摘要： A system and method for the manufacture of a laser-welded cone-shell catalytic converter (100) is provided. An unformed shell blank (111) is formed into a cylindroid shell (110) having overlapping edges (112), which are then resistance welded to produce a shell seam (116). The shell seam (116) is planished to a thickness (120) less than 125 percent of a thickness (119) of the unformed shell blank (111). A ceramic catalytic substrate (130) is wrapped in a ceramic-fiber mounting mat (131) and inserted into the shell (110). Ends (125) of the shell (110) are crimped to form a 1 mm turndown (134). A pair of endcones (140) is assembled, where for each endcone (140) an outer cone (141) is loaded with an endcone insulation (142), and an inner cone (143) is pressed into and spot-welded to the outer cone (141). The endcones (140) are fitted to the shell (110) so as to form an overlap zone (151). The endcones (140) and shell (110) are then laser welded by an Nd:YAG laser (253) in the overlap zone (151).

摘要： By using a spun extrusion method to form a side entry exhaust inlet, a muffler can be completely stuffed and end caps can be spun onto opposing ends of the muffler on a high speed production line without interruptions. The side entry exhaust inlet is formed within a muffler shell at a position between the opposing ends. A spinning tool engages an internal peripheral area of the side entry exhaust inlet to form a spun extruded surface that extends outwardly from the muffler shell.

摘要： A catalytic converter unit includes walls defining a treatment zone, first and second transfer zones and at least one through-flow zone, which zones are adjacent each other. The walls include a partition wall that divides the treatment zone into first and second segments. The first transfer zone is plugged upstream of the partition wall and the second transfer zone is plugged downstream of the partition wall. A catalytic converter element is disposed in the first segment of the treatment zone, spaced from the partition wall. The first segment of the treatment zone is in flow communication with the first transfer zone and the second segment of the treatment zone is in flow communication with the second transfer zone.

摘要： An exhaust silencer allows for elongation of an inner cylinder relative to an outer cylinder. The exhaust silencer is assembled and constructed in such a way as to simplify the assembly process. A rear end portion of the outer cylinder is blocked with a stepped disc. A rear end portion of the inner cylinder is slidably mounted on a step portion of the stepped disc. A fuse portion is provided at the rear end portion of the inner cylinder and is welded to the step portion of the stepped disc. The fuse portion temporarily tacks the stepped disc to the inner cylinder during a temporary assembly stage. The fuse portion is so constructed that it will fracture as a result of thermal expansion of the inner cylinder, when exhaust gas flows through the exhaust silencer.
