HS code mapping to non-tariff measures

Engine turbine: the key part to improve the power of the car. As we all know,HS code mapping to non-tariff measures the improvement of car power can be attributed to two aspects: fuel supply and exhaust emissions.The engine turbine uses exhaust to drive a turbine impeller, thus improving the output power and torque of the engine. So, what exactly is the engine turbine and how does it work? I. The principle of engine turbine. Engine turbine is a device that uses the exhaust gas discharged by the engine to drive the power machine. Generally speaking, it is a small fan driven by exhaust energy to send compressed air to the engine to achieve the purpose of increasing power output. There is a certain amount of energy in the process of engine exhaust, and the engine turbine collects these energies and converts them into power to provide driving force to the car. Engine turbine components include intake duct, turbine, intercooler, shell and exhaust duct. When the car's engine is running, the exhaust will pass through a series of small blades of the turbine, causing the turbine to start rotating. FollowThe part of the engine that enters after the turbine and compressed air is connected by a shaft, so when the turbine rotates, the air will also be compressed. This process is called "turbocharger", which is what we often call "turbocharger". II. Types of engine turbines on the market, turbocharging devices are subdivided into two types: single turbine and twin turbine. At present, twin-turbo is mainly used in high-end luxury cars and sports cars with a more atmospheric appearance, while single-turbo is widely used in Volkswagen models. In addition, the rear turbine is also a turbocharging method. Compared with the front turbine, it is susceptible to pipeline blockage and overheating during the exhaust process, and produces less oil smoke. III. Advantages and disadvantages of engine turbines The advantages of engine turbines are mainly reflected in: 1. Increase the power output.Turbocharging can make full use of the energy in the exhaust, so that the power output of the engine is greatly improved, the acceleration performance is also improved, and the car feels more powerful. Two. Improve fuel consumption efficiency. Although turbocharging requires part of the energy to drive the turbine, under the same output power, compared with the naturally aspirated engine, turbocharging can reduce fuel consumption under the premise of the desired effect. 3. Improve maintenance efficiency. The compact exhaust system makes the engine easier to maintain. Of course, turbocharging also has shortcomings: 1. The price is high. Because the turbocharging device requires a complete set of supercharging system, it is more expensive than naturally aspirated. Two. It is more prone to malfunctions. Turbocharging requires a lot of maintenance, and failures are more likely to occur. IV. Conclusion Engine turbine is an important means to improve automobile power and reduce fuel consumption.Due to the impact of energy consumption and failure, the application of turbocharging also needs to be more cautious and moderate. Therefore, when buying a car, it is necessary to weigh performance, fuel consumption and economy in order to choose the most suitable car to get a good driving experience.
