Abstract: A reciprocating rotary engine includes a torus-shaped chamber which is divided into two regions. Each divided region forms a sealed chamber. Each sealed chamber is divided by a piston attached to a shaft whereby four sealed chambers are formed. A power converter includes two power combination devices and two motor/generator dual role electric motors. Each combination device has three rotational axes with the torques of two axes being combined together and transferred to the remaining axis. The two electric motors modulate the torque of an axis periodically in accordance with reciprocating rotary motion of the engine, to provide a counterforce to oscillating power and transfer unidirectional torque to a drive shaft.

Abstract: A reciprocating rotary engine of the present invention includes a torus-shaped chamber which is divided into two regions. Each divided region forms a sealed chamber. Also, each sealed chamber is divided by a piston attached to a shaft whereby four sealed chambers are formed. Also, a power converter includes two power combination devices and two motor/generator dual role electric motors. Each combination device has three rotational axes named by A, B and C, as in the case of a planetary gear unit or a differential gear unit. Following this notation, the torques of two axes, A and B are combined together and transferred to the remaining axis C. The two electric motors modulate the torque of B axis periodically in accordance with reciprocating rotary motion of the engine, to thereby provide a counterforce to oscillating power and transfer unidirectional torque to a drive shaft. Namely, the power from the engine can be more effectively converted.
