Mathematical Model to Predict the Otto Cycle Vehicles Exhaust Emissions from Automotive Gasoline Composition 2004-01-2902

In the last decades, PETROBRAS has strongly contributed to improve its gasoline quality to attend engines and environment regulations evolutions.
In this context, PETROBRAS Research and Development Center (CENPES) has been performing repeated evaluation studies about the influence of the gasoline properties in the pollutant emissions (THC, CO, NOx, Aldehydes and CO2).
This paper presents the statistical modeling study made by Vehicles Test Laboratory at CENPES that allows predicting these pollutants, from gasoline composition variation, mainly the aromatics, olefins and sulfur contents.
