Abstract
A turbocharger system for an internal combustion engine having at least one exhaust line for evacuating exhaust gases from the combustion chamber of the engine and at least one inlet line for supplying air to the combustion chamber. A high-pressure turbine interacts with a high-pressure compressor forming a high-pressure turbo unit with a common rotation axis. A low-pressure turbine interacts with a low-pressure compressor forming a low-pressure turbo unit with a common rotation axis. 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 and the low-pressure turbine placed adjacent to each other and coupled together by an intermediate piece configured as a flow duct. The low-pressure turbo unit (22) is attached to one part of the internal combustion engine, while the high-pressure turbo unit is attached to another part of the engine.
