摘要
汽油的特性参数对汽油机的燃烧和排放具有重要影响。通过对市售汽油特性参数间关系的统计分析,得到了汽油密度同汽油的平均氢碳原子数之比和汽油空气混合气的理论空燃比之间的线性关系式。这些统计关系式可用于由测量的汽油密度值推测汽油平均氢碳原子数之比和汽油空气混合气的理论空燃比等,还可用于改善汽油机热计算精度和汽油机空燃比的测量、控制精度。
The parameters of property of gasoline have a great effect on the combustiom and emissions of gasoline engines. The statistical analysis of relationship between parameters of property of gasoline sold on market was carried out. The linear equations between the density and hydrogen carbon ratio H/C, and the stoichiometric air-fuel ratio for gasoline sold on market were obtained. These equations can calculate hydrogen carbon ratio H/C, stoichiometric air-fuel ratio and so on by measuring density of gasoline. These equations can also improve the precision of thermal analysis, measurement and control of air-fuel ratio of gasoline engines.
