ABSTRACT:
A complex turbocharger compound engine system has a clutch disposed between the rotatable shaft of a turbine which is drivable by exhaust gases emitted from an engine and a power transmission device by which the rotatable shaft and the output shaft of the engine are operatively coupled to each other, a generator mounted on the rotatable shaft, and a rotary electric machine operatively coupled to the output shaft of the engine and operable selectively as a generator or as a motor. In a region in which the turbine operates with high efficiency, the region depending on operating conditions of the engine, the clutch is engaged to transmit rotative power of the turbine driven by the exhaust gases to the output shaft of the engine, thereby mechanically recovering the exhaust energy of the engine. In a region in which the turbine operates with low efficiency, the generator is driven by the turbine and the rotary electric machine is operated as a motor by the generated electric power. The exhaust energy of the engine is therefore efficiently recovered depending on the operating conditions of the engine.
