“…Usually, the cetane numbers are derived for fuels related to compression engines rather than turbine engines. However, blends of alternative jet fuels with conventional jet fuel are also studied [48][49]. Derived cetane numbers (DCN) of 60 have been recently reported for most of the alternative fuels tested, with the reported DCN for Jet A of 49.35 much lower [48].…”

“…Previous studies regarding the lubricating properties of diesel fuel and ethanol mixtures have focused on comparing the WSD (wear scar diameter) parameter, determined based on tests carried out following the HFRR method [ 47 , 48 ]. For example, Kuszewski et al [ 32 ] observed no significant differences in the value of the WSD parameter for diesel fuel and ethanol blends at different ethanol volumes.…”

“…As a result, the obtained results did not align with observations during engine tests concerning the wear of injection equipment elements with ethanol fueling [ 49 ]. Other studies, particularly [ 48 , 50 ], have shown that the HFFR method for low fuel additive concentrations is characterized by low sensitivity to lubricity results. Under such conditions, some polar compounds, due to their low concentrations, may not produce a sufficient lubrication film, which can lead to degradation in the tribological node [ 51 ].…”
