Opis:
This paper presents a method of adjusting and designing the maintenance scheme for the high-pressure fuel pumps of a slow-speed two-stroke marine engine, MAN 6S70MC-C. The maintenance database for the marine fuel system was obtained from the planned maintenance software, and covered a period of 11 years. During this period, 29 failures occurred that required corrective actions. Our methodology includes failure mode analysis, risk analysis, reliability calculation and maintenance interval adjustment. Each failure is described using a failure mode analysis, based on a combination of the mode and cause of failure. The objective of this study is to recommend a new preventive maintenance interval based on the exponential reliability results and the analysed maintenance data. The initial maintenance plan for each fuel pump was set to 8,000 running hours, whereas in the modified plan, it is recommended to set this to 4,000 hours. Our results show an increase in the system reliability from 60% to 95% when the new modified maintenance plan is applied. In addition, the results and the recommended initial maintenance schedule are validated based on three similar types of engine with the same fuel pump system. The new maintenance approach can reduce the risk of component failure, which will lead to increased reliability of the fuel pump system and the optimisation of maintenance costs.

Opis:
This paper describes the way of modernization of the direct operation fuel feeding system of diesel engine. Effective, ecological and economical characteristics of a modern diesel engine are greatly de-termined by parameters of using fuel-feeding system. Thus, in modern conditions, fuel-feeding systems have to fulfil specified requirements, which are mainly connected with fuel supply process intensification, possibility of adaptable regulation of fuel injection lead angle, cycle fuel delivering and injection characteristic at full range of engine operation regimes. At present time accumulator fuel feeding systems Common Rail type, fulfil these requirements best of all. However, despite its advantages, those kinds of systems have number of disadvantages. The main ones are high price and structural complexity of the system elements. Because of this Common Rail does not have wide using in the diesel engines with number of cylinders less than three. Although that type of diesels exactly is universal mechanical energy, source and can be used in many types of machinery, including ones with strict ecological norms. However, up to now these engines are equipped with the direct operation fuel feeding system that despite its high reliability and low price is worse than accumulator systems in the injection pressure level and possibilities of fuel feeding process control. Thus, main objective of a modernization of the direct operation fuel feeding system is topical. Speed forcing of high-pressure fuel pump was used. Maximal injection pressure is successfully increased 1.42 times. It provides intensification of fuel injection process. Implementation of the electronic control allows counting this method of fuel feeding system modernization promising for small diesel engines.

Opis:
The paper presents the results research related to the possibility of fuel injection pump diagnosis on the basis of indicator diagram. The study was conducted on a laboratory four-stroke marine engine, type Sulzer 3Al 25/30, with nominal power Nen = 408 kW at nominal rotational speed n = 750 rpm. The study was carried out according to active experiment plan, during which the engine failure of the injection system was simulated. Simulation of fuel pump leakage was completed by the opening of the adjusting screw on the pump discharge. Measurements were made at a constant engine speed of 750 rev/min for five loads: 50, 100, 150, 200, 250 kW. Measurements of pressure of combustion were performed by means of tensometric sensors of Spice Company. Based on measured pressure curves heat release characteristics were determined. The algorithm allows the determination of net heat release rate q and the net generated heat Q characteristics. Based on the obtained results it can be concluded that significant improvement in the diagnostic use of indicator diagrams can be obtained by using heat release characteristics. These characteristics are correlated with the process of fuel injection and the injection pump operation. As demonstrated in the work of analyzing the heat release rate q, it is possible to infer diagnosis on the technical condition of the fuel injection system.

Opis:
The advancement of diesel fuel injection systems is forced by the increasingly stringent exhaust emissions limits. Modern injection systems must generate fuel pressure in excess of 200 MPa, which very often leads to premature wear of the mating components. Generating high pressures results in much force load acting on the pumps. In the case of frequently applied cam-driven pumps, high loads result in significant forces caused by friction. The friction force loads the piston perpendicularly to its axis, which rules out the application of super hard but fragile materials such as ceramics. One of the possible solutions of this problem is the application of unconventional drive systems, the example of which is the hypocycloidal drive. The paper presents the results of simulations comparing selected parameters of the piston motion of the cam-driven pumps and the pumps fitted with hypocycloidal drive. The use of the CAD software also enabled identification of the force acting on the piston (force perpendicular to the piston axis) in the cam-driven pump and its lack in the pump fitted with hypocycloidal drive.

Opis:
Common rail (CR) injection systems have been universally applied in passenger car engines for twenty years. Moreover, they are applied on a wide scale in trucks, machinery and stationary engines. They have many advantages such as very good fuel spraying due to high injection pressure, injection dose distribution to several smaller, or less heat generation compared to traditional systems. At the same time, the use of this type of system involves a number of problems. They are characterized, among other things, by the high cost of manufacturing and the high sensitivity to changes in the quality of the used fuel. The most important component of the common rail injection system is the high-pressure injection pump. The authors propose a new, alternative pump design with the hypocycloid drive – the article presents the issue of using this type of pump. Further sections describe the design of a pump utilizing a hypocycloid mechanism; demonstrate beneficial functional features and present selected results of the assembly's dynamic simulation. The pump is also characterized by the possibility of multiplying the piston's pitch while maintaining its diameter. It makes it possible to obtain much greater discharge per operating cycle. Taking into account the considerable quantity of fuel transferring by the pump, was also possible to propose an idea of use of hydraulic booster in such pump. In this field, the authors have presented schematic diagram of a pressure booster with a description of its operation.

