Resumen
El objetivo del presente trabajo es la obtención de algunas propiedades físico-químicas de varios combustibles, las cuales son importantes a la hora de simular el sistema de inyección en los motores diésel. Para ello se han estudiado tres propiedades fundamentales: densidad, viscosidad y tensión superficial. Los ensayos se han realizado para gasoil y biodiesel, así como para distintas mezclas de biodiesel con etanol. La tensión superficial juega un papel muy importante en la evolución de los parámetros de la inyección del combustible, así como en la formación del chorro, sin embargo, es una propiedad de la que no existe información en la revisión bibliográfica consultada. Es por esto que el estudio experimental llevado a cabo supone un avance en la investigación.
The objective of this work is to obtain some physical-chemical properties of various fuels, which are important when simulating the injection system in diesel engines. For this, three fundamental properties have been studied: density, viscosity and surface tension. The tests have been carried out for diesel and biodiesel, as well as for different mixtures of biodiesel with ethanol. Surface tension plays a very important role in the evolution of the fuel injection parameters, as well as in the formation of the jet, however, it is a property for which there is no information in the bibliographic review consulted. This is why the experimental study carried out represents a breakthrough in research.
