Análisis comparativo basado en el rendimiento de un vehículo segmento B con y sin aditivos en la mezcla de combustible extra de 87 octanos

Abstract

The objective of this research was to determine the differences through a comparative analysis between the existing performance of a sample of four Chevrolet vehicles using eighty seven octane fuel without additives. Two types of tests were carried out for it, one dynamic and the other static. For the first, a 16.5 km route was proposed in altitude conditions from 2,900 meters above sea level to 3,550 meters above sea level. Speed and resolutions during the driving cycle, an ELM 327 scanner and the "Torque Pro" application were used to obtain real data on consumption. While for the static test using a KANE brand gas analyzer, the percentage values of the exhaust gases such as CO, CO2, O2 and HC were obtained, being evaluated at the end of each dynamic test. Based on this, there was a total of sixteen tests, eight without additive, in which their results were applied in the Minitab statistical program allowing the use of methods such as Fisher, the same one that had a reliability factor of 99%, this with the interest of knowing comparisons between the two states of vehicles. Among the results, a positive response was obtained in terms of fuel efficiency, so that three out of four vehicles showed a higher performance while in exhaust gas emissions there was no clear trend. In conclusion, it was determined that the effect is independent in each vehicle according to its state, it means, years of life, and maintenance care, among others, and that the additive did generate changes in behavior, but it was not decisive for optimal performance. In turn, it was recommended to be specific with the conditions in which the vehicles will be tested in order to obtain more reliable results.
