Algoritmo de predicción del consumo de combustible para mezcla de etanol anhídrido en ciudades de altura

In the present research work, a mathematical model is obtained for predicting specific fuel consumption in a 1.4-liter Otto cycle engine with electronic injection without making modifications, when using as fuel gasoline mixtures with concentrations in volume of 0 %, 25 %, 50 %, 75 % and 100 % of anhydrous ethanol. For the analysis of results, a simplex lattice reticular mixture experiment design was carried out, which was subject to an urban driving cycle in the city of Cuenca at 2558 m above sea level in a roller power bank. The data acquisition and the development of the algorithm were carried out through an analysis of descriptive statistical methods. The validation of the algorithm was performed through residual analysis. As a main result, there is a mathematical model that enables predicting the engine fuel consumption, for ranges of ethanol concentration from 0 % to 100 % in the gasoline without needing to conduct real tests.
