There are currently numerous scientific papers and researches have highlighted the importance of physical properties of bio fuels in optimal functioning of the equipment of injection of internal combustion engines. Properties as viscosity, density and calorific value were considered to be the most important and relevant to current studies and surveys on the use of bio fuels. However, the multitude of researches carried out (both at national as well as internationally) were used as experimental apparatus, the apparatus allowing only change the physical characteristics of property only in terms of atmospheric pressure or in conditions existing inside the combustion chamber. This paper proposes a new approach through the use of research facilities based on the principle of ultrasonic measurements, possibly carrying out such experiments (and the issuance of necessary conclusions) in accordance with the terms of the functional internal combustion engine powered by bio fuel. Establishing the exact physical properties of bio fuel based on functional factors opens the way to new research related to increasing energy efficiency of internal combustion engines fuelled by bio fuel, with the possibility of practical realization of electronic systems (a "flex fuel cell") that allow adaptation functionality injection system with quality bio fuel (fuel) use.
