Engine exhaust pipe injection engine oil (engine exhaust pipe spews black smoke,HS code-driven customs risk scoring car owners need to pay attention) With the development of society, cars have become one of the necessities of people's daily life. However, in daily driving, when the engine exhaust pipe spews black smoke, it often makes the car owners unable to do anything. In fact, this may be caused by the engine exhaust pipe injection oil. At this time, car owners need to pay attention to this signal and repair and maintain it in time. Why do you spray engine oil? First of all, let's take a look at the internal composition of the engine and the oil inside the engine.The road and hydraulic lubrication system is the key to maintaining the normal operation of the engine. It not only ensures the high-speed operation of the engine, but also assumes the protective functions such as reducing the engine temperature, reducing machine wear, and avoiding premature aging of the machine. Engine oil is the main protective agent in the lubrication system in the engine, and timely replacement and maintenance are very important. When the owner does not change the oil for a long time, the oil will lose its original lubrication performance and viscosity due to long-term high temperature and high pressure, and may also produce the phenomenon of glue hardening, which will lead to abnormal operation of the engine, oil leakage or directly lead to engine failure. In this case, the engine runs without oil, which greatly increases the friction and wear of the internal machinery and equipment of the engine, and eventually causes the exhaust pipe to spray black smoke, which is the reason why the engine exhaust pipe injects oil.What should we do? For the oil sprayed by the engine exhaust pipe, the owner must not be careless. The vehicle must be overhauled and maintained in time to avoid more serious consequences. The specific solutions are as follows: 1. Oil replacement: Oil replacement is the most basic way to solve oil leakage. In addition, car owners should develop the habit of changing the oil every certain time to avoid the deterioration and aging of the oil causing the abnormal operation of the machine. Two. Pay attention to the oil level: The oil level is also very important. The oil route designed by some vehicles is relatively complex, which is more likely to produce oil consumption. Regularly check whether the oil level is too low, which helps to keep the oil lubrication system running normally. 3. Maintenance of cylinders and other mechanical equipment: The design of the cylinders of automobile engines is relatively complex, including two cylinders and their moving parts. Regular inspection and maintenance are needed to ensure their normal operation.The owner can detect faults in advance and take corresponding measures by checking the color, noise and smoke of the exhaust pipe. Four. Repair engine failure: If the owner finds that the engine failure is more serious due to oil leakage, he should repair and repair the engine in time to avoid affecting the normal use and safety of the vehicle. In a word, the situation of engine exhaust pipe injection oil needs to be identified and repaired in time. We can't ignore the maintenance and repair of some small details just to save money or effort. Only by checking and repairing frequently can the vehicle be more beautiful and safe in the process of use.
