ABSTRACT:
An internal combustion engine including a working chamber assembly housing, intake and exhaust ports, a pair of piston assemblies each of which assemblies includes at least one pair of diametrically opposed pistons within the working chamber assembly housing rotatable about a rotational axis of said piston assemblies, means for interconnecting said first and second piston assemblies for variable speed rotation in the same direction during recurrent periods of rotation, wherein the piston having a piston head and a piston vessel, the piston head of one piston assembly received by the piston vessel of the other piton assembly to form a working chamber. The connecting means includes a pair of internal gears, a plurality of planetary gears and means for transmitting variable speed rotation, a main transmission gear set, and a pair of auxiliary means that is connected to the piston assemblies.
