Annotation

The reliability of automotive internal combustion engines is a function of the reliability of their mechanisms and systems. For many years, domestic and foreign engineers have tested many auto-tractor internal combustion engines and it has been proven that if mathematical models reliably describe physical phenomena, cycles or processes that take place in engines, then the theory of small deviations for theoretical research is much better than any experiment on control characteristics and many second parameters
The theory of small deviations for fuel equipment of autotractor diesel engines is considered in the article. The method of transition from the ordinary differential equations describing the quality of diesel fuel spraying to the equations in small deviations. Equation of kinematics and hydrodynamics of precision pairs of fuel equipment in small deviations. Consumption characteristics of fuel in the process of injection in small deviations. Methods of similarity, dimension theory, mathematical statistics, and probability theory, which are used in determining the resource and predicting the operation of tractor engines. It is shown that the most practically accepted method for determining the residual life of autotractor engines is the method of mathematical statistics and probability theory. The role of mathematical modeling in determining the residual life of fuel equipment of autotractor diesel engines is established. It is also noted that it is advisable to use the small deviation method to accurately describe the processes in the fuel equipment of autotractor diesel engines.
The mathematical model is based on the known physical laws that describe the interdependencies of the two groups of parameters, control and operational, both within and between groups. The transition of the classical differential equations describing the processes of fuel supply and injection, taking into account fuel leaks in precision pairs, into equations with small deviations of parameters, is shown. The relationship between injection, fuel supply and fuel leakage is analyzed and the most influential parameters found. Impact coefficients are found and their dependencies are plotted on their corresponding parameters. Using the obtained dependencies, the influence of the technical condition of precision pairs on the effective performance of the engine is characterized. Dependences of change of injection characteristics on small deviations of parameters characterizing the technical condition of precision pairs of fuel equipment are also established.

Keywords: fuel equipment, diesel engine, small deviation method, mathematical modeling.
