Engine deep cleaning - revitalize the vehicle The HS code verification for exportersengine is the main power source of the car, and its working environment is oftenOften bad, it is inevitable to accumulate all kinds of oil scale, carbon and other dirt, resulting in a decrease in engine efficiency, and even directly affecting the performance and life of the car. Therefore, regular deep cleaning of the engine is crucial to ensure the normal operation of the car and extend its service life. I. What is engine deep cleaning? Engine deep cleaning refers to thoroughly cleaning all kinds of dirt inside the engine, removing carbon accumulation, and restoring the normal working state of the engine through mechanical cleaning, chemical cleaning, gas cleaning and other ways. This cleaning method can not only remove oil scale and carbon pollutants inside the engine, but also has a variety of effects such as removing the engine radiator, solving the odor of the air conditioner, and preventing pipeline blockage. II. The necessity of deep cleaning of the engine 1. Improve engine efficiency. There are many pollutants inside the engine, which willParts such as fuel nozzles, high-pressure oil pumps and fuel injectors produce corrosion or deposition, resulting in increased friction between parts. After long-term operation, these sediments will accumulate on the oil and waterways, resulting in the blockage of the heat dissipation system and the blockage of the radiator, resulting in overheating. Deep cleaning of the engine can effectively remove these sediments, improve the efficiency of the engine, and thus improve the performance of the car. Two. Extend the life of the engine. Deep cleaning of the engine can not only effectively improve the efficiency of the engine, but also remove the dirt inside the engine, which can reduce friction, reduce wear and extend the life of the engine. 3. Improve fuel economy. After cleaning the engine, as the dirt inside the engine is removed, the heat of the engine is better released, and the fuel consumption of the vehicle will be reduced accordingly, which can save fuel and also have a more environmentally friendly effect.III. Engine deep cleaning skills 1. Mechanical cleaning Mechanical cleaning is to disassemble the part of the engine to be cleaned, put it in a specific cleaning equipment, and clean it by pressure spray, which can quickly and thoroughly remove carbon, oil scale and other dirt inside the engine. Compared with chemical cleaning, the effect of mechanical cleaning is more thorough, but it also has disadvantages, such as long cleaning time and high labor cost. Two. Chemical cleaning Chemical cleaning is the use of special cleaning agents to clean the engine, which can soften and dissolve various oil scale, carbon accumulation and other dirt inside the engine, effectively remove carbon accumulation, and promote the normal operation of the engine. This method is simple to operate and low-cost, but it cannot completely remove the dirt inside the engine. 3. Gas cleaning Gas cleaning is to use high-pressure gas to spray into the inside of the engine, using airflow impact,Vibration, adsorption and other effects thoroughly clean the carbon, oil scale and other dirt inside the engine, but the cleaning effect of this method is not very significant. IV. Precautions for engine deep cleaning 1. It is forbidden to forcefully start the engine for cleaning, the car engine must be turned off and the battery must be removed to avoid fire and other safety accidents during the cleaning process. In addition, if you encounter dirt that is difficult to clean up during the cleaning process, do not forcefully start the engine to avoid greater danger. Two. Choosing a regular engine cleaning mechanism for engine cleaning is a dangerous operation. Be sure to choose a regular car repair shop or engine cleaning factory to avoid safety problems caused by technical failure to meet the standard. 3. After cleaning, it needs to be tested. After cleaning, the car must be tested and tested to eliminate all hidden dangers and ensure the normal operation of the car.At the same time, you should pay attention to the condition of the car during the driving process, and strengthen the maintenance during the usual use of the car to prevent dirt from accumulating again. In a word, engine deep cleaning is a very important car maintenance operation. Only by keeping the engine clean and in good condition can we ensure the normal use and long life of the car.
