摘要
利用高时间光谱分辨率探测系统，研究了汽油机在着火早期燃烧生成物ＣＨ，Ｃ２，ＯＨ，ＣＨ２Ｏ，Ｏ２等的光谱；根据这些着火期生成物的光谱响应研究了人花塞点火放电过程的产生、变化和早期火焰的发展情况，并对点火燃烧期内有害排放物的生成量进行了分析。
y using a detecting system with a high spectral time-resolution , the spectra of the com-bustion products including those of CH,C2, OH, CH2O and O2 in the early stage of ignitionin a gasoline engine are studied.The beginning and evolution of the ignition process as wellas the progress of the early flame can be shown clearly by the spectral response,With thespectrum method , one can obtain more accurate information about the ignition delay, the rel-ative amounts of some intermediate products during ignition , the properties of the steadycombustion and flame diffusion, the starting and combustion rate in the early stage and theformation of poisonous exhaust gases during the ignition in the gasoline engine.
