СИСТЕМЫ МОНИТОРИНГА СУДОВЫХ ДИЗЕЛЕЙ В ЭКСПЛУАТАЦИИ

Abstract

The article provides an overview of currently used diagnostic systems of medium- and high-speed marine diesel engines. The parameters controlled by diagnostic systems have been discussed. The advantages and disadvantages of the monitoring systems of marine diesel engines designed as a single software-hardware complex have been analyzed. As it has been stated, universal monitoring systems for engines of different models are not created. Specialized diagnostic systems are only installed in powerful engines which are used on sea-going ships, not on river vessels and mixed (river-sea) navigation vessels; such complexes have not been applied so far. According to the results of the analysis, there have been listed engine diagnostic parameters required for implementing algorithms of automatic diagnostics without disassembling. The paper presents a review of commercially available sensors for measuring parameters of engines in operation. It has been shown that currently the decision of tasks of technical diagnostics of marine engines and, therefore, other less complex mechanisms of a ship power plant on the river vessels is possible because of modern electronic control systems that allow continuous monitoring of technical parameters, i.e. collecting and processing information received from sensors of the controlled variables and processes.
