Abstract

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.

付けても同様な効果がある。As shown in Figure 3, a crank (4) is attached to the large end of the Koshirod.
), the crank (6) is attached to the small end as shown in Figure 4.
Even if you attach a crank to the middle of the rod, the same effect will be achieved.

が“のれんに腕押し”のような作用をするからである。The spring (9 or spring σ) is connected to the crank (4
) and crank (6) to rotate smoothly. 'A connecting rod with such a rank also has the effect of reducing vibrations in the work/end. This is because the connecting rod does not directly apply force to the piston or crankshaft, but the crank between the two acts like an ``arm pushing against a curtain.''

It is operated using (13) and lever (14). Therefore,
Trotz is fixed and becomes a conventional engine, and the intake air volume increases, so the exhaust stone remains the same, but high output can be achieved.
