引起柴油机冷却液减少或油水互窜,不外乎如下7种原因：(1)外漏或蒸发；(2)缸垫损坏；(3)水冷涡轮增压器故障；(4)缸盖或缸体开裂使水道和机油通道互通；(5)机油散热器损坏；(6)缸盖水道开裂使冷却液进入燃烧室；(7)缸体上的水堵松脱造成泄漏。虽然这7种原因有一定的相似处,但故障现象还是各有特点,因而诊断方法也各不相同。 Resulting in diesel engine coolant reduction or oil-water channeling, nothing more than the following seven reasons: (1) leakage or evaporation; (2) cylinder pad damage; (3) water-cooled turbocharger failure; (5) oil radiator damage; (6) cylinder head waterway cracking so that the coolant into the combustion chamber; (7) block on the water block loosening caused by leakage. Although these seven reasons have some similarities, but the symptoms are still different, so the diagnosis method is also different.
