Digital diagnostics of internal combustion engines in the agro-industrial complex engineering service

The trends in the development of technical diagnostics in the agroindustrial engineering service are presented, and the most promising areas of its development based on computer and information technologies are presented. The expansion of the range of devices and equipment for obtaining objective information about the operational reliability of internal combustion engines of energy-saturated equipment allows for comprehensive research in this promising area. The results and analysis of this work consist in an integrated approach to conducting research in terms of developing digital diagnostic methods, assessing the level of maintenance using this diagnostic method, and analyzing ways to respond to the output signals of malfunctions of internal combustion engine elements of energy-saturated equipment. It has been established that the introduction of digital diagnostics of internal combustion engines makes it possible to reduce the operating costs of agricultural producers by 12–15 % due to the resource actually used, to ensure a reduction in the number of repairs and a reduction in the volume of purchased spare parts.
