The article discusses the possibilities of detecting defects in the marine diesel engine injection system on a selected example. Basing on statistical data, it was pointed out that these engines had a significant failure rate in relation to the failure rate of other machinery and equipment used on ships. First, it concerns damage of the elements of the injection systems. Therefore, basing on the results of the authors’ own research, the possibility of improving diagnostic methods of the injection system that can be used in the ship operation process was pointed out. First, high diagnostic effectiveness of the analysis of pressure changes measured in the injection system was pointed out here. At the same time, taking into account the difficulties of such measurement in the conditions of the ship’s power plant, it has been shown that very good diagnostic effects can be obtained by using indicator diagrams to calculate heat release characteristics. On the selected damage of the injection pump example, the diagnostic usefulness of net heat release (Q) and intensity of heat release (q) has been shown. The improvement of diagnostic methods allows increasing the efficiency of diagnosis of marine engines.
