【 摘 要 】

The paper presents results of the research focused on stability of diethyl ether/rapeseed oil blends. Rapeseed oil (RO) and diethyl ether (DEE) are cheap, oxygenated fuels which are produced from renewable sources. Rapeseed oil is not the most appropriate fuel for diesel engines but addition of DEE significantly improves same physicochemical properties of the blend. On the other hand due to the low polarity and low density of DEE compared with RO, it is possible that such mixtures can be unstable. For this reason, in this research a stability of DEE/RO blends was empirically examined using a Turbiscan Lab research equipment. Necessary tests were carried out during 28 days of measurements. In particular a RO with addition of 10, 20, 30 and 40 % by vol. of DEE has been tested. Results confirm that RO/DEE blends constitute stable one phase and transparent mixtures without any symptoms of fluids stratification.
