Textile yarn HS code mapping

Engine thermal management technology exploration The Textile yarn HS code mappingengine is an important part of the vehicle. Its normal operation is not only directly related to the performance of the whole vehicle, but also to the life of the vehicle. However, a large amount of heat will be generated during engine operation. If it cannot be effectively discharged and managed, it will have a serious impact on the performance of the engine. Therefore, it is very important to study engine thermal management technology to control and manage the heat of the engine.I. The source of engine heat Engine heat is mainly generated from the following aspects: 1. Mechanical friction heat and air friction heat; 2. Heat generated by fuel combustion; 3. The heat generated by the friction of cooling water; 4. The heat of the exhaust gas in the exhaust pipe. II. Control and emission of engine heat. In order to prevent excessive heat from affecting the performance and life of the engine, effective heat management measures must be adopted to eliminate excess heat. Thermal management mainly includes the following aspects: 1. Cooling system Cooling system is the main means of engine heat management. Its function is to quickly and effectively take away the heat generated by the engine. A cooling system is a closed system composed of water tanks, pumps, radiators, thermostats and water pipes and other components. The heat generated by the engine circulates to the radiator through the water pipe, and the heat is released to the surrounding air through the closely arranged heat sink pipes in the radiator.Two. The exhaust system is mainly responsible for excluding the exhaust gas generated by the engine and taking away the heat in it. Therefore, the exhaust system also plays a role in engine heat management. Usually, the exhaust system includes exhaust pipe, middle silencer, tail silencer and exhaust pipe and other parts. The exhaust pipe often generates a high temperature when the engine is running, and the middle silencer and tail silencer play a role in regulating the sound and preventing the exhaust gas backflow in the whole exhaust system. 3. Engine oil engine oil not only plays a lubricating role, but also has a cooling effect. When the engine oil temperature is too high, the excess heat can be dissipated through the cooler. Therefore, in the process of engine operation, keeping the engine oil within the appropriate temperature range is another important means of engine thermal management. III. Engine heatOptimization and innovation of management With the continuous progress of science and technology, engine thermal management technology is also constantly developing and innovating. From the perspective of application and research, the main direction of engine thermal management technology optimization is to improve engine heat recovery efficiency, adopt new materials, integrate technology and intelligent technology. 1. Improve the heat recovery rate of the engine. When we use the engine, we will waste a lot of heat energy, which will significantly reduce the heat utilization rate. Therefore, improving the heat recovery rate of the engine is a feasible means. The adoption of technologies such as exhaust gas heat utilization, vaporizer preheating and waste heat power generation can greatly improve the thermal energy utilization rate of the engine and reduce the impact of wasting heat energy. Two. The traditional metal materials using new materials have some defects, such as heavy weight, high cost, thermal convection performance, etc., which are difficult to meet the needs of high power, high efficiency and high reliability of the engine.The use of some new materials, such as carbon fiber composites, high-permeability silicon impurity amorphous alloy materials, etc., can achieve the effects of high strength, high rigidity and high thermal conductivity. 3. Integrated technology uses integrated technology to realize the integration of engine cooling, combustion, transmission system and other parts, and further improve the thermal management effect of the engine under the premise of ensuring that the engine performance remains unchanged. Four. Intelligent technology adopts intelligent technology to monitor and control the engine and vehicle in real time through sensors, controllers and other equipment to ensure that the engine operates in a safe, efficient and economical state. In summary, engine thermal management technology plays a very important role in the use and maintenance of vehicles. Effective engine thermal management measures can greatly extend the service life of the engine, and also improve the performance and economic benefits of the vehicle.In the development and evolution of engine thermal management technology, continuous innovation and optimization is an inevitable trend. We believe that with the exploration and joint efforts of professionals from all walks of life and the field of science and technology, the engine heat management technology will be more mature and advanced, making more outstanding contributions to the scientific and technological development of vehicles and the green environmental protection of society.
