Why does oil emulsification increase in winter?
Release date:2024.01.04

Many drivers of the car, in the winter there will be turbidity yellow or white oil emulsification in the oil window, this situation is basically a phenomenon of oil emulsification, oil emulsification phenomenon has slight and serious two situations, slight emulsification refers to a small part of the oil window turbidity, the color is light yellow or white (is also an early warning of emulsification), Severe emulsification means that the oil is all light yellow or white.

The slight emulsification phenomenon is very good to solve, only need to ride normally for a long time, heat up the engine problem to a certain extent (about 90 degrees), the water will gradually volatilize, the emulsification phenomenon will not be intensified, and the oil can be used normally.

When the oil is seriously emulsified (as shown below), it is necessary to immediately replace the new oil (if conditions can be cleaned with a special motorcycle engine cleaning agent), so as to avoid the failure of the oil characteristics after emulsification, resulting in engine failure.


So why does oil emulsification increase in winter? !

As we all know, the composition of oil in addition to the base oil, there will be a variety of additives. Among these additives, oil cleaners and dispersants will cause water to fuse with oil, causing oil emulsification. However, because these two additives are very important, the detergent can prevent carbon particles, glia, dust and metal adhesion, and the dispersant can disperse and suspend oil pollutants in the oil filter for oil filtration, so these two additives must be retained. From this point of view, in order to avoid oil emulsification, the best way is to completely isolate the oil from the water, so where does the water in the engine come from?

Under normal circumstances, the water that causes the oil to emulsify is not from the fluid leakage inside the engine, but from the moisture in the air. Have you all seen dripping water coming out of your car's exhaust? This is because when the air is mixed with gasoline and burned, the water in the air will become high-temperature water vapor and be discharged through the exhaust pipe. When the high-temperature water vapor is cold in the exhaust pipe, it will form water droplets, and finally become the phenomenon of dripping water in the exhaust pipe that we see. Although most of the water vapor formed by the engine during the combustion process will flow out of the exhaust, there will still be a small amount of water vapor to become a fish!

Similarly, when the water vapor in the air enters the crankcase and the motorcycle stops for a night in the winter, the water vapor will condense into water droplets on the cold crankcase wall and mix with the oil to produce emulsification. Many motorcycle air filters are connected to the crankcase balance air pressure tube, and there is a drain hole at the bottom of the general air filter, which is to discharge liquefied water steam and reverse waste oil. However, some inferior motorcycles do not set up this sewage hole, and it is easy to produce serious emulsification in winter. In the face of this phenomenon, you can only change the oil frequently or make a sewage hole.
