| Resumo: | Several experiments using outdoor smog chambers were carried out to determinethe ozone-forming potential from exhaust emissions of reformulated gasolines comparedwith a reference gasoline. The objective of this experimental study is to selecta reformulated gasoline which has the lowest impact on ozone formation, by usingautomobiles equipped with technology that complies with the Euro4 regulation. Thisgasoline will substitute the one used in vehicles technologically equipped to complywith the Tier 1 regulation in México City. The smog chamber method showed that thereformulated gasoline with the lowest impact on ozone formation, in automobiles thatcomply with Tier 1, was F3, and the one for Euro4 vehicles, was F5. These gasolineshave lower benzene and sulfur concentrations than the reference gasoline used in theexperiments. Also, after 9 runs carried out in a dynamometer and using the referencegasoline in both types of automobiles, the one equipped to comply with Euro4 emittedless pollutants (mg/km) and toxic species to the atmosphere, than the one equipped tocomply with Tier 1. This is a preliminary study, and it is necessary to carry out furthertests with these fuels using representative vehicles of the MCMA, with and withoutcatalytic converter. |
