摘　　要：全可变气门机构能实现发动机配气定时和气门升程的连续可变,是可变气门技术的发展趋势。本文主要分析了全可变气门技术的优越性,论述了当前应用全可变气门技术的典型机构,最后介绍了一种新型全可变液压气门机构。通过实验证明这种液压气门机构可通过改变泄油初始相位角实现进气门最大升程和进气迟闭角的连续可变。Fully variable valve train may realize continuously variable valve timing and valve lift,and so it represents development trend of variable valve technology.The paper analyzes the superiority of fully variable valve technology and introduces some typical mechanisms of fully variable valve technology.A new kind of mechanical hydraulic fully variable valve train is discussed.Test results show that the hydraulic valve actuation system can realize continuously variable valve lift and the early intake valve closing by changing the time of oil pressure release.
