Opis:: The technological process of installation of turbocharger as well as detailed analysis of chosen stages of installation having fundamental influence on the correct work of the turbocharger are presented in the article. The purpose of this article is performance of whole process of installation turbocharger as well as analysis of particularly significant stages of this process. The creature of turbocharging and it is myself this of working of turbocharger is enough simple. Difficulties appear if we put to the analysis conditions work of turbocharger: high temperature offumes, variable loads, aggressive environment of combustion gases, high rotatory speeds of rotors. Some of exploitation problems are possible to the elimination on the design stage or by means of application of appropriate materials. However technological process of installation is responsible for output quality and failure-free lasting work of turbocharger. In the process of installation it can distinguish some essential stages: processing and installation of shaft with the turbine's rotor, the weighing of turbine's rotor and the compressor, the installation of rotor's group, weighing of rotor's group in the trunk, positional tests under load. High rotary speeds cause during work of rotator so that created during of installation of turbocharger inappropriate balancing can bring to important damages of turbocharger. The correct course of process of installation and the final verification on braked position allows to avoid most of breakdowns of turbocharger group as well as to ensure long term of correct exploitation.From this reason very important is detailed analysis of respective stages of installation of group.

Opis:: The experimental study was conducted to investigate the effects of different opening ranges of waste gate of a turbocharged medium displacement spark ignition engine on improving work parameters such as exhaust emission, torque characteristics and fuel consumption. The object of the experimental tests was an engine with modified intake and exhaust manifolds. The intake and exhaust manifold modification included only implementation of turbocharger with the variable geometry turbine. The values of boost pressure were controlled by the system with waste gate valves with a changeable characteristic and a control valve. Work parameters of waste-gate valves have been selected experimentally. Boost pressure had to be reduced to 1.3 and to 1.5 bar in the range of medium values of throttle opening. The system with waste-gate allowed to increase significantly the torque value at low engine speed range as well as to reduce the boost pressure at high engine speed range for throttle opening values above 50%. In total range engine work, emission of particular exhaust gas components did not exceed the values of the emission suitable for normally aspirated engine. It provided the stable engine 's running in all conditions including variable engine speed and in the whole range of throttle opening angle with restricted fuel consumption. The application of changeable characteristics in the waste gate valve which reduces the charging pressure by controlling characteristics variable of the valve depending on the engine work parameters was controlled by electronic system. The controlled system allows improving parameters of engine performance in wide range of engine's rotation speed.

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:: Safe operation of a merchant vessel is dependent on the reliability of the vessel’s main propulsion engine. Reliability of the main propulsion engine is interdependent on the reliability of several subsystems including lubricating oil system, fuel oil system, cooling water system and scavenge air system. Turbochargers form part of the scavenge sub system and play a vital role in the operation of the main engine. Failure of turbochargers can lead to disastrous consequences and immobilisation of the main engine. Hence due consideration need to be given to the reliability assessment of the scavenge system while assessing the reliability of the main engine. This paper presents integration of Markov model (for constant failure components) and Weibull failure model (for wearing out components) to estimate the reliability of the main propulsion engine. This integrated model will provide more realistic and practical analysis. It will serve as a useful tool to estimate the reliability of the vessel’s main propulsion engine and make efficient and effective maintenance decisions. A case study of turbocharger failure and its impact on the main engine is also discussed.

Opis:: The purpose of the investigation was the application of two turbochargers system in spark ignition engine and determining turbochargers' work parameters depending on throttle opening and engine's rotation speed. System with small turbocharger and larger variable geometry turbocharger in parallel connection (three-stage turbocharging) was examined. The engine used during the investigation was 1300 cm displacement SI engine with modified intake and exhaust manifolds. Intake and exhaust manifold modification including only implementation of turbochargers and sensors was done for experimental purposes. Specific values of maximum boost pressure were obtained by introducing a waste gate valve system with appropriate characteristic. Proper choice concerning work parameters of the charging system allows to improve torque characteristic in wide range of engine's rotation speed. The system with additional small turbocharger allowed to increase torque value in low engine's speed range as well as to increase boost pressure in high engine's speed range for throttle opening angle values above 50 %. In medium engine's speed range the best results were given by variable geometry turbocharger. The two turbochargers system and values of maximum boost pressure were controlled by the system with two waste gate valves. Improving total efficiency was obtained in medium engine's speed range. The application of two turbochargers system as modification of naturally aspirated spark ignition engine allows to improve torque flexibility rate. There is a possibility to apply the charging system with two turbochargers, with boost pressure control system, in already existing, naturally aspirated engine without decreasing compression ratio and modifying engine's control system.

