汽油车燃油蒸发污染物控制技术探讨

Discussion on Controlling Techniques of Fuel Evaporative Pollutant of Gasoline Automobile

随着汽车工业的发展,汽油车燃油蒸发污染物的排放已成为亟待解决的问题。为此,分析了汽油车燃油蒸发污染物产生的原因和危害,探讨了国内外汽油车燃油蒸发污染物控制技术的状况和存在的问题;并就我国最新公布的控制汽油车燃油蒸发污染物排放的法规要求,提出了发展汽油车燃油蒸发污染控制技术的新见解:控制从燃油的传输到汽油车使用全过程,抑制燃油蒸发和控制燃油蒸发污染物的排放,改进汽油车燃油蒸发污染物控制系统,以期达到环保和节能的目的。

With the development of automobile industry, the emissions of fuel pollutant evaporated from gasoline automobile are the questions which must be settled immediately. The origin and hazards of fuel evaporative pollutants of gasoline automobile were analyzed. The present conditions and the questions of controlling techniques of fuel evaporative pollutants from gasoline automobile at home and aboard we discussed. Aiming at the newly published codes of emission of evaporative pollutant from gasoline automobile, new proposal about developing controlling techniques of gasoline automobile evaporation pollution are put forward, i.e., overall processes control from fuel transport to vehicle in use, further restraining fuel evaporation and controlling emission of fuel evaporation pollutant, improving controlling system about fuel vaporization pollutant of gasoline automobile. Ultimately fuel evaporation pollutant will be reduced, the purpose of environment protection and energy saving will be achieved.
