Abstract: Systems for facilitating conversion between reciprocating linear motion and rotational motion include a continuous undulating track circumscribing a circular profile and generally defining a cylindrical volume having a central axis; a reciprocator that is configured to linearly reciprocate along the central axis; a converter coupled to the reciprocator to reciprocate with it, configured to rotate about the central axis, and engaged with the undulating track; and a rotator engaged with the converter and configured to rotate about the central axis with the converter but not to linearly reciprocate along the central axis.
Abstract: Engines may include a piston, an undulating circumferential track, and a converter. In some examples, engines may include a body, a liner and a rotating cylinder. The body may have a cylindrical interior defining an axis and may include an inlet opening and an exhaust opening. The liner may be mounted within the cylindrical interior. The rotating cylinder may include a port that is sequentially aligned with the inlet and exhaust openings on the body as the rotating cylinder rotates within the body. The piston may be disposed within the rotating cylinder and configured for reciprocating motion along the axis. The converter may be mounted to the piston, engaged with the undulating circumferential track, and configured to reciprocate with the piston. The track may cause the converter to rotate about the axis as the converter reciprocates along the axis. The rotating cylinder may rotate with the converter.

Abstract: Reciprocating engine construction wherein a rotating assembly converts the linear motion of the piston into rotational motion more efficiently, therefore yielding more torque and working power while using less fuel. The rotating assembly is three components working together, an interchanger unit with track rollers mounted at both ends and attached at it's center to the connecting rod by bearings allowing it to rotate while reciprocating, a stationary cylindrical unit having opposing wave shaped races (tracks) encircling it's perimeter with slopes of at least 45 degrees to convert the reciprocating motion to rotational motion on a one to one ratio 90 degrees perpendicular to the axis of the interchanger as the track rollers follow the slopes of the races, a rotating carrier that keeps the track rollers aligned and transfers the converted rotational motion to the output shaft by means of gears.
