Abstract

A carrier housing for a turbocharger arrangement to be fastened at an internal combustion engine includes first, second and third fastening flanges for fastening to turbines of a respective one of a high-pressure turbocharger, a first low-pressure turbocharger, and a second low-pressure turbocharger. The carrier housing is configured such that exhaust can be guided to the turbines of the high-pressure turbocharger, the first low-pressure turbocharger and the second low-pressure turbocharger via a respective one of the first, second and third fastening flanges. The carrier housing includes at least one connection flange by which the fastening flanges are directly in a fluid-guiding connection, with the connection flange being further connected to an exhaust guidance such that exhaust flows from the internal combustion engine through the first and second connection flanges and directly to the carrier housing.
