Análisis de emisiones en vehículos a gasolina utilizando pruebas estacionaria y dinámica mediante ciclo IM-240

Abstract

This study determine the emission factors for petrol vehicle using static and dynamic tests in vehicles that move in Quito city, for which statistically it takes into account the size of the most appropriate and representative sample of local vehicle fleet. Later, an experimental procedure is developed through test benches in order to get the variables used to calculate the static and dynamic factors, i.e. the pollutants concentration is measured using the two idle speed static cycle and IM-240 dynamic cycle respectively, then determine the fuel consumption utilizing the Quito drive cycle. Finally, the static and dynamic emission factors are compared in order to find a mathematical correlation that allow to get dynamic values based on static tests conducted locally.
