Opis:

Research of usefulness of fuels for long-term storage is an important research of products of special use (meant for stock keeping as national or military reserves). Important fact is that fuels after storage should be used according to their initial use so their phisico-chemical and exploratory properties should remain the same during the whole storage cycle. Basic condition, enabling to foreseen that fuel will keep its quality at sufficient level in certain timeframe should be positive results of ageing tests. Below the doubts are presented whether methodology of evaluation is correct because of important differences in mechanisms of accelerated laboratory tests as well as real storage in typical conditions of storage tanks with large capacity. Differences in courses of chemical reactions and conditions of their initiation and course were pointed out. Scheme of equipment for marking content of existing gums, scheme of equipment for testing induction period, scheme of filtering and oxidizing equipment to test resistance of fuel to oxidation, effectiveness of collisions of molecules of reactants, scheme of chemical ageing process of fuels storaged in different temperature, function for different conditions ageing process of FAME, influence of value of potential molecules energy on initializing of chemical reactions are presented in the paper.

Opis:

Successive closing down of filled-up large municipal landfill sites or those which no longer fulfil the legal regulations, compel local governments and enterprises dealing with waste disposal, to undertake activities aimed at designing and construction of new waste management plants. One of these is a municipal solid waste sorting plant where the waste stream is divided into sub-screen and screen fraction. The screen fraction after removing ferrous and non-ferrous metals, glass and other impurities and crushing to an appropriate particle size constitutes an alternative fuel. The most frequently alternative fuel is manufactured from selectively collected plastics, rubber, textiles and waste paper. Alternative fuel is also manufactured from municipal solid waste in mechanical waste treatment plants. Municipal solid waste is characterized by a non-uniform morphological composition (depending on many factors), which may result in variable parameters of the manufactured fuel. If the waste fuel manufactured in this way and supplied to cement plants does not reach certain quality standards, its price is low, or the product is not accepted for energy recovery. The work presents results of analyses of selected properties of alternative fuels generated from solid municipal waste stream with regard to the type of communes from which the waste originated (urban commune area or rural communes). Statistical analysis was conducted using Bayesian Networks. As it results from the investigations, alternative fuel manufactured from municipal solid waste is characterized by high values of variation coefficient for such parameters as: ash content, moisture and calorific value. The content of carbon, sulphur and incineration heat revealed low values of variance coefficient. The analyses have demonstrated that technological values of alternative fuel do not depend on the administrative type of the communes where the waste used for their production was collected.

Opis:

The article presents the results of laboratory combustion tests of the microbriquette obtained from useless coal (grain class of < 5 mm) generated in the production of “eco-pea” (eko-groszek) coal. The briquettes of 1.5 and 2.5 cm3 were made in a roller press of crushed coal granulation down to 2 mm, mixed with a binder and/or catalytic additives and sorbents, then dried to final moisture of about 7%. The tests were carried out on a specially designed stand enabling to determine the differential curve of the weight loss of samples heated to the ignition temperature and then burnt with laminar airflow by natural chimney draft. Comparative tests were carried out with ecopea coal from the “ZG Sobieski” mine. The results indicate that composite fuels, in the form of microbriquette, ignite faster, burn at a higher temperature and leave less ash when burned than lump coal. The greater reactivity of the briquette concerning the lump coal allows for minimizing the air rate by about 10%, which also reduces the exhaust gas volume by the same amount and the stack losses. It reduces the velocity of dust lifting, which leads to the reduction of their emission.

