In a stroke-variable engine, the position of a center of gravity of a subsidiary connecting rod is determined so that a distance between the position of the center of gravity of the subsidiary connecting rod and an axis of a crankpin is smaller than a distance between a point of connection of a main connecting rod to the subsidiary connecting rod and the position of the center of gravity as well as a distance between a point of connection of a control rod to the subsidiary connecting rod and the position of the center of gravity. Thus, 0.5-order vibration generated in the subsidiary connecting rod is lowered, engine vibration is suppressed, and noise generated with the vibration is suppressed.
La présente concerne un moteur à combustion interne à course variable, dans lequel le centre de gravité d'une bielle auxiliaire est positionné de telle façon que la distance entre le centre de gravité de cette bielle auxiliaire et l'axe d'un maneton est plus petite que la distance qui relie la bielle principale à la bielle auxiliaire, et il en va de même de la position du centre de gravité et de la distance qui relie la bielle de commande et la bielle auxiliaire et la position du centre de gravité. Il s'ensuit que la vibration de magnitude 0,5 produite dans la bielle auxiliaire est réduite, la vibration du moteur est supprimée et le bruit causé par la vibration est également atténué.
