Abstract: PURPOSE: A variable compression ratio device is provided to reduce the number of parts by changing the pressure ratio of a cylinder without using oil pressure or an electric motor. CONSTITUTION: A variable compression ratio device comprises an eccentric bearing, a latching rod, a variable slider, a guide plate, and a variable shaft(100). The interior surface of the eccentric bearing contacts the exterior surface of a piston pin while the exterior surface contacts the interior surface of a ring formed on an end of a connecting rod(300). The latching rod is arranged to reciprocate lengthwise in the hollow of the piston pin. The variable slider is arranged in the position to selectively contact both ends of the latching rod and push one side end of the latching rod to the other side. The guide plate supports the variable slider to linearly reciprocate in the direction perpendicular to the longitudinal direction of the latching rod. The variable shaft is connected to the variable slider and rotated to control the sliding direction of the variable slider.

따라서, 하이리프트스윙각을 로우리프트스윙각 보다 크게 할 수 있으므로 로우리프트 작동 상태에서 리턴스프링에 의한 마찰 손실에 따른 연비 저하가 방지되고, 로스트모션각을 최적 조건으로 감소시킬 수 있으므로 CVVL 구현이 용이하게 이루어지며, 로스트모션각 감소에도 불구하고 진각 효과가 확실하게 발생할 수 있게 되는 효과가 있다.
