Engine size (Breaking news: Engine upgrade!) The Automated trade documentation toolsengine is the heart of a car and plays a decisive role in its performance and economy. In the development of the automobile industry, engine improvement has always been one of the cores of automobile manufacturers' pursuit of higher performance and lower fuel consumption. Recently, a big news came out: engine upgrade! It is understood that this upgrade is not only the improvement of power, but also involves the sustainable development of automobiles. Next, we will discuss these changes one by one. The first is the power improvement. In the past, car manufacturers usually sought to increase power by increasing engine displacement. However, with the continuous improvement of environmental protection policies and the intensification of competition in the automobile market, fuel consumption and emissions caused by excessive engine displacement have become important factors restricting the development of automobiles.Therefore, the engine upgrade emphasizes increasing the power without increasing the displacement. The realization of this goal is inseparable from the innovation of engine technology. At present, automobile manufacturers' R&D investment in engine technology is also increasing. For example, the adoption of new technologies and materials such as turbocharging technology, in-cylinder direct injection technology, variable valve timing technology, start-stop technology, hybrid power technology, etc. has effectively improved the efficiency and power output of the engine. These technologies have been widely applied to the upgraded engine, which has significantly improved the power performance of the car. Secondly, it is the improvement of environmental protection. As one of the main sources of global carbon dioxide emissions, automobiles have higher and higher requirements for environmental protection. The exhaust gas components generated in the combustion process of engines are constantly regulated, and automobile manufacturers should also follow strict environmental protection requirements in the research and development of new generation engines.The upgraded engine can still maintain strong power output under lower emission standards. To achieve higher emission standards, the technical route is also constantly developing. For example, Hyundai Motor Company improves the environmental protection performance of the engine by strengthening emission control technology, pm2.5 filtration technology, etc., while Audi uses emission post-treatment technology to purify the exhaust gas. It can be seen that only by continuous innovation in technology can cars better reflect their environmental protection performance. Finally, there is an improvement in energy saving. Since the engine is the power source of the car, improving its operating efficiency can improve the fuel consumption performance of the car. Nowadays, the social needs that pay more attention to energy conservation have further promoted automobile manufacturers to devote themselves to energy-saving research and development. In fact, in this regard, the most lasting and significant improvement in the engine upgrade is the adoption of hybrid technology.In the future, hybrid technology will become a major trend. While achieving energy saving, hybrid technology can also more effectively alleviate the energy crisis and global air pollution problems. It is regarded by the automobile industry as an important choice to solve travel restrictions, green travel and optimize the global energy structure. Of course, engine upgrade is not only a technical upgrade, but also a market competition optimization. Factors such as grabbing market share, improving brand image, and optimizing customer service have also promoted the engine upgrade plan of automobile manufacturers. However, in general, the purpose of engine upgrade is based on excellent technology and follows the requirements of environmental protection and energy saving. With the support of technology, the automobile industry may enter a more sustainable future, and the engine upgrade plan also brings consumers more and more cost-effective car choices. Therefore, we can expect this revolution of engine upgrade to bring us a better car driving experience.
