Some typical types of biofuels widely known today include: bioethanol (bioetanol), biodiesel (biodiesel), green diesel (diesel), biological kerosene (biokerosen-or reactive fuel). biological forces), other biological alcohols (methanol, butanol), bio ether, biogas, synthetic gas, solid biomass fuel. In fact, the two most important biofuels are bioetanol and biodiesel, because of the many properties they have: use for the two most common types of vehicles (gasoline and motor vehicles). diesel engine); has many properties similar to fossil fuels, but cleaner and cleaner; produced from abundant and renewable materials such as sugar, starch and animal and vegetable fats and oils. The paper presents results obtained from a method applied for improving the properties of pure bio-oil aiming a direct use as a fuel in conventional diesel engines. Some typical properties such as high viscosity, high surface tension, high density and high cloud point are considered to be improved within this study. Characteristics of the viscosity, density and the surface tension versus fuel temperature are established. Findings of this study provide a basis for calculation and design a heating system of bio-oil fuel and for improving some typical properties of this fuel in order to use directly in diesel engines of small generator sets or diesel engines used in agriculture, forestry fields or in small boats.
