ABSTRACT:
A novel engine is provided with a crankshaft that is offset from a centerline of the bore shaft, where a reciprocally sliding piston is disposed. A curved or angularly shaped connecting rod is pivotably connected to the piston at one end and to the crankshaft at the opposite end. The position of the crankshaft and the shape of the connecting rod maximize the travel of the connecting rod through the piston stroke in relation to the overall size of the connecting rod. The design permits maximum compression to be achieved after the top dead center of the crankshaft to further promote engine efficiency.
