An exhaust turbocharger includes an exhaust control device provided with an exhaust flap for adjusting an exhaust gas flow flowing through a turbine stage of the exhaust turbocharger during the operation thereof, a control gear coupled to the exhaust flap, and a servomotor via which the exhaust flap can be moved in a regulated and/or controlled manner by operation of the control gear at least between a closing position, in which the exhaust flap closes an exhaust gas opening in a turbocharger housing of the turbocharger, through which exhaust gas flows during the operation of the exhaust turbocharger, and at least one other position in which the exhaust flap allows exhaust gas to flow through the exhaust gas opening. The control gear is a self-locking gear via which the exhaust flap can be prestressed in the closing position thereof in relation to the turbocharger housing.

A belt drive arrangement for an internal combustion engine, includes a drive pulley which is driven by a crankshaft of the internal combustion engine, a first output pulley with which a first auxiliary unit can be driven, a second output pulley with which a second auxiliary unit can be driven, and a belt which has an inner face and an outer face opposite the inner face and which loops at least some portions of the drive pulley and the output pulleys as a belt transmission. The inner face of the belt loops the drive pulley and the first output pulley while physically contacting same, and the outer face loops the second output pulley while physically contacting same. An internal combustion engine is provided with such a belt drive arrangement.

Belt drive arrangement

A method and apparatus for welding two or more subcomponents together is described. The subcomponents may be welded to one another along seams, whereby sections of the seam that comprise similar materials are heated to a degree suitable for joining together those particular portions of the seam. Other sections of the seam may be heated to a different degree depending upon the material characteristics employed in that section of the seam. Embodiments of the apparatus include features for holding the subcomponents, simultaneously heating seams of each component, positioning the mating subcomponents together, and applying pressure between mating subcomponents to join them together.

Method and apparatus for welding plastic bodies

A method of producing hollow plastic components, such as for air conduction in internal combustion engines, in which two or more molded or hollow body members are manufactured using injection molding technology, are thereupon brought together and are joined together using plastic welding technology.
