Customs duty prediction models

The Customs duty prediction modelsbest engine of domestic cars (top engine inventory of domestic cars) In the rapid development of China's automobile market, the popularity of domestic cars is also gradually increasing, and the technology and quality of domestic cars are also getting better and better, especially Innovation and progress in engine technology have increased consumers' confidence and choice when choosing domestic cars.So, which engines in domestic cars are our top engines? Let's take a look together. I. Geely TGDI engine Geely TGDI engine can be regarded as one of the earliest engines in China to enter turbocharging technology. It adopts Turbocharged gasoline direct injection technology and has high efficiency. , power, energy saving and other multiple advantages. Its maximum power can reach 150kW, the peak torque can reach 265N.m, and its power performance is excellent. Geely TGDI engine has outstanding performance in terms of fuel efficiency, emissions and other aspects, and has been adopted by many Geely models, becoming one of the driving forces of Geely brand reputation. II. Chang'an BlueCore Engine Chang'an Automobile BThe lueCore series engine can be said to be the only one in China to win the Jiangsu Technology Innovation Award, adopting a number of independent patented technologies. The engine is positioned as a high-performance and high-efficiency engine, with a peak power of up to 173kW. Compared with traditional engines, the fuel efficiency is improved by more than 20%, and the emissions also follow international standards and meet the highest emission standards of WVTA. It is a model of domestic engine research and development that meets European emission standards. III. SAIC 1.5TGDI engine SAIC's 1.5TGDI engine adopts lightweight materials, ductile iron cylinder blocks, and high reliability. Its exhaust volume is relatively common in domestic cars, but it adopts twin-turbocharging technology, which can easily obtain a maximum torque of 290N.m without reducing fuel consumption, which improves performance by more than 30% compared with traditional engines.In terms of fuel economy, the SAIC 1.5TGDI engine performs well, with a fuel consumption of only 5.6L per 100 kilometers, which is a high-performance and efficient domestic engine. IV. Beijing Hyundai Smart Stream G1.6T engine The biggest feature of Beijing Hyundai Smart Stream G1.6T engine is the adoption of LNT technology, that is, low-temperature nitrogen oxide catalytic conversion technology, which reaches the national six b in the emission standard. At the same time, it can also achieve low fuel consumption. Although the maximum power of the engine is not outstanding, its maximum torque is 265N.m, which is also increased by about 30%. V. BAIC EX1.6TGDI engine BAIC EX1.6TGDI engine adopts a unique double injection direct injection technology, which can be used inHigh oil volume and multiple injections while maintaining its energy conversion efficiency can achieve higher energy utilization efficiency. It has excellent performance in terms of power output and fuel economy, and is also the best among domestic engines. In general, the above five domestic engines are innovating and making progress in different technical fields, which can be regarded as the top engines in domestic cars. Of course, with the continuous innovation of technology and the market, the engine research and development and progress of domestic cars will continue.
