HS code verification for exporters

Engine emission standards: the new car introduces the "national six b" electronic control system,HS code verification for exporters the fuel oxidation catalyst reduces pollution With the continuous development of the automobile industry, the car With the increase in the number of vehicles, car exhaust emissions are also becoming more and more a topic of concern. As one of the main sources of pollution, automobile exhaust emissions have a significant impact on the environment and human health. In order to reduce the pollution of automobile exhaust, China has implemented multiple engine emission standards. Recently, our countryThe national 6b standard has been officially implemented, and new technologies such as electronic control systems and fuel oxidation catalysts have been introduced to better reduce automobile exhaust pollution. The national six b standard refers to the latest version of China's sixth phase emission standard. Compared with the previous version, the National 6b standard is stricter in pollutant emission restrictions and covers a wider range of models. The standard has strict emission restrictions on a variety of pollutants such as nitrogen oxides, hydrocarbons and particulate matter. From 2023, all newly listed gasoline vehicles must meet this standard. In order to meet the national 6b standard, automobile manufacturers need to introduce new technologies and equipment. The most important of them are the electronic control system and the fuel oxidation catalyst. These two technologies can greatly reduce the pollution of automobile exhaust, and also significantly improve the fuel economy, stability and reliability of automobiles.Electronic control system is one of the indispensable core technologies in modern automobiles. It monitors and controls the operating status of the engine in real time through computers, sensors and other equipment to ensure that the engine can work in the best state. In terms of emission control, the electronic control system can accurately control the fuel injection, air intake and other parameters of the engine, so as to make the combustion of the engine more adequate, thus reducing exhaust emissions. Fuel oxidation catalyst is a device that reduces automobile exhaust pollution through chemical reactions. It reduces the emission of harmful substances in the exhaust gas by introducing the exhaust gas containing harmful substances into the catalyst, and converting some of the substances into harmless gases through the action of the catalyst. This device can be widely used in automobiles and other machinery and equipment, with the advantages of low cost, good effect, simple maintenance and so on.The introduction of new technologies such as electronic control systems and fuel oxidation catalysts can not only reduce automobile exhaust emissions, but also improve the fuel economy and stability of automobiles. Fuel oxidation catalyst can reduce the fuel consumption of automobiles and improve the efficiency of fuel utilization. The electronic control system can control the working state of the engine so that it is always in the best working state, thus improving the performance and reliability of the car. In short, as a major source of pollution, automobile exhaust pollution is a threat to the environment and human health that cannot be ignored. The introduction of the National 6b standard and the introduction of new technologies can better protect the environment and human health, and also promote the development and upgrading of the automobile industry. We should welcome and support the wide application of these new technologies, actively advocate the concept of energy conservation and emission reduction and green travel, and work together to build a green and low-carbon social environment.
