Purpose: The aim of this paper is to present differences of friction process occurred in research carried out on tribological apparatus with diesel fuel and biocomponent additives. The analysis of coefficient of friction and electrical resistance of kinematic pair took place. It was done for kinematic pair worked in pure diesel fuel and biofuel as a diesel fuel with fatty acid methyl ester (FAME) additives. Design/methodology/approach: The research were conducted on HFRR apparatus (dedicated for lubricity assessment of diesel fuel) and tribotester TR-2. The research were carried out with pure diesel fuel and diesel fuel with 5% and 10% (v/v) content of FAME. Findings: The results of the research indicate that on account of different construction of apparatus, the friction process assess on the basis of coefficient of friction and resistance is not identical. The FAME additive causes increase of resistance that is over the measuring range of HFRR apparatus. The fact leads to conclusion that standard assessment of lubricity should be replenish by additional analysis of coefficient of friction and kinematic pair resistance. Research limitations/implications: The research was conducted only for diesel fuel and mixtures of the fuel and FAME. Other fuels were not taken into account. Practical implications: The presented results can be used as a value directions in research development of fuels and biofuels properties. Originality/value: The standard research of fuel lubricity boils down to determine wear diameter. This paper indicates other, non-standard approach by additional parameters analysis as coefficient of friction and kinematic pair resistance that was done on tribometer TR-2.
