Summary. The aim of the study was to determine the effect of FAME bio-components on the dynamic viscosity of biofuels in temperature range of from -20 to 50oC. Six kinds of fuels have been prepared: B0 (clear Fuel Diesel), B20, B40, B60, B80 and B100. The value attached to “B” letter denotes volumetric proportion of AME (methyl esters obtained from animala’s fat) in the mixture with fuel oil. 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 0°C. Dynamic viscosity AME biofuels produced from pure animal fat in a temperature range of 50 to -20°C has a value of c.a. 15 to 150[mPa∙s]. Dynamic viscosity of Biofuel AME produced from animal fat consumed it was on average higher by about 5 to 10 [mPa∙s] of AME manufactured from pure fat.
