摘要
为D20发动机进气连续可变凸轮轴相位器(CVCP)系统设计和搭建了相位器动态响应特性测试平台,并建立了基于AMESim的可变气门正时系统仿真模型;通过仿真与测试,对CVCP动态响应特性的影响因素进行了深入的研究,得出了机油温度与压力和发动机转速等发动机运行参数以及机油控制阀流量特性与相位器结构尺寸等VVT系统结构参数对相位器响应特性的影响规律,为提高CVCP系统响应速度提供了方向。
A test rig for phaser dynamic response characteristics is designed and constructed for the continuously variable cam phaser （CVCP） of D20 engine induction system, and an AMESim-based simulation model for variable valve timing （VVT） system is built. An in-depth investigation into the influencing factors of CVCP dynamic response characteristics is conducted by both simulation and test, to reveal the rule of the effects of engine operation parameters （ oil temperature and pressure and engine speed） and the structural parameters of VVT system （ the flow rate characteristics of oil control valve and the structural dimensions of phaser） on phaser response characteristics, offering a direction for increasing the response speed of CVCP system.
