“…The purpose of force analysis of the damping attachment is to obtain analytical expressions for determining the numerical values of the magnitude of the acting forces at any moment in different points of the mechanism and their transfer to the tractor [19][20][21]. The forces in the joints of the mechanism links will be determined by the components in the horizontal and vertical planes.…”

Efficient use of agricultural tractors is largely determined by the operating modes of its power units. Taking into account the variable nature of external loads, it is necessary to provide structural devices in the tractor, which smooth out changes in hook load, thus reducing the negative impact of external conditions on the operation of its power plant. The present paper is devoted to the design of a tractor attachment with variable characteristics. The methods of studying the variable traction force are analyzed on the output parameters of the technological process, as well as on the power and economic indicators of the power unit. Force analysis of the proposed attachment device is carried out and formulas are obtained to determine the forces and moments at the characteristic points of the device. The paper is of interest to engineers and technicians involved in the creation of promising design schemes for tractor tractors of various operational purposes.

“…This engine uses a microcomputer to control the engine load state, automatically adjust the idle speed device and the exhaust gas recirculation device to make the engine work smoothly, thereby reducing fuel consumption and exhaust gas emission. In 1902, Mr. Robert Bosch invented the world's first spark plug with a high-voltage electromagnetic ignition system [3]. In 1922, he invented the mechanical injection device.…”

Since the internal combustion engine came out in the 1960s, it has become a relatively perfect machine through continuous improvement and development. Internal combustion engine has many advantages, such as thermal efficiency, high power, wide speed range, convenient matching and good mobility, so it has been widely used. All kinds of automobiles and tractors, agricultural machinery, engineering machinery and small mobile power stations in the world are powered by internal combustion engines. Ships, conventional submarines and some small aircraft are also propelled by internal combustion engines. The number of internal combustion engines in the world ranks first in the power machinery and plays a very important role in human activities. In the aspect of human technology, any successful invention can not be achieved overnight. The development of the internal combustion engine is the same. The internal combustion engine has gone through many stages of development and has been improved one after another. This paper mainly introduces the historical development of heat engines, and the improvement and use of different types of heat engines in the development.

An accurate choice of the design model of the crank-connecting rod mechanism of piston internal combustion engines affects the accuracy of the calculation results and their complexity. At present, most of scientists and technicians choose a two-mass design model to analyze the operation of the crankconnecting rod mechanism. The model considers only the rotational and reciprocating movements of two masses, which are connected by a rigid weightless rod. This model significantly simplifies the calculations, neglects the elastic deformations of the parts of the crank-connecting rod mechanism, and eliminates the need for compiling the equations of dynamics in partial derivatives. However, the model has a number of drawbacks. The calculation results obtained using the two-mass model exhibit significant errors, which mainly depend on the design features of the connecting rod assembly. The paper discusses multi-mass design models, where the connecting rod assembly can comprise several lumped masses located along its length. In this case, the plane-parallel motion of these masses is added. The masses have weightless and absolutely rigid bonds. Forces and moments acting on the piston assembly and the crank are calculated according to the equations compiled. Comparison of the calculation results with the results obtained for a two-mass model can be used to determine errors and choose a design model that provides the required accuracy. The considered design model is of interest to engineers and technicians engaged in the design and calculation of the crank-connecting rod mechanism of piston internal combustion engines.
