点位置交互切換機構。 An eccentric bushing that is fitted between the outside diameter of the crank pin and the inside diameter of the large end of the connecting rod, an external toothed gear that is fixed to this eccentric bushing and whose center hole is fitted into the crankpin; The eccentric bushing includes a ring gear fixedly disposed on the outside and having internal teeth that mesh with the external gear, and the eccentric bush maximizes the amount of eccentricity upward when the piston is at the top dead center of the exhaust stroke. . A top dead center position alternating switching mechanism, characterized in that the ratio of the number of teeth of the external gear to the ring gear is 2:3.