Opis:

The paper presents the results of investigations concerning a new method used for predicting the allowable time of storage of biocomponents – FAME. The method was based on laboratory research carried out with the use of a storage tank simulator. The aging process was carried out in the conditions increasing the reaction rate – at high temperature. There are several methods/procedures used for predicting the allowable time of storage of fuels and biocomponents – FAME, but all of them are based on tests at the temperature so high that the mechanism of aging process is different than the one observed in storage tanks. It was assumed that the aging process could be divided into two stages: at the first stage, the aging precursors are created and at the second stage, precursors are converted into the fuel aging products. These products lead to changes in fuel properties. The kinetics of precursor creation determines the rate of all reactions, which lead to the final aging products. It was found that the rate of reaction at the first stage of fuel aging can be effectively increased by an increase in temperature and even relatively high temperature does not change the mechanism of the creation of aging precursors. The method that has been worked out makes it possible to control the mechanism of aging process during quick laboratory tests. The products of aging processes were detected with the use of the IR-VIS spectrometry. The allowable time of storage was determined for several FAME samples on the basis of quick laboratory tests. The results of laboratory quick tests were verified by comparing them with the results of the aging process of FAME in storage tanks. On the basis of the test results, the algorithm of allowable time of FAME storage calculation was worked out.

Opis:

The general principle of internal combustion engine operation has not changed since the engine structure was first developed. However, the system of blending the air and fuel into a mixture with the parameters ensuring effective fuel combustion processes has been evolving over the years. In the simplest engines, the fuel-air mixture was produced in the inlet manifold i.e. in the carburettor systems while the more advanced motors were equipped with the system of Single Point Injection (SPI), and further on with the Multi-Point Injection (MP!) where each of the cylinders has its own individual injector. The Multi-Point Injection (MPI) system has evolved into a Gasoline Direct Injection (GDI) system where the injector sprays fuel directly into the combustion chambers. Presently, due to the restrictive regulations governing the issues of exhaust gases ' composition and emissions, manufacturers of the engines used mainly in the automotive industry apply the system of multi-point indirect injection to the intake manifold or the system of direct fuel injection to the combustion chambers. In both systems, these are the injectors dosing precise amounts offuel, which are the most important, and the most accurate elements of the system. The article presents the injectors' macro- and microscopic parameters used for the purpose of the fuel dispersants' technical condition and performance assessment. Additionally, it refers to direct and optical methods of microscopic parameters measurement enabling fuel spray diagnostics.

This paper presents a study on nitrogen conversion in oxy-fuel coal combustion in a pilot scale CFB 0.1 MWth facility. The paper is focused on fuel-N behaviour in the combustion chamber when the combustion process is accomplished under oxy-fuel CFB conditions. The analysis is based on infurnace sampling of flue gas and calculations of the conversion ratios of fuel-nitrogen (fuel-N) to NO, NO2, N2O, NH3 and HCN. For the tests, O2/CO2 mixtures with the oxygen content of 21 vol.% (primary gas) and with the oxygen content varied from 21 to 35 vol.% (secondary gas), were used as the fluidising gas. Measurements were carried out in 4 control points located along the combustion chamber: 0.43 m, 1.45 m, 2.50 m and 4.88 m. Results presented below indicate that an increased oxygen concentration in the higher part of the combustion chamber has strong influence on the behaviour of fuel based nitrogen compounds.

Opis:

An idea of using biomass for generating electricity and heat leads to new solutions for power generators, adapted to be supplied with gaseous and liquid biofuels. At present, there is a growing interest in low-power generators. This type of energy production is termed 'scattered energy generation'. It is expected that generating energy in small units situated close to energy consumers may bring about substantial benefits. It is assumed that in a scattered energy generation system, energy will be produced from local fuels, such as broadly understood biomass as a primary component for production of gaseous and liquid biofuels to power low-power energy generators. An adequate amount of biomass must be secured to ensure that biogas can be produced all year round. The easiest way to store highly efficient biomass is to ensile maize and rye as well as grass. The amounts of biogas obtained from these two types of silage are comparable. Using rye as a renewable energy source for production of either bioethanol or biogas is economically viable for at least two reasons: rye grows on poor class soils and rye cultivation technology can be reduced to just nitrogen fertilization. In conclusion, it seems reasonable to generate energy in Poland in scattered energy generation systems from crops grown for this purpose. Currently, gas-powered engines are being in several ways.

