Comparación de factores de emisión vehicular al utilizar ciclos de conducción IM240 y on board en la ciudad de Quito

Abstract

This article describes a method for obtaining factors vehicular emissions, using the simplified model of combustion applied to two different driving cycles. The first of them is IM240 (cycle route simulation using a dynamometer) and the second one is an on board cycle (real cycle route in city roads and highways), for which, the concentrations of emissions and fuel consumption were measured for each cycle. The aim of this study is to prove that the real factors, CO, HC and NOx, obtained from On Board cycle, can be measured in a simulated cycle on a dynamometer through the introduction of adjustment factors such as for EFCO(Route)=0,442 + EFCO(IM240), EFHC(route)=0,012+ EFHC(IM240), and EFNOx(route)=0,049 + EFNOx(IM240). This research was conducted in 5 vehicles to prove that is statistically reproducible and has a high reliability equal to the 95% of measurements taken in each procedure.
