Abstract: An axial cylinder variable displacement internal combustion engine. In a first embodiment, variable displacement is provided by a cylindrical sleeve that axially receives the hollow drive shaft of the engine. Plural helical slots are formed in the sleeve. Two of the helical slots slidingly receive opposite ends of a pin that carries a wobble plate and a third slot slidably receives a control pin secured to a control piston that reciprocates in response to changes in inlet manifold pressure. Displacement of the control piston thus effects rotation of the sleeve and a change in the angular and axial orientation of the wobble plate. In a second embodiment, a pair of hydraulically operated cylinders, also responsive to inlet manifold pressure, replace the slotted sleeve but perform the same function.
