'''活塞环'''(Piston Ring) 是用于嵌入活塞槽沟内部的[[金属]]环，活塞环分为两种：压缩环和机油环。压缩环可用来密封燃烧室内的可燃混合气体；机油环则用来刮除汽缸上多余的机油。

活塞环是一种具有较大向外扩张变形的金属弹性环，它被装配到剖面与其相应的环形槽内。往复和旋转运动的[[活塞环]]，依靠气体或液体的压力差，在环外圆面和气缸以及环和环槽的一个侧面之间形成密封。<ref>[https://www.360kuai.com/pc/93ba5c029927b159b?cota=3&kuai_so=1&sign=360_57c3bbd1&refer_scene=so_1 辉门活塞环——提高效率、降低排放的新型技术],快资讯 , 2019-09-30</ref>
