Effect of the Rapeseed Oil Methyl Ester Component on Conventional Diesel Fuel Properties

Open access


The effect of the rapeseed oil methyl ester (RME) component in diesel fuel was assessed. Dynamic viscosity and density of blends were particularly observed. Measurements were performed at standard constant temperature. Increasing ratio of RME in diesel fuel was reflected in increased density value and dynamic viscosity of the blend. In the case of pure RME, pure diesel fuel, and the blend of both, temperature dependence of dynamic viscosity and density was examined. Considerable temperature dependence of dynamic viscosity and density was found out and demonstrated for all three samples. This finding is in accordance with theoretical assumptions and literature data sources. Mathematical models were developed and tested. Temperature dependence of dynamic viscosity was modelled using the 3rd degree polynomial. Temperature dependence of density was modelled using the 2nd degree polynomial. The proposed models can be used for flow behaviour prediction of RME, diesel fuel, and their blends.
