“…In many tribological experiments to assess the thickness of the oil film, electrical methods, in particular resistance ones, are used [75]. However, the authors' research and the literature on triboelectric phenomena show that this is a wrong approach.…”

This article concerns the method of material consumption assessment of the cylinder-piston group of diesel engines in the biodiesel environment. The obtained experimental dependences of the wear coefficients on the example of the tribounit cylinder liner and the piston ring can be used to forecast the resource use during operation under specific conditions of the engine and the environment as a whole. The article systematizes the types of biofuels, depending on the type of raw materials from which they were made, taking into account the process and application. The physical and chemical aspects of the catalysts used for biofuels were indicated. The applied experimental methods for tribological wear of the piston-cylinder pair were analyzed. B70 biodiesel was used in the research, i.e., 70% mineral diesel oil and 30% methyl esters of rapeseed oil. Experimental tribotechnical studies of the influence of biofuels on the behavior of various materials have shown that when using this type of fuel, it is necessary to replace the materials from which some parts of the cylinder-piston group are made. To solve this problem, research has been carried out on a specially designed friction machine. The novelty in the article concerns the association, based on the literature, of hydrogen consumption causing material wear in friction contacts. The mechanism of the interaction of various construction materials during such friction has been disclosed.

“…Besides the indexes, in tribological research is observed also electrons and charged particles emission, what is described in many articles [1][2][3][4][5][6][7][10][11][12][13][14][15][16][17] as the triboelectric phenomenon. This phenomenon has significant influence on forming and destroying of boundary layer [6,11,13,15,16]. It means that an energy emited in kinetic pair (heat, electricity) can form but also devastate boundary films, what is depend on individual properties of the layers.…”

The subject of this paper is assessment of friction process of model kinetic pair worked under DC voltage. The friction under this conditions may take place in case of triboelectrical phenomena and in friction pairs of electrical motors. The significant influence of electric current flow on friction resistance and boundary film thickness was presented. Results of the research were compared to the results of research under load and without electric current applied.

This paper presents and discusses an experimental method of friction during the current flow in sliding zone with lubrication. There is also showed typical friction changes of several parameters depending on a load and DC voltage. It allows to observe positive and negative results of the friction. A low level of electrical energy used in friction zone can improve the work conditions. When power of the electric energy is exceeded it leads to the micro-welding, especially during the high load. On the other hand we notice a new possibility of using electric current to friction force steering.
