冷却液流程



图 1g02332698
典型示例
(1) 散热器
(2) 水温调节器和壳体
(3) 水温调节器旁通
(4) 废气冷却器 (NRS)
(5) 缸盖
(6) 缸体
(7) 发动机机油冷却器
(8) 水泵

冷却液由散热器 (1) 底部流到离心式水泵 (8)。 水泵 (8) 安装在定时箱前部。 水泵 (8) 由一个齿轮驱动。 燃油喷油泵的齿轮驱动水泵齿轮。

水泵 (8) 包括一个使用发动机冷却液作为润滑介质的旋转密封。 这将确保形成足够的密封膜。 该密封膜将被保持,以减少热量的产生。 旋转密封表面在正常操作条件下产生的热量导致小流量的冷却液被排放到腔室中。 水泵 (8) 通过正时齿轮箱中的一条通道将冷却液泵送到缸体 (6) 前部。

冷却液进入在缸体 (6 )左侧通道。 一些冷却液会流入缸体中。 部分冷却液流经机油冷却器 (7) 的滤芯。 冷却液随后进入缸体 (6)。 冷却液会绕着气缸的外部流过,然后从缸体流入缸盖 (5) 中。

部分冷却液流过缸盖 (5) 前部的腔室。 部分冷却液通过缸盖 (5) 后部的冷却液管分流到废气冷却器 (4) 中。 随后,冷却液流出废气冷却器 (4),流向缸盖 (5) 中的腔室。

进入水温调节器 (2) 的壳体中。 如果水温调节器 (2) 已关闭,冷却液将直接经旁通道 (3) 流到水泵进口侧。 如果水温调节器开启,旁通水道关闭,冷却液会流到散热器 (1) 的顶部。
