The invention concerns a turbo compound system, including a crankshaft driven by an internal combustion engine; a blowdown turbine arranged in the exhaust line of the internal combustion engine; a hydrodynamic clutch, including a driving torus and a driven torus, which form with each other a working chamber that is fillable or filled with working fluid; where 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; and where 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, and where 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.

Turbo-compound system

A turbo-compound system having a crankshaft driven by an internal combustion engine; having an exhaust gas turbine arranged in the flow of exhaust gas of the internal combustion engine; having a hydrodynamic coupling, having a primary impeller and a secondary impeller, together forming a working chamber which may be filled or is filled with a working medium, which is arranged in a driven connection between the crankshaft and the exhaust gas turbine in such a way that, when the working chamber of the hydrodynamic coupling is filled, for the exhaust gas turbine driven by the exhaust-gas flow, drive power is transmitted from the exhaust gas turbine to the crankshaft.

Turbine compound system

The invention relates to a drive unit, comprising an internal combustion engine with a crankshaft; an exhaust line; an exhaust gas turbine which is acted on by the exhaust gas line, which is arranged downstream of the internal combustion engine and has the purpose of transmitting a positive torque to the crankshaft in the traction mode; a hydrodynamic unit which is arranged downstream of the exhaust gas turbine and has two turbine blades which form a torus-shaped working chamber; the hydrodynamic unit has a drive connection to the drive train; and a parking brake is provided for securing the primary turbine wheel of the exhaust gas turbine.
