Abstract:
1. A engine comprising: an engine block housing a cylinder, the cylinder defining a combustion chamber; a pair of opposing pistons slidably disposed within the combustion chamber of the cylinder, each of the pair of opposing pistons slidable between a power stroke position and a compression stroke position to define a cycle of operation, each of said pair of opposing pistons having a piston head disposed within the combustion chamber of the cylinder wherein the piston head of one of the pair of opposing pistons faces the piston head of the other of the pair of opposing pistons, an exhaust port releasing combusted air from the combustion chamber to the environment; at least one internal intake port interconnecting a central cavity of the engine block to the combustion chamber, the internal intake port for providing the combustion chamber with compressed air; an output shaft extending through the central cavity of the engine block and disposed between each of the at least one cylinder; a boost piston cylinder integrally formed at each end of the pair of opposing pistons, the boost piston cylinder having a greater volume than the combustion chamber; a pair of boost pistons each of the pair of boost pistons disposed on distal end of one of the respective pair of opposing pistons, the boost pistons spaced apart from the piston head and disposed within the boost piston cylinder, the boost piston integral to each of the pair of opposing pistons; an external intake port for providing external air to the boost piston cylinder; a central cavity interconnected with the boost piston cylinder; and a boost cylinder port interconnects the boost piston cylinder with the central cavity so as to provide a means for the compressed air to pass from the boost piston cylinder to the central cavity; and a pair of, energy translation mechanisms, one of the pair of energy translation mechanisms mechanically attached to one end of the output shaft, and the other of the pair of energy translation mechanisms mechanically attached to the other end of the output shaft operable to translate the slidable movement of the pair of opposing pistons into rotary motion about the output shaft.
