摘要： The invention relates to a turbocharger system for an internal combustion engine having at least one exhaust line (15, 16) for evacuating exhaust gases from the combustion chamber of the engine and at least on inlet line for supplying air to said combustion chamber. A high-pressure turbine (17) interacts with a high-pressure compressor (19) and a low-pressure turbine (21) interacts with a low-pressure compressor (23) in order to extract energy from the exhaust flow of the engine and pressurize the inlet air of the engine. Both compressor stages are of the radial type and are provided with compressor wheels having backswept blades, in which a blad angle between an imaginary extension of the blade along the centerline between root section and tip section in the direction of the oultel tangent and a line connecting the center axis of the compressor wheel to the outer point of the blade, is at least about 40 degrees. The high-pressure turbine (17) is of the radial type and is connected to the low-pressure turbine by a short intermediate duct (20). The low-pressure turbine (21) is provided with inlet guide rails (34). (Fig. 2)

摘要： The invention relates to 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 said 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), whilst the high-pressure turbo unit (18) is attached to another part of the engine (10).
