Abstract. The aim of the study was to compare the impact of dynamic viscosity of two biofuels. One was a mixture of 50% (m / m) SBME and 50% (m / m) RME of own production. The mixture was conventionally called FAME. The second biofuel was commercial RME from a gas station.
Dynamic viscosity as a function of temperature from -20 to 50oC was tested. The main device used at the measuring stand was ReolabQC rheometer manufactured by a German Anton Paar GmbH company. Dynamic viscosity especially grew rapidly after cooling biofuels to temperatures below -5°C. Dynamic viscosity FAME biofuels produced from pure vegetable oil (soybean oil and rapeseed oil) in a temperature range of 50 to -20°C has a value of c.a. 9 to 53[mPa∙s]. Dynamic viscosity of Biofuel FAME produced from mixtures of vegetable oils it was on average lower by about 1 to 8 [mPa∙s] of RME shopping from a gas station.
