ABSTRACT:
A first exhaust turbo rotary machine is able to assist turbo supercharging by operating as a motor on power generated in a second rotary machine connected to a power axis of an engine. Also, when exhaust energy is large, the first turbo rotary machine operates as a generator so as to make the second rotary machine connected to the engine motive power axis operate electrically, thereby making it possible to add exhaust energy to the engine motive power axis. Consequently, that which results is a compound engine dynamo-electric machine that improves total efficiency of the engine by adding exhaust energy, which is otherwise discarded, to the engine motive power axis. This arrangement increases engine torque in a speed region where exhaust pressure is low by utilizing part of the engine's motive power as a supercharging driving force.
