“…On the other hand, the search for the corresponding mathematical dependencies is also very difficult in terms of calculation, if only because both the length and diameter of pipelines in the case of inertial resonance supercharging almost directly affect the supercharging process itself [10,11].…”

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.

Increasing the efficiency of modern internal combustion engines is going in the direction of optimizing the gas distribution phases in order to adjust them to the operating conditions of motor vehicles. Hyundai has announced the development of the first production engine with continuously variable valve operation time – Continuously Variable Valve Duration. (Research purpose) The research purpose is in conducting a kinematic analysis of the gas distribution mechanism with an adjustable valve operating time, identifying the theoretical possibilities of this mechanism in comparison with the information provided in the prospects. (Materials and methods) The methods of kinematic analysis of lever mechanisms were used in the work. (Results and discussion) The analysis of the design of the gas distribution mechanism with an adjustable valve operating time made it possible to choose a suitable structural scheme that is equivalent to the original mechanism. The article presents the most effective method of kinematic analysis of this mechanism and developed on its basis a program for calculating the angles of rotation of the cam and the shaft of the gas distribution mechanism. (Conclusions) An engine with a valve operating time control system allows you to more effectively adjust the cylinder filling depending on the operating conditions due to the variable phase of rotation of the camshaft. The valve timing control system offered by Hyundai should only work with the valve timing control mechanism, since when the cam rotation speed changes, it starts working in the wrong phase that should be at a given time. With a slow rotation of the cam, it lags behind in phase from the shaft of the gas distribution mechanism, and with a fast rotation of the cam, on the contrary, the phase advance of the shaft of the gas distribution mechanism occurs.
