Efecto sobre el consumo y los factores de emisión ante la implementación de un generador de hidrógeno como fuente de combustible adicional para un vehículo Great Wall M4 2017

Abstract

The main objective of this investigation was to analyze the effect of consumption and emission factors before the implementation of a hydrogen generator as an additional fuel source for a 2017 Great Wall M4 vehicle, carried out through road tests and a dynamometric bench to verify the contribution of engine performance. Therefore, a fan search was carried out on the incidence of hydrogen, in spark ignition engines, selecting the Plasmafire hydrogen generator through 3 independent route modalities: (City, Highway, and City - Highway) on the routes (Riobamba, Riobamba – Ambato, and Riobamba - Guano) under the NTE INEN 2204 emissions regulations. The data obtained by using the ELM327 connector equipment, and the MAHA MET 6.3 gas analyzer had correlated by using the Pearson coefficient and relative difference with a variation between operating conditions around 5% – 15%. It was possible to observe a reduction in fuel consumption and a reduction in the emission factor around 33%, 18%, and 16% respectively, and emissions, a reduction of 47% Hydrocarbons (HC), an increase in Nitrogen Monoxide of 14% (NOx) and Carbon Monoxide (CO) of 27% did not present considerable variations. For the validation, the student t statistic was used, with a significance level of 95%, concluding the addition of Hydrogen as additional fuel contributed to the reduction of polluting emissions and fuel consumption in the modalities: City and Road City.
