<p>PROBLEM TO BE SOLVED: To effectively utilize torque fluctuations generated by reciprocation mass of a piston, etc. to increase the output torque.SOLUTION: A reciprocal engine 10 includes: a crank shaft 11 rotated by reciprocating-motion of a piston; a fly wheel 12 disposed in the crank shaft 11; and a one-way clutch 13 which is provided between the crank shaft 11 and the fly wheel 12 and transmits only rotation torque of the crank shaft 11 in a forward direction to the fly wheel 12.</p> |
