| Abstract | In response to emission control strategies, the mathematic model has been used to
generated emission factors and estimated emission inventory from on-road vehicle fleets.
Estimates of vehicle emissions are obtained by multiplying an estimate of the distance
traveled by a given class of vehicles by an appropriate emission factor. The emission factor
is defined as the estimated average emission rate for a given pollutant for a given class of
vehicles. Emission factors are based on vehicle descriptions, fuel quality, I/M programs
and environmental variables ; changes in those input parameters alter the resulting
emission factors.
The MOBILE 6 model approved by US-EPA in 2002 was calibrated appropriately to
calculate emission factors of each vehicle types in Thailand. Pollutants such as CO, HC,
NOx, and PM were measured on chassis dynamometer at the PCD's Emission
Labolatory.Input marameters to MOBILE6 were created and generated. Probabilistic
estimates of inter-vehicle variability, and of uncertainty in fleet average emissions were
developed, for a selected set of each motor vehicle type associated with the MOBILE 6
model. The implications of the emission factor uncertainty estimates for management and
repo1iing of emission inventories and for development of air quality management strategies
including a comparative between MOBILE 6 running and emission testing including
existing emission standard were discussed. The emission loading in BKK in the year 2004
.calculated by MOBILE6 are 49S ktons/year for NOx, 418 ktons/year for HC, 3,170
ktons/year for CO and S4 ktons/year.For the emission loading calculated from the emission
testing are 2,732 ktons/yesr for NOx, 3,090 ktons/yesr for CO, S,661 ktons/year for HC
and 127 ktons/year for PM. For SOx, the emission loading calculated by sulphure balance
equation is 16, 114 ktons/year. MOBILE6 emission factors are significantly different from
MOBILES emission factors with the reasons are differences in vehicle descriptions,fuel
quality ,I/M programs and environmental variables. |
