摘　　要：分析了汽车加油过程中汽油蒸汽排放量测量的试验方法,设计了一套用于检测加油过程汽油蒸汽排放的收集设备,介绍了设备的基本组成和工作原理,在平均温度为25℃和雷德蒸汽压为62kPa的条件下进行了3组试验,测量了汽油车加油过程中的油气蒸发量。试验结果表明:安装活性炭罐但未安装车载油气回收系统(ORVR)的检测系统,能够减少15.7%的加油过程排放;而当同时安装活性炭罐和ORVR后,能够减少93.9%的加油过程排放。In order to measure the gasoline vapor emission quality in refueling process,the experimental methods of gasoline evaporation loss were studied,and a collection equipment was designed.The basic components and working principle of the equipment were introduced.Under the condition that average temperature was 25 ℃ and RVP（Reid vapor pressure）was 62 kPa,three experiments were operated.The result shows that for the detection system with carbon canister but without ORVR（on-board refueling vapor recovery）,refueling emission reduces by 15.7%.However,while installing carbon canister and ORVR,refueling emission reduces by 93.9%.4 tabs,7 figs,13 refs.