Event Tree Analysis

Opis:: The subject of the article is the identification of factors behind the incorrect operation of a car turbocharger that, in longer perspective, lead to the damage of the device. Due to the operating principle and design features, the device works with many engine systems – intake, exhaust, lubrication systems and also, increasingly more often, with the cooling system. A multitude of relations, complexity, and working conditions are reasons due to which the device is sensitive to disturbances of quality parameters of the working media (e.g. oil). In the article based on the selected causes of damage of turbochargers, we focused on the following initiating event, concerning the bearings lubrication system, which is clogged oil strainer. The authors aims at performing an analysis allowing to increase the detectability of emerging malfunctions that lead to deterioration of operating conditions of the device. For this task tool such as ETA (Event Tree Analysis) was used. It is a tool for assessing system and process safety. It facilitates detecting potential risks, as well as relations existing between actions or events. This method explores the path from the initiating event to the outcome (most often representing the immobilization of the tested object), with particular emphasis on intermediate stages affecting the technical condition of the object. Unlike the FTA analyses, which have a deductive nature, the ETA analysis is inductive. The analysis of the obtained results, supported with validation by means of ETA, allowed proving that, given the current state of knowledge and advancements in technology, it is possible to apply additional sensors for monitoring the operation of a turbocharger. The proposed modifications were considered minor design changes that significantly increase the reliability of the device.

Opis:: Possibilities of producing cast models of turbocompressor impellers in silicon matrices by vacuum casting process are presented. Vacuum casting process enables producing cast models of impellers for precision casting. A standard model for silicon matrix making is a prototype produced with stereo lithography technique. The advantage of stereo lithographic model is its easy machinability that enables higher quality of impeller model surface. Silicon matrices enable casting of prototype models from foundry plastics, such as: casting wax, polyurethanes, polyester and epoxy resins. Properties of the plastic material used determine the shape of die parting. Because of its low strength, casting wax enforces die parting into a larger number of elements, thus enabling to pull it out without damage. The prototypes made from casting resins require considerably fewer parting surfaces. Silicon matrices enable to manufacture from several to several dozen cast patterns of prototype turbocharger impellers. The basic advantage of vacuum casting process is the shortening of prototype making time and cost, compared to traditional methods. The silicon matrixes permit casting and low-pressure injections of plastics. Some plastics may be used for producing foundry patterns for various metal alloy casting processes.

Opis:: This paper presents the results of studies on the influence of unbalance of the rotor unit of a turbocharger on its operational parameters. Identification of the study object, a turbocharger of the NAPIER C-045 type, has been performed. The experiment was carried out at a test stand identifying turbocharger operational parameters belonging to the rotor unit unbalance group. Basing on the measured values and using a mathematical model, hypothetical values of operational parameters for different loads of Diesel engines were calculated. The obtained experimental results were compared to the calculated ones. On this basis, the studied turbochargers were classified into one out of three categories describing operational utility class of a given turbocharger. The order of sensitivity of turbocharger operational parameters to the unbalance of the rotor unit was established.

Opis:: This work is the continuation of the research concerning the dynamic model of a rotating set in turbocharger. In this model masses of rotors and a shaft have been modelled as concentrated masses. The rotating set has been propped on two supports forming lateral sliding bearings with a floating ring bearing. Each bearing is designed including floating ring bearing mass. The shaft of a rotating set spins at angular velocity omega 1 whereas a floating ring bearing spins at angular speed omega 2. A mathematical model constitutes a system of differential equations, mutually coupled. The mathematical model has been solved by determining: acceleration, velocity and displacement in each knot. The paper shows the crucial influence of a bearing relative clearance on static and dynamic properties of a rotating set in a turbocharger. The authors suggest that the rotating set works stably only in these cases as for given parameters, we choose properly oil films' geometry. In the conclusion, the authors formulate proposal that might be usefulfor the designers who deal with these types of bearings. Especially, the mathematical model o f a turbocharger rotating set, work parameters of bearing knots, researches of static and dynamic properties are presented in the paper.

