DIAGNOSTICS OF INTERNAL COMBUSTION ENGINES, STATE AND PROSPECTS IN THE ENGINEERING SERVICE OF THE AGRO-INDUSTRIAL COMPLEX

Abstract

The paper presents the trends in the development of technical diagnostics in the engineering service of the agro-industrial complex, the most promising areas of its development. (Research purpose) The research purpose is analyzing the state of modern technical diagnostics in the engineering service of the agro-industrial complex, considering the development of new methods and technical diagnostic tools based on computer and information technologies. (Materials and methods) Modern information technologies, automated control and management systems were used during the research. The expansion of the range of devices and equipment to collect and proceed the information about the operational reliability of internal combustion engines of high-energy agricultural machinery allows for comprehensive research in the technical diagnostic. (Results and discussion) Authors used the integrated approach when conducting research in terms of developing methods of contactless diagnostics, assessing the level of maintenance using this diagnostic method, analyzing methods of contactless diagnostics that allow us to respond to the output signals of malfunctions of internal combustion engine components. Contactless diagnostics of internal combustion engines can reduce the number of failures by 1.5 or more times, increase the repair service life by 1.2-1.5 times, reduce maintenance costs by 15-20 percent, reduce fuel consumption by 12-15 percent and increase the durability of parts by 10-12 percent. (Conclusions) The research forms the scientific basis for the effective use of contactless diagnostics. The introduction of this method of technical diagnostics of internal combustion engines makes it possible to reduce the operating costs of agricultural producers by 12-15 percent due to the economical using of resources, to ensure a reduction in the number of repairs and a reduction in the number of spare parts purchased.
