Opis:: The paper presents results of the experiment focused on evaluation of records of runs of the engine in good condition as a reference for subsequent detection of faults of fuel system of medium speed diesel engine. The aim of research was determination of limits of instantaneous angular speed's spread spotted between random starts of the engine, without any fault condition simulation. Due to fine variation of the load setup and different ambient condition, every record of angular speed of independent starting, despite of attempts to sustain the same load and rotational speed value, presents some deviations between runs. Having on mind utilization of such measurement as a template for further comparison, is crucial to find out how random changes of ambient conditions and accuracy of revolutionary speed setup affect the IAS magnitude course. The answer was got in way of registration of numerous runs of the test engine after independent starts and hand adjustment of required RPM’s. The experiment was carried out at laboratory stand in GdyniaMaritimeUniversity, equipped with diesel engine Sulzer 3AL 25/30 driving electrogenerator. Sulzer 3AL 25/30 is three cylinder, medium speed, four stroke marine diesel engine, with maximum output 400 kW at 750 rpm. Independent records were treated as random variable and were compared each other. Obtained results were compared with differences between healthy engine and with simulated malfunctions of fuel injection.

Opis:: It is assumed that elements of Exhaust Gases Cleaning Systems creates additional resistance along fumes duct and can affect energetic process of combustion. In the paper are presented results of researches aimed on detection and recognition of dumping effect in the exhaust pipeline using devices dedicated for engine’s torque and angular speed measurement. The experiment was carried out in test stand of Gdynia Maritime University; equipped with one-cylinder, low speed engine working in two-stroke mode. Effect of increasing of gas flow resistance was achieved by installation of shutters in cross-section of exhaust pipe. The shutters diminished active flow „window“ for 50% of normal crossection area of the exhaust pipe The plan of measurements encompasses registration of Instantaneous Angular Speed of the engine’s shaft and parallel registration of Instantaneous Value of Shaft Torsion, what reflect fluctuation of torque. Value of angular speed and toque enables exact calculation of power produced by the engine. Experiment included measurements at different levels of engine’s load and with changes of mean rotational speed. Angular speed and shaft’s torsion were measured and recorded using system ETNP-10 which is based on optical sensor and set of toothed discs. That method gives high accuracy of angular speed and torsion measurement. Results of experiment are presented as difference of related curves of values’ variations of angular speed and torsion occurring at the propulsion shaft connecting the engine and the water brake.

Opis:: The paper presents results of the calculation, based on simplified engine model, aimed on prediction of IAS (Instantaneous Angular Speed) of the crankshaft fluctuations under faulty engine condition. Gas forces were calculated basing on results of in-cylinder pressure measurements which were used as inputs to the dynamic model. Mass forces were calculated basing on technical particulars of the engine Sulzer 3Al 25/30.Measurements of the incylinder pressure was carried out at laboratory stand in Gdynia Maritime University, equipped with diesel engine Sulzer 3AL 25/30 driving electro-generator. Sulzer 3AL 25/30 is three cylinder, medium speed, four stroke marine diesel engine, with maximum output 408 kW at 750 rpm. In order to evaluate of IAS model utility for diagnostic prediction of the engine behavior, two kinds of malfunctions of engine’s fuel system were simulated. First malfunction was fuel leakage from high pressure line; the second was partly plugged injector’s nozzle. Construction of high pressure fuel pump enable to fuel leakage simulation. The engine was run out at load 250 kW what is around 65% of nominal. Results of all measurement were smoothed in order to eliminate a noise using SG (Savitzky – Golay) filter. Results of fault condition modeling were compared with healthy engine model and with results of in -cylinder pressure diagrams, in order to create a map of deviations from normal condition.

Opis:: In the paper has been presented the analysis of diagnostic utility of signals, deriving from torque (measured value is an instantaneous shaft's torsion angle, torque value is subsequently calculated basing on shaft's steel Kirhoff's modulus or Young's modulus values) and angular acceleration of the propulsion shaft. All measurements has been carried out using photo optic torque meter ETNP-10, which was installed at the propulsion shaft run by two-stroke low speed marine diesel engine. In order to distinguish diagnostic signals, measurements of healthy engine run and subsequently simulations of a failure by one cylinder cut-off (suspending of a fuel pump) were done. Analysis of torque, revolutionary speed, angular acceleration were and subsequently, in order to distinguish spectral attributes of above functions, fast Fourier transform of speed waveforms were carried out. Diagrams presented in the paper shows comparison of mentioned above signals' waveforms. The most significant influence of simulated combustion process deviation at a signal's variation was noticed when rotational speed and angular acceleration of the shaft were considered. Acquired results of research and measurements are to be a subject of further analysis in order to define representative symptoms and diagnostic values corresponding to propulsion system and engine failures.

