The blue flame reaction is a real issue for the ignition of hydrocarbon fuel/air mixtures in internal combustion engines. Once a blue flame has appeared, the onset of hot flame is inevitable, except for very special cases. Blue flame generates carbon monoxide briskly, and is the final induction stage of oxidation up to the carbon dioxide ; the hot flame ignition. Compression ignition of n-butane/air mixtures was examined using a rapid compression machine. History of chemical species during induction period was obtained. Carbon monoxide concentration is always higher than of the carbon dioxide during the whole induction period and its maximum is caused at the very late stage of blue-flame or the very early stage of hot-flame onset. At the time just before the final hot-flame ignition the carbon-monoxide concentration comes up to around 7000 ppm, whether the mixture is lean or stoichiometric. Lower carbon-monoxide concentration is observed in the case no hot-flame is established. Carbon-monoxide concentration attained during the blue-flame period would be an indication or a criterion for the transfer to the final hot-flame ignition.

蓝焰反应是内燃机中烃类燃料/空气混合物点火的一个现实问题。一旦出现蓝色火焰，除了非常特殊的情况外，热火焰的出现是不可避免的。蓝色火焰迅速生成一氧化碳，是氧化至二氧化碳的最后诱导阶段；热火焰点火。采用快速压缩机对正丁烷/空气混合物的压缩点火进行了研究。获得了诱导期化学物质的历史。在整个诱导期内，一氧化碳浓度始终高于二氧化碳浓度，其最大值出现在蓝焰极晚期或热焰发作极早期。在最后的热火焰点燃之前，无论混合物是稀薄的还是化学计量的，一氧化碳浓度都达到了7000 ppm左右。在没有建立热火焰的情况下，观察到较低的一氧化碳浓度。在蓝焰期间达到的一氧化碳浓度将是过渡到最后的热焰点火的指示或标准。
