Dynamic customs duty calculation

High compression ratio engine (high-performance compression engine) With the continuous progress of science and Dynamic customs duty calculationtechnology, the automobile industry is also constantly developing.Nowadays, cars have become an indispensable means of transportation in people's daily life. In the development of automobiles, engines have always been one of the key parts of automobiles. The High Compression Ratio Engine is a major breakthrough in automobile engine technology. What is a high compression ratio engine? High compression ratio engine refers to the design of high compression ratio, so that the pressure and temperature of the engine in the combustion gas increase accordingly, so as to improve the thermal efficiency and mechanical efficiency of the engine. Generally speaking, the compression ratio of high compression ratio engines exceeds 10:1, which greatly improves the output power and fuel consumption efficiency of the engine. How does the high-compression ratio engine give full play to its advantages? The high compression ratio engine mainly has the following advantages: 1. Improve fuel consumption efficiency. The higher the compression ratio of the engine, the higher the heat utilization rate of the fuel.Once the fuel is ignited, the heat generated by combustion can be used more effectively, thus improving fuel consumption efficiency. Two. Significantly improve the power output. Because the high-compression engine can produce higher pressure and temperature in the combustion chamber, the high-compression engine has a higher maximum power output and torque output. Compared with the low-compression engine, the acceleration ability will be superior. 3. Reduce pollution emissions. When the high compression ratio engine burns gas, the temperature is relatively high, and the combustion efficiency is relatively high, which can make it easy for exhaust treatment equipment to meet certain emission standards. Compared with low compression than engines, high compression is cleaner than engine emissions and reduces environmental pollution. Disadvantages of high compression ratio engine High compression ratio engine also has some disadvantages: 1. The maintenance cost is high becauseThe design of the high-compression engine is relatively complex and requires higher material and process standards, so its maintenance cost is also relatively high. Two. High requirements for fuel. Because high compression requires higher pressure and temperature than the engine, the quality requirements for fuel are relatively high, and it is necessary to choose high-standard gasoline or diesel to ensure the normal operation of the engine. 3. The engine is noisy. Because high compression is higher than the working pressure of the engine, the noise generated during operation is relatively large. Application of high compression ratio engines High compression ratio engines are currently widely used in some high-performance cars, such as cars and sports cars of Audi, BMW, Porsche and other brands. In addition, some racing cars and sports cars often use high compression ratio engines. In addition, high-compression ratio engines are also used in some hybrid and all-electric vehicles to improve their fuel efficiency and power output.In a word, the emergence of high compression ratio engines has greatly promoted the development of automobile engine technology. Its birth has not only changed the automobile industry, but also put forward higher requirements for environmental protection and energy utilization. With the development of science and technology in the future, there is still a lot of room for development of high-compression engines. It is believed that it will be more widely used and play a more important role in the future.
