Cooling System
简介
冷却系统包括以下部件:
- 散热器
- 水泵
- 缸体
- 油冷却器
- 废气冷却器 (NRS)
- 缸盖
- 水温调节器(节温器)

典型示例 (1) 散热器 (2) 水温调节器和壳体 (3) 废气冷却器 (NRS) (4) 缸盖 (5) 缸体 (6) 水泵 (7) 发动机机油冷却器 |
冷却液从散热器 (1) 底部流向发动机机油冷却器 (7) 。 发动机机油冷却器 (7) 安装在发动机右侧。 冷却液从发动机机油冷却器 (7) 流向水泵 (6) 。
水泵 (6) 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。 水泵通过通道向缸体 (5) 中的主冷却液通道泵送冷却液。
冷却液会绕着气缸的外部流过,然后从缸体 (5) 流入缸盖 (4) 中。
冷却液流经缸盖 (4) 。 部分冷却液通过缸体 (5) 右侧的一个冷却液管分流到排气冷却器 (NRS) (3) 中。 随后,冷却液从排气冷却器 (NRS) (3) 流回水温调节器 (2) 的壳体。
进入水温调节器 (2) 的壳体中。 如果水温调节器关闭,冷却液直接经旁通水道流到水泵进口侧。 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。
