Abstract
A variable displacement engine comprises a block having one or more cylinders disposed in parallel around a rotating power shaft. A piston in each cylinder is connected to a connecting rod. A wobble plate, including a first ring, a second ring and a bearing assembly, is mounted on the shaft. The first ring rotates with the shaft and pivots about a pivot axis. The second ring is concentrically adjacent the first ring, has rod bearings connected to each connecting rod, and is connected to the block to prevent relative rotation. The bearing assembly is connected between the rings to allow relative rotation therebetween while constraining the rings to remain parallel. A displacement actuator connected to the wobble plate moves the pivot axis along the shaft to change the displacement, while a piston control linkage changes the wobble plate angle to maintain a constant compression ratio.
