An internal combustion engine (E) includes a crankshaft ( ), and a bearing cap ( ) supporting the crankshaft ( ) for rotation. Permanent magnets ( ) serving as magnetic field creating members are attached to the balance weights (W to W ) formed integrally with the webs (W to W ) of the crankshaft ( ). Coils ( ) are attached to the bearing cap bodies (A to A ) of the bearing cap ( ). The permanent magnets ( ) and the coils ( ) form electromechanical transducers (M to M ). A small gap can be formed and maintained between the permanent magnets ( ) and the corresponding coils ( ) with reliability without entailing substantial increase in the size of the internal combustion engine. The electromechanical transducers (M to M )are controlled according to the operating mode of the internal combustion engine so as to serve as electric motors or generators.
