Opis:: Exhaust gases from engines of seagoing ships are the serious problem for environment. That is why the discussion in the matter is very important. One of means to minimise harmful substances emission to earth atmosphere is application of „ecological fuel" — natural gas or nuclear energy for ship propulsion. Natural gas is commonly used in onshore applications but is rarely applied in marine propulsion. Heavy Fuel Oil is the basic brand of fuel used onboard ofseagoing ships. Other kinds of fuel e.g. Diesel Oil or gas Oil are used on smaller ships with limited sailing range. The nuclear energy, due to high costs is used only on few types of warships and some icebreakers. A real means for minimising harmful substances in exhaust gases from ships engines is replacement of Heavy Fuel Oil by Natural gas. Nowadays, heavy oil is commonly used due to technical and logistic abilities and conservative attitude of ship owners. The necessity of improvement in the field of environment protection inclines towards wide application of Natural gas as marine fuel. Application power-plant novel type would break the traditionalism in the shipbuilding and the introduction novel generation ofshipping drives.

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.

Opis:: Investigation on fuelling a dual-fuel compression ignition engine with various fuels, that are unconventional for this type of engine, was carried out for many years in the Department of Internal Combustion Engines and Automobiles in Technical University of Radom. Such fuels as methanol, ethanol and natural gas were applied in the investigation. Recently, the investigation regards application of LPG - a fuel that is very popular in Poland. Within the project No. 4T12D02226 of the Committee of Scientific Research, it was tested, among others, an engine equipped with injection system for diesel fuel pilot dose - a common rail type. As a result of the former investigation, load characteristics of specific energy consumption as well as CO, CO2, nox, HC and smoke emissions data were obtained [1]. In order to analyze variability of fundamental combustion process parameters, histories of the pressure inside combustion chamber have been registered during investigation. Investigation on changes of these parameters in the described engine version is particularly important due to possibility of knocking combustion occurrence that leads to the failure of such engine parts as piston or valves. Changes of these parameters versus engine load for various injection timing of diesel fuel pilot dose were analysed.

Opis:: The results of CFD modelling a dual fuel diesel engine powered with both methanol and diesel fuel is presented in the paper. Modelling was performed with 20 and a 50% energetic share of methanol in the entire dose. The analysis was conducted on both the thermodynamic parameters and exhaust toxicity of dual fuel engine. It was found that the various share of methanol influences the ignition delay of the combustion process and after start of main phase of combustion, the process occurs faster than in case of the diesel engine. It was found that the time of 10-90% burn of the fuel is much shorter than it is in the diesel engine. The dual fuel engine was characterized by higher indicated mean pressure in the whole range of diesel fuel injection timings. While analysing toxic exhaust emission from the dual fuel engine powered with methanol, it was found that the rate of NO formation was significantly higher than from the diesel engine. The combustion process in the dual fuel engine occurs more rapidly than in the conventional diesel engine, which contributes to form areas with high temperature, and in combination with presence of oxygen from the air and oxygen bonded in the methanol, promotes the NO formation. In the case of the dual fuel engine, it was found that soot emission was reduced. The engine running with diesel injection start at 8.5 deg before TDC, the soot emissions were more than twice lower in the dual fuel engine, while the emission of NO was much higher.

Opis:: Dual fuel compression ignition engine can be run on diverse fuels, both gaseous and liquid ones. Alternative fuels to the Diesel oil feature, as a rule, low cetane number and high temperature of self-ignition. Due to this, such fuels can not be ignited spontaneously and require ignition from small dose of the Diesel oil. In the dual fuel system, as the main fuel can be considered a liquid fuels, which can be supplied to the cylinder in form of vapours, or injected be to the suction manifold. Methyl and ethyl alcohols, or their esters, can be counted among future fuels. Such alcohols can be either the main fuels or small additions improving combustion of the Diesel oil. In the paper are presented test results of the SW 680 engine run on methanol and Diesel oil. Methanol was supplied to the suction manifold in form of methanol-air aerosol. Energetic fraction of the methanol amounted to 12-50%, depending on engine load. Performed tests have shown advantageous effect of the methanol on performance of the engine. One confirmed considerable growth of overall efficiency of the engine in area of higher loads (3-6%), reduction of smokiness of exhaust gases achieved as early as with small additives of the methanol (2-3 times), reduction of CO and CO2 emissions, reduction of exhaust gases temperature. Small addition of the methanol affects advantageously on combustion of the Diesel oil, shortening time if its combustion. Addition of the methanol enables maintaining effective power of the engine fuelled traditionally, and even its slight growth. Cost of adaptation to dual fuel supply with alcohol are low, and such type of fuelling can be easy implemented in already operated compression ignition engines.

