Análisis de emisiones de escape del motor de encendido provocado de vehículo del segmento a, en condiciones de simulación de ciclo estándar de conducción en ciudades de altura

Abstract

Based on previous studies of gas emissions worldwide, this project aimed to analyze the emission factors originated by Super and Extra fuels in the best-selling brand in the Sierra region 2019 Kia Picanto vehicle. It was tested in a dynamometer (DYNOCOM) under the IM240 driving simulation characteristics. The MAHA gas analyzer and a LIQUI MOLY pressurized container were also used to evaluate the performance and contamination margin to evaluate which fuel has the highest percentage of contamination and which has the best performance under the altitude condition 2754 meters above sea level in the city of Riobamba. Once the CO, HC, and NOx emission factors for each fuel (g/km) were estimated. The STATGRAPHICS software performed the statistical analysis, and with the analysis of variance (ANOVA) and the least significant difference procedure (LSD), Fisher's determined a representative difference in CO generation for both fuels. But with similar behavior for HC and NOx at a 95% confidence level. It concluded that the usage of Super fuel reduces the CO emission value by 30% compared to Extra, whose average amounts of emission factors are FCO 3.32 g/km, FHC 0.08 g/km, and FNOx 2.25 g/km. In the case of Extra fuel, the values are FCO 4.80 g/km, FHC 0.10 g/km, and FNOx 2.24 g/km. In addition, the performance of the operating liquid is more efficient with the Super fuel, with an additional 11% in its autonomy, as it is of better quality. It is recommended the creation of an inventory of emissions carried out under Ecuador's control standards because of the lack of a database for this analysis.
