Estudio comparativo de emisiones contaminantes en vehículos ciclo diésel con el dispositivo plug & drive ECO OBD2 en el Distrito Metropolitano de Quito

Abstract

This project evaluated the effectiveness of the ECO OBD II device in reducing pollutant emissions from diesel vehicles. CO, CO2, O2,NOx and HC emissions were analyzed in three vehicles: Hyundai HDL36 4x2, Chevrolet D-Max 4x2 and Toyota Fortuner 4x2, with and without the use of the device. The results showed that the installation of ECO OBD II did not significantly improve emissions. Although a decrease in CO and HC was observed, the increase in O2 and variability in CO2 and NOx suggest that the device does not optimize combustion as advertised. Variations may be due to weather conditions and driving style rather than the device itself. The effectiveness of ECO OBD II is questionable, and factors such as the accuracy of the measurement equipment significantly affect the results. It is critical that the vehicle reach its ideal operating temperature to obtain accurate readings.