The article summarizes the types of hydrogen sources and the possibilities of using hydrogen in fuel cell technologies. The types of hydrogen fuel cells and solutions used in hydrogen powered drives were discussed. The current economic and ecological aspects affecting the possibilities and profitability of using various types of hydrogen as an alternative fuel in various forms of transport were analyzed, and forecasts for the development of this form of propulsion and power supply in transport for the coming years were presented. It was concluded that only a simultaneous increase in hydrogen production, through an increase in demand or technological development, combined with a decrease in the cost of hydrogen cells down to a level of at least $40/kW, would enable the proliferation of hydrogen technologies in all modes of transport.

Opis:

The perspective of nuclear energy development in the near future imposes a new challenge on a number of sciences over the world. For years, the European Commission (EC) has sponsored scientific activities through the framework programmes (FP). The lead-cooled fast reactor (LFR) development in the European Union (EU) has been carried out within European lead-cooled system (ELSY) project of the 6th FP of EURATOM. This paper concerns the reactor core neutronic and burn-up design studies. We discuss two different core configurations of ELSY reactor; one loaded with the reference – mixed oxide fuel (MOX), whereas the second one with an advanced fuel – uranium- -plutonium nitride. Both fuels consist of reactor grade plutonium, depleted uranium and additionally, a fraction of minor actinides (MA). The fuel burn-up and the time evolution of the reactor characteristics has been assessed using a Monte Carlo burn-up code (MCB). One of the important findings concerns the importance of power profile evolution with burn-up as a limiting factor of the refuelling interval.

Opis:

The basic aim of injectors is to supply a specified amount of fuel to the turbine engine combustion chamber. The fuel should be atomized to the extent which enables its evaporation and helps to produce a homogenous mixture of fuel vapour and air, thus ensuring high efficiency of the combustion process. The article contains the review of methods and diagnostic equipment used in Aviation Overhaul Works (Lotnicze Zakady Remontowe) in assessing the suitability of turbine jet as well as turboprop and helicopter engines sprayers. Injectors are evaluated on the basis of their fuel delivery Q(p) which determines the volume of fuel sprayed in the time unit, the spray cone angle (p) and the parameter J(p) which describes the asymmetry in the circumferential spray density distribution j(). These parameters are dependent both on structural characteristics of the sprayers as well as on fuel delivery pressure p in the fuel supply pipe. In the standard diagnostic stations, the measurement of fuel delivery Q(p) is carried out only for the two fuel supply pressures, corresponding to the extreme engine ranges, that is the rotational speed of the idle running nbj and maximum rotational speed nmax. Injectors undergo the leak test at the fuel pressure 5 to 10 times bigger than the nominal value. Tolerances adopted by the producers for the measured parameters characterizing the injectors are also presented.

The main aim of the study was to experimentally determine the influence of fuel blends of F-34 with biocomponents (rapeseed methyl esters and methyl alcohol) on the performance of an engine with high pressure fuel injection; Common Rail system was used as the example. The study included measurements of useful parameters of combustion and composition of exhaust gas. The studied engine was Renault G9T engine with Common Rail fuel system, fed with the following fuels: fuel base (diesel oil); aviation fuel, code NATO F-34; fuel blends of F-34 and rapeseed methyl esters of higher fatty acids; fuel blends of F-34 and anhydrous ethyl alcohol. The study showed that the parameters of Renault G9T engine with high pressure injection system fed with fuel blends of F-34 with biocomponents changed in comparison to those obtained with the use of the fuel base: diesel oil. As a result of the study it must be stated that fuel blends of F-34 with RME and F-34 with ethyl alcohol can be used as alternative fuel for diesel engines with high pressure Common Rail injection system.

