An exhaust line element includes an exhaust volume comprising a metal enclosure with a thickness smaller than 1 mm and at least one metal plate with a thickness comprised between 0.5 and 5 mm. The metal plate comprises a central part that does not contact the metal enclosure and between 2 and 4 fastening tabs are secured to the central part. Each fastening tab is spot and transparently welded to the metal enclosure.

An exhaust device includes a supporting component and an exhaust component. The supporting component is configured to support the exhaust component. The supporting component includes a rod and a bracket. The bracket is supported from above by the rod. The exhaust component includes a joining target portion. The joining target portion includes a first joining surface and a second joining surface, to which the bracket is joined. An intermediate surface, which is between the first joining surface and the second joining surface, is provided with a reinforcing portion that reinforces the intermediate surface.

An exhaust system includes a mixer assembly unit (26a) with a mixer body (48a) with an incoming flow side (58a) and with an outflow side (60a) and with a plate shaped carrier element (24a) with a radially outward carrier element body (44a). The mixer body includes a plurality of flow deflection elements (62a) and a holding area (70a). The carrier element includes a counter-holding area (46a) connected in substance to a holding area. The mixer assembly unit is arranged in a junction area of two tubular exhaust gas guide elements (14a, 16a). The exhaust gas guide elements include flange shaped coupling sections. The carrier element body is arranged between the flange shaped coupling sections of the exhaust gas guide elements. A coupling element engages the flange shaped coupling sections and extends over the coupling sections on axial sides oriented facing away from one another radially inwards.

In a manufacturing method of a turbine housing having an exhaust gas flow path, the exhaust gas flow path in the turbine housing is formed of a sheet-metal-made divided body and a cast-metal-made divided body, the sheet-metal-made divided body is formed by press molding a sheet metal material, and the cast-metal-made divided body is molded by casting, when the cast-metal-made divided body is cast, one end of the sheet-metal-made divided body is cast into the cast-metal-made divided body by melting the one end of the sheet-metal-made divided body such that the original shape thereof is disappeared.

A structure is provided for installing a pipe fixing clamp installed in a sound absorber. A part of a curved pipe portion of an internal structural pipe of the sound absorber is cut to form an exhaust gas flow space. The pipe fixing clamp having multiple holes is connected to the exhaust gas flow space.

A heating member for a vehicle exhaust gas purification device includes an electrically conductive outer peripheral frame that has a geometric center and is symmetrical about an axis. An electrically conductive central support is centered on the geometric center, and a perforated heating grid is centered on the geometric center. The heating grid extends between the electrically conductive central support and the electrically conductive outer peripheral frame. The heating grid is formed of a plurality of strands connected by nodes, with the plurality of strands delimiting openings there between.

An after treatment system (ATS) module for a vehicle includes, fluidly connected in series, an inlet, a plurality of chemical reaction modules and an urea mixer module. The chemical reaction modules are arranged to define a substantial quadrangular path of a flow of exhaust gases flowing in the ATS module. The urea mixer module is perpendicular to all the plurality of chemical reaction modules. The ATS module also includes deflector means configured to impart a swirling motion to the flow before flow enters in urea mixer module.

An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a carrier arrangement through which exhaust gas can flow in the direction of an exhaust gas heater longitudinal axis. The exhaust gas heater includes at least one heating conductor supported on the carrier arrangement. The at least one heating conductor is made with bent flat material for the provision of a heating conductor profile which is meandering at least in regions thereof. The heating conductor flat end faces are opposite one another and the heating conductor broad sides are opposite one another.

The present invention relates to an electric heating device (3) in an exhaust gas system (1), having an outer circumferential, in particular circular, housing (4), wherein a rib structure is arranged in the housing (4), which rib structure can be heated by applying an electric current to it. The rib structure is arranged with rib rows (7) parallel to one another in the housing (4), wherein the parallel-arranged rib rows (7) are arranged such that are electrically connected to one another in series or in parallel.

An exhaust pulse balance chamber comprising a circular collar, mid-section that bulges at its center, skirt, and right and left legs, all of which are sealed to the exterior environment and in fluid communication with one another. The outer diameter of the skirt increases in width but not in depth from the proximal end of the skirt to the distal end of the skirt, which is configured to receive the right and left legs. Each leg is bent at a 30-degree angle relative to the central longitudinal axis of the exhaust pulse balance chamber. The invention includes a method of using the exhaust pulse balance chamber to convert a vehicle from a dual-in, single-out exhaust system to a dual-in, dual-out exhaust system.
