ABSTRACT:
Intake and exhaust ports of an internal combustion engine possess respective turbine impellers, and an electrical rotary machine is formed on a rotary shaft connecting the impellers. Sensors are provided for sensing the loaded state of the engine at all times based on engine rpm and the amount of fuel supplied to the engine. When the engine is overloaded, the electrical rotary machine is made to operate as a motor to assist in the supercharging of the engine. When the engine load is not excessive, the rotary machine is made to operate as a generator to charge surplus energy, derived from the engine exhaust, in a storage battery.