Problems of the power supply in military vehicles grow with the growing number of vehicles in armies. Moreover, biocomponents additions which are added to the basic fuels change its properties. Therefore undertaking work to adopt engines to supply them with fuels coming from renewable sources is essential. The purpose of that research is indicating the influence of fuel feeding system on useful parameters and composition of exhaust exhaust gases of self-igniting engine Renault G9T with high pressure injection mechanism „Common Rail. The researches were conducted while the engine was supplied with six kind of the fuel: basic fuel which was diesel oil, aviation fuel coded NATO F-34, fuel mixtures: F-34 methyl esters of higher fatty acids from rapeseed oil. In the result, it can be stated that the achievements of the engine Renault G9T with high pressure injection system feed with F-34 fuel and mixtures have hanged partly. Conducted examination has showed the essential influence between the fuel and performance of Renault G7T engine with high-pressure injection system feed with F-34 fuel mixtures with methyl esters of higher fatty acids. The increase of EMKOR share in F-34 fuel caused the decrease of useful power, increase of fuel consumption and decrease of combustion smoke.

Opis:

The Liquified Petroleum Gas (LPG) is currently the only widespread and available alternative fuel used in Poland for motor vehicles equipped with spark-ignition engines. Until the end of the 1980s, the monopoly on the fuel market had belonged to petrol and diesel oils. In the 1990s this monopoly was broken by LPG. The important impulse causing increase of concern with using alternative driving fuels by drivers has always been economy issues. The Liquified Petroleum Gas has been presented as an eco-friendly fuel, and with an attractive price it has also gained the title of an economical one. Over the last three decades, The Liquified Petroleum Gas has become an important player in the fuel market. The article presents current trends observed in the fuel market (LPG fuel and gasoline U95) used to power motor vehicles equipped with spark ignition engines, and analysis of the price volatility of these fuels in the period 2005÷2016.

Opis:

Since the mid 1990s, resulting from concerns on climate change and its connection to the emission of greenhouse gases, the main interest in alternative fuels has been concentrated on fuels from biomass or rather carbon dioxide neutral fuels. Autumn 2001 the European Commission presented a draft communication and two directive proposals concerning the promotion of using bio fuels and other renewable fuels and also on the taxation of bio fuels. In May 2003 a directive for promotion of bio fuels and other renewable fuels came into force. On the basis of acquired information and own work the contribution involves review of national standards concerning alternative motor fuels. In connection with gradual introduction of the alternative motor fuels, research and development in this field in the time of anticipation of the European standards generation is presented.

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 analyses the reasons for the interest in natural gas as a potential marine fuel to replace the existing fuels derived from crude oil. The increase in environmental awareness and the effects of human activity caused the process of searching for more environmentally friendly fuels. Naturally, interest has been shifted to a well-known energy source commonly found on Earth in quantities much more considerable than crude oil. This fuel, in the form of liquefied natural gas, seems to be an attractive substitute for the currently dominant types of marine fuels. The technologies of its extraction, liquefaction, storage and transport were mastered, and marine engines were adopted for its combustion as dual-fuel engines. The regulations introduced by the International Maritime Organization and the European Parliament, forcing the reduction of emissions of harmful substances into the atmosphere from the combustion of marine fuels, require taking action to meet them. The proposals for individual next 30 years are given. Due to the introduction of regulations to reduce carbon dioxide emissions, it is necessary to switch to fuels with a lower or zero carbon content or biofuels recognised as more environmentally friendly. Due to only 25% lower carbon content in methane with its higher lower heating value, it is possible to reduce the direct emission from this gas by about 30%. However, methane leaks occur in the processes from natural gas extraction to the energy effect in engines as a fuel, significantly worsening its image as an ecological fuel. Researches indicate that with current technologies, natural gas should not be recognised as an ecological fuel until gas leaks are significantly reduced. The article justifies why LNG should be considered a transient marine fuel, with the need to switch to other synthetic fuels, ammonia, and hydrogen.

