从我国车用汽油质量标准发展历程出发,对其重要技术指标的演变进行探讨。指出今后车用汽油将向着降低硫、烯烃、芳烃、苯含量,提高辛烷值,减少金属添加量,缩短蒸汽压、馏程范围,控制密度等清洁化的方向趋严发展。
從我國車用汽油質量標準髮展歷程齣髮,對其重要技術指標的縯變進行探討。指齣今後車用汽油將嚮著降低硫、烯烴、芳烴、苯含量,提高辛烷值,減少金屬添加量,縮短蒸汽壓、餾程範圍,控製密度等清潔化的方嚮趨嚴髮展。

Based on the development course of gasoline quality standards for motor vehicles in China, the evolution of the important motor gasoline technical indexes was discussed. It was pointed out that the development of motor gasoline in future will tend to reduce the contents of sulfur, olefins, aromatics and benzene, improve octane value, decrease the amount of metal added, narrow the range of vapor pressure and distillation and control the density, which will make the motor gasoline cleaner.
