2.0 engine (updated engine: 2.0 power upgrade scheme) In the automobile market,UEFA Champions League live streaming free the engine is regarded as the "heart" of the car.Now, with the innovation of science and technology, the 2.0 engine has appeared. The 2.0 engine has the characteristics of more powerful data, smaller and smaller noise, better and better environmental protection performance, and greatly improved power performance. This article will introduce the 2.0 engine in detail from the following aspects. 1. The power performance improvement 2.0 engine adopts turbocharging, which can effectively improve the power performance of the engine. Compared with traditional engines, the 2.0 engine can improve the power, performance and fuel economy of the engine by increasing the exhaust and intake flow ratio, increasing the intake pressure and reducing the exhaust temperature. As we all know, the greater the power of the car, the higher the fuel consumption of the engine. Therefore, the 2.0 engine also adopts in-cylinder direct injection technology, improvement of cylinder head and piston materials, reasonable exhaust system design, etc.The combination of these technologies can achieve stronger engine output and ensure the balance between fuel economy and power performance. Two. Noise reduction Noise has always been a pain point in the automobile industry. However, the current 2.0 engine noise is lower than that of the previous car engine. This is because the 2.0 engine adopts a variety of technical measures to reduce noise generation. The first is the application of acoustic technology, which controls the thermal sound, mechanical sound to the source of noise of the engine, so that the noise of the engine is maximized. Secondly, the improvement of engine parts and materials, especially the use of ceramic products for high-temperature parts, can effectively reduce the generation of noise. In addition, the supercharging technology of pumping can reduce the air noise of the engine, and through the perfect exhaust system design, the noise of the engine has also been greatly reduced.3. The improvement of environmental protection performance 2.0 engine has also made a lot of efforts to improve environmental protection performance. The most obvious of them is the reduction of exhaust emissions. This is achieved by installing nitrogen oxide concentration sensors, particle number sensors and other instruments in the engine channel, and with the cooperation of the measurement and control system, accurate injection of fuel and gasoline and double-bridge steam mixing technology are carried out. In addition, there is also exhaust gas recovery technology, which can recycle the thermal energy and qualitative energy of the exhaust gas, thus greatly reducing exhaust emissions. In summary, the new technology adopted by the 2.0 engine has become the most popular engine in the modern automobile market with its excellent power performance, low noise and good environmental protection performance. In the future, with the progress of more science and technology and innovation, the 2.0 engine will have more improvements and upgrades, so that we can look forward to better performance.
