为了研究离子电流信号在HCCI燃烧负荷拓展控制中的应用,研制了一套用于SI/HCCI双燃烧模式下离子电流检测装置,检测出两种模式下的离子电流信号,取得了满意的效果。研究表明离子电流信号能够良好地指示实际燃烧过程,如燃烧定时、非正常燃烧等,可为HCCI燃烧控制提供非常重要的信息。
To study ion current in load expanding control of HCCI, we developed an ion current detection device and detected the ion current signal in SI/HCCI dual-mode combustion with satisfactory results. The study shows that ion current signal can be an excellent indicator of the actual combustion process, such as combustion time, non-normal combustion state, which can provide crucial piece of information for HCCI combustion control.
