The relevance of the problem under study is due to the need to substantiate the sufficient number of tractors used for various technological operations, depending on the volume of works performed, and taking into account their influence on the crop yield. The purpose is to develop the mathematical model of machine and tractor units used in technological operations by formalizing the vague concept of optimal agrotechnical timing of technological operations and calculating the optimal number of tractors to perform works by the total energy costs. The main research method is mathematical modeling of operations performed by machine-tractor units based on the system analysis and computational experiments and using the energy mathematical model. The article describes a criterion for optimizing the tractor parameters, dependences of the energy mathematical model of the unit. The results of computational experiments showed that for each operation there is an optimal number of tractors and tractor units minimizing the minimum total energy costs. Calculations were carried out when treating 1000 hectares with various tractors. It was revealed that the total energy consumption differs by 2 or more times. The required number of tractors depends on their main parameters, propeller parameters and other factors. It was revealed that with an increase in the volume of works, the required optimal number of tractors increases. The method for substantiating the required optimal number of tractors in technological operations will improve operations of tractors used by large agricultural producers, reduce the total energy costs for cultivating up to 12–16 thousand MJ/ha.

Internal combustion engines are equipped with turbochargers to increase their power, while the design of the engine itself practically remains unchanged. The turbocharger operates at high rotor speeds (25000 ...110000 min -1 ), as well as at high temperature conditions (650...700 ºC). The problem is compound by the fact that the bearing assembly receives a lubricant that was involved in lubrication of the rubbing elements of the entire engine, since the turbocharger bearing lubrication system is combined with the engine lubrication system. This leads to increased wear on the turbocharger bearing and a reduction in its service life. These circumstances require an increase in the lubrication efficiency of the turbocharger-bearing unit. To solve this problem, we have developed a new design of an individual lubrication system for the internal combustion engine turbocharger bearing. The design solution allows to provide the turbocharger bearing assembly with lubricant in the engine start mode and after it stops during the rotation of the rotor by inertia for 90 seconds. The article deals with the design calculation of the individual turbocharger bearing lubrication system. In order to be able to calculate the design of an individual turbocharger bearing lubrication system for any engine, a mathematical model has been developed. The final formulas for calculating the parameters of the turbocharger bearing lubrication system are present, as well as specific calculation results for the most common brand of turbocharger.

“…The nature of the processes occurring in the soil under the influence of the working body depends on its geometric parameters, operating modes and physical and mechanical properties of the soil. The shape of the working body mainly determines the quality of tillage and its energy consumption [1][2][3][4][5][6]. Academician V.P.…”

The article presents the results of experimental research of a conical rotary loosener for deep soil tillage. The loosener is a screw rotary conical tool mounted on a rack, with the possibility of rotation around its own axis from the reaction of the soil. Experimental research to assess the traction resistance of the loosener and to determine the dependency of the number of its revolutions per 1 meter of the traveled distance on the design parameters and the speed of movement were carried out in the soil canal of the Kazan State Agrarian University in accordance with the developed methodology. The influence of the number of turns of the loosener n, the rear cutting angle ε, the speed of movement υ and the hardness of the soil H on the traction resistance and the number of revolutions per 1 meter of the traveled distance of the loosener were studied. The soil in the soil canal was gray forest soil with a medium loamy texture. The values of soil density at the level of 1500 kg•m -3 with its moisture content of 17-18%, and the hardness varied in the range of 1.8-2.35 MPa. As a result of the calculations, regression equations were obtained for the traction resistance of the loosener and for the number of revolutions per meter of distance traveled. They were tested for adequacy according to the F-Fisher criterion. As a result of the research, the rational value of the number of turns n = 0.33 was established, the rear cutting angle of the loosener ε = 4-5º, the travel speed υ = 2.5 m•s -1 .
