An exhaust-gas turbocharger (1) having a turbine housing (2), and having an exhaust manifold (3) connected to the turbine housing (2). At least one adapter ring (4, 5) is arranged between the turbine housing (2) and the exhaust manifold (3).

An exhaust system including: an exhaust pipe including a straight portion, and a bent portion that is bent and extends from a downstream end of the straight portion; a muffler provided on a downstream side of the exhaust pipe; and a reinforcing member, wherein: the straight portion of the exhaust pipe is connected with an upstream end of the muffler through the bent portion; and the reinforcing member is provided so as to extend across a downstream end portion of the straight portion, and an upstream end portion of the muffler.

An exhaust pipe flange with an exhaust gas pipe and with a flange plate fastened to the exhaust gas pipe, wherein the flange plate has an inner side which can be turned toward a cylinder head with a sealing surface which can be placed directly or indirectly against a cylinder head, and a seat in which the exhaust gas pipe is received. The exhaust gas pipe is joined to the flange plate and sealed in the region of the seat on the inner side by a welded connection.

An exhaust gas aftertreatment system for a vehicle includes a cylindrical inner shell, a cylindrical outer shell, an inner end cap, a metal mounting member, and an outer end cap. The inner shell is configured to guide exhaust gas. The outer shell forms a first gap to the inner shell. The inner end cap encloses an open end of the outer shell. The inner end cap includes a first axially-extending lip. The inner end cap is fixed to the inner shell. The outer end cap is fixed to the inner end cap. The outer end cap includes a second axially-extending lip. The outer end cap and the inner end cap cooperate to encapsulate the mounting member. The first axially-extending lip is sandwiched between the outer shell and the second axially-extending lip.

A method for producing an exhaust-gas aftertreatment device inserts a monolith in a housing, assembled from a circumferentially enclosed jacket and two end funnels. The monolith is axially inserted into the jacket with a circumferentially enclosing support mat. The funnels are connected to the jacket via an axial connecting section shaped complementary to the cross-section of the jacket, such that each connecting section and an axial end section of the support mat axially overlap. The jacket, including the connecting sections of the funnels are reduced from a starting cross-section to an end cross-section. This produces a predetermined radial preload in the support mat in a support area extending from the one connecting section to the other connecting section to retain the monolith in the jacket.

A catalyst casing-integrated exhaust manifold (manifold converter) includes an exhaust manifold section and a catalyst casing section. The catalyst casing section includes an approximately cylindrically-shaped casing main body holding a catalyst carrier, a conical part interconnecting the casing main body and the exhaust manifold section, and an outlet side shell connected to a downstream side of the casing main body. The exhaust manifold section and the catalyst casing section are formed by pressing a tailored blank by welding at least two metal blanks different in kind of materials and/or having different in thicknesses. In addition, the exhaust manifold section and the conical part of the catalyst casing section are formed of the same metal blank. The catalyst casing-integrated exhaust manifold and method of manufacturing same can reduce a number of components etc., thereby saving manufacturing cost.

The invention relates to a method for replacing an exhaust aftertreatment component of an exhaust aftertreatment system in a vehicle or vessel. The exhaust aftertreatment system is delimited by an outer casing and comprises a first sleeve, which extends in an axial direction and contains a first exhaust aftertreatment component mounted directly in the first sleeve. The method comprises the steps of: removing the first exhaust aftertreatment component from the first sleeve, the first sleeve thereby remaining intact within the outer casing, providing a second exhaust aftertreatment component being mounted in a second sleeve, the second sleeve being configured to fit within the first sleeve, and mounting the second sleeve with the second exhaust aftertreatment component in the first sleeve by inserting the second sleeve into the first sleeve in the axial direction thereof.

The invention relates to a housing for a selective catalyst reactor for processing exhaust gas from a combustion engine of a combined heat and power system. The housing comprises an annular shaped plate structure forming an elongate accommodation wall defining an inner accommodation volume for containing a catalyst to be flown through by the exhaust gas. The annular shaped plate structure includes a set of plate elements having the same or similar geometry and dimensions.

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.

A heating apparatus for heating fluid includes a container body, a plurality of electric heater elements, and a support structure. The container body defines a perimeter of a flow path for a fluid flowing through the container body. The plurality heater elements are exposed to the flow path. Each heater element includes a resistance element, sheath, and insulating material disposed about the resistance element between the resistance element and the sheath. The support structure includes a plurality of support sheets. The heater elements extend transversely through each support sheet and contact each support sheet to restrict movement of the heater elements and support the heater elements in the container body. The support sheets contact the sheaths of the electric heater elements to increase heat transfer to the fluid flowing through the flow path. Opposite ends of each support sheet are connected to the container body.
