Abstract:

(EN)The present invention relates to an apparatus for varying a compression ratio of a mixed gas in a combustion chamber of an internal combustion engine. The apparatus for varying the compression ratio according to the present invention includes: an eccentric member coupled to a crank pin of a crank shaft so that the center of rotation of the eccentric member is eccentric with respect to the center of rotation of the crank pin; a connecting rod of which a lower end is rotatably coupled to the eccentric member, the connecting rod being connected to a piston; and an adjusting unit selectively connected so that the eccentric member and the crank pin or the eccentric member and the connecting rod are integrally rotated with respect to each other to move the center of rotation of the eccentric member with respect to the center of rotation of the crank pin, thereby adjusting the rotational radius in which the lower end of the connecting rod rotates with respect to the center of rotation of the crank shaft.
(FR)La présente invention porte sur un appareil pour modifier un taux de compression d'un gaz mixte dans une chambre de combustion d'un moteur à combustion interne. L'appareil pour modifier le taux de compression selon la présente invention comprend : un élément excentrique couplé à un maneton de telle sorte que le centre de rotation de l'élément excentrique est excentrique par rapport au centre de rotation du maneton ; une bielle dont une extrémité inférieure est couplée de façon rotative à l'élément excentrique, la bielle étant reliée à un piston ; et une unité de réglage reliée sélectivement de telle sorte que l'élément excentrique et le maneton, ou l'élément excentrique et la bielle, sont tournés comme un seul bloc l'un par rapport à l'autre pour déplacer le centre de rotation de l'élément excentrique par rapport au centre de rotation du maneton, réglant ainsi le rayon de rotation avec lequel l'extrémité inférieure de la bielle tourne par rapport au centre de rotation du vilebrequin.
(KO)본 발명은 내연기관의 연소실 내 혼합기의 압축비를 가변시킬 수 있는 압축비 가변장치에 관한 것이다. 본 발명에 따른 압축비 가변장치는 크랭크축의 크랭크핀에 결합되되, 상기 크랭크핀의 회전중심에 대하여 회전중심의 위치가 편심되도록 결합되는 편심부재와, 하단이 상기 편심부재에 회전 가능하게 결합되고 피스톤과 연결되는 커넥팅로드와, 상기 편심부재와 크랭크핀 또는 상기 편심부재와 커넥팅로드가 상호 일체로 회전할 수 있게 선택적으로 결합하여 상기 편심부재의 회전중심을 상기 크랭크핀의 회전중심에 대하여 이동시켜 상기 크랭크축의 회전 중심에 대하여 커넥팅로드의 하단이 회전하는 회전반경을 조절하는 조절유닛을 구비한다.
