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.
Claims15
A drive system for an internal combustion engine, comprising:
- a drive gear affixed about a first crankshaft;
- a driven gear affixed about a second crankshaft, wherein the driven gear to engage with the drive gear, and wherein the driven gear to drive, via one or more drive crankshafts, two or more drive rods, wherein the two or more drive rods to drive one or more camshafts via one or more driven crankshafts;
- and
- a pivotal carrier frame to pivot about the first crankshaft, wherein the driven gear and/or at least one of the one or more camshaft drive crankshafts to be rotatably mounted to the pivotal carrier frame such that the driven gear and/or the at least one of the one or more camshaft drive crankshafts to rotate within the pivotal carrier frame as a unit.
