The article considers utilization of organic waste from poultry farming being an urgent problem of agriculture. Leaders of large poultry farms are interested in using low-cost recycling schemes aimed to process waste into safe products in a short time. This paper considers the possibility of using an organic fertilizer “Soil Improver (UP-1)” obtained by processing poultry waste by using a biologically active additive Mefosfon, which is a melamine salt of bis (oxymethyl) phosphinic acid. Field tests were carried out in 2019-2020 on the lands of OAO “Agrofirma “Ak Bars-Pestretsy” being the branch of the Poultry farm of the Pestrechinsky district of the Republic of Tatarstan. The object of the study was the recognized variety of soft winter wheat “Scepter” ES (elite variety). The rate of application of chicken compost and organic product UP-1 in the control and experimental plots was 56 tons per 1 ha. The experimental data show that wheat cultivated with the application of UP-1 compost was distinguished by higher rates of field germination (increased by 13 %); the length of secondary roots was 11.2 % greater compared to control. The grain produced in this variant had higher hardness (control – 62 %, UP-1 – 72 %) and the quality of crud gluten (74.0, 78.0 %, respectively), the yield of winter wheat grain – by 0.06–0.12 t/ha (1.2–2.5 %), which indicates the feasibility of using fertilizer from poultry manure in crops cultivation.

When assessing the cause of torsional vibrations on the crankshaft of tractor engines, forced vibrations are taken into account, which are provoked by torques arising from each cylinder and transmitted to the connecting rod necks, taking into account the order of operation of the cylinders. Researchers have only calculated or experimental values of the torque for different angular positions of the crankshaft with a certain sampling step. The algorithm for solving the torsional vibration problem involves the decomposition of discrete values of the torque of one cylinder into a harmonic series in order to determine its amplitudes and phase shifts. The adequacy of the resulting decomposition is determined by the number of harmonics taken into account and, as a rule, includes 10-12 harmonics. At the same time, it is necessary to perform such decompositions for each speed and load mode, which increases the amount of calculations. An algorithm is proposed that considers these modes separately, and depending on the values of the gas and inertial forces, allows using the characteristics of the nominal operating mode and the decomposition with a smaller number of terms. In this case, the results of the expansions have a satisfactory convergence. The proposed method for determining the parameters of motor harmonics of exciting moments under changing speed and load modes of the internal combustion engine, can be useful in the design of new and fine-tuning dampers of torsional vibrations of crankshafts.

“…It is also possible to use a method of tuning the intake channels in resonance, which is devoid of this inconvenience and allows to achieve resonance without changing the length of the manifold: the initial length is chosen with the condition of resonance for one speed mode of the engine, and further tuning of the system occurs by installing one or two resonators in the intake tract. For this purpose, resonators of variable volume are connected to several (often one or two) points of the intake pipe [7,8].…”

Increasing the effective performance of automotive tractor engines is primarily associated with the intensification of the working process parameters. One of the options for solving this problem is to improve the cylinder filling parameters, which will allow to increase the engine power and torque. In addition to mechanical and gas turbine supercharging, the little-studied resonant supercharging of the engine is of interest. In this case, by selecting the parameters of the inlet path of the engine, it is possible to achieve a significant increase in pressure in the zone of the inlet valve opening without expenditure of useful energy, using only the kinetic energy of the gases of the inlet path. The paper proposes a method to calculate the geometric parameters of the intake tract using a one-dimensional model of gas flow. The results obtained from the numerical investigations give good convergence. The article can be useful for masters, graduate students, and engineering and technical workers involved in the design of internal combustion engines.
