    摘要: A turbocharger system for an internal combustion engine (10) having at least one exhaust line (15, 16) for evacuating exhaust gases from the combustion chamber (11) of the engine and at least one inlet line (12) for supplying air to the combustion chamber. A high-pressure turbine (17) interacts with a high-pressure compressor (19) and hereupon forms a high-pressure turbo unit (18) with a common rotation axis. A low-pressure turbine (21) interacts with a low-pressure compressor (23) and hereupon forms a low-pressure turbo unit (22) with a common rotation axis, for extracting energy from the exhaust flow of the engine and pressurizing the inlet air of the engine. The low-pressure turbine (21) is of the axial type. The high-pressure turbo unit and the low-pressure turbo unit are serially placed with the rotation axes essentially concentric and with the high-pressure turbine (17) and the low-pressure turbine (21) placed adjacent to each other and coupled together by an intermediate piece configured as a flow duct. This is arranged to allow a certain eccentricity between the two rotation axes. The low-pressure turbo unit (22) is attached to one part of the internal combustion engine (10), while the high-pressure turbo unit (18) is attached to another part of the engine (10).

    摘要: A pipe line for a turbocharger system for an internal combustion engine has at least one exhaust line for the evacuation of exhaust gases from the combustion chamber of the engine to the turbocharger system and at least one inlet line for the supply of air to the combustion chamber. The turbocharger system includes at least one turbine, which cooperates with at least one compressor to extract energy from the exhaust flow of the engine and pressurize the inlet air of the engine. To allow a compact installation with low pressure losses, the inlet line connects with a curved line section of an outlet from the compressor, at least a part-section of the curved line section having a non-circular cross section. A diffuser is placed less than five pipe diameters downstream of the curved line section.