The paper presents theoretical and practical aspects of prosecution of criminals involved in illegal sales of liquid fuels. It has been noticed that despite increasing attention paid to the prosecution of fuel frauds, the grey area still exists, which is due to the fact that such crimes are easy to commit, the profits to be gained are enormous, and legal consequences are rather insignificant. Recently, however, the detectability of tax frauds has increased. The improved efficiency of tax control authorities can be attributed to the introduction of the following: methodology of assessment of due diligence demonstrated by the buyers of goods in domestic transactions; JPK – the Polish equivalent of SAF-T (Standard Audit File for Tax); split payment; SENT system; fuel package.

The fuel injection phenomena belongs to the most essential processes, which are object of many experimental and theoretical works, indispensable for development of contemporary internal-combustion engines, both the spark and compression ignition. The direct injection of fotel to the engine combustion chamber belongs to most advanced solutions and must realize at least two or even more different strategies of engine performance. Article presents the various research methods of the fuel atomization processes, being concentrated on laser methods, from which deserves on the emphasis the Particle Image Velocimetry (PIV) system, the Laser Doppler Velocimeter (LDV) system and Phase Doppler Particle Analyzer (PDPA) system. Article presents theoretical analysis relating the atomized fuel stream. The results of research based on the laser research equipment are also submitted in the article. Moreover presented are the results ofresearch of the combustion process in the fixed volume chamber, where essentially two different strategies of the combustion process of homogenous and heterogeneous load were realized. The properly shaped fuel stream permits on obtainment of repeatable ignition and combustion in the wide range of the mixture variance. The essential meaning has the fuel stream disintegration, which influences advantageously on the level of the toxic exhaust elements emission, particularly on the hydrocarbon emission level because of the ignition dropout elimination and on the level of the nitrogen oxides emission because of short sojourn time of the fuel droplets in the combustion zone.

Opis:

Many new zero-emission propulsion technologies are being developed today due to the need to reduce the atmospheric carbon dioxide emissions. The impact of the transport sector on the environment drives a need for innovation, including innovation in the rail transport sector specifically. At the TRAKO fair of rail vehicles the newest technological solutions have been presented. These new vehicles are expected to take over the rail transport sector in the coming decades. Many of the presented solutions and prototypes focused on using hydrogen as fuel for a system of hydrogen fuel cells, which are then used to produce the electricity needed to drive the vehicle. The development of hydrogen fuel technologies in vehicle drives in recent years allowed for a set of new solutions to appear for all types of rail vehicles and applications. Hydrogen powered rail vehicles for transporting cargo, passengers, and shunting vehicles have been shown. This article provides a discussion of the newest hydrogen solutions and vehicles sent to the market. It was determined that the adoption of such solutions will be mainly restricted by the relative cost of the hydrogen fuel rather than the vehicles or fuel cell technologies themselves. The cost of hydrogen production, when powered by renewable Energy sources to enable reduced carbon dioxide emissions, would need to be reduced to at least $2.50 /kg of fuel in order to satisfy the requirements for widespread adoption.

Opis:

he article presents the regulations of the International Maritime Organization aimed at reducing carbon dioxide emissions from international shipping. One of the main objectives is to search the alternative to fossil fuels. The main problem is the lack of indication of the target fuel for shipping. The current changes, forced by international regulations, are made by the decisions of shipowners who themselves are looking for an alternative fuel that will enable them to continue their activities. Attempts have been made to use fuels considered as transient, which will be used in the perspective of about 10 years. However, this is too short a time compared to the life of the ship (20-30 years). This will force another change in the type of fuel used on ships still in operation, which will result in additional costs associated with the adaptation of the ship’s power plant fuel systems to a different type of fuel. The article evaluates the changes that currently taking place. Scenarios of the most likely directions of changes in a perspective of 2050 have been indicated.

