柴油机进气门晚关系统关键参数对进气性能的影响研究OA北大核心CSCDCSTPCD
Effects of Key Parameters of Diesel Late Intake Valve System on Intake Performance
针对DK4A柴油机电液进气门晚关机构，建立了柴油机的数值模型，分析最大升程限位下进气迟闭角对柴油机进气质量流量的影响，研究了附加升程限位与进气迟闭角对进气状态参数的影响。研究表明，最大附加升程限位对进气质量流量影响很小，相同进气迟闭角度下的进气流量变化率均小于3％，且随着进气迟闭角度的增大，进气流量减小；进气迟闭角增大有利于增长滞燃期，降低压缩终了的压力和温度，而最大附加升程限位对压缩终了温度和压力影响很小，在相同进气迟闭角下的温度和压力的变化率均小于5％。
A numerical model of DK4A diesel engine was established on the basis of its electric hy-draulic mechanism .The effects of intake valve closing angle on the intake flow rate of the diesel engine were analyzed under a certain maximum lift limit .The effects of the additional lift limit and intake valve closing angle on the intake state parameter were studied .Results indicate that the maximum ad-ditional lift limit has a little effects on the intake flow rate …查看全部>>
