The study of the reliability of the engine as a whole can be represented as a study of the

probabilistic characteristics of its reliability according to the given probabilistic characteristics of the

reliability of individual engine elements, that is, systems and mechanisms.

The article substantiates that the method of similarity and dimensional theory allows us to establish

patterns of change in the wear rate tgα depending on the adjustment of the engine parameters, and

numerous experiments are required, which makes it little practical in determining the resource and

predicting the operation of tractor engines.

A more practically acceptable method for determining the residual life of automotive engines is the

method of mathematical statistics and probability theory, and, in particular, the law of normal

distribution. However, to determine the resource of engines, using this law, it is also necessary to conduct

a large amount of testing.

Thus, at the current stage of scientific and technological progress in automotive engineering, it is

necessary to find other methods that are most practically acceptable and contribute in a short time,

without a large amount of testing, to determine the resource of machines with maximum durability, which

will be developed in subsequent works of the authors of the article.
