    • PROBLEM TO BE SOLVED: To provide a technology related to a high-rotation high power type internal combustion engine having superior silence performance, vibration performance and durability, and short-stroked by simultaneously applying a pressure energy generated using the expansion of mixed air combusted in the same combustion chamber on a pair of pistons positioned in a substantially-opposing relation in an inverted V-shape.SOLUTION: This inverted V-shape substantially-opposing engine of the biaxial output type is constituted in such a manner that the pressure energy generated by the expansion of the mixed air combusted in the same combustion chamber is made to simultaneously act on a pair of the pistons having prescribed bank angles (185° to 230°) and positioned in the opposing relation of the inverted V-shape, and rotation power is obtained from the left and right pistons via respective left and right crank mechanisms.

    • PROBLEM TO BE SOLVED: To provide a technique for properly matching a relative rotating phases between both crankshafts when an engine is switched from a cylinder-reduced operation to an all-cylinder operation.
      SOLUTION: This internal combustion engine comprises a power transmission control means cutting off the transmission of power between one crankshaft and an output shaft in the cylinder-reduced operation and releasing the cut-off of the power transmission in the all-cylinder operation. The power transmission control means releases the cut-off of the power transmission by engaging an engaging member rotating together with the output shaft with an engaged member rotating in synchronism with one crankshaft. The relative rotating phase of both crankshafts is set to a predetermined phase by fitting a projected part formed on one of the engaging member and the engaged member to a recessed part formed in the other.

    • PROBLEM TO BE SOLVED: To provide a simple configuration and generate power efficiently, by placing a pair of circulating flow cylinders arranged such that mutual thrusts are facing, arranging a cylinder for supporting point, and exciting circulating flow between the cylinders by equal-pressurizing of each cylinder to generate power. SOLUTION: In operation, a pump 2 is driven by a prime mover 1, and diagonally shaded ahead part in cylinders 9, 10, 11 is brought to the equally pressurized state by turning on an ahead valve 3. At this time, a rack shaft 17 forms a fulcrum using a gear idling shaft 15 as a force-application point, rack shafts 16, 18 exerts the same action as that of a balance by using both edges of a gear 12 as the force-application point, and each rack 15, 17, 18 causes motion with 27 directions. Piston shafts 10, 11 provide relative motion by the action of a differential gear 13, and circulating flow front the piston 10 to the piston 11 is generated. Output form a propeller shaft 19 is transferred to an output shaft 26 through a gear with one-way clutch 21. When the output reaches the ahead end, a sweep back valve 4 is turned on and sweep back motion in the direction 29 is started.
