PURPOSE:To effectively utilize the energy of exhaust gas and improve the thermal efficiency by elongating an exhaust stroke longer than a suction stroke in the stroke of a piston by constituting the length of a connecting-rod so as to be suitably extended or shortened in a each stroke. CONSTITUTION:A connecting-rod C which connects a crank pin B and a piston A which moves in reciprocation in the cylinder of an internal combustion engine is constituted so as to be extended or shortened with a piston 1 which moves in solidable ways in a cylinder 2. In an intake stroke, the piston A at the top dead center is lowered, after the connecting-rod C is extended to the max. through the revolution of a crank shaft, and intake operation is performed. Then, the piston A at the bottom dead center is raised, after the connecting-rod C is shortened to the min., and compression for the intake gas is performed. Transition to explosion stroke is performed with the contracted state of the connecting-rod C. Then, the piston A at the bottom dead center is raised with the contracted state of the connecting-rod C, and exhaust operation for exhaust gas is carried-out. |
