Análisis multivariado de las emisiones reales generados por vehículos livianos a gasolina bajo un ciclo de conducción urbano de la ciudad de Riobamba, año 2020

Abstract

The main objective of this degree work was to statistically analyze the real emissions generated by light gasoline vehicles under an urban driving cycle in the city of Riobamba, in the year 2020. With the use of the bibliographical exploratory type methodology, the information was taken from four databases, with different numbers of emissions of polluting gases each, taking into consideration 5 variables, 4 quantitative and 1 modifiable statistics. To reach the optimal results, a descriptive statistical univariate analysis was performed by using the free software R Studio; in contrast to the use of factor analysis, it was clearly evidenced that in the Chinese vehicle Cherry Nice, two factors were found in agreement to the number of emissions produced, the first factor composed of Carbon monoxide-Oxide of Nitrogen and the second factor Carbon Dioxide. In the Korean vehicle Hyundai Accent with two factors the first factor Carbon Monoxide-Carbon Hydrocarbons, in the second factor Carbon Dioxide-Nitrogen Oxides. In the German vehicle Audi the first Carbon Monoxide- Carbon Hydrocarbons and Nitrogen Oxides-Carbon Dioxide factor for the second factor. Finally, the Chevrolet Aveo Family vehicle assembled in Ecuador from same form composed of two factors, the first factor consists of Carbon Dioxide, Monoxide of Carbon and Carbonic Acid and the second factor composed only of Nitrogen Oxides. By performing the principal component analysis, results were obtained from the first component for each vehicle brand according to their polluting emissions, and it is concluded that vehicles from Korea, Germany and Ecuador have a low average of greenhouse gas emissions, on the contrary, the emissions of polluting gases produced by the vehicle from China are very high.