Opis:

Lubricity of fuels for CI engines becomes one of very important parameter since the sulphur content was decreased to 50 and actually 10 ppm. To provide effective lubrication of fuel pumps and unit injectors elements, in case fuel does not contain organic sulphur compounds, the oxygen containing organic compounds are added as lubrication additives. Biocomponents are usually introduced into mineral diesel fuel containing additives package, which includes lubricating additive (organic acid). The aim of this paper is investigation of the influence of polar oxygenates added to petroleum diesel fuel in concentration between 5 and 20% (V/V) on lubricating additive effectiveness in protective layer creation. The results of HFRR tests obtained for blends of commercial diesel fuel containing lubricating additive with biobuthanol models (MB) leads to conclusion that: − generally the buthanol isomers addition increases wear of upper ball of HFRR apparatus, − wear of upper ball of HFRR apparatus depends on the average film thickness and does not depend on tested fuels viscosity at 40°C, − dilution of commercial diesel fuel by biobuthanol models and consequently decreasing of lubricating additive concentration cannot be the only reason of deterioration of tested blends lubricity. It was concluded, that the possible reason of lubricity deterioration by buthanol added to commercial diesel fuel in concentration between 5 and 20% (V/V) are antagonistic interactions between oxygenates (buthyl alcohol) and lubricating additive. These antagonistic interactions depend on the structure of buthanol isomers.

Opis:

The process of fuel combustion in a diesel engine is determined by factors existing during liquid fuel injection and atomisation. The physicochemical properties of the fuel to a large extent decide upon the quality of this phase of cylinder fuelling. So it is important to ensure appropriate properties of a fuel affecting its atomisation and, as a result, combustion. The paper deals with the topic of diesel oil improvers and the analysis of their influence on atomisation and combustion indices. In the studies base diesel oil and a diesel fuel improved by a package of additives, were used. The process of conventional and improved fuel injection was analysed by using optical examinations. The amount of released heat was evaluated during the studies carried out on combustion. Significant aspects of the applied improvers in relation to fuel injection and its combustion have been indicated.

Opis:

Currently produced diesel engines of different manufacturers, used for the same applications, have comparable specific fuel consumption. Therefore, the laboratories measuring fuel consumption, especially in comparative tests, require the use of more accurate methods of measurement. The Environmental Protection Centre of Motor Transport Institute has recently implemented the fuel consumption measurement method using KMA Mobile flow meter produced by AVL company. This device allows to carry out measurements by both volumetric and mass method, thanks to builtin device for measuring the fuel density. Due to some customers requirements the laboratory began with preparations for obtaining accreditation of the Polish Centre of Accreditation for the procedure of measuring fuel consumption by volumetric and mass method. One of the requirements of the Polish Centre for Accreditation is carrying out the validation of the new method. It can be done by comparing the results obtained with new method with the results of the method already validated. The validated method is described in the regulation. This is the carbon balance method described in UN-ECE Regulations No. 101. The calculation of fuel consumption according to this method is based on a measurement of pollutants emissions of carbon dioxide (CO2), carbon monoxide (CO) and hydrocarbons (THC). This paper describes the fuel consumptions measuring procedure using two methods: mass method using a AVL KMA Mobile flow meter and carbon balance method using the AVL AMA i60 analyzers. To verify measurement results additionally there was fuel consumption measured with using a scale, as a difference of the external fuel tank mass change, from which the vehicle was fuelled during the tests

Opis:

As a result of the conducted tests on the gross calorific value and the volumes of ash for fuels of Standard and Premium type available at Polish fuel distributors it was found that the tested parameters in most cases showed no substantial differences. The tests conducted with the use of a calorimeter showed relationship between the gross calorific value and the volume of the deposit that remained for both the types of fuels (the higher results of the gross calorific value the lower volume of deposit remaining after burning).
W wyniku przeprowadzonych badań ciepła spalania oraz ilości popiołu dla paliw typu Standard oraz paliw typu Premium dostępnych u polskich dystrybutorów paliw stwierdzono, iż badane parametry nie wykazują w większości przypadków istotnych różnic. Badania prowadzone przy użyciu kalorymetru wykazały zależność pomiędzy ciepłem spalania, a ilością pozostałego osadu dla obu typu paliw (im wyższe wyniki ciepła spalania, tym mniejsza ilość osadu pozostałego po spaleniu).

