| 摘 要： | 应用火花塞光纤传感测量系统对BJ492Q汽油机爆燃燃烧进行测量和研究,分析了爆燃燃烧时火焰光辐射的变化情况。正常燃烧时,CH（431．5nm),C2(516.5nm),H2O(588nm)自由基的光强曲线出现双峰值,着火延迟期内自由基光辐射。爆燃较强工况时,只出现一个峰值,主要是碳粒子热辐射,峰值处出现剧烈波动,相位提前,无自由基的光辐射。试验表明,火花塞光纤传感器完全可用于爆燃测量。

| Abstract: | Researches on knock combustion in BJ492Q using spark plug optica l sensors are presented in this paper.The effects of knock intensity on light em ission are studied.In normal condition at theoretical A／F ratio,double peaks a ppear on luminous curves of CH(431.5 nm),C2(516.5 nm),and H2O（588 nm ） radicals,with one of the peaks appearing in the delay combustion process.But under high knock intensity condition,only one peak appears due to the thermal ra diation of carbon particle.High frequent fluctuations appear near the peak,with phase advanced and light emission of radicals disappearing.The use of the spark plug sensor is proved to be feasible in knock combustion detection. |
