Resumen
En el presente trabajo se selecciona y caracteriza el cultivo de la Higuereta como potencial proveedor de aceite vegetal con fines energéticos en las condiciones de Cuba, se evalúan tres alternativas de utilización del mismo: en su estado natural con precalentamiento, modificado a partir de la reacción de transesterificación en biodiesel y mezclado directamente con etanol, dada su capacidad de ser miscible
con el mismo por presentar grupos hidroxilo asociados a sus cadenas de carbono. Luego de definir la ultima alternativa antes mencionada como la más promisoria para nuestras condiciones, se estudia el comportamiento de la viscosidad de estas mezclas en función de la razón etanol/aceite y se selecciona aquella composición que según sus propiedades combustibles podría ser empleada en motores de
encendido por compresión con mejores resultados, analizando su influencia en los principales parámetros de funcionamiento de un motor Moto Cuba en banco de prueba.
In the present project selection and characterization of the cultivation of the Higuereta as a potential supply of vegetable oil as an energy resource under the conditions of Cuba, three alternatives of use of the same are evaluated: in their natural state with warm-up, as amended starting from the transesterificación reaction in biodiesel and blended directly with ethanol, given their capacity to be miscible with the same one to present groups hydroxyl associated to their chains of carbon. After defining the latter alternative mentioned before as the most promising for our conditions, the behavior of the viscosity of these mixtures are studied in function of the reason etanol/aceite and that composition is selected that could be employed in combustion engines by compression with better results according to its combustible properties, analyzing its influence in the main parameters of operation of a motor Moto Cuba in supporting bank.
