Abstract
This engine 1 relies on a flywheel having a flywheel axis and an undulating cam surface. A piston with 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 an explosion 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. More complex embodiments include one in which undulating surfaces are located on opposite faces of the same flywheel with separate pistons interacting with each face and one in which undulating surfaces are located on the facing surfaces of two separate flywheels with pistons positioned between the flywheels. In the latter embodiment, pistons can share the same cylinder.