Opis:

The main propulsion engine is the heart of a vessel which carries the entire load of the ship and propels to move ahead. The main engine consists of various sub-systems, the fuel oil system is the most important one. Fuel oil system provides fuel to the engine via a fuel injector mounted on the engine cylinder head. During the voyage, the main engine of a ship encounters a variation in loads and stresses due to rough weather to harsh manoeuvring, which sometimes leads to the breakdown of the main engine. Fuel oil systems are identified as one of the main reasons for engine breakdown. Many accidents happened due to the failure of the main engine fuel oil system in the last two decades. To ensure safe and reliable main propulsion engine operation, it is required to assess the reliability of a fuel oil system. However, there is a significant lack of appropriate data to develop the reliability assessment techniques for fuel oil system. This study proposes appropriate data collection and analysis procedure for the reliability assessment of a fuel oil system. Data related to Failure Running Hours (FRH) of a fuel oil system is collected from 101 experienced marine engineers through a questionnaire. The collected data processed using a box plot and analysed for a normality test. It helps to identify the generalization of the data. Moreover, this study identified failure-prone components of a fuel oil system. The collected data will help in developing reliability assessment techniques for accurate reliability analysis of a fuel oil system. The identified failure-prone components will assist in future reliability analysis and risk mitigation strategies for improving the overall safety and reliability of the shipping industry.

Opis:

This investigation is devoted to an analysis of the working process in a dual-fuel low-emission combustion chamber for a floating vessel’s gas turbine. The low-emission gas turbine combustion chamber with partial pre-mixing of fuel and air inside the outer and inner radial-axial swirlers was chosen as the object of research. When modelling processes in a dualflow low-emission gas turbine combustion chamber, a generalized method is used, based on the numerical solution of the system of conservation and transport equations for a multi-component chemically reactive turbulent system, taking into consideration nitrogen oxides formation. The Eddy-Dissipation-Concept model, which incorporates Arrhenius chemical kinetics in a turbulent flame, and the Discrete Phase Model describing the interfacial interaction are used in the investigation. The obtained results confirmed the possibility of organizing efficient combustion of distillate liquid fuel in a low-emission gas turbine combustion chamber operating on the principle of partial preliminary formation of a fuel-air mixture. Comparison of four methods of liquid fuel supply to the channels of radial-axial swirlers (centrifugal, axial, combined, and radial) revealed the advantages of the radial supply method, which are manifested in a decrease in the overall temperature field non-uniformity at the outlet and a decrease in nitrogen oxides emissions. The calculated concentrations of nitrogen oxides and carbon monoxide at the flame tube outlet for the radial method of fuel supply are 32 and 9.1 ppm, respectively. The results can be useful for further modification and improvement of the characteristics of dual-fuel gas turbine combustion chambers operating with both gaseous and liquid fuels.

Opis:

