Estudio comparativo de torque y potencia en vehículos categoría M1 equipados con un dispositivo ECO OBD2 en el Distrito Metropolitano de Quito

Abstract

This document refers to the variation obtained in torque and power of an engine implementing a pollutant gas reduction device. The methodology of this study involves three gasoline vehicles from different brands with a similar engine displacement. The latter parameter was not established as fixed since the test device, according to the manufacturer's recommendations, works in any vehicle regardless of the engine displacement. The tests under which the analyzed data in this document were obtained correspond to those of an automotive dynamometer and driving tests on two urban routes localized in the Metropolitan District of Quito. The driving style, type of fuel, and other aspects that can alter the results were considered and detailed with the aim of achieving homogeneity for the analysis of the parameters of interest. The performance of the engines in the vehicles evaluated are influenced by the presence of an external device. The dynamometer tests showed variation percentages ranging from 0.5% to 12.59%. The road tests show variations for the parameters of interest in their respective units both in whole figures and in decimals.
