燃油在运输、储存和加油过程中,都可能有水进入。燃油中的水,主要是当温度波动很大时,汽车油箱和储油罐内空气中的水蒸汽,在容器内壁凝聚而进入油内。当燃油温度升高时,水在燃油内的溶解度增加。例如,当煤油的温度由15℃增加到17℃时,其中水的溶解度相应的由0.006%增加到了0.04%。当燃油变冷时,溶解在燃油中的部分水以第二相的形式分离出来,首先是尺寸小于1微米的乳胶状水粒子,然后聚集成水滴,在
Fuel may enter water during transportation, storage and refueling. The water in the fuel is mainly when the temperature fluctuates greatly, the water vapor in the air in the fuel tank and the storage tank condenses into the oil in the inner wall of the container. As the fuel temperature increases, the solubility of water in the fuel increases. For example, as the temperature of kerosene increases from 15 ° C to 17 ° C, the water solubility increases correspondingly from 0.006% to 0.04%. As the fuel cools, part of the water dissolved in the fuel separates out in the form of a second phase, first of all latex-like particles of water less than 1 micron in size and then collects into water droplets
