Abstract
This engine relies on a flywheel having a flywheel axis and an undulating cam surface. A piston wit a roller at its base is positioned in a cylinder such that the roller abuts the undulating cam surface at some radial distance from the flywheel axis. Thus, as the piston is pushed downward by combustion pressure in the cylinder, it pushes against the cam surface causing the flywheel to rotate. As the flywheel continues to rotate its undulating surface pushes the piston back into position for a repetition of the cycle. The cam surface can be configured to control engine parameters such as compression ratio, duration of intake stroke, duration of exhaust stroke, duration of combustion stroke, duration of power stroke, compression stroke pattern, volumetric efficiency, or power stroke pattern.
