Opis:: In this work has been undertaken a study test the application course of combustion pressure signals in combustion chamber the marine medium-speed engine to diagnostic. In research has been used active experiment. The pressure signals analysis in cylinder has been carried out in amplitude and frequency domain, as new method for result processing. In preliminary research has been carried out with used marine engine 5BAH22 with current generator, be present in Engines Room Laboratory the Maritime Academy in Szczecin. Preliminary research has consisted in measurement the course of combustion pressure signals in individual cylinders and analysis the combustion pressure signals in time, amplitude and frequency domain at different engine load the combustion engine and has been checked that diagnostic parameters will be correlate with engine load. The current generator has been loaded with water resistor. The purpose of this work have been selected sensitive diagnostic symptoms and checked their usability in diagnosis marine diesel engine. In principal research has been simulated inability the turbocharger air filter as his mechanical impurities. Useful diagnostic symptoms have been determined. The method were being verified, execute operating research on working marine diesel engines at port and shipyard.

Opis:: The paper presents the effect of the main parameters of pilot dose ignition: injection pressure, injection advance angle and injector opening time on the combustion process in a dual fuel diesel engine. The study continues the research conducted at the Department of Mechatronics of the University of Warmia and Mazury, Olsztyn, on optimisation of dual fuel self-ignition engines with CNG as the main fuel dose. The results presented in the paper were obtained with a single-cylinder engine HATZ 1B40, adapted to methane combustion. The results presented in the paper show the recorded changes of pressure in the combustion chamber with a constant fuel pilot dose and different ignition advance angles. Scheme of fuelling and measurement systems, view of engine indicating system, average changes of pressure in the combustion chamber, average changes of pressure in the combustion chamber and average changes of pressure in the combustion chamber at dual fuel engine supply with diesel oil at varied pilot dose injection angle, effects of advance angle of the pilot dose injection on the maximum pressure of combustion, at various proportions of diesel oil and CNG, average changes of pressure in the combustion chamber at double-fuel engine fuelled with diesel oil and various shares of methane in the dose powering the engine, CNG consumption as a function of the advance angle of the pilot dose injection for various shares of the pilot dose are presented in the paper.

Opis:: Natural gas is one of the potential combustion engine fuels whose proportion in the overall energy balance is expected to increase. Owing to some of its properties, its use requires a dual-fuel supply system; thus, the use of natural gas as a fuel for diesel engines is currently limited. Systems that supply gas fuel to diesel engines do not usually interfere with the engine control system. This solution significantly reduces system-installation costs. However, as demonstrated in the present study, it considerably changes the course of the combustion process, which increases thermal and mechanical loads. In this case, the combustion process can be controlled by changing the liquid fuel injection pressure or advancing the injection angle. This, however, requires interference with the engine control system.

Opis:: W artykule przedstawiono wyniki zastosowania analizy przebiegu ciśnienia w cylindrach okrętowych średnioobrotowych silników tłokowych w dziedzinie czasu, amplitudy, częstotliwości oraz analizy falkowej do ich diagnozowania w celu wyboru racjonalnej metody. Przeprowadzono wstępne i zasadnicze badania eksperymentalne z wykorzystaniem metod planowania eksperymentu. Wstępne badania zostały przeprowadzone na okrętowych silnikach Sulzer napędu prądnic, występujących w siłowniach masowców i polegały na pomiarze sygnałów ciśnienia w poszczególnych cylindrach i analizie ich przy różnych obciążeniach silnika oraz sprawdzaniu ich korelacji z obciążeniem. W badaniach zasadniczych oceniano stan techniczny poszczególnych cylindrów przy stałym obciążeniu. Przydatne symptomy diagnostyczne zostały wyselekcjonowane, a metodę zweryfikowano lokalizując uszkodzenia elementów silnika.
In this work has been presented the results of the the application in-cylinder pressure signal analysis of the marine medium-speed engine to diagnostics. In-cylinder pressure signals analysis has been carried out in amplitude, time and frequency domain as well wavelet analysis for their diagnostics to select a rational method. There have been carried out preliminary and principal investigations using experiment planning. The preliminary research have been done on marine diesel engines Sulzer type drive generators, occurring in engine rooms of bulk carriers and rely on the measurement of pressure signals in each cylinder and analyzing them under different engine loads and verify their correlation with the load. In principal research has been diagnosis technical state of individual cylinders at constant loading. Useful diagnostic symptoms have been selected. The method was being verified locating failures of engine elements.
