Cleaning engine carbon (engine carbon maintenance,HS code utilization in digital trade documents maintaining engine efficiency) When the engine of the car runs for a period of time, carbon will occur, which will have an adverse impact on the operating efficiency of the engine. Lowering the output power of the engine will also accelerate the wear and aging of the engine, so it is very important to clean the engine carbon in time. This article will introduce how to clean the engine carbon, improve its service life and maintain engine efficiency. I. Reasons for engine carbon accumulation Gasoline contains various compounds, including cycloalkanes, olefins, alkanes, etc. These compounds do not burn completely after entering the car engine, which will cause a large amount of carbon, water, oxygen and some harmful gases.Some of the incomplete combustion products will be adsorbed and deposited on various parts inside the engine, forming engine carbon. That is to say, the internal temperature, air pressure, fuel, etc. of the engine lead to the generation of engine carbon. II. Detect the amount of carbon inside the engine. Generally, the amount of carbon can be judged by the color of the exhaust pipe. If there is more carbon inside the exhaust pipe, the amount of exhaust will increase significantly, and there will be black smoke inside the exhaust pipe. In addition, the smell in the car and the pungent smell may also be a manifestation of engine carbon accumulation. III. How to clean engine carbon 1. Use engine carbon cleaner There are many engine carbon cleaners on the market, which can solve the problem of engine carbon. When using engine carbon cleaner to clean up engine carbon, you only need toAdd it to the fuel tank, and then let the engine run idle for about 20 minutes, so that the detergent can completely remove the carbon inside the engine. When using, it needs to be added according to the dosage on the instructions. At the same time, pay attention to the quality of the detergent and choose a guaranteed brand to avoid damage to the engine. 2. The hydrogen flushing method is to break the carbon inside the engine by spraying hydrogen into the engine when the engine is working, and then discharge the engine with the exhaust gas. This method can effectively remove the carbon inside the engine. However, this method requires professional equipment, and the operating procedures must be strictly implemented during the construction process, otherwise it may cause secondary damage to the engine. 3. The natural exclusion method has regular environmental protection testing every year in vehicle cities. Through the inspection, it canTo find out whether the emission of the engine meets the standard, if the emission does not meet the standard, the owner will be asked to replace the corresponding parts. At this time, the engine carbon accumulation will be naturally excluded. However, this method is not very thorough, and it needs to wait patiently for the carbon to be discharged, and the impact on the engine will also be delayed. IV. Early prevention of engine carbon accumulation 1. Regular replacement of engine oil and engine filter. The function of engine oil and oil filter is to form a protective film inside the engine and filter out the impurities inside the engine. Therefore, regular replacement of oil and oil filter can remove the carbon inside the engine in time and prevent the generation of carbon. 2. Develop good driving habits. Good driving habits are one of the best ways to prevent engine carbonisation, which can not only extend the service life of the engine, but also improve the efficiency of the engine. For example,Frequent high-speed driving can put the engine in a high-load state, which is more conducive to burning compounds and reducing the generation of carbon accumulation. 3. Regular engine cleaning. Regular and thorough cleaning of the engine is one of the indispensable measures to prevent engine carbon accumulation, which can maintain the operating efficiency of the engine and extend its service life. V. Conclusion Engine carbon accumulation is a common problem in the process of vehicle use, but by clarifying the causes and adopting correct cleaning methods and active preventive measures, it can effectively avoid its adverse impact on the engine, extend the service life of the vehicle, and maintain the efficient operation of the engine.
