可变技术在经济型轿车发动机中的应用及前景

Application and Prospect of Engine Variable Technology for Economy Car

发动机的整体性能直接决定汽车的动力性、经济性和排放特性。因此,采用何种技术路线来提高发动机的整体性能以应对能源与环境问题对汽车节能减排的挑战成了汽车制造业的重中之重。文章通过对当今市场上被广泛应用的几种可变技术进行详细介绍,显示了可变技术在汽车发动机研发中的应用前景,为找到一种有效提高汽车节能减排能力的途径提供了理论帮助。

The overall performance of the engine directly determines the car＇s dynamics, economy and emissions characteristics. Therefore, how to improve the overall performance of the engine in response to the energy crisis and bad environment for automotive energy conservation challenge became the top priority of the automobile manufacturing industry. Some detailed descriptions of several variable technologies which are widely used on the market today are included in this paper. It indicated that the variable technology will be widely used in the development of cars in the future. In the paper, the author will try to find a way to improve the energy conservation and emission reduction in cars.
