标准摘要
[中文适用范围]： 本文件规定了膨胀器/导轨控油环的基本尺寸特征，但没有提供完整的产品描述（因为膨胀器导轨设计因活塞环制造商而异，制造商和客户之间的相互作用将决定具体设计细节）。 本文件适用于公路车辆和其他应用的往复式内燃机的标称直径范围为 40 毫米至 140 毫米的扩径器/导轨控油环。 它也适用于在类似条件下工作的压缩机的活塞环。 [外文原描述]： This document specifies the essential dimensional features of expander/rail oil-control rings, without providing a complete product description (because expander‑rail designs vary from piston-ring manufacturer to piston-ring manufacturer, the interaction between the manufacturer and the client will determine specific design details). This document applies to expander/rail oil-control rings of nominal diameters ranging from 40 mm to 140 mm for reciprocating internal combustion engines for road vehicles and other applications. It also applies to piston rings for compressors working under analogous conditions.
英文名称Internal combustion engines — Piston rings — Expander/rail oil-control rings
