ABSTRACT:
The invention is directed to an improved internal combustion engine, having a symmetric cylindrical arrangement and using a bevel gear train to join multiple crankshaft sections. It provides for a naturally smoother operation with less vibration than in-line engines. Better efficiency is expected with the engine than with comparable in-line engines. Manufacturing is expected to be simpler and gasket-sealing better than the in-line and V types of engines. Compactness will add to the engine's utility.
