Abstract

In this paper, in terms of diagnostic tests, functional systems composed of a technical object that is marine diesel engine piston were presented. This decomposition enables the identification of diagnostic systems, where failures occur most frequently and those whose failure may cause serious This decomposition enables the identification of diagnostic systems, where failures occur most frequently and those whose failure may cause serious consequences further consequences. Marine diesel engine was divided into the following functional systems: piston-crank exchange of the working medium, fuel supply, lubrication, cooling, starting, starting and reversing. Operating practice showsthat the most common marine engine failure include damage to the injection system, the injectors, injection pumps, fuel system, speed controllers, lubrication system, timing mechanism, as well as the cooling system malfunctions. In this paper, examples of currently used diagnostic systems were described. In addition, the unconventional methods of diagnosing piston engines were presented.These are new, increasingly completely without disassembly and without any interference in the process of the internal combustion engine technical condition testing methods. Measurement systems computerization causes they are used with the simultaneous use of artificial intelligence and especially expert systems. These include, inter alia, vibration analysis, marine engine exhaust gas analysis, acoustic emission, endoscopy and quick photography in research diagnostics. Then infirmities cooling system were presented. The problem of development of methods of diagnosis and diagnostic system for marine diesel engine cooling system was formulated. It has been found that the developed diagnostic system would be a good complement to the existing electronic surveillance systems of the marine engine technical state.
