Abstract:
1. A piston engine comprising; first, second, and third planetary gears and a central sun gear that engages the three planetary gears; first, second, and third cylinders, wherein first, second, and third crank throw bearings mount the first, second, and third cylinders to the respective first, second, and third planetary gears in a radial engine configuration, each crank throw bearing comprising a respective first, second, and third crank throw axis that is parallel to and offset from a rotation axis of the respective planetary gear, causing the cylinders to follow a second circular motion; first, second, and third pistons, wherein the three pistons are fixed in radially outward-facing positions on three interconnected connecting rods that are radially oriented in the same plane, the pistons and connecting rods form a piston unit, at least a top surface of each piston remains within a respective cylinder at all times during operation of the engine; and a fourth crank throw bearing that mounts the piston unit to the sun gear on a fourth crank throw axis that is offset from a rotation axis of the sun gear, causing the pistons to follow a first circular motion; wherein the second circular motion is in a courter-circular direction from the first circular motion, and each piston follows a linear motion relative to the respective cylinder.
