Determination of the rheological properties of biofuels containing CME biocomponent

Similarly to diesel oil (B7), Biodiesla B100 CME dynamic viscosity at positive temperatures in principle increases with decreasing temperature. Having exceeded 263K, it begins to increase rapidly. The dynamic viscosity for B100 CMEat 253K was 204 mPa×s, for B75 CME - 118mPa×s , for B50 CME - 77mPa×s and for B20 CME - 42mPa×s. The study has shown that B100 CME cannot be used in practice as a pure fuel without a package of viscosity-lowering additives. At the same time, the viscosity values for B5 and B20 biofuels, in particular at positive temperatures, are close to the viscosity of diesel fuel. Under such conditions one can safely use B7 and B20 biofuels in compression-ignition engines, even in those with a state-of-the-art injection apparatus.
