ABSTRACT:
In an internal combustion engine, an improved mechanism for adjusting the rotational axis of the crankshaft to vary the engine compression ratio. The crankshaft is supported at spaced points therealong in circular disks that are swivably adjustable about their central axes. The crankshaft rotational axis is eccentric to the disk axis, whereby disk adjustment moves the crankshaft axis in a direction to vary the engine compression ratio.
