Abstract (en)
[origin: WO2012110217A1] The invention relates to a drivetrain, in particular motor vehicle drivetrain, having an internal combustion engine which generates an exhaust-gas flow and which has a drive output shaft for transmitting drive power into the drivetrain; - having a turbocharger; - having a turbocompound system comprising an exhaust-gas power turbine which is arranged in the exhaust-gas flow and which is or can be switched into drive connection with the drive output shaft of the internal combustion engine. The invention is characterized in that - the turbocharger is of at least two-stage design and comprises a first turbocharger turbine, which is arranged in the exhaust-gas flow and which drives a first turbocharger compressor arranged in a fresh-air flow conducted to the internal combustion engine, and a second turbocharger turbine, which is arranged downstream of the first turbocharger turbine in the exhaust-gas flow and which drives and a second turbocharger compressor arranged upstream of the first turbocharger compressor in the fresh-air flow; and - the exhaust-gas power turbine of the turbocompound system is arranged in the exhaust-gas flow so as to be parallel, with regard to its throughflow, to the second turbocharger turbine.
