If the gas pressure behind the ring is built up too slowly, and thereby exerts an inadequate outward pressure. In such a case, the combustion gas can penetrate between the liner and ring, and violently force the ring inwards, in the groove. What result will this type of sudden “shock” loading eventually lead to?
参考答案: C
参考解析: 注： 如活塞环后面的气压上升太慢，对外施加压力不足，燃气能够在气缸套与活塞环之间渗过，粗暴地迫使活塞环在槽里向内移动。这种突然的“冲击”负荷最终会导致活塞环断掉。
