| 摘 要： | INTRODUCTION Motor vehicles continue to be the dominant source of air pollution, despite tremendous advances in engine technology and pollution control. Vehicles are significant sources of CO, HC, and PM and comprise one of the most important sources of NOx, which along with HC, are the essential precursors of ground-level ozone. In view of emissions harm to human health, major efforts to control them have been made, both through improved emission control technologies and through gasol…

| Abstract: | The largest urban areas of Mexico cities have witnessed high levels of air pollution in the past few decades. The most important
air pollutants are ozone and particulate matter with levels that are still far above current air quality standard. In this
work we studied exhaust and evaporative emissions of Mexico City metropolitan area (MAMC) vehicles using fuels in which sulfur
content was varied from 89×10−6 to 817×10−6, and calculated the ozone forming potential of emissions as well as the specific reactivity of the exhaust for each average
fleet-fuel combinations. Data on emission levels were compared to those obtained in 2000 for the same vintage of vehicles.
The almost twofold increase in emissions found could be due to degradation of the exhaust emissions control systems. |
