Initial research of the effect of fame containing petroleum fuel blends storage on lubricity

This paper describes the effect of fatty acid methyl esters (FAME) content in aviation fuels and diesel fuels on lubricity of such fuel blends. Standard petroleum fuels being currently in use contain various components, including the very important ones such as FAME and biohydrocarbons. The latter ones have been used also in aviation turbine fuels. Such use is, among others, associated with limiting of harmful combustion products emission. Lubricity, as one of important parameters related to fuel, directly effects on drive units use. Insufficient fuel lubricity effects probably on extended wear or injection system failure resulting in deterioration of combustion process, emission increase, and engine itself failure. Lubricity study included in this paper was carried out basing on standard test methods with HFRR and BOCLE. The paper describes the nature of lubricity change in relation to prepared fuel blends depending on FAME volume content, as well as the initial storage effect on test results.
