Abstrakt

One of the main difficulties associated with the use of FAME biofuel (fatty acid methyl esters) in its pure form as an engine fuel is its destructive effect on fuel system components made with traditional materials. This applies to both elements made out of metal (corrosive effect), as well as synthetic materials. This study attempts to assess the impact of FAME biofuel on sealing elements of fuel filters, which are made of fluorine rubber and nitrile butadiene rubber. The results showed that the mechanical properties of fluorine rubber do not change in the conditions of prolonged contact with FAME. Thus, it can be safely used in fuel systems for engines fuelled with FAME as a neat fuel.
