With a variety and dispersion of factors that determine the durability and wear resistance of the internal combustion tribome, the change in wear and wear intensity during the operation has a pronounced natural character. Evaluation of the design and manufacture of ICE is based on a comparison of the indices of durability and wear resistance of the actual and theoretical tribo-conjugation. Manufacturing tolerances reflect the potential of technical production capabilities. The design coefficient shows the correspondence of the geometry of the newly manufactured friction surface to its optimal, attained parameters. The experimental data are taken from the results of road and accelerated tests of the engines GAZ and ZMZ. Reducing wear in the run-in, design and manufacturing errors is due to improved design and lower manufacturing tolerances. Reducing the intensity of wear and increasing the operating time of parts is associated with the improvement of the material of rubbing surfaces and lubricant, and improvement of roads. The change in the design coefficient indicates that there are no pronounced trends in the design and production of the geometric parameters of the tribo-conjugate. Domestic automotive industry and engine building focused mainly on the domestic market. Design and production took into account the high demand for machines, the sparseness of the larger territory of the country, i.e. low concentration of machines in these areas and the difficulty of organizing a company service that is dependent on the number of machines in the service area. As a result, many vehicles have become uncompetitive in terms of technical characteristics, in price and reliability. The course for the modernization of the production of engines presents increased requirements for design, consisting in the full use of the technical capabilities of manufacturing and determining the prospects for their further growth.designproductioninternal combustion enginesdurabilitywear resistanceпроектированиепроизводстводвигатели внутреннего сгораниядолговечностьизносостойкость[Гурвич И.Б.
