冷却系统图表

冷却液从散热器 (1) 注入水泵 (6) 。 冷却液从水泵流出,然后流过发动机机油冷却器 (7) 。 部分冷却液流至空气压缩机 (4) 和涡轮增压器 (5) ,而大部分冷却液流至缸体 (3) 。

冷却液流入发动机前部的缸体水套中时 和 经由分配歧管被导向发动机缸体两侧。 分配歧管与所有气缸的水套相连接。

冷却液向上流过发动机缸体水套。 冷却液自下而上地流经缸套。 靠近缸套顶端时,水套为锥形,并且冷却套管变小。 该区域温度最高。 更小的面积会提高冷却液流,以便更好地冷却缸套。 来自缸套顶端的冷却液流入气缸盖,将冷却液分配到气缸盖部件周围。 冷却液流到各个气缸盖顶端。 冷却液从缸盖流至缸体。 冷却液经前壳体流至电子控制的水温调节器 (2) 。

水温调节器由温度控制模块控制。 温度控制模块接收来自发动机电子控制模块(ECM)的温度设定点。 当水温调节器开启时,冷却液经由旁通管被送回水泵进口。 当冷却液温度提高时,调节器开启。 调节器开启时,旁通管内的冷却液流动会受到阻力。 冷却液经由出口被发送给散热器。
