Abstract:
1. Turbo compound system, comprising: a crankshaft driven by an internal combustion engine; a blowdown turbine arranged in an exhaust line of the internal combustion engine; a hydrodynamic clutch, comprising a driving torus and a driven torus, which form with each other a working chamber that is filled or fillable with working fluid; wherein the driven torus of the hydrodynamic clutch is arranged on a shaft on the crankshaft side, which is in drive connection with the crankshaft and is geared up relative to the crankshaft; the driving torus of the hydrodynamic clutch is arranged on a shaft on the blowdown turbine side, which is in drive connection with the blowdown turbine; a rotary pump is arranged on the shaft on the crankshaft side or on the shaft on the blowdown turbine side, whose impeller is driven by this shaft; and the rotary pump is arranged in a common working fluid loop with the hydrodynamic clutch, so that the pump fluid of the rotary pump is the working fluid of the hydrodynamic clutch.
