Abstract
Keywords: biofuels, lucubration, viscosity
The Department of Automobiles at the Technical University of Budapest has been searching the possibilities of using alternative fuels for a long time. The target vehicle of this investigation, a flexible fueled vehicle (FFV) has a single fuel tank, fuel system, and engine. The vehicle is designed to run on diesel oil and a mixture of bioalcohol, biodiesel and diesel oil, containing up 20% of biofuel. The engine and fuel system in a flex-fuel vehicle must be slightly adapted to run on bioethanol-biodiesel-diesel oil blends, as the biofuels are more corrosive. The vehicle running with the investigated blends offers its owner an environmentally beneficial option whenever the alternative fuel is available.
