| 摘 要： | 二冲程汽油机排气污染严重，尤其是燃烧混合油，浓混合气时有害物排放量时。着火时刻火焰光谱分析表明，ＣＨ（４３１．５ｎｍ）及Ｃ２（５１６．５ｎｍ）自由基光强峰值比较强，尤其是ＣＮ（３８７ｎｍ）自由基光强峰值比较突出。根据Ｆｅｎｉｍｏｒｅ机理可以解释排气中ＮＯｘ的生成机理。这一点也为日本Ｎａｇａｓｅ的试验所验证。

| Abstract: | In a two-stroke gasoline engine, exhaust gas pollution is especially severe when it burns rich mixture of blended fuel. The results of spectra analysis of ignition combustion flame show that the peak luminous intensities of three characteristic spectra CH(431.5nm), C2(516.5nm) and CN(387nm) are strong, of which the peak luminous intensity of CN(387nm) is the most outstanding. The mechanism of NO(x) formation in exhaust gas can be illustrated by Fenimore theorem. The mechanism was also verified by experiments conducted by Japanese researcher K. Nagase. |
