Resumo: |
The stability of a fuel is critical to providing better engine performance. The biodiesel derived from babassu stands out in relation to this feature. Thus, we sought in this study comparing the effects of the mixture of hydrated ethanol and absolute ethanol with biodiesel in variable proportions of 10, 20 and 30% ethanol (absolute and hydrated) by volume performance in the motor generator diesel cycle direct injection and on some physical and chemical characteristics. Among these, they analyzed properties such as viscosity and density, which are characteristics that influence the spark. And beyond these, the calorific value of the mixtures was also determined. Subsequently, biodiesel blends/hydrous ethanol and biodiesel/anhydrous ethanol to concentrations of 10%, 20%, 30%, 100% biodiesel babassu oil and diesel fuel were tested in diesel cycle engine, which evaluated the consumption of fuels (mL), volumetric consumption, generated load and energy efficiency with variations of resistive loads of 1.5, 3 and 4.5 kW. The physicochemical properties of biodiesel contribute to the assessment of the established parameters for better quality biodiesel. And the viscosity and density analysis is influential on the combustion of mixtures in the engine. The high calorific value (PCS) for all treatments with the use of each, it follows that the PCS no influence on consumption. The variation of the resistive load caused a change in motor behavior and motor generator system as a whole. The highest efficiency obtained for mixtures was resulting in effective charge of 4.5 kW for mixtures of B80E20 (hydrated ethanol: 12% less efficient than biodiesel) and B80E20 (absolute ethanol: 10% less efficient than biodiesel). The application of ethanol with an additive to biodiesel helps reduce the use of fossil fuels. |
