An internal combustion engine, in particular gas engine, with multiple cylinders, wherein in the cylinders a mixture of charge air and a gaseous fuel can be combusted, with a first turbocharger, in which exclusively the charge air can be compressed, and with a second turbocharger, in which exclusively the gaseous fuel can be compressed.

Internal combustion engine, turbocharger for an internal combustion engine and method for operating the internal combustion engine

A turbocharger, has a turbine for expanding a first medium and a compressor for compressing a second medium. The turbine includes a turbine housing and a turbine rotor. The compressor includes a compressor housing and a compressor rotor coupled to the turbine rotor via a shaft. A bearing housing is arranged between the compressor and turbine housings in which the shaft is mounted. The turbine and bearing housings are connected via a fastening device mounted on a flange of the turbine housing with a first section and a second section that covers a flange of the bearing housing at least in sections. The fastening device is contoured curved on a surface of the second section facing the flange of the bearing housing.

Turbocharger

A turbo compressor of an exhaust gas recirculation of an internal combustion engine, with a compressor housing, a compressor rotor, a shaft that is coupled to the compressor rotor and mounted in the compressor housing, a piston ring seal to prevent an exhaust gas blow-by flow in the direction of bearings, and a labyrinth seal, which seen in the direction of the exhaust gas blow-by flow, is positioned upstream of the piston ring seal.

Turbo compressor

A method for working a housing of a turbocharger, namely a bearing housing or a compressor housing or a turbine housing of the turbocharger has the following steps: providing the housing to be worked, filling at least one hollow space of the housing to be worked with an incompressible fluid; and building-up a fluid pressure in the respective hollow space filled with the incompressible fluid, at least locally deforming plastically a housing portion of the housing limiting the respective hollow space of the housing at least in portions.
