WTO harmonization and HS codes

Engine structure is WTO harmonization and HS codesthe core of the car performance. With the continuous development of technology, the engine of cars is also constantly upgrading. In order to improve the performance of the car, it is an essential step to reconstruct the engine structure. I. Existing engine structural defects The structure of the gasoline engine commonly used at present has the following defects: 1. Incomplete combustion, wasting fuel consumption: The combustion method of traditional gasoline engines is to ignite after mixing gasoline with air. However, the combustion is not complete, resulting in a large amount of fuel consumption and waste, and at the same time, a large amount of toxic gases will be emitted to pollute the environment. Two. Slow acceleration response: The acceleration response of traditional engines is slow, and it takes time to increase the speed.3. Energy waste: The mechanical loss and friction of the engine produce a large amount of energy waste. The above problems affect the performance of cars and make cars lose their advantages in the competition. Therefore, rebuilding the engine structure is a necessary measure to improve the performance of the car. II. Restructuring the engine structure Reconfiguring the engine structure can be realized in the following ways: 1. Application of direct injection technology: Direct injection technology injects gasoline directly into the engine cylinder, making the combustion more adequate, thus improving the combustion efficiency. At the same time, this technology can also reduce pollution emissions. Two. Use turbocharging: Turbocharging can improve air flow and increase the fuel mixture, thus improving the acceleration ability of the car. 3. Use hybrid power system: Hybrid power system refers to a system that combines electric and fuel engines. The system can reduce combustion products and fuel consumption while meeting the power needs.Because fuel combustion only occurs when necessary, hybrid cars can be driven in zero-emission mode. Four. Adopt waste heat recovery technology: Waste heat recovery technology means to utilize the exhaust gas and waste heat emitted by the engine to further improve engine efficiency and reduce heat waste. III. Benefits of engine structure reconstruction. By restructuring the engine structure, the car can achieve the following benefits: 1. Improve fuel efficiency and performance: The application of direct injection technology can improve the fuel efficiency and performance of the engine, turbocharging can increase air flow, hybrid power systems can better balance fuel consumption and power demand, and waste heat recovery technology can reduce energy loss. Two. Reduce emissions: The optimized engine structure can reduce exhaust emissions and CO2 emissions and reduce the impact on the environment. 3. NodeSave fuel costs: By improving the fuel efficiency of the engine, the fuel cost of the car will also be reduced accordingly. In addition, hybrid cars can also be charged without using fuel, so they have the dual advantages of cost-saving and environmental protection. Four. Improve the driving experience: Improving the acceleration response and engine efficiency can provide drivers with a more comfortable driving experience. Summarizing, restructuring the engine structure is a necessary task to improve the performance of the car. By adopting direct injection technology, turbocharging, hybrid power system and waste heat recovery technology and other technical means, cars can achieve more efficient, environmentally friendly, economical and competitive performance. In the future, with the continuous advancement of technology, we can look forward to the emergence of more advanced and sustainable engine technology.
