Análisis de emisiones contaminantes en vehículos de categoría M1, equipado con el dispositivo ECO OBD 2, con y sin convertidor catalítico mediante pruebas dinámicas dentro del Distrito Metropolitano de Quito

Abstract

The present study carries out a comparative analysis of pollutant emissions in category M1 vehicles, with and without catalytic converter, equipped with a pollutant emissions reduction device (ECO-OB2). The methodology of this study was carried out with the help of the portable gas analyzer (KANE-EGA-5). Three Otto cycle engine vehicles were used, and general maintenance was performed to ensure that all components were in optimal condition and did not affect data collection. Dynamic tests were carried out on urban and rural routes within the Metropolitan District of Quito. The test results are presented in figures and tables for each vehicle, evaluating the impact of the device without a catalytic converter. This analysis was carried out due to the increase in vehicles and high emissions of toxic gases, such as carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbons (HC), which affect people's health.
