Motor gerador operando com diesel e biodiesel de nabo forrageiro

Abstract

This study aims to present the potential use of biodiesel from forage radish (Raphanus sativus L) as fuel in diesel engines. In the experiment, an 8.0 kVA diesel generator engine was used, fed with resistive loads of 1,000 W, 1,500 W, 4,500 W and 6,000 W. Performance and environmental impact were evaluated through the gases emitted. The experiment was conducted at the Laboratory of Sustainable Technologies of Unioeste, Campus of Cascavel - PR. The treatments used were: diesel of fossil origin, pure, without addition of biodiesel, and pure turnip biodiesel. The biodiesel had higher flash point, lower presence of total aromatics and benzene, higher content of esters, total olefins and toluene, higher freezing point than diesel and no water and sediment residues. The generated energy remained increasing and stable as the load increased. The analyses showed variations in consumption as a function of loads, reduction in CO and NOx emission, zero HC emission and increase in CO2 emission with the application of higher loads. The results showed that forage radish biodiesel presented itself as a viable solution for use in diesel engines, without the need for structural changes in the engine.
