An exhaust manifold has a head flange constructed for receiving at least two exhaust pipes arranged side-by-side, and includes spaced apart first and second longitudinal flange portions. A mounting assembly is provided for sealingly securing the exhaust manifold to a cylinder head of an internal combustion engine and includes a mounting rail formed with a shoulder which laps over the first longitudinal flange portion and contacts the first longitudinal flange portion in a spring-elastic manner. Plural screw fasteners at least indirectly clamp the second longitudinal flange portion to the cylinder head.

An exhaust-gas turbocharger includes a bearing flange for securement of the exhaust-gas turbocharger to a bearing housing of a turbine wheel. The bearing flange is provided with an outer circumferential fin having a base portion which terminates in a free end. The base portion is defined by a width which is greater than a width of the free end. An outer housing is welded to the outer circumferential fin of the bearing flange, and accommodates an impeller housing.

An exhaust pipe for an internal combustion engine includes an inner tube carrying a flow of exhaust gas and surrounded by an outer tube, with an insulating layer disposed between the inner tube and the outer tube. The inner tube has at least one region formed with a nub-shaped profile in contact with the flow of exhaust gas.

A door frame for motor vehicles includes a window channel laterally defined by an outer door panel and an inner door panel, wherein the outer door panel and the inner door panel are provided adjacent of the window opening with longitudinally extending stiffening or reinforcement members located in the window channel. The reinforcement members are circumferentially closed tubular sections having an essentially oval cross-section, wherein the reinforcement members are adapted in their shape to the inner surfaces of the outer door panel and the inner door panel.

A turbine housing of an exhaust gas turbocharger includes an outer casing and a rotor casing which is arranged in the outer casing and includes a tubular neck for engagement in an exhaust pipe to conduct exhaust gas from the neck in a direction of an exhaust flange. The exhaust pipe is hereby coupled to the rotor casing for relative movement there between. A sealing ring is arranged between the neck and the exhaust pipe, wherein the neck has one end provided with at least one outwardly directed projection defined by an outer diameter which is greater than an inner diameter of the sealing ring. Fabrication of the turbine housing is realized by pushing the sealing ring over the neck, and inserting an expanding mandrel into the neck to widen the neck.

An internal combustion engine (1) includes a pressure wave supercharger (2), wherein the air quantity in a charge air flow produced by the pressure wave supercharger (2) is greater than the air quantity that can be absorbed on average by the internal combustion engine. The internal combustion engine is characterized in that the portion of the charge air flow (7) not absorbed by the internal combustion engine (1) is intended to be supplied to at least one ancillary unit (8, 9, 10, 11) of the internal combustion engine (1) or to at least indirectly cool parts of the internal combustion engine (1).

An exhaust pipe includes first and second length portions, each having an outer pipe and an inner pipe positioned relative to one another to define an annular gap therebetween. The length portions are placed in confronting disposition with their adjacent first ends interconnected for relative movement in a longitudinal direction. An end piece of the outer pipe of the first length portion is disposed in surrounding relationship to an end piece of the outer pipe of the second length portion at interposition of an end portion of the inner pipe of the first length portion, wherein the end pieces of the outer pipes of the first and second length portions and the end portion of the inner pipe of the first length portion are positioned for relative movement in the longitudinal direction, so as to define a triple sliding fit.

A casing assembly for a turbocharger of an internal combustion engine includes a rotor casing having an intake duct and an exhaust flow passage which is connected to an exhaust flange and constructed for attachment to the rotor casing such as to allow a relative movement between the exhaust flow passage and the rotor casing. In this way, a sliding fit is provided which prevents thermal stress in the system rotor casing and exhaust flow passage. An outer housing surrounds the exhaust flow passage, rotor casing and intake duct.
