Estudio desde un enfoque comparativo de emisiones contaminantes en vehículos equipados con motor ciclo OTTO y dispositivo ECO OBD2 en el Distrito Metropolitano de Quito

Abstract

In this study, a comparative analysis of pollutant emissions in vehicles equipped with Otto cycle engine and ECO OBD2 device in the Metropolitan District of Quito was carried out. The impact of the increase of vehicles on environmental pollution was examined and the use of the pollutant emission reduction device was proposed. The materials and methods used were detailed, including road tests and the Eco OBD2 device. In addition, the technical vehicle inspection regulations and the operation of the catalytic converter in vehicles were discussed. The study included road tests to analyze the impact of the device on vehicle pollutant emissions. It will be observed that, in some cases, when the device was connected, there was an increase in unburned hydrocarbons, but there was no significant reduction in the gases mentioned. The results of the tests are presented in tables and figures for each vehicle and type of revolutions. In addition, the impact of the device on pollutant gas emissions in vehicles at different revolutions was evaluated. It was observed that the interface does not significantly reduce emissions, except in vehicles with defective catalytic converters. On-road measurements and measurements on a variety of vehicles are recommended to evaluate its optimal performance. The study also included bibliographic references related to the subject.
