The Study on the Influence of Factors on Vehicle Refueling Emission Test

Two vehicles with onboard refueling vapor recovery (ORVR) system which are met with the US standard were studied. A comparison of refueling emissions test under different refueling rate and different refueling temperature were studied. The hydrocarbons (HC) chemical analysis was carried out for the fuel gas emission from a sample car. The results show that with the increase of the refueling rates, the refueling emissions decline at first, and then gradually stabilize; with the increase of the refueling temperature, the results of refueling emissions show a gradual increase. Under the condition of 37 L / min refueling flow rate and 20 °C fuel temperature, 14 kinds of alkanes are emitted from the fuel, in which isobutane, isopentane and n-pentane are the highest emissive components, accounting for 57.66% of the total amount of volatile organic compounds (VOCs).
