Abstract:
1. An engine comprising: an engine block housing a cylinder, the cylinder defining a combustion chamber and including a boost piston cylinder integrally formed at each end, and the boost piston cylinder having a greater volume than the combustion chamber; a pair 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, each of said pair of opposing pistons further including a boost piston 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; an exhaust port releasing combusted air from the combustion chamber to the environment; a central cavity interconnected with the boost piston cylinder; 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; at least one internal intake port interconnecting the central cavity to each of the combustion chambers, 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 fuel injector assembly disposed within at least one of the pair of pistons, the fuel injector assembly including a fuel injector attached to a conduit, the conduit includes a first tube extending along the length of the piston, the first tube for providing fuel to the combustion chamber, a second tube also extending along the length of the piston and housing the first tube, a fluid control member disposed in both the first and second tube, wherein the fluid control member disposed in the first tube only allows fuel to exit into the combustion chamber, and wherein the fluid control member disposed in the second tube only allows fuel to move away from the combustion chamber, the fuel injector assembly further including a pump, the pump interconnected with the first tube and pumping fuel through the first tube into the combustion chamber, the first tube, second tube, fluid control members and pump working in concert to circulate fuel within the piston; an air control valve, the air control valve fixedly secured to the output shaft and disposed within the central cavity, the air control valve having at least one flange, the at least one flange extending radially from the air control valve to the wall of the central cavity separating the central cavity into partitions, the partitions separating compressed air from atmospheric air, the air control valve rotating within the central cavity in synchronization with the rotation of the output shaft, wherein when the boost pistons slidably move from a power stroke to a compression stroke, external air is provided to the boost piston cylinder by the external intake port, and the air is compressed by the boost piston, and one of the at least one flange rotated about the output shaft so as to be aligned to the opening of the boost cylinder port, wherein the compressed air from the boost piston cylinder is directed into the partition for holding compressed air via the boost cylinder port; and wherein as the output shaft rotates, the partition holding the compressed air within the central cavity is rotatably moved about the output shaft and registered to the internal intake port whereby the compressed air is further directed into the combustion chamber thereby providing low pressure to a defined portion of the central cavity; a pair of energy translation mechanisms, one of the pair of energy translation mechanisms rotatably attached to one end of the output shaft, and the other of the pair of energy translation mechanisms rotatably attached to the other end of the output shaft, each of the pair of energy translation mechanisms including a ring shaped body fittingly enclosing a predetermined portion of the output shaft, the ring shaped body having an arm, the arm attached to each of the boost pistons, each of the pair of energy translation mechanisms including a rotary joint assembly interconnecting each piston to the energy translation member, the rotary joint assembly including a pin case disposed on the free end of each boost piston, the pin case supporting a piston pin, the piston pin extending transversely across the pin case, the rotary joint assembly further including a guide ring disposed on the free end of each arm of each energy translating mechanism, wherein when the pair of opposing pistons slidably move from the compression stroke to the power stroke, one of the pair of opposing piston pushes against the attached arm of the translating mechanism, the arm acting on the ring shaped body the ring shape body being angularly urged against a portion of the output shaft so as to apply a torque onto the output shaft thereby turning the output shaft, thus the translating mechanism translating the slidable movement of the pair of opposing pistons into rotary motion about the output shaft, and wherein when the pair of opposing pistons are operating in the cycle, the guide ring is slidably engaging the piston pin so as to help reduce the effect of the rotary motion of the output shaft on the cyclic operation of the pair of opposing pistons; an energy transforming member attached to the engine block adjacent the output shaft, the energy transforming member being an elongated rigid member having an aperture; a motion control torque reaction device including a ball or rolling element bearing and track or cam surface, the ball bearing disposed between the energy transforming member and the track of the motion control torque reaction device, wherein a portion of the ball bearing is fittingly engaged with the aperture of the energy transforming member, the track defining a predetermined path of travel for the ball bearing, wherein when the pair of opposing pistons complete a cycle of operation, the ball bearing is rotatably positioned underneath the aperture and travels along the predetermined path thereby absorbing rotary motion from energy transforming member so as to reduce side friction of the pistons within combustion chamber; and a port time control system having a shaft phaser controllable by an electronic or mechanical control unit, the shaft phaser disposed on the output shaft and rotatably engaging the energy translation mechanism, wherein the electronic control unit commanding the shaft phaser to rotate the energy translation mechanism so as to offset the position of one of the pair of energy translating mechanisms relative to the other of the pair of energy translating mechanisms.
