Opis:: Vibro-acoustic diagnostic methods which are used on marine high-speed diesel engines with turbochargers are presented in this paper. Vibration and acoustic signals generated by turbochargers need different signal processing methods to be effective and faultless in turbochargers diagnostics. Diagnostic methods which based on vibration and acoustic signals analysis are sensitive on engine load and speed changes. Methods presented in this paper based on vibration and acoustic signals processing in time and frequency domain. Using this methods checking technical condition of the turbochargers and its rotors and bearings without stopping the engine and dismantling it is possible. Examples of radial-flow rotor turbine overgrown by carbon soot and axial-flow rotor turbine without turbine blades, sound intensity level of turbocharger and acoustic spectrum of turbocharger in octave mode acoustic spectrum of turbocharger in octave mode for two different technical conditions, acoustic and vibration signal spectrum of the turbocharger, vibration acceleration amplitude of first harmonic for three turbochargers, values of harmonic vibrations of accelerations equivalent of turbine blades number, amplitude of vibrations accelerations in frequency domain for turbocharger in good and bad technical conditions are presented in the paper.

Opis:: Indicating process of large combustion engines for both marine and industrial applications is performed using the indicating channels with valves. The impact of these channels on the values of parameters obtained from engine’s indication is significant. In previous studies, it had been shown that during exploitation accidental degradation of the indicating channels occurs. Carbon deposits, which appear in the channels, are limiting their patency. Leaks in channels connections are also appeared. Disregarded state of degradation of indicating channels will change the image of indicated pressure course, different for each cylinder of the engine. When cylinders are indicated using commercial instruments, the status of the channel is not in any way taken into account. At one gas compressing station in Poland, which has compressor diagnostic system, developed by the author, with stationary indicator, inverted IIR filter has been used. This filter is used to adjust the recorded waveforms of indicated pressure on motor-compressors GMVH type, and the filter coefficient is chosen to offset the associated throttling signal delay. Information about the delay of the signal is missing, however, in the case of popular portable indicators that do not use tags from crankshaft position. The paper presents a method for assessing the state of the indicating channel, based on the asymmetry measurement of compression course obtained after cut-off the fuel supply to the tested cylinder. The study model shows that leakage from the combustion chamber, interference in cooling and other defects cause only slight and predictable disruption of symmetry. The analysis of compression pressure course (without fuel delivery) immediately prior to each cylinder indication, in the case of positive verification, increases the reliability of diagnosis. In the case of negative verification, measure of the asymmetry could be the basis for the adjustment of acquired pressure waveforms and achieved from them parameters.

Opis:: Indicating of large marine and industrial diesel engines is made with using indicating channels in cylinder head with valves. The impact of these channels on the value of the parameters obtained from indicating is significant. However, indicating is commonly used for comparative tests assuming that this error is the same on all cylinders of the same engine in identical conditions. As a result of operation especially in cylinders with irregular combustion process the coke occurs in the channel limits its patency. It causes changes in the image of indicated pressure. In such a situation defined parameters are subject of considerable random error. In the earlier studies on the engine Sulzer type 6AL20/24 cylinder channel failure was simulated and channel chocking symptom was observed as apparent TDC shift relative to a reference mark connected with the shaft. As part of ongoing studies attempt to reconstruct distorted pressure curve by chocked indicating channel was made. It is assumed that the channel with the valve is only connection between throttling element in the form of a channel with the much greater volume of the valve. Such a structure was modeled as IIR filter. For this type of filter, there is an unequivocal inverse transformation, which, at least in theory gives possibility to reconstruct the distorted pressure waveform. The reconstruction was carried out by selection of the filter coefficients so as to eliminate the shift of TDC. In practice it turned out that the reconstruction is not perfect. All obtained pressure waveforms are slightly noisy and distorted in the first phase of expansion. Despite this, there was a significant reduction in errors of some parameters determined from the reconstructed pressure waveform.

