柴油发动机 - 夹紧CR燃油喷射器 - 安装尺寸

[中文适用范围]： 本文件规定了柴油发动机中夹钳安装式共轨燃油喷射器及其对应气缸头特征的尺寸要求。根据喷射器喷嘴螺母帽，夹钳安装式共轨燃油喷射器可分为两种类型：a) A型，喷嘴螺母帽为直筒型（见图4）；b) B型，喷嘴螺母帽为阶梯型（见图5）。每种夹钳安装式共轨燃油喷射器类型又按一系列不同尺寸细分。注：这种区分对应于夹钳安装式共轨燃油喷射器的两个导向直径之间的关系。 [外文原描述]： This document specifies dimensional requirements for clamp mounted CR fuel injectors and their corresponding cylinder head features in diesel engines. According to the injector nozzle capnut, the clamp mounted CR fuel injectors can be divided into two types: Type A, where the nozzle capnut is straight (see Figure 4); Type B, where the nozzle capnut is stepped (see Figure 5). Each clamp mounted CR fuel injector type is subdivided by a series of different sizes. NOTE This differentiation corresponds to the relationship between the two guide diameters of the clamp mounted CR fuel injectors.
