REGENERATIVE THERMAL ENGINE An internal combustion engine having a cylinder, a piston reciprocally movable in the cylinder, the cylinder and piston defining in part a chamber for combustion, intake means for introducing air into the cylinder at predetermined intervals, exhaust means for removing combustion gases from the cylinder at predetermined intervals, and a regenerator liner in at least a part of the chamber, the liner having a structure with surfaces defining a plurality of regenerative cells constructed to cyclically admit, hold and discharge compressed air from the cylinder for thermally insulating the cylinder from the heat of combustion, the engine including a mechansim to maintain the piston displaced from the cylinder to avoid contact of the piston with the liner. The preferred engine is a compound rotary and reciprocal engine wherein positive displacement rotary component compresses air in one part for the combined reciprocal piston component and receives exhaust from the reciprocal piston component in another part to drive a rotor in the rotary component.
