One of the functions of engine fuels is the lubrication of engine injection equipment components. The elements
of the injection system are lubricated only with the fuel used to power the engine; therefore, the lubricity and
its impact on the elements of the engine injection system are an important issue. The share of biofuels to
power internal combustion engines is constantly increasing, because EU Member States are required to use
fuel with the addition of biocomponents to power vehicle engines. These fuels are more ecological compared
to petroleum fuels. Therefore, it is also necessary to identify the lubricating properties of these fuels, which
can significantly affect wear processes.
In order to identify wear indicators, laboratory tests were carried out to determine the lubricating properties of
biofuels based on vegetable oils in relation to diesel fuel. Tribological tests were carried out for the ball-disc
friction node of 100Cr6 material, which is most often used in the construction of precision pairs of injection
equipment. Comparative tests were carried out for samples immersed in a fuel bath on a CSM tribometer.
The friction coefficient waveforms as a function of friction distance and sample load were determined.
The measured force values indicate a significant impact of the fuel used on the operating conditions and
consumption in the kinematic pair being the subject of the work.
