Authors Abstract
Content
In 2005, it was published a paper in Brazil reporting significant values of aldehydes emissions for some old Brazilian diesel SUVs (Sport Utility Vehicles). In 2008, PETROBRAS (Brazilian Oil Company) together with LACTEC (Institute of Technology for Development) decided to study methods for measuring aldehydes from diesel vehicles, including SUVs and heavy-duty engines.
In 2008, National Environmental Council (CONAMA) published legislation 408/08, establishing that IBAMA (Brazilian National Environmental Institute) must provide a procedure for aldehyde measurement at the end of December 2010 and that engine manufacturers must report typical aldehyde emission values of diesel vehicles before the end of December 2012.
A technical group was created in 2009 by the Brazilian Automotive Engineering Association (AEA) to discuss and elaborate a new method for aldehyde measurement in diesel vehicles and heavy-duty engines. The new procedure must be published before the end of 2010.
This paper will present a bibliography review of aldehyde formation in diesel vehicles and will show some proposal methods studied by PETROBRAS and LACTEC to measure these pollutants, including the use of HPLC (High Performance liquid Chromatography) and FTIR (Fourier Transform InfraRed Analyzer).
