Engine oil mud: How to solve it effectively?HS code intelligence in freight auditingThe engine is one of the core components of the car, and its normal operation directly affects the performance and life of the whole vehicle. In the engine, engine oil plays a lubricating and protective role. However, with the increase of the use time, the engine oil will gradually be polluted to form oil sludge, which will seriously affect the performance of the engine. This article will analyze the problem of engine oil sludge and propose some effective solutions. 1. Understand the problem of engine oil sludge. What is engine oil mud? Engine oil sludge is a gel-like substance produced by impurities and chemical reactions in the oil, which will block the oil line and oil holes, reduce the oil pressure, and cause wear of cylinders, pistons and other parts, thus affecting engine performance and engine life. In automobile use, the formation of engine sludge is related to the following factors: poor oil quality, road surface pollution, urban congestion, low-speed driving, excessive cold start, etc.Therefore, when maintaining the car, it is necessary to know and judge in advance whether there is an engine oil sludge problem. Once a problem occurs, take effective measures as soon as possible to avoid causing greater damage to the vehicle. Two. Adopt effective cleaning methods. For vehicles that have engine sludge problems, the following cleaning methods can be adopted: (1) Chemical cleaning method: by adding cleaning agents and solvents, etc., the oil sludge is completely decomposed, impurities and foreign substances in the oil line are removed, and harmful precipitates such as vinyl are dissolved, so as to achieve the purpose of cleaning the engine. . ( 2) Mechanical cleaning method: Comprehensive mechanical cleaning is carried out by removing the main parts of the engine, such as cylinder head, oil san, etc. This method is thorough and effective, but the operation is complicated, difficult and expensive. ( 3) Ultrasonic cleaning method: This method puts the engine parts into the barrel and removes oil sludge and sediment through ultrasonic vibration. The cleaning effect is very good.The above cleaning methods have their own advantages and disadvantages, and you need to choose the appropriate method for cleaning according to the specific situation. At the same time, in order to avoid the recurrence of oil sludge after cleaning, it is recommended to replace high-quality automobile engine oil and filter elements, and regularly replace the on-board air filter and fuel filter. 3. Develop good driving habits. In order to avoid the generation of engine sludge, in daily use, we can also start from the following aspects: (1) Check before refueling: Check the engine oil volume and details of the vehicle before refueling, so as to avoid oil shortage or the addition of inferior oil, resulting in the generation of oil sludge. ( 2) Normal driving: The car is driving at low speed for a long time or parked for a long time. If the oil temperature is too low, it will lead to oil pollution. You should try not to drive in this situation. ( 3) Avoid frequent cold start-up: The engine wear is large during cold start-up, and short-distance and frequent cold start-up will increase the probability of oil sludge generation.(4) Timely replacement of oil: According to the maintenance cycle stipulated by the manufacturer, the engine oil and filter element of the vehicle should be replaced regularly, which can effectively reduce the generation of engine oil sludge. Four. Conclusion The engine is one of the core parts of the car. How to protect the engine is a problem that every car owner should think about seriously. The occurrence of engine sludge problems will bring a lot of trouble to car owners. Therefore, maintaining good driving habits and regular car cleaning and maintenance have become good habits that car owners must cultivate.
