摘要：A combined ultrasound and ultrahigh frequency electromagnetic treatment of the blended fuel, which consists of diesel mineral fuel (DF) and methyl ester of rapeseed oil (MERO), allows reducing viscosity of the biodiesel fuel. We experimentally examined the influence of ultrasound, ultrahigh frequency electromagnetic and mechanical treatment of blended biodiesel on its viscosity.It is established that the optimal treatment period for the blends of biodiesel fuel with ultrasound is 5 minutes that makes it possible to reduce viscosity of the product by 20 % on average. We also found a positive effect of UHF electromagnetic field on the blends of diesel fuel with methyl ester of rapeseed oil during for 5 minutes, which allowed us to reduce viscosity of the product by 5.6 % on average. A treatment of the blends of biodiesel fuel in a mechanical homogenizer did not lead to improvement in the fuel viscosity and, after 60 days of observation, viscosity remained at the same level as prior to the treatment.It was established that the combined effect of a 3-minute ultrasound and ultrahigh frequency electromagnetic treatment of the blend with 90 % DF + 10 % MERO and with 80 % DF + 20 % MERO made it possible to reduce viscosity of the biodiesel fuel by 16.3 % and 15.8 %, respectively, relative to the untreated blended fuel. Viscosity in the given blends, relative to the mineral diesel fuel, decreased by 9.3 % and 1.2 %, respectively.
