OSTI ID:7077321
This patent describes a process for operating a thermally regenerated reciprocating cyclic internal combustion engine having a rotating power output shaft composed of a number of similar working units, each working unit. It comprises: a cylinder closed at one end by a cylinder head, with a number of intake valves to draw cool fresh air into the cylinder, and with a number of exhaust valves to exhaust the spent combustion gases from the cylinder, the intake valves and exhaust valves communicating with the cylinder portion close to the cylinder head; a first means for opening and closing the intake valves and exhaust valves in a predetermined manner once in each engine cycle; and a piston inside the cylinder moving along the axis of the cylinder in a reciprocating manner toward and away from the cylinder head between the top dead center position closet to the cylinder head and the bottom dead center position furthest away from the cylinder head, the piston being connected by a second means to the power output shaft, where the second means translates the reciprocating motion of the piston to rotation of the power output shaft.