Opis:: The aim of analysis presented in the article is results of measurements of torsional deflections of a crankshaft of three-cylinder internal combustion diesel engine. The wavelets of the run of torsional twists were processed by decomposition to harmonics using FFT. In order to exactly recognize all dynamic aspects of gas forces acting during working stroke, decomposition was done in two ways: first one relaying on records encompassing one working cycle (two revolutions), the second one based at separated periods encompassing angular an interval from TDC (Top Dead Centre) of one cylinder to TDC of subsequent in firing order. For three-cylinder engine, width of the interval is 240 degrees of crank angle. In order to obtain reliable results, torsional deflection signals acquisitions were recorded numerous times including changes of outer conditions (temperature, atmospheric pressure) and different values of the engine loads. The main goal of conducted experiments was looking for an answer of a question if exist any differences between frequency spectrums of harmonics of run of full cycle ( two revolutions) and the same cycle divided by three separate intervals. Analysis was conducted in order to state any possibility of diagnostic signals acquisition caused by abnormalities of combustion process. Results were presented in form of comparison of frequency spectra taken from full cycle and divided intervals.

Opis:: Continuous monitoring of diesel engine performance under its operating is critical for prediction of malfunction development and subsequently functional failure detection. Analysis of Instantaneous angular Speed (IAS) of the crankshaft is considered as one of non-intrusive and effective method of detection of combustion quality deterioration. The paper contains presentation of attempt of monitoring of piston engine’s crankshaft torsional vibrations by measurement of Instantaneous Angular Speed at free and power output ends of the engine. It is assumed that calculation of differential value of angular distance run between both ends in the same time shall give the picture of torsion angle magnitudes and phases of the peak values. Fir carrying out such measurements, high frequency of sampling was required. The angular speed measurements is to be done utilising two optical sensors for reading and two perforated discs mounted at shaft’s ends playing the role of speed signal emitters. In the paper is presented description of the measurement system and explanation of its mode of work. It is also shown analysis of measurement accuracy, way errors elimination and method of signals runs filtration. Presented results of experiment derives from test cycle carried out using laboratory stand of Gdynia Maritime University equipped with 3- cylinder self - ignition engine, powering electric generator.

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:: The article describes processing method of a signal, coming from torsional deflections of an internal combustion piston engine’s crankshaft, registered using two optical encoders ETNP-10. Standard measurement and recording set ETNP-10 enables recording of Instantaneous Angular Speed values encompassing 10 revolutions of the crankshaft, what is equal to 5 cycles of four-stroke engine. That time duration is sufficient for analysis of changes of angular speed caused by, for example, malfunction of fuel injection valve, but is insufficient in case of observation characterized by low frequency changes with period of fluctuations, lower than 0.8 sec. Short time for recording makes impossible following of instantaneous angular speed deviations caused by magnitude modulation of engine’s load value. In the article is presented an algorithm written in MATLAB environment, which allows processing of the data recorded using the recorder DAS 1600 Sefram. The recorded this way signals have around 26 seconds' duration of engine work. Data acquired from two encoders mounted at opposite sides of the shaft, in form of square magnitude signals are transformed into instantaneous speed and subsequently to instantaneous angular shift, what is basis for torsions calculation. In the article is also presented method of elimination of systematic error due to assumed method of averaging. Finally, some examples of results of torsional deflection measurement and analysis are presented.

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:: Checking and tuning of the fuel injection valves opening pressures, fuel valves timing and exhaust or inlet valves clearances is a common practice in high-speed marine diesel engines maintenance. Cost lowering tendency in engine maintenance schedules and unmanned vessel's propulsion plants need new approach to these old and reliable procedures. Conventional maintenance methods for engine valve gear mechanism depend on valve clearances checks between valve stem and rocker arm and valve timing diagram checks on crankshaft flywheel. But how to observe valves' timing diagram on working engine and what is the difference between static and dynamic valves timing diagram and in the end how engine load and speed changes disturb observed parameters? Answers for these and other questions for high-speed marine diesel engines MB820 type are given in this paper. Dynamic valve gear timing diagrams are indispensable to perform an accurate engine tuning. A new original diagnostic and tuning method for high-speed marine diesel engine MB820 is presented in the paper. In the principle this method based on measurements of: internal cylinder pressure curves and on vibration signals. Typical diagnostic methods which based on vibration signals analysis are sensitive to engine load and speed changes. Researches presented in this paper were focused on the possibilities and differences of the dynamic timing diagram assessing at engine rated load and when idling.

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.