Opis:
The paper presents an analysis of the possibility of using a common rail pump to supply an aircraft compression-ignition engine. It is an engine with a two-stroke cycle, three cylinders, opposing pistons and 100 kW power. Its each combustion chamber is supply by one or two injectors controlled by electromagnetic valves. In order to assess the possibility of using a common rail pump, four high-pressure pumps were tested on a bench. They are piston pumps differing in the number and geometry of their pumping sections. The analysis included the pumping output, the torque on the pump drive shaft and the power needed to drive the pump. The weight and overall dimensions of the pump were also considered, including the arrangement of the pumping sections and the way the drive is transmitted. The research allowed to optimize the engine power supply system depending on fuel demand and the way the pump is mounted on the engine.

The article presents results of a laboratory study on exhaust gas emission level from a marine diesel engine. The object of the laboratory study was a four-stroke marine diesel engine type Al 25/30 Sulzer, operated at a constant speed. The examination on the engine was carried out according to regulations of the Annex VI to MARPOL 73/78 Convention. The laboratory study consisted of 3 observations: the engine assumed to be operating without malfunctions, delay of the fuel injection by 5° of crankshaft angle in the second engine cylinder, and the leakage of the fuel pump on the second engine cylinder. Additionally, parameters of fuel consumption and thermodynamic parameters of the marine engine were measured during the research. Simulated malfunctions caused changes in total weighed NOx, CO, and CO2 emissions for all considered engine loads. All simulated malfunctions caused a small change in measured thermodynamic parameters of the engine. The engine operation with the delayed fuel injection and the fuel leakage in the fuel pump in one cylinder caused a decrease of NOx and CO emission level. Fuel leakage in the fuel pump causes the CO2 emission to decrease only at low engine load. Calculations of the weighed specific fuel consumption present a 1-2% change in the engine efficiency.

Opis:
The experimental results of acoustic emission signals application to the investigation of the fuel injection system of a medium-speed marine diesel engine are presented. The introduced studies were confined to the phenomenon of the injection process. The features extracted from the raw acoustic emission signal were used to condition the monitoring of the main process of the injection system. The advantage of AE application in comparison to traditional methods is that the non-intrusive nature of the sensors can result in reduced set up times and cost.
W artykule zaprezentowano fragment prowadzonych przez autora badań układów wtryskowych silników okrętowych średnich mocy. Badano zjawiska zachodzące w układzie wtryskowym z wykorzystaniem sygnałów emisji akustycznej EA (znanej w lit. ang. jako acoustic emission lub stress wave emission). Za pomocą "czystego sygnału źródłowego" EA można w dokładny sposób określić procesy związane z pracą układu wtryskowego oraz układu wymiany czynnika roboczego (np. otwieranie/zamykanie zaworów dolotowego i wydechowego). Analizując sygnał pochodzący z układu wtryskowego (pulsacje I zmiany sygnału EA) wnioskować można o stanie układu iglica-prowadnica wtryskiwacza, początkach zacierania się iglicy, zmianie ciśnienia podiglicowego we wtryskiwaczu, a także o niewłaściwej pracy pompy wtryskowej. Istotną zaletą stosowanej przez autora metody jest to, że podłączenie czujnika do układu odbywa się bez jakiejkolwiek ingerencji w proces.

Opis:
Purpose: The aim of the work was to test the contact stresses in the model system of the turbine hub cooperating with the fuel pump drive shaft. The hypothesis of the work was that, by means of FEA, it is possible to assess the contact stresses in the materials of the turbine hub and the fuel pump shaft during torque transmission. Design/methodology/approach: A turbine with fibre-reinforced polyphenylene sulphide (PPS) composite cooperating with a stainless steel shaft (X46Cr13/1.4034) in a commonly used D-flat shape joint was selected for the experimental research. To assess contact stresses, the CAD model (NX, Siemens) of the entire turbine was limited to the hub area. The drive shaft is supported in accordance with the bearing in the fuel pump, and the possibility of rotation about the axis along the length of the torque-producing magnet is taken away. The system was loaded with a torque of 200 Nmm on the turbine. The turbine hub and shaft were calculated, taking into account the phenomenon of contact detachment or slip at the value of the friction coefficient of 0.1. Findings: The pressure transmission area was found in the area at the edge of the flat surface D-flat and on the opposite side of the D-convexity. The contact stresses on the D-flat side reached values close to the composite strength. Research limitations/implications: The studies did not take into account the technological inaccuracies, thermal deformation, local material properties, and wear. The value of the friction coefficient was not measured in realistic conditions with fuel lubrication. Practical implications: FEA has been achieved, which allows to reduce the cost of experimental research. Originality/value: The proposed model allows for further studies of the influence of elasticity of various materials and structures on contact stresses in order to assess wear resistance.
