The device is an internal combustion engine capable of using a variety of fuels which has as its object the increasing of efficiency, power, and torque over conventional designs. The engine includes a reciprocating piston situated inside a cylinder closed at the bottom as well as at the top thereby isolating the combustion process from the crankcase. A piston rod with its wrist pin located inside the crankcase connects the piston to a single offset crankshaft via a connecting rod. The extent of offset on the crankshaft, including one where the crankshaft circumference lies outside of the vertical axis of the piston (the preferred embodiment) determines changes in displacement and in torque. This is achieved by having the piston rod move vertically within the confines of an open-faced bushing situated in the crankcase where the lower end of the piston rod is attached to a connecting rod. The side forces originating from the rotation of the crankshaft are transferred, via the connecting rod, to the piston rod situated inside the crankcase instead of to the piston situated inside the cylinder. This allows for a pancake piston design where compression can take place both on top and below the said piston. By combining this two-sided piston action with a two stroke design, the engine can achieve superior aspiration through piston-charging and the use of a large exhaust valve. Blow-by or leakage is automatically cycled back through the combustion process thereby reducing the potential for contamination. <IMAGE> |
