An exhaust manifold apparatus for routing an exhaust gas produced by an internal combustion engine is described. The manifold includes a manifold log with a log wall that defines a log bore. The log bore is in fluid communication with an upstream opening of the manifold log and a downstream opening of the manifold log. An inlet runner includes a runner wall that defines a runner bore in fluid communication with the log bore. The inlet runner is engaged to the manifold log at a stress point, which also includes at least one stiffening rib disposed on an interior surface of the log wall and/or the inlet runner wall.

An exhaust gas purifying apparatus for a vehicle includes: a turbocharger having a turbine which rotates by exhaust gas flowing from an engine into an inlet of the turbine; a filter connected to an outlet of the turbine at an inlet of the filter and allowing the exhaust gas passing through the turbine to flow into the filter; and a gasket disposed between the outlet of the turbine and the inlet of the filter to maintain airtightness between the turbine and the filter. A portion of the gasket is exposed toward the turbine or the filter.

A vehicle exhaust system includes a vehicle body structure, an exhaust system, a rear bumper assembly, an exhaust finisher and a boot. The exhaust assembly is supported to an underside of the vehicle body structure. The rear bumper assembly is also supported to the vehicle body structure. The exhaust finisher is non-movably attached to one of the vehicle body structure and the rear bumper assembly. The exhaust finisher extends at least part way through an opening of the rear bumper assembly. The boot has a first end, a second end, and a flexible portion. The first end is attached to a rear end of the exhaust assembly. The second end is attached to a forward end of the exhaust finisher and the flexible portion extends from the trout end to the second end. The flexible portion is elastically deformable in response to thermal expansion and contraction of the exhaust assembly.

A catalytic reactor including: catalytic cassettes each including a catalyst part configured to reduce NOx in exhaust gas and an outer peripheral part made of a frame covering side surfaces of the catalyst part; and a lattice frame on which the catalytic cassettes are placed. The lattice frame includes a plurality of inflow holes through which exhaust gas flows into the catalyst parts and a plurality of frame parts which defines the respective plurality of inflow holes. The outer peripheral part of each of the catalytic cassettes is positioned so that the outer peripheral part is accommodated in a respective one of the frame parts.

The invention refers to an electrical connection (10) comprising a bushing (12) having a geometric central axis (14), an electrical conductor (16) passing through said bushing (12) along the geometric central axis (14), and an insulating layer (18) electrically insulating said bushing (18) from said conductor (16). It is suggested that the bushing 12, the insulating layer (18) and the electric conductor (16) are pressed together, preferably during a rotary forging process, in order to achieve a mechanical cold transformation.

An exhaust gas treatment arrangement for an exhaust gas system of an internal combustion engine includes a housing which is elongated in the direction of a housing longitudinal axis, and at least one exhaust gas treatment unit which is arranged in the housing and has a shell. At least one bearing/sealing unit with at least two bearing/sealing rings is arranged in a radial intermediate space formed between the shell and the housing. The at least two bearing/sealing rings follow one another radially, are nested inside one another and are each interrupted in a circumferential interruption region. The circumferential interruption region of at least one of the bearing/sealing rings is offset in the circumferential direction with respect to a circumferential interruption region of another one of the bearing/sealing rings.

In one embodiment, there is disclosed an apparatus for decontaminating exhaust gasses. The apparatus includes a monolith catalytic substrate having a length and a width. The substrates length separates first and second opposed ends. The first end and second ends each have a one piece retention ring fitted thereon. The apparatus includes a housing having a length separating opposed, spaced apart open first and second ends. The housing has a side wall extending substantially unbroken there between to define a body having an interior space. The monolith catalytic substrate is disposed in said interior space. The housing has a greater length than said monolith catalytic substrate. The substrate is centered in the housing and the housing is swaged at the first and second ends respectively to engage the retention rings and retain the monolith catalytic substrate within the interior space in said housing.

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.

An exhaust gas treatment assembly comprises a housing which is radially inwardly deformed in a clamping region to retain a block of ceramic or other material which may be arranged as a filter or catalyst within the housing. The clamping region is deformed to a first surface level and includes local protuberances which extend radially outwardly to a second surface level and support a mounting surface for mounting the assembly in a mounting connector. The first surface level may vary to accommodate the dimensions of each individual block while the second surface level is fixed so that the mounting surface can fit in a mounting assembly with standardized dimensions.
