一、发动机机油进水后会有哪些表现呢？

1、 What will happen when the engine oil is flooded?

1.如果车辆的发动机机油进水比较大，那么机油的油面会升高，我们可以观察机油的油尺，一旦机油中含水量过高，那么润滑油的液面就会超出油尺标注的范围。

1. if the engine oil of the vehicle has large water inflow, the oil level of the engine oil will rise. We can observe the oil dipstick. Once the water content in the engine oil is too high, the level of the lubricating oil will exceed the range marked on the dipstick.

2.如果发动机的某些部件损坏，那么发动机冷却液就会进入润滑系统，而这时往往也会在冷却液中发现机油，所以检查发动机冷却液中是否含有机油也是检验机油是否进水的一个方法。

2. if some parts of the engine are damaged, the engine coolant will enter the lubrication system. At this time, engine oil is often found in the coolant. Therefore, checking whether the engine coolant contains engine oil is also a method to check whether the engine oil has water.

3.仔细观察机油的外观状态，也可以看出机油中是否含有水，不含水的机油呈现的是半透明的油质亮色，而含有水的机油会呈现出不透明的褐色或土黄色，如果机油中含有水分，那么发动机运转一段时间后，机油就会出现乳白色。

3. carefully observe the appearance of the engine oil, and you can also see whether the engine oil contains water. The engine oil without water shows a translucent oil color, while the engine oil with water will show an opaque brown or khaki. If the engine oil contains water, the engine oil will appear milky white after the engine has been running for a period of time.

二、机油进水一般是哪些原因造成的呢？

2、 What are the common causes of water ingress in engine oil?

1.机油散热器损坏会导致机油进水，机油散热器损坏，散热器管路发生破损，散热器外部的水会渗透到机油散热器里面，从而导致机油进水。

1. the damage of the oil radiator will cause the oil to enter the water. The oil radiator is damaged, and the radiator pipeline is damaged. The water outside the radiator will penetrate into the oil radiator, resulting in the oil to enter the water.

2.发动机缸套密封圈出现损坏也会导致机油进水。湿式缸套直接与冷却水接触，缸套下部的密封圈可以有效的防止机油和冷却水的渗漏，发动机长时间运行以后，密封圈是很容易失效的，缸套密封圈损坏是机油进水的一个主要原因，所以，在检查机油进水原因的时候，一定要记得检查缸套密封圈是否完好。

2. the engine cylinder liner sealing ring is damaged, which will also cause the engine oil to enter the water. The wet cylinder liner is in direct contact with the cooling water. The sealing ring at the lower part of the cylinder liner can effectively prevent the leakage of oil and cooling water. After the engine runs for a long time, the sealing ring is easy to fail. The damage of the cylinder liner sealing ring is a main reason for the water inflow of the oil. Therefore, when checking the cause of the water inflow of the oil, you must remember to check whether the cylinder liner sealing ring is intact.

3.气缸垫损坏也会导致机油进水，发动机汽缸垫的作用是密封各气缸以及各气缸对应的水道和机油油道，从而避免机油进水，如果气缸垫发生损坏，水循环速度比较快，水道内的水就会流进机油油道，造成机油进水，在每次拆卸完发动机后，一定要使用新的汽缸垫，以免汽缸垫损坏造成机油进水，从而导致发动机损坏。

3. damage to the cylinder gasket will also lead to water ingress of engine oil. The function of the engine cylinder gasket is to seal each cylinder and the corresponding water channel and oil channel of each cylinder, so as to avoid water ingress of engine oil. If the cylinder gasket is damaged and the water circulation speed is relatively fast, the water in the water channel will flow into the oil channel, causing water ingress of engine oil. After each disassembly of the engine, a new cylinder gasket must be used to avoid water ingress of engine oil caused by damage to the cylinder gasket, This will cause engine damage.
