  • EXTERNAL HEAT ENGINE WITH NON-SINUSOIDAL MOTION
    Publication number: 20210131540
    Abstract: Various embodiments are described herein for methods and devices that relate to a drive mechanism that can be used in an external heat engine to control the motion of the pistons and obtain increased engine power and/or efficiency.
