摘要
对某满足国六排放限值的车载油气回收系统(ORVR)用美国OPW加油枪和德国ZVA加油枪分别进行加油排放试验,并采集加油过程通气管流量、回气管流量、油箱压强和炭罐增重量的数据.结果表明,ZVA加油枪加油时的通气管流量、回气管流量、油箱压强和炭罐增重量均比OPW加油枪加油时的小,在国六燃油系统开发过程中,调整回气管限流阀孔径和对炭罐脱附进行标定时应考虑不同加油枪的影响.
An on-board refueling vapor recovery（ORVR） system that meets the emission limits of China VI regulation is tested with three refueling emission experiments respectively with OPW refueling gun and ZVA refueling gun, and data of flow of air pipe, flow of circulation pipe, tank pressure and canister weight increments are collected. The results show that the flow of air pipe, flow of circulation pipe, tank pressure and canister weight increments of ZVA refueling gun are less than those of OPW refueling gun when refueling. In the China Ⅵ fuel system development process, while adjusting the aperture of flow-limiting valve on circulation pipe as well as calibrating the canister purge, the effect of different refueling guns should be considered.
