15) of the hollow body (4) are fastened to one another in the area of a separating plane (16). The assembly of the muffler (1) or of the hollow body (4) can be simplified if the two half shells (14, 15) are fastened to one another by fastening elements (17, 18), which are formed directly on the half shells (14, 15).

摘要： A method of producing a metal tubular member that is composed of two or more tube forming bodies and has at least one portion at which the tube forming bodies are superposed on each other, wherein one open annular end section of one of the tube forming bodies, which one annular end section is positioned on the inner side in the superposed section, and the other open annular end section of the other tube forming body, which the other annular end section is positioned on the outer side, are integrally joined by welding. The one annular end section is inserted into the other annular end section with the outside diameter of the one annular end section pressed by a die so as to be smaller in diameter than the inside diameter of the other annular end section, and then pressing force applied to the one annular end section on the inner side is released to cause it to be in tight contact with the inner surface of the other annular end section on the outer side.

摘要： An exhaust device includes an exhaust pipe connected at its upstream end to a cylinder head of the engine and an exhaust muffler connected to the downstream end of the exhaust pipe for suppressing the generation of noise from a heat insulating cover that covers a part of the exhaust pipe. A heat insulating cover covers a portion of the exhaust pipe near the engine and a stay is fixed to the heat insulating cover. The stay includes a supporting plate portion curved so as to partially surround the outer circumference of the exhaust pipe. A first vibration isolating member is provided that is sandwiched between the outer circumference of the exhaust pipe and the supporting plate portion, a band member is tightened to mount the supporting plate portion to the exhaust pipe, and a second vibration isolating member is sandwiched between the supporting plate portion and the band member.
