Análisis comparativo de dos estrategias para la medición de consumo de combustible y validación de las mismas en un dinamómetro

Abstract

This project comprises a comparative analysis of two strategies. The first strategy dealt with the use of a flow sensor and, the second applied mathematical formulas for the measurement of fuel in light cars with gasoline and injection engines. Through the implementation of a prototype, whose control and processing is carried out with an Arduino programming card, with connection to the LabVIEW software, for the visualization of data in real-time. Data validation was carried out with the support of a dynamometer. The functional tests were carried out on a Mazda automobile, model 60002. This selection was justified because it is one of the most used vehicles in the last five years. This project proposes a new way to measure fuel consumption, representing an approximation to its real value, considering non-optimal conditions in vehicle handling, such as unstable roads, frequent accelerations, wear and tear due to the use of the vehicle, among others. The development of the project has been based on apprehensive and integrative research methodologies descriptive, comparative and confirmatory in its empirical modality, considering that both the analysis and the information gathering were carried out automatically employing data processing software. With the results provided by the system, it is demonstrated that the second strategy is the optimal one for calculating fuel consumption, giving a minimum error of 4% with a frequency of 30 hertz, comparing with the dynamometer. In the second stage of the project, it is recommended to use new and precise strategies to be able to verify the fuel consumption in the vehicle. Or to improve one of the strategies by acquiring exact sensors.
