摘要
介绍了国内外可变气门技术的发展状况。并根据气门控制参数的变化情况,对可变气门技术进行了详细的分类。结合目前典型的可变气门机构,对实现可变气门技术的途径进行了系统的阐述与评价。通过实例介绍了可变气门技术改善发动机性能及在实现汽油机均质充量压缩着火(H CCI)方面的应用。通过分析指出,叶片式可变凸轮轴相位机构是目前可行性较强的技术途径。
Development of variable valve technology in the world is introduced.According to variation of valve control parameters,variable valve technology is classified in detail.Combined with today＇s typical variable valve mechanism,approaches to realize the variable valve technology are systematically stated and evaluated.With an example, application of the variable valve technology to improve engine performance and the homogeneous charging compression ignition are introduced.h is pointed out through analysis that the blade type variable camshaft phase mechanism is a more feasible technology approach at present.
