配气机构优化技术的发展现状和趋势

Current Status and Developing Trend of the Optimization Technology for Valve-train

配气机构是发动机的重要组成部分,其性能的优劣决定着发动机性能。文中从发动机目前使用的配气机构技术、配气机构优化参数以及配气机构优化方式等几个方面介绍了国内外配气机构发展现状和发展趋势。配气机构将会朝着气门升程、配气相位及进气管都可变的全可变技术和无凸轮轴可变技术方向发展。

Valve train is an important component in an engine, and the performance of the valve train determines the performance of an engine. This paper discusses the current status and future developing trend of the technologies, optimization parameters and optimization way for valve train in an engine at home and abroad. In conclusion, the valve train will develop toward a full variable technology for vale-lift, valve timing, intake-pipe, or variable technology for no camshaft.
