火花塞

[中文适用范围]： 本 SAE 标准仅适用于地面车辆和固定式发动机所用的火花塞。本文件旨在作为大多数当前生产的火花塞和未来应用的通用尺寸指南。本文件的目的并不是禁止制造具有与所提出的尺寸不同的尺寸的火花塞。存在许多需要专用或非标准火花塞的应用。建议尽可能在火花塞设计和发动机应用中使用本文档。每当出现无法使用这些标准火花塞之一的设计情况时，应联系火花塞制造商寻求指导。图1至13和表1A至6显示了非屏蔽和屏蔽火花塞设计的典型配置、它们的尺寸特征、安装、螺纹孔和火花塞螺纹尺寸。 [外文原描述]： This SAE Standard applies only to spark plugs used for ground vehicles and stationary engines.This document is intended to serve as a guide to dimensions common to the majority of current production spark plugs and future applications. It is not the intent of this document to prohibit the manufacture of spark plugs having dimensions differing from those presented. Many applications exist which require specialized or nonstandard spark plugs. It is recommended that this document be used in spark plug design and engine applications wherever possible. Whenever design situations arise that prevent the use of one of these standard spark plugs, a spark plug manufacturer should be contacted for guidance.Figures 1 to 13 and Tables 1A to 6 show typical configurations of unshielded and shielded spark plug designs, their dimensional characteristics, installation, threaded hole, and spark plug thread sizes.Cross Reference:
