Emisiones de gases contaminantes en vehículos livianos a gasolina

Abstract

The main objective of the study was to determine the emissions of polluting gases in light gasoline vehicles of the automotive fleet of the Technical University of Manabí, Portoviejo, Ecuador. As a methodology, a quantitative approach to the research was applied, through a quasi-experimental design, using the technique of observation supported by technological instruments to collect data from the object of study, such as the gas analyzer, to later process the information in graphs and tables; The population sample was made up of 10 gasoline vehicles, of which 8 correspond to the 2000s onwards and 2 to the 90s, according to the NTE INEN 2204 regulation. The types of polluting emissions produced by the vehicles were obtained as results. of both decades, during the static test and the dynamic test, achieving compliance with the pollutant emissions parameters established by the NTE INEN 2204, except for the data of a single vehicle (1% of the sample) that did not comply with the regulations, whose manufacture corresponds to the 90s. It was possible to conclude that the resulting values ​​are the product of the conditions of the vehicle's engine and its extended useful life given the maintenance provided in the maintenance centers.
