车用汽油长期储存后的使用

How to Use the Long-term Stored Automobile Gasoline

汽油在长途运输、长期储存及多次换装过程中,个别质量指标会发生变化,如汽油的馏程发生变化,辛烷值降低及实际胶质含量增多等,在使用中应特别注意。汽油在长期储存过程中应注意①减少轻组分的蒸发和延缓氧化变质;②饱和储存,减少气体空间;③避免与铜或其它金属接触;④防止水杂对油品的污染;⑤坚持储存化验,建立汽油质量档案。

The individual quality indexes of automobile gasoline such as distillation range,octane value and existent gum will change owing to the long distance transportations,long-term storages and frequent loadings/ unloadings. The paper considered that the attention should be paid to the gasoline when long-term storing in below aspects:(1) reducing light component's loss and delaying oxidation; (2) full load storing to reduce the air space;(3)avoiding contacting with copper or other metals;(4)pveventing the gasoline from contaminating by water and foreign substances;(5)conducting regular chemical examination and setting up a quality record.
