Claim:
Apparatus for adjusting a compression ratio of an engine having a crankshaft, at least one combustion cylinder, a moveable piston disposed within the combustion cylinder, and a rod connecting the piston to the crankshaft, said apparatus comprising: a plurality of bearings surrounding said crankshaft at all main bearings, each bearing having an offset bore therethrough supporting said crankshaft, rotational displacement of the bearings causing off axis vertical displacement of said crankshaft along longitudinal axes of said rods thus raising and lowering the crankshaft and connecting pistons without changing a stroke of the piston; means for causing vertical angular displacement of the bearings, said means including offset bushing arms connected to a control shaft through shaft arm levers and lever arm linkages; a control shaft actuator connected to the control shaft by an actuator arm and a throttle linkage, movement of the throttle linkage effecting operation of said actuator.