Opis:: The paper presents results of the experiment, aimed on finding the answer whether IAS (Instantaneous Angular Speed) and angular acceleration of the crankshaft is carrying information about quality of combustion in cylinder of the diesel engine. The experiment was carried out at laboratory stand in Gdynia Maritime University, equipped with diesel engine Sulzer 3AL 25/30 driving electro-generator. Sulzer 3AL 25/30 is three cylinder, medium speed, four stroke marine diesel engine, with maximum output 408 kW at 750 rpm. In order to evaluate of IAS utility for diagnosis of the engine, two kinds of malfunctions of engine's fuel system were simulated. First malfunction was fuel leakage from high-pressure line; the second was partly plugged injector's nozzle. Construction of high-pressure fuel pump enables to simulate fuel leakage. The level of leakage was controlled by simultaneous measurement of pressure in the high-pressure tube. For simulation of injector malfunction, the chocked one was installed in second cylinder. The engine was running at different loads, starting from around 25% up to 70% of nominal. The IAS was measured and recorded by the measurement system ETNP-10, which mode of operation was based on perforated disc mounted at the shaft and photo-optic sensor counting laser impulses. Results of all measurement were smoothed in order to eliminate a noise. Measurement results of fault condition were compared with healthy engine measurements and with results of in-cylinder pressure diagrams, in order to detect all deviation from normal condition.

Opis:: The paper presents results of the experiment focused on detection of faulty injector of medium speed diesel engine, in way of analysis of IAS (Instantaneous Angular Speed) of the crankshaft. The experiment was carried out at laboratory stand in Gdynia Maritime University, equipped with diesel engine Sulzer 3AL 25/30 driving electrogenerator. Sulzer 3AL 25/30 is three cylinder, medium speed, four stroke marine diesel engine, with maximum output 400 kW at 750 rpm. In order to evaluate of IAS utility for diagnosis of the engine, two kinds of wrong adjustment of fuel injection valve’s spring were simulated. First malfunction was too weak spring (initial tension of 15.0 MPa against 25.0 MPa in normal condition), the second was too strong tension of the spring (35.0 MPa). The base of experiment was to angular speed recording, in three different conditions of the engine: healthy one and with two simulated malfunctions. Measurements were carried out at two different loads, respectively 150 kW and 250 kW. The IAS was measured and recorded by the measurement system ETNP-10, which mode of operation was based on perforated disc mounted at the shaft and photo-optic sensor counting laser impulses. Noise decomposition of measurement results was based on triple smoothing using Savitzky-Golay filter. IAS runs of faulty engine were compared with healthy engine measurement, in order to detect all deviation from normal condition.

Opis:: The paper presents an idea to utilize crankshaft's angular speed variation and its derivative for monitoring of trouble of diesel engine combustion quality. Measurement of instantaneous angular speed, long term recording and archive of values is enable by modern programmable logic controllers. Measurement of IAS (Instantaneous Angular Speed) is done using optical sensor and toothed disc. Advantage of this method is simple installation and constant signal. Collected data can be processed on board, basing on MS Excel formulas. Observation of changes of instantaneous speed and acceleration can not replace Main Effective Pressure measurement or vibration monitoring, but tool for early warning. When a signal of deteriorating of engine performance is obtain, more accurate diagnostic can be implemented. Expected final result will be elimination of engine's cycle's irregularity. Proposed method is at early stage of investigation and further steps to prove its utility and to develop concluding rules are to be conducted. In the paper are presented preliminary analysis of some bunches of data collected from two bulk carriers, operating in similar conditions.
W artykule przedstawiono ideę wykorzystania funkcji zmian prędkości kątowej wału korbowego oraz jej pochodnej do monitorowania zakłóceń równomierności pracy cylindrów. Pomiar prędkości chwilowej, zapis i archiwizacja wartości jest możliwa dzięki zastosowaniu sterownika programowalnego. Zalety powyższej metody to łatwość instalacji systemu oraz uzyskiwanie bieżącego sygnału. Zebrane dane mogą być obrabiane na statku, w oparciu o formuły zapisane w programie MS Excel. Obserwacja zmian chwilowej prędkości i przyspieszenia kątowego nie zastąpi typowych pomiarów takich jak pomiar ciśnienia indykowanego lub monitoring drgań, jest jednak doskonałym narzędziem do wczesnego informowania i ostrzegania. Przedstawiona metoda jest na wczesnym etapie badań i wymaga dalszych analiz w celu wykazania jej użyteczności diagnostycznej oraz określenia reguł wnioskowania. W artykule przedstawiono wstępne analizy pakietów danych pochodzących z dwóch masowców operujących w podobnych warunkach.
