摘要

Motor vehicle emission factors of CO, NOx and nonmethane hydrocarbons (NMHC) were measured inside the Chung-Cheng Tunnel of Kaohsiung in Taiwan. The results were compared with the corresponding values calculated by Mobile Taiwan-1.0 and Mobile-5b models. Concentrations of individual hydrocarbon species were also determined, and reactivity of organic species from motor vehicles calculated through use of MIR scale. Results show that the average emission factors of CO, NHMC, and NOx inside the Chung-Cheng Tunnel were 6.25, 1.51, and 1.02g/veh-km, respectively. The error range of the emission factors was 45%. Concentrations of isopentane, 2-methylpentane, benzene and toluene are the dominant species. Emission factors predicted by Mobile Taiwan-1.0 were much higher than those actually measured. However, values predicted by Mobile-5b did closely match the observed data. The MIR/VOCs ratios found inside the Tunnel differ significantly from those reported for Fort McHenry Tunnel and Tuscarora Tunnel, which is probably due to difference in driving patterns and fuel compositions.
