heal.abstract	The lubricating efficiency constitutes an important property of diesel fuel since several diesel engine parts, such as pumps and injectors, are lubricated by the fuel itself. The aim of the project was to investigate the alterations in the lubricating properties of oxidized FAMEs and Diesel/FAME blends. Two different types of FAMEs (without antioxidant additive) were blended with Ultra Low Sulfur Diesel Fuel (ULSD) at concentrations of 5%, 10% and 20% v/v and the samples were subjected to oxidation. Oxidation stability measurements were carried out by Rancimat accelerated oxidation method, according to European Standard EN14214. A High Frequency Reciprocating Rig (HFRR) apparatus was employed in order to evaluate the tribological properties of the oxidized samples in accordance with CEC F-06-A standard method. The influence of commercially available antioxidant agents on the lubricating efficiency of biodiesel blends was examined. BHT (butylated hydroxytoluene) and TBHQ (tert-butylhydroquinone) were separately added to the above mentioned FAMEs and a comparative assessment of the tribological properties of the relative biodiesel blends was performed by repeating the oxidation procedure and lubricity measurements.	en
