冷却液流量

(1) 散热器

(2) 水泵

(3) 缸体

(4) 发动机机油冷却器

(5) 缸盖

(6) 水温调节器(温控器))和壳体

(7) 水温调节器(温控器)的旁通

冷却液由散热器 (1) 底部流到离心式水泵 (2) 。 水泵 (2) 安装在定时箱前部。 水泵由一个齿轮驱动。 喷油泵齿轮驱动水泵齿轮。 水泵使冷却液从定时箱的通道流至缸体 (3) 的前端。

冷却液进入在缸体 (3) 左侧通道。 部分冷却液进入缸体。 部分冷却液流经机油冷却器 (4) 的滤芯。 冷却液随后进入缸体 (3) 。 流经油缸外围,然后从缸体流至缸盖 (5) 。

冷却液流经缸盖 (5) 。 进入水温调节器 (6) 的壳体中。 如果水温调节器 (6) 已关闭,冷却液将直接经旁通道 (7) 流到水泵进口侧。 如果水温调节器已开启但旁通关闭,则冷却液将流到散热器 (1) 顶部。
