The invention relates to a turbine casing of an exhaust-gas turbocharger, having an inlet connection piece adjoined by a spiral, and having an outlet connection piece, characterized by an insulating device for reducing the input of heat into the inlet connection piece, the spiral and/or the outlet connection piece.

Turbine casing of an exhaust-gas turbocharger

A multi-stage turbocharger arrangement (TLA), having a high-pressure stage, the high-pressure turbine of which has an associated first bypass valve; and having a low-pressure stage which is arranged downstream as viewed in the flow direction of the exhaust gases and which has a low-pressure turbine and a second bypass valve, wherein at least one of the bypass valves is arranged in an associated, cooled housing module.

Multi-stage turbocharger arrangement

The invention relates to a turbine casing () of an exhaust-gas turbocharger (), having an inlet connection piece () adjoined by a spiral (), and having an outlet connection piece (), characterized by an insulating device () for reducing the input of heat into the inlet connection piece (), the spiral () and/or the outlet connection piece ().

The present invention relates to a multi-stage turbocharger arrangement (), having a high-pressure turbocharger () which has a turbine housing (A), a bearing housing (A), a compressor housing (A); and having a low-pressure turbocharger () which has a turbine housing (B), a bearing housing (B), a compressor housing (B); wherein the turbine housings (A,B) are provided with an integrated inner shell () for conducting exhaust gas.

The present invention relates to a multi-stage turbocharger arrangement (), having a high-pressure turbocharger () which has a turbine housing (A), a bearing housing (A), a compressor housing (A); and having a low-pressure turbocharger () which has a turbine housing (B), a bearing housing (B), a compressor housing (B); wherein the turbine housings (A,B) are combined to form at least one turbine housing unit (), and/or wherein the bearing housings (A,B) are combined to form at least one bearing housing unit (), and/or wherein the compressor housings (A,B) are combined to form at least one compressor housing unit ().
