摘　　要：基于汽油质量标准中关于燃料燃烧清洁性、氧化安定性等项目的更新、变化,结合油品加工生产、调合工艺,将汽油化学组成的结构和性质与油品燃烧清洁性、氧化安定性相关联。指出汽油含有的不饱和烃及非烃是影响其燃烧清洁性、氧化安定性的关键因素;以烯烃为主的不安定组分发生自由基链氧化反应是汽油安定性变差的根本。严格控制汽油不饱和烃及非烃含量是提升油品燃烧清洁性、氧化安定性、保障发动机有效运行的基础。Based on the update and change of fuel combustion cleanliness and oxidation stability in gasoline quality standards,combined with gasoline processing production and blending process,the structure and properties of gasoline chemical composition are related to oil combustion cleanliness and oxidation stability.It is pointed out that the unsaturated hydrocarbons and non-hydrocarbons contained in gasoline are the key factors affecting the combustion cleanliness and oxidation stability.The radical chain oxidation reaction of the unstable components mainly composed of olefins is the basis for the deterioration of gasoline stability.Strict control of gasoline unsaturated hydrocarbons and non-hydrocarbon content is the basis for improving the cleanliness of oil combustion,oxidation stability,and ensuring efficient operation of the engine.
