| 摘 要： | 通过对影响汽油车加油排放的外界环境（雷德蒸汽压）、裹入的空气速率和油箱的温度以及蒸发质量分数等主要因素进行分析,发现加油排放速率随空气的裹入速率和油箱的温度的变化呈线性关系;在给定的蒸发质量分数的条件下,汽油蒸汽压力的自然对数与温度的倒数呈线性关系;通过比较发现,车载汽油蒸汽回收装置的回收效率达93.9%以上.研究结果表明,可以通过降低雷德蒸汽压、降低空气的裹入速率和油箱的温度等途径来实现减少加油过程的排放.

| Abstract: | Analysis of main factors impacting on refueling emissions was studied including outside environment(RVP),the air entering speed rate,tank temperature,and the evaporated mass fractions.It shows that the refueling emission represents linear relation with the change of the air entering speed rate and tank temperature and the vapor pressure of fuel and temperature relationship at the fixed evaporated mass fraction,this can be represented by straight lines between the vapor pressure of fuel and inverse temperatu... |
