The invention relates to a turbine comprising a turbine housing defining a volute having a substantially annular outlet opening, a turbine wheel, and an adjusting ring, rotatable about the turbine axis, which is arranged in the turbine housing radially between the volute and the turbine wheel, wherein the adjusting ring comprises a flow channel between a radially outer first peripheral opening and a radially inner second peripheral opening, and wherein the outlet opening is fluidically coupled to the turbine wheel by the flow channel. The outlet opening and the first peripheral opening have a path, variable in the axial direction, so that during a rotation of the adjusting ring, the outlet opening and the first peripheral opening are adjusted relative to each other in such a way that an overflow cross section between the outlet opening and the first peripheral opening is variably changeable.

Turbine with adjusting ring

A compressor with a compressor housing in which a compressor wheel is arranged. The compressor additionally includes a cartridge which is arranged in the compressor housing in the area of a compressor inlet. The cartridge is designed to variably change the cross section of the compressor inlet.

Compressor with variable compressor inlet

A turbine housing () of an exhaust-gas turbocharger () having a turbine volute () which is delimited by a metallic outer shell () and which has an inner wall (); and a heat insulation layer () which is arranged on the inner wall () and which has a heat insulation core (A,B) which, on its surface (A,B) facing into a volute interior space (), is covered by a first sheet-metal shell (A,B). The heat insulation core (A,B) is covered, on a surface (A,B,'B) facing toward the inner wall (), by a second sheet-metal shell (A andB respectively).

Exhaust gas turbocharger having an internally insulated turbine volute

The turbocharger according to the invention has a rotor with a compressor wheel as well as a turbine wheel that is connected in a rotationally-fixed manner to the compressor wheel by means of a common shaft. The compressor wheel and the shaft are form-fittingly tensioned with one another, wherein respectively at least one or two torque-transmitting contact surfaces, which lie one atop the other, between components force-fittingly tensioned with one another, is provided with a friction-increasing coating.

Turbocharger with friction-increasing coating

A turbocharger for use in an internal combustion engine has at least one turbocharger housing, at least one compressor situated inside the turbocharger housing, and at least one turbine situated inside the turbocharger housing. In addition, the turbocharger has at least one sensor device for detecting at least a portion of a gas component of an exhaust gas of the internal combustion engine. The sensor device is at least partially integrated into the turbocharger housing.

Turbocharged engine with a sensor device in the turbocharger housing

The present invention relates to a turbocharger () for an internal combustion engine () comprising at least one exhaust gas recirculation line (), via which an exhaust gas mixing opening () enters into an intake line () of the internal combustion engine (), further comprising a turbine () and a compressor (), which is driveably connected to the turbine () and has a compressor impeller () that is disposed in a compressor housing (), into which the intake line () empties via a compressor inlet (), wherein a mixing device () is disposed in the intake line () between the exhaust gas mixing opening () and the compressor inlet ().

Turbocharger with mixing device upstream of compressor inlet

In an exhaust-gas turbocharger with a shaft axially arranged between a compressor wheel and a turbine wheel and connected in a rotationally fixed manner to the compressor wheel as well as to the turbine wheel, said shaft being rotationally mounted with a turbine-side shaft part in a turbine-side bearing, a connecting region with minimal heat conductivity is axially arranged or configured between the turbine-side shaft part and the turbine wheel in such a manner that the heat flow emanating from the turbine wheel is choked.
