摘要
环保法规的日益严格使得燃料清洁化的需求越来越迫切。汽油中烯烃、芳烃等组分易在发动机进气系统以及燃烧室生成沉积物,燃烧室沉积物增加会影响发动机性能,并导致尾气排放增加。在汽油中加入汽油清净剂可有效地清除喷嘴及进气阀处沉积物,减少排放,但不同的汽油及汽油清净剂对燃烧室沉积物(CCD)有不同的影响。主要综述了汽油组成以及不同组成汽油清净剂对燃烧室沉积物的影响,并提出了关于发展清洁汽油的建议。
The refining industry is facing the most serious challenge recently with the environmental protection regulation becoming strictly. Globally, there are an increasing demand for refined products and a worldwide tendency to shift to the cleaner fuels at the same time. The olefin and aromatics in gasoline are easy to form combustion chamber deposit （CCD） in the engines. Adding gasoline detergents into the gasoline can not only decrease the deposits of nozzle and intake valve, but also decrease the exhaust emissions. Various gasoline and detergents have different performances, having various impacts on the forming of CCD, which affects the engine performances and increases the exhaust emission finally. The effects of gasoline compositions as well as detergents on CCD are mainly summarized and some suggestions on clean gasoline development are proposed.
