摘要
随着全球对环境和能源问题的日益关注,控制和治理汽车尾气排放已成为世界各国的重要课题.车用汽油在发动机中燃烧做功的过程中,其中的不安定组分容易发生复杂的氧化聚合反应,逐步形成积炭与焦质,在发动机的进气阀、喷油嘴和燃烧室等部位形成沉积物,影响发动机的正常工作,并且使汽车排放污染物增加.汽油清净剂已经在世界范围内广泛应用,用于减少积炭的生成和积累.从积炭的危害和汽油清净剂的作用机理、国内外汽油清净剂使用现状、添加方式、标准情况和未来发展趋势等方面进行综述,提出了我国汽油清净剂的发展建议.(图6表1参考文献11)
Abstract
As global attention to environmental and energy issues has increased,the control and mitigation of automotive exhaust emissions have become an important issue for countries around the world.During the combustion process of automotive gasoline in the engine,the unstable components are prone to complex oxidative polymerization reactions,gradually forming carbon deposits and coke,which form deposits in the intake valves,fuel injectors,and combustion chambers of the engine,affecting the normal operation of the engine,and increasing vehicle emissions of pollutants.Gasoline oil purifiers have been used worldwide to reduce the generation and accumulation of carbon deposits.A comprehensive review was presented on the hazards of carbon deposits,the action mechanism of gasoline detergents,current use status,addition methods,standards,and future development trends of gasoline detergents both domestically and internationally.Furthermore,development suggestions for gasoline detergents in China was proposed.(Charts6 Table1 References11)
