研制了一种光纤燃烧传感系统，它能够测量发动机燃烧火焰发射光谱强度随时间的变化曲线。试验中测量了ＣＨ（４３１ｎｍ）、Ｃ２（５１６ｎｍ）及Ｈ２Ｏ＊（５８８ｎｍ）三种特征谱线在不同工况下的光强变化曲线。试验结果表明，光强变化曲线能够反映燃烧过程进行的好坏及燃烧的时间特性，可以用来进行燃烧诊断和分析。所研制的光纤燃烧传感器可作为现代发动机管理系统的反馈控制传感器 A fiber optic combustion sensing system was developed, which can measure the curve of emission intensity of the combustion flame of engine over time. The experiment measured the light intensity curves of CH (431nm), C2 (516nm) and H2O * (588nm) under different conditions. The test results show that the light intensity curve can reflect the quality of the combustion process and the combustion time characteristics, which can be used to diagnose and analyze the combustion. The developed optical fiber combustion sensor can be used as the feedback control sensor of the modern engine management system
