“…Since during the circulation of the working fluid in the hydraulic system, it is prone to loss of its quality properties, the features of changing which are described in the textbook (Boichenko et al, 2019), which lead to ageing of the working fluid and indicate a stochastic relationship between pressure and kinematic viscosity for further development of a method for predicting the state of the hydraulic drive.…”

The paper presents the results of research on tribological parameters of friction pairs at lubrication with hydraulic fluid and mineral oil. Friction pairs BrPh6,5-0,15 and Hardcarb-TP with steel 40Х at lubrication with hydraulic fluid AMg-10 and mineral oil I20A have good tribological properties. At load 2,003 MPa, temperature 20 °C and speed 2,5 m/s the coefficient of friction does not exceed the value 0,1. It is not recommended to use hydraulic fluid AMg-10 at contact pressure 3500...5500 MPa, because the coefficient of friction is higher than 0.65. Industrial oil I20A provides low coefficient of friction 0.1-0.2 at these contact pressures.

The article considers the problem of using waste as an energy resource. The possibility of processing liquid carbon-containing waste, which is formed during the processing of agricultural products, the use of fats in the food industry and oils in transport, is analyzed. An analysis of the volumes of such waste is presented. It is shown that sunflower processing is accompanied by the formation of about 7,000 tons/year of liquid carbon-containing waste. Technological processes of food industry generate about 1,000 tons of such waste per year. A significant source of waste generation is motor vehicle companies, the total resource of which for the introduction of competitive processing technology is currently about 100,000 tons of olives. A promising resource source for the proposed technology is the process of thermal destruction of used automobile tires, of which 250–300 thousand tons are generated annually in Ukraine. Possibilities of introducing the technology of thermal decomposition of liquid carbon-containing substances of various origins, as components of waste, to create gaseous products of a given composition with further use in the chemical industry and replacement of natural gas are considered. The thermal decomposition of hydrocarbons with stabilization of the process due to the introduction of a high-temperature plasma discharge source into it is among the most promising methods of performing such a task. The results of the development of the methodology for the analytical study of the composition of gaseous fuels are presented. The concept and schematic diagram of the experimental stand are presented. The results of test studies are presented. Bibl. 15, Fig. 5, Tabl. 5.
