HS code intelligence in freight auditing

China's engines (new progress of China's independent research and HS code intelligence in freight auditingdevelopment of engines) In recent years, China's independently developed engines have gradually emerged in the international market and received more and more attention and favor.In automobiles, aviation, ships and other fields, China's engines are gradually replacing imported products and becoming an important force in the industry. Next, let's take a look at the new progress of Chinese engines in technology, market and personalized applications. Technical aspects: Break through key technical problems and realize a number of independent innovations. All along, China's engine technology has been constrained, and imported products have occupied a dominant position in the market. However, in recent years, Chinese engine manufacturers have continuously made breakthroughs in conquering key technologies and achieved a number of independent innovations. For example, in the field of passenger car engines, domestic automobile enterprises have taken the lead in developing low-emission, high-power and high-efficiency engines, which provides a solid technical guarantee for the sustainable development of the automobile industry; in the field of diesel engines, domestic manufacturers have successfully broken through the core technology and developed a new generation of diesel engines that meet European standards.In addition, China has also made major breakthroughs in the field of aircraft engines. In 2018, China's first independently developed ARJ21 aircraft was officially put into operation, marking China's fifth country to independently produce large jet airliners after the United States, Europe, Russia and Canada. In the future, China is planning to develop a more advanced C919 aircraft. The engine of the aircraft will also adopt a high-efficiency and low-noise turbofan engine independently developed by China, which will inject more impetus into the development of China's aviation industry. Market: Gradually replace imported products and improve the localization rate. With the continuous improvement of China's independently developed engine technology, they have also gradually replaced imported products and become an important force in the market. At present, in the domestic car market, independent brand engines occupy more than 70% of the market share.In the field of ships, Chinese engine enterprises have also gradually gone abroad, participated in international competition, and become important suppliers in the international market. In addition, in the field of military industry, China's engines have gradually replaced imported products, improving the localization rate and ensuring national defense and security. Personalized application: Helping the development of manufacturing and new energy vehicles. In addition to traditional fields, Chinese engines are also helping the development of manufacturing and new energy vehicles. In the manufacturing field, engines have become the core components of various engineering machinery, agricultural machinery, roadside construction equipment, etc., and play a key role. In the field of new energy vehicles, China's independently developed power batteries, electric drive systems and motor control technologies have reached the international leading level, which is the promotion of new energy vehicles. Widespreadization provides strong support. In a word, China'sEngines have made great progress in technology, market and personalized applications, and have become an important force in various fields. In the future, with the continuous improvement of independent innovation ability, China's engines will definitely play a more important role in the international market.
