Development of a fuel consumption measurement methodology for light duty vehicles in Colombia, based on metrology principles

espanolEn este trabajo, se elaboro una metodologia para medir el consumo de combustible para vehiculos livianos (LDV) en Colombia, basandose en las metodologias existentes para el transporte por carretera en todo el mundo. Esta metodologia se propuso como una herramienta para la evaluacion de estrategias de eficiencia energetica aplicadas en vehiculos, asi como para establecer la linea base para medicion, control y regulacion del consumo de combustibles fosiles con base en criterios metrologicos. Ademas, se analizaron las capacidades de medicion dentro de Colombia y se adoptaron los procedimientos establecidos por el Codigo de Regulaciones Federales de los Estados Unidos de America, para medir el consumo de combustible de LDV por metodos gravimetricos. Se elaboro un modelo de incertidumbre basado en la Guia para la expresion de la incertidumbre en la medicion (GUM), y se analizo la contribucion de diferentes variables asociadas al proceso de medicion, instrumentos, equipos y condiciones ambientales sobre la incertidumbre del mensurando EnglishIn this study, a methodology to measure fuel consumption for light duty vehicles (LDV) in Colombia was elaborated based on existing methodologies from road transportation worldwide. This methodology was proposed as a tool for the evaluation of energy efficiency strategies applied to vehicles, as well as establishing the baseline for measurement, control, and regulation of consumption of fossil fuels based on metrological criteria. Additionally, the capacities for measurement within Colombia were analyzed, and procedures stated by the Code of Federal Regulations of the United States of America were adopted for measuring fuel consumption of LDV by gravimetric methods. An uncertainty model based on the Guide to the expression of Uncertainty in Measurement (GUM) was elaborated, and the contribution of different variables associated to the measurement process the instruments, the equipment, and the ambient conditions over the uncertainty of the measurand, were analyzed
