摘要
结合汽油中胶质的构成与性质,分析了实际胶质、溶剂洗胶质、未洗胶质标准试验方法测定过程、数据差异的原因,阐述了汽油标准中胶质引用标准变更的原因,研究了添加剂间及与汽油溶剂洗胶质间的相互作用。指出汽油添加剂的无序使用是导致汽油未洗胶质超标、发动机非正常工作的主要原因。合理、有效使用极性小、非烃元素含量低的添加剂,降低胶质尤其是未洗胶质含量是保障发动机有效运行的基础。
Based on the composition and properties of gasoline gum,the standard determination method for measuring existent gum,solvent washed gum and unwashed gum were systematically analyzed to find the reasons for the different analysis results of gum content.The changes of quoted standard for gasoline gum test method and the interactions between additives and solvent washed gum were introduced.It is found that the abuse of gasoline additives is the primary reason that causes the superstandard of unwashed gum and abnormal work of engine.The rational and efficient use of additives with lower polarity,less non-hydrocarbon element and lower unwashed gum is the foundation of effective running of engine.
