How often should the engine be Precious metals HS code alignmentcleaned (find the engine cleaning time node!) With the increase in the length of car use, the cleaning problem of car engines has attracted more and more attention. The engine is the heart of a car. Its cleaning can not only improve the efficiency of the engine, but also extend its service life. However, many car owners do not know the time node of engine cleaning, which leads to untimely or too frequent cleaning of the engine, and even causing damage to the engine. Therefore, this article aims to discuss the time node of engine cleaning to help car owners better protect car engines. I. What is engine cleaning? Engine cleaning is to clean various components, pipes, oil pipes, intake ducts, etc. in the engine., in order to remove sediments, carbon deposits, impurities and other substances in it, so as to keep the vehicle engine clean, clean and smooth, and reduce the emissions generated by the engine during use. II. Why does the engine need to be cleaned? 1. Protect the engine: During the operation of the engine, long-term use, environmental pollution, fuel quality and other factors may cause the formation of hard and high-viscosity dirt inside the engine components. These dirt will block waterways and oil channels, and even damage the operating system of the engine, causing resonance or vibration. 2. Enhance power: After long-term use, a large amount of carbide accumulates in the engine, which will gradually weaken the function and power of the auxiliary equipment in the cylinder. In order to maintain the best power, economy and reliability, engine cleaning is also essential. 3. Reduce environmental protection emissions: engineWhile the carbon accumulation is serious, long-term use will block the pipelines of the oil line, intake duct and exhaust duct, which will affect the implementation of engine exhaust and emission reduction measures. III. Time node for engine cleaning 1. Long low-speed driving time: Low-speed driving means that vehicles often drive in congested sections such as urban areas. Because this driving mode will cause the engine to run at low speed or idle for a long time, resulting in incomplete combustion, producing a large amount of carbon accumulation, which affects the performance of the engine. Therefore, if the vehicle often drives on low-speed sections, the engine should be cleaned more frequently. 2. Long-term use of the car: If the car is used for a long time, various environmental factors, road conditions, fuel quality, etc. will cause the engine to accumulate a large amount of carbide, which will attach to various parts of the engine, affecting the normal operation and performance of the engine.Therefore, it is recommended to carry out a deep cleaning of the engine every two years. 3. Install a protector: If a protector is not installed in the intake or oil duct of the engine, it is easy to be sucked into impurities, leading to the accumulation of sediment and increasing the resistance of the oil, coolant and intake pipe. Therefore, the protectors should be cleaned and replaced regularly to improve the performance and service life of the engine. IV. There are two commonly used engine cleaning methods for engine cleaning: one is to use professional machines for cleaning, such as glue sprayers, oil injectors and high-pressure injectors; the other is to use chemical cleaning methods. When using the glue sprayer for cleaning, first need to add the specified detergent to the cleaning box of the glue sprayer, and spray the detergent evenly on all parts of the engine. Then let the engine run for a certain period of time, and the cleaning agent circulates inside the engine, so as to achieve the cleaning effect.Chemical cleaning agents can be used to dissolve impurities and sediments in the engine, so as to achieve the purpose of cleaning. V. Summarize engine cleaning is one of the necessary measures to protect the car engine and improve the performance of the vehicle, but the time node of cleaning needs to be determined by the usage and age of the vehicle. It is recommended that the car owner consult the specific cleaning plan of the vehicle to ensure the cleaning effect and safety. At the same time, when using engine cleaners, it is also necessary to pay attention to safety and environmental protection issues, and choose professional institutions and equipment to better protect the car engine.
