Análisis de un modelo de predicción del consumo instantáneo de combustible basado en señales de los sensores del sistema de inyección para el automóvil Chevrolet Aveo Family 1.5L.

Abstract

The present work was for titling was carried out based on the need to reduce the fuel consumption of the MCI, gasoline, especially in taxis, the main objective work was to analyze a fuel consumption model of MCI, gasoline, which informs to the driver about the fuel consumption at every moment to reduce fuel consumption depending on the way of driving, therefore a Chevrolet Aveo Family 1.5 vehicle was used to carry out the different tests of consumption, both real and theoretical, to implement the different signals of sensors of the electronic injection system that will serve as a basis for the determination of the model of prediction of fuel consumption of the MCI, to gasoline in order to inform the driver about fuel consumption. By using the theory of ideal gases, stoichiometry mix and volumetric performance, the theoretical fuel consumption equation was determined. For the determination of instantaneous fuel consumption, the engine speed was included in the fuel consumption equation of the M.C.I, to gasoline that predicts the projected fuel consumption in gallons per hour. To determine the reliability of its results of the MCI fuel consumption prediction model, a statistical method was applied that compared the consumption of the prediction model with the theoretical consumption of the vehicle and the actual consumption of the vehicle, resulting in an error within the admissible, reason why it is determined that the model of prediction is reliable, therefore, it is concluded that this model is reliable and applicable to other vehicles of MCI, to gasoline having considerations in modifying several parameters.
