Evaluation of the performance in fuel consumption and polluting emissions of the segment A vehicle, applying the IM 240 cycle simulation in the city of Riobamba.

Abstract

Based on previous studies of gas emissions worldwide, the objective of analyzing the emission factors caused by Super and Extra fuels in a segment A vehicle started, which will be tested on a dynamometer, lowered the IM240 driving simulation characteristics, the MAHA gas analyzer was also used, and a pressurized container to evaluate the performance under the condition of 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 statistical analysis was performed using the STATGRAPHICS software, where with the analysis of variance (ANOVA) and the least significant difference procedure (LSD) Fisher's. It was determined that there is a representative difference in the generation of CO for both fuels, but with a similar behavior for HC and NOx with a confidence level of 95%. In addition, the performance of the working liquid is more efficient with Super fuel, with an additional 11% in its autonomy.
