Abstract
A modular engine design system utilizes selectively replaceable components whereby a family of related engines having varying power outputs may be produced. A first series of engines utilizes a common piston operable in a cylinder of first predetermined dimensions. The engine design may utilize a first or second crankshaft/connecting rod combination to vary the power output. A modified engine design utilizes a second cylinder in addition to the first cylinder. A second series of engines utilizes a larger piston operable in a cylinder of second predetermined dimensions. The second series of engines shares a common engine design scheme with the first series of engines. However, corresponding parts are adapted for use with the larger piston/cylinder combination. The second series of engines may likewise utilize a first or second crankshaft/connecting rod combination to vary the power output.
