摘要： 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.

The other end portion of the connecting rod and the other end portion of the control rod are linked to each other by a link member rotatably supported on the crankshaft. A rotative power of the crankshaft is transmitted to the camshaft and the rotational shaft, respectively. A timing driving wheel transmitting the rotative power to the camshaft side is mounted on the crankshaft, and a timing driven wheel driven by the timing driving wheel is mounted on the rotational shaft.
