摘　　要：以某汽油机可变气门驱动系统(VVA)为研究对象,利用AMESim软件建立仿真模型,研究VVA系统的液力特性,并在此基础上研究液压油温度和泄漏对VVA系统性能的影响。分析结果表明:通过控制电磁阀的开关时刻,可以实现气门升程和相位连续可变;气门关闭速度随温度降低而减小;液力系统泄漏量增加,会造成气门升程降低。1-D simulation model of gasoline engine VVA system was established with AMESim. Hydraulic properties of VVA system were analyzed,therefore effects of oil temperature and system leakage on VVA performance were studied base on system analysis. The result showed that variation of valve lift and timing could be achieved by controlling solenoid valve. Valve closing velocity will be shortened with oil temperature decrease,and system leakage will cause the maximum valve lift decrease.
