Abstract

PURPOSE:To increase the torque by making the combustion and exhaust strokes longer than the suction and compression stroke when a piston is moving up and down. CONSTITUTION:The lower end of a conrod 1 coupled to a piston is journaled to a crank pin 2 of a crank shaft. A pin 4 for providing the variation onto the stroke is provided retreatably on said crank shaft. Said pin 4 is contacted against a receiving shaft 3 supported in a flywheel 8 of the crank shaft. Consequently the suction and compression strokes can be made different from the combustion and exhaust strokes during the operation of the engine resulting in the increase of the output torque.

る。DETAILED DESCRIPTION OF THE INVENTION In the case of a four-stroke engine, the piston is pulled down during suction, and pushed down during explosion. For this reason, the purpose is to shorten the stroke distance during inhalation, and increase the stroke distance during explosion, thereby creating greater torque with the same C and C, and increasing the horsepower.

面には載せない。In order to make the rotation smooth while changing the stroke distance, we used a crank with 4 pins, 5 springs, and 6 balancing holes. Figure 2, Figure 3, and Figure 4. Figure 2 is a diagram of compression or exhaust top dead center, Figure 3 is a diagram of suction bottom dead center, Figure 4 is a diagram of explosion bottom dead center, and number 2. 3 is a connected conrod bearing shaft, and during suction, 8 rotates along the stopper wheel, but during explosion, it rotates along the conrod. In this way, the piste/vertical distance,
Even if the crank distance is changed, the intake valve and exhaust valve can be the same as in a conventional 4-stroke engine, so they are not shown in the drawings.
