Engine technologies whose application can reduce the impact of friction are surface coatings and the lubricants low-viscosity or with appropriate additives. As a contribution, we applied the eco-tribological knowledge during construction of IC engines and their spare parts. The result of the researches was patented prototype of the aluminum piston coated or modified with tribo-material in area of skirt. Modification of the piston was realized by inserting two removable pads (plates) of graphite. Another option is the piston with tribological pads of steel into which are inserted tribo inserts of graphite in the form of a sphere (nodules). The main task of the tribo-pads is to decrease friction between piston and cylinder, especially at engine-starting regime. This is confirmed during researches whose the results are presented inside of manuscript.
