- Experimental study of ozone-forming potential from exhaust emissions of vehicles fueled with reformulated gasoline in Mexico City J. Luis Jaimes-López Julio Sandoval-Fernández Emmanuel González-Ortíz Angel Zambrano-García Martín Llanos-Plata Uriel González-Macías Ciencias de la Tierra ozone smog chamber exhaust emission forming potential reformulated gasoline 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. 2006 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37022403 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.4 Vol.22