Opis:: Most of marine diesel engines are turbocharged. Conventional maintenance methods for engine turbochargers depend on bearings clearances checks between rotor shaft and bearing housing. Some parts of the turbocharger have to be checked on the special stands or by using endoscopic methods. Fuel oil not burnt to the end and severe engine working conditions (long time idling) led to several typical turbocharger malfunctions and damages of it in some cases. Always it is easier to prevent malfunctions than take repair works on any assets. In the paper results of main and auxiliary ship's diesel engines turbochargers diagnostic investigations are presented. Methods presented in the paper based on vibration signals processing in time and frequency domain. Using these methods for checking technical condition of the turbochargers and its rotors and bearings without stopping the engine and dismantling it is possible.
Większość silników okrętowych jest budowana, jako silniki doładowane turbosprężarką. Konwencjonalne metody diagnozowania turbosprężarek polegają na sprawdzaniu luzów łożyskowych pomiędzy wałem a tulejami łożysk. Niektóre części turbosprężarki muszą być sprawdzane na specjalnych stanowiska lub z wykorzystaniem metod endoskopowych. Niespalone do końca paliwo i ciężkie warunki pracy silnika (długotrwała praca na biegu luzem) prowadzą do występowania kilku typowych niesprawności a w niektórych okolicznościach uszkodzeń turbosprężarek. Zawsze jest łatwiej zapobiegać uszkodzeniom niż dokonywać napraw urządzeń. W artykule przedstawiono wyniki badań diagnostycznych turbosprężarek silników głównych i pomocniczych na okręcie. Metody prezentowane w referacie bazują na przetwarzaniu sygnałów drganiowych w dziedzinie czasu i częstotliwości. Stosowanie tych metod umożliwia ocenę stanu technicznego turbosprężarek wraz z ich wirnikami i łożyskami bez ich demontażu i zatrzymywania silnika.

Opis:: The main objective of this study was to design a journal bearing, such that it can withstand the forces that arise in context to increasing the length of the shaft in an automotive turbocharger. The work will also provide information on how the design changes affect the overall performance of the bearing. The design changes include the thickness of the oil film, the number of grooves, the dimension of the grooves, the number of inlets and outlets, the dimension of the babbitt and mainly the length of the journal bearing. The simulation models were created using CATIA V5 and the analysis is done using ANSYS 19.2. The flow is considered to be laminar and is calculated using Reynold’s Equation. The new concept gave insight on how the design considerations affect the pressure distribution and the pressure developed. From the results, it was interpreted that the new design can withstand the four times the pressure while distributing the pressure over twice the original design.

Opis:: This paper presents the issues related to the impact of the technical condition elements of the turbocharger system on the parameters of marine diesel engine. Turbocharger system, in addition to the injection system has a significant impact on the quality of the working process, the economics and reliability of the engine. Contamination of elements of the turbocharger system are the most common faults (24.7% of all damage to marine engines). Contamination the following relates to elements: air filters, compressor, air cooler, scavenging system elements and turbine. The detailed data follows that the contamination are usually in: flow channels supercharger – 56%, turbine flow channels – 22%, air cooler – 11%, air filter – 6%, scavenging system elements – 4%, other elements – 1%. The technical condition influence of air filter, compressor and air cooler was analyzed. The analysis was supported by the results of their own research, carried out in the laboratory on the marine diesel engine, four– stroke 3AL25/30 SULZER, supercharged turbocharger VTR160N Brown Boveri. The research was performed in the form of an active experiment to simulate contamination of particular elements of the turbocharging system. Technical condition change of the air filter, the air compressor and the air cooler have been investigated.
