Plastics (HS code ) import analysis

A brief analysis of the phenomenon and Plastics (HS code ) import analysiscauses of engine oil emulsification The engine is one of the core components of the automobile, and oil, as the "blood" of the engine, is very important for the protection of the engine. However, in long-term use, many car owners will find some annoying problems, that is, oil emulsification. This article willThis problem is analyzed and discussed in detail from the three aspects of the phenomenon, cause and solution of oil emulsification. I. The phenomenon of oil emulsification The phenomenon of oil emulsification refers to the appearance of the milky white liquid formed after the mixture of oil and the water vapor discharged by the engine on the oil liquid surface. When checking the oil, if it is found that the oil has become emulsified, it is necessary to consider whether the oil contains excessive moisture, which is usually caused by the insufficient sealing of the engine. The main manifestations of oil emulsification are: 1. Oil turns white: When too much moisture is sucked into the oil, a large amount of air bubbles will be formed and the oil will turn white. Two. Sediments in the oil area: When the oil is emulsified, the dirt and rust in the oil will form sediment attached to the internal oil system. 3. Oil temperature rises: When the engine is running, the oil will be mixed with water vapor, causing the temperature of the oil to rise.II. Causes of oil emulsification 1. Low-temperature operation: Most oils have a sharp rise in temperature and cooling, especially in cold weather, which will emulsify the oil. Two. Water enters the oil system: If the car is in the water or enters the area of dirty water sedimentation, water may flow into the oil system, resulting in oil emulsification. 3. Long-term idling: Long-term idle operation or frequent round-trip driving may cause oil acidification and pollution, thus causing emulsification. Four. Insufficient engine sealing: The internal sealing of the engine is not good, resulting in the aging or damage of the oil ring, and the oil will evaporate into the condenser and mix with water. 5. Lack of normal maintenance: Long-term lack of normal maintenance, especially the failure to replace the oil for a long time, will lead to oil aging and unclean cleaning, thus leading to emulsification. III. Solve the problem of oil emulsification 1.Change the oil: After checking the engine, if you find that the oil is emulsified, do not let the car continue to run, but immediately replace the oil and oil change filter. Two. Replace the seal: If the internal parts of the engine are found to be damaged or have poor sealing, it is recommended to repair or replace the damaged parts as soon as possible. 3. Regular maintenance: The car needs regular maintenance at any time. Regular oil replacement can avoid oil aging and help prevent emulsification. Four. Post-refueling insurance: Do not refuel at local rivers or water sources, which may mix gasoline or diesel with water and cause oil emulsification. In short, the problem of oil emulsification may cause engine failure, and the emulsified oil cannot protect the engine, especially in winter. Therefore, it is very important to do a good job in the daily maintenance of the car to ensure the smooth operation of the engine.
