Abstract

A large number of engine development specialists from leading foreign companies are focusing their efforts on increasing efficiency, using various technological capabilities to improve internal combustion engines.

The article deals with the issues of studying the theoretical prerequisites for the development of a military internal combustion engine with its additional loading during the formation of a working mixture divided into two axes, with a kinematic decoupling proposed between the valves of the combustion chambers.

The purpose of the theoretical study is to improve the technological scheme of an internal combustion engine with a valve mechanism built into the design of the cylinder-piston group.

The scientific and practical significance of the work is that for the first time a technology has been applied where the combustion chamber consists of two separate chambers, which, when the crankshaft rotates and the piston moves, are composed in frequency and amplitude, while the law of energy storage is applied, which allows a detailed approach to the consideration of the implementation of torque on the wheeled propulsion of a military vehicle.

The methodology of the study is the mathematical determination of the value of the efficiency, which is formed when the combustion chamber valves are switched with the amplitude and frequency of their switching when they move along the inner surface of the piston, which makes it possible to increase the dynamics of the vehicle.

The result of the study is a proposal to improve the design of the internal combustion engine (ICE) of a military truck, in which, structurally, during the formation of a working mixture divided into two masses, the combustion chamber structure was separated by separating the combustion chamber structure and the kinematic solution of the separated chambers was performed. During the rotation of the crankshaft and the movement of the piston with an internally built-in valve mechanism, the mixture movement in difficult working conditions and its simultaneous turbulent rotation on the inner surface of the combustion chambers was improved, which allows to promote the emergence of additional speed of the mixture and its torque, as well as the creation of self-ignition cells and increase the dynamic capabilities of the engine as a whole.

Keywords: amplitude, frequency, two-axle (separate) structure, wheeled propulsion system, combustion chamber, valve, motion dynamics, military vehicle.
