An Experimental Study of ORVR Refueling Emission Based on China VI Standard
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.
