| 摘 要： | 在1台装备了自主开发的电控液压驱动可变气门机构的进气道喷射单缸试验发动机上,成功地实现了汽油机SI燃烧和可控自燃(CAI)燃烧。研究结果表明,采用自主研制的电液无凸轮轴气门机构能够实现可变气门定时及可变气门开启持续期;该机构在SI模式下能满足发动机的动力性要求且燃油经济性和CO,HC排放有所改善;通过排气门早关、进气门晚开策略,在转速为1 000 r/min、过量空气系数为1的工况下,进气门开启506~511°CA,排气门关闭242~278°CA气门正时范围内实现了CAI燃烧,CAI燃烧获得的最大平均有效压力可达0.395 MPa。

| Abstract: | The controlled auto ignition(CAI) combustion and spark ignition(SI) combustion were realized in a PFI gasoline engine equipped with self-developed electro-hydraulic valve train.The results show that the variable valve timing and duration can be realized with the electro-hydraulic valve train.Moreover,the mechanism can meet the engine power performance and improve the fuel economy,CO and HC emission under the mode of SI.With LIVO and EEVC strategies,the CAI combustion is realized in the timing ranges of IVO ... |
