Abstract
A variable-displacement engine comprises an engine block, cylinders and power shaft. Pistons and connecting rods mounted in the cylinders drive a wobble plate having a rotating ring portion and non-rotating ring portion connected to allow relative rotation therebetween while constraining the portions to remain parallel. The wobble plate defines an inclination plane, pivot axis and wobble plate angle θ. A piston control mechanism (PCM) includes a control yoke rotating with the power shaft and extending to an axially and radially fixed anchor line, a control shaft mounted on the yoke at the control line and a control arm extending from the rotating ring portion and defining a control slot captured over the control shaft. A lift mechanism changes the axial position of the pivot axis, in turn changing, via the PCM, the wobble plate angle θ. This changes the piston displacement of the engine while maintaining a predetermined compression ratio.
