| Abstract | The mobile sources emission inventory was updated for Bogota city. Emission factors were deter- minate by means of a novel field campaign not performed before in any other Colombian urban center. More than 200 direct emission measurements from vehicle exhausts under real conditions were performed. Real-time in- struments were used for on-road measurements. Monitored vehicles were powered with gasoline, ACPM and natural gas. According to these results, mobile sources of Bogota annually emit: 4,800,000 tons of CO2; 450,000 tons of CO; 30,000 tons of NOx; 60,000 tons of THC and 1,100 tons of PM2.5. For CO, THC and NOx, vehicles equipped with tree-way catalysts exhibited much lower emissions than those lacking such a technology. In gener- al, vehicles with larger engines exhibited higher emissions than those vehicles with smaller engines. Additional measurements were performed on dual vehicles (gasoline - natural gas). These results suggest there is no envi- ronmental benefit in regards of the reduction of pollutant emissions, when a vehicle is transformed from gasoline to natural gas. In addition, tests were developed to asses PM emissions reduction while vehicles powered with conven- tional ACPM and then with low sulfur ACPM. Reductions of PM emissions up to 60% were found. |
