Abstract
An example embodiment of an all-stroke-variable internal combustion engine may include a piston slidably positioned within an engine cylinder for asymmetrical reciprocation and a primary crankshaft and a half-speed crankshaft to be operatively engaged for rotation of the half-speed crankshaft at half of a speed of the primary crankshaft, wherein the rotation of the half-speed crankshaft at half of the speed of the primary crankshaft to result in the asymmetrical reciprocation of the piston so as to produce a stroke length that is independently variable over four distinct strokes of a full cycle of the all-stroke-variable internal combustion engine.