The complexity of the deposit formation process on the components of compression ignition engine, including high-pressure injection Common Rail systems, is gaining global significance. Knowledge related to the mechanisms of their formation and chemical composition is still insufficient and requires further studies. The studies allowed, hypothetically, assuming several mechanisms of their formation, but each of them requires further research in order to be verified and finally confirmed. This is due to high complexity of the factors and conditions that may affect the initiation of the deposit formation, of which the most important are: fuel and additive composition and type of contaminants from fuel production and transport. Deposit physical nature may vary, as it may be soaps, salts of metals or ashless materials like imide or amide of organic polymers. This article contains the results of the research on the assessment of Common Rail injector components contamination and their technical condition, after 80 thousand km operational run, with the use of diesel and biofuel B10.
Złożoność procesu tworzenia się osadów na elementach silnika o zapłonie samoczynnym, zwłaszcza w układzie zasilania Common Rail o wysokim ciśnieniu wtrysku, zyskuje istotne znaczenie. Wiedza związana z mechanizmami ich powstawania a także ich składem chemicznym jest wciąż niewystarczająca i dlatego procesy te wymagają dalszych badań. W badaniach zakłada się hipotetycznie kilka mechanizmów ich powstawania, ale każdy wymaga dalszych analiz w celu weryfikacji dokonanych założeń. Wynika to z dużej złożoności czynników i warunków, które mogą mieć wpływ na zapoczątkowania tworzenia się osadów, z których najważniejszymi są: skład paliwa, pakiety dodatków uszlachetniających oraz rodzaj zanieczyszczeń pochodzących z produkcji paliwa i transportu. Skład fizyko-chemiczny może się różnić, ponieważ mogą one stanowić mydła, sole metali lub materiałów bezpopiołowych oraz polimerów organicznych. W artykule zamieszczono wyniki badań autorów dotyczące oceny zanieczyszczenia i stanu technicznego wtryskiwaczy Common Rail zasilanych olejem napędowym i biopaliwem B10 po przebiegu eksploatacyjnym 80 tys. km.

Opis:

In this paper, low-cost solutions were proposed to reduce the fuel consumption in a boosted port fuel injection spark ignition (PFI SI) engine, taking into account the engine performances and the pollutants emission. To this purpose, the optical characterization of the fuel injection and of the combustion process was carried out in a PFI SI engine. The experiments were performed on a partially transparent single-cylinder SI engine, equipped with a four-valve head and an external boost device. The intake manifold was optically accessible through three holes that allowed the introduction of an endoscope and of optical fibres. The standard injection condition planned by the engine manufacturer was investigated; it consisted in the fuel injection at 3.5 bar when the intake valves were closed. Moreover, the fuel injection with open intake valves was tested; 3.5 and 6.5 bar fuel pressures were studied for open and closed valves conditions. Optical techniques based on 2D-digital imaging were used to follow the fuel injection spray in the intake manifold and the flame propagation in the combustion chamber. The results of in-cylinder optical investigations were correlated with the engine performances and with the exhaust emissions.

Opis:

The article presents research results referring to the influence of supply pressure on the functional parameters of the impulse low-pressure gas-phase injector. The study was done on the original stand for flow test of gas-phase injectors. In the indirect evaluation, with the initial parameters and the length of the forced impulse, the current line, acceleration and pressure sensor courses were used. Apart from the volumetric flow rate, the analysed parameters were the time periods of the injector opening and closing process. Those time segments were composed of response time and opening/closing time, the sum of which gives time of full opening. Functional relationships describing the volumetric flow rate, time of full opening and closing are presented, which are helpful not only in comparative tests of different injectors, but also in modelling the operation of gas injector or algorithms of gas supply control system. The reference to the volumetric flow rate allowed to indicate possible causes of variability of this parameter depending on the supply pressure.

Opis:

Environmental regulations instigated the technological and procedural revolution in shipping. One of the challenges has been sulfur emission control areas (SECA) and requirement of fuel changeover. Initially, many reports anticipated that new grades of low sulfur fuels might increase various technical problems in ship operation. This research develops a simple and easy to use method of the failure severity and intensity assessment in relation to fuel changeover. The scale of failure rate in the ship’s fuel system was evaluated qualitatively and quantitively, using developed failure frequency indicator and the time between failure. Based on 77 records of fuel system failures collected on seven ships, it has been found that frequency of failures related to SECA fuel changeover is on average nearly three times higher compared to the rest of sailing time. Their severity did not significantly change, but the structure of failures changed considerably. The method and presented results may help in improvement of ship’s systems design and on-board operational procedures.