Opis:: Engines working in dual-fuel mode need special conditions to ignite air-fuel mixture without spark plug in a good moment with high combustion efficiency. To create homogenous air-fuel mixture the conditions in the cylinder are even more demanding. Many concepts of ignition was developed, but the most effective needs perfect mixing of fuel and air, which is a serious technical challenge. Technical solutions for dual-fuel engines cover the complexity of these problems thus leading to the further development of ignition systems in internal combustion engines. Fuel supply systems, the operation strategy of them, the shape of the combustion chamber are the most important elements to change and develop for correct operation of dual-fuel engines. The literature analysis showed a small amount of research carried out to optimize the operation of dual-fuel engines The variety of engines in which a dual-fuel system can be used requires much more research about them, and solutions necessary for their correctly operation.

Opis:: At the moment, there is a growing interest in low-power generating units in dispersed system. The production of energy in small units located in the vicinity of the energy recipients offers considerable benefits. First and foremost, it lowers the cost of energy production and the cost of its transfer and also makes the recipient independent from the domestic supplier. Small cogeneration aggregates will facilitate the use of energy from dispersed renewable resources. Gas self-ignition engines in cogeneration system powered with biofuels can be used in construction industry as ecological sources of heat and electrical energy, limiting the need for fossil fuels. This paper presents the possibility of using alternative fuels for internal combustion engines. It describes the possibility of using liquid biofuels separately or natural gas fuel to power diesel engines in dual fuel system. The conception of supplying low-power generator with diesel engine with natural gas to a dose of liquid biofuels test case. Pointed to the factors determining the desirability of a particular concept. Indicated the modification of the engine power to supply the natural gas generator with a dose of liquid biofuels. New technologies of extracting and using biofuels and alternative fuels are being introduced and developed for generating heat and electric energy. Studies on the use of gas and liquid alternative fuels are directly linked to research on the production of renewable and alternative energy as well as environment protection by minimizing emissions of toxic substances into the atmosphere.

Opis:: The pursuit of reduced greenhouse gas emissions, as well as the increased share of renewable fuels in the overall energy balance has led to a search for alternative energy sources. One of the fuels on which great hopes are set as fuel for engines is biomethane or biogas, whose main component is methane. Biogas can be obtained from different products by using different technologies, so that it has potential as a widelyavailable fuel, which is quite easy to produce. The percentage of methane in biogas depends on the technology for obtaining biogas and ranges from 35% to around 75%. The largest biogas sources can be animal farms, where it is obtained from animal excrement. Another source is sewage treatment plants and rubbish dumps, where substantial quantities of biogas are obtained as a result of natural processes occurring in waste dumping sites or sewage. Biogas can also be acquired from waste obtained from fruit and vegetable processing as well as waste from meat plants. This paper examines the possibility of using biogas as a fuel for diesel engines. In these engines, the combustion of biogas (methane) requires the application of a dual-fuel supply system in which liquid fuel initiating gas fuel selfignition will be injected into the combustion chamber along with methane. The paper also contains example results showing the effect of the methane dose on the course of the combustion process in diesel engines.

Opis:: One of the basic problems concerning dual fuel powering of self-ignition engines is to determine the minimal dose of diesel oil injected into the combustion chamber in order to trigger self-ignition. Most research conducted to date on double-fuel powering self-ignition has been carried out on engines with mechanical injection systems, which does not ensure the possibility of obtaining very small diesel oil doses initiating self-ignition. The original system of fuelling the engine with diesel oil was replaced with a laboratory Common Rail system. The basic parameters of injector operation were controlled by a specially-developed system ensuring continuous choice of parameters of injector operation. The examined engine was fitted with a prototypical system of methane-air fuelling and a system for controlling and adjusting the supplied dose of methane This study presents the results of research aiming at determining the pilot dose injected into the combustion chamber of the engine to ensure the course of combustion in the engine operating under various loads. The results presented in the paper concern tests of a single-cylinder self-ignition engine, HATZ 1B40, operating in a generator adopted for CNG fuelling.

Opis:: Following the modern fuel market, one can notice that prices of liquid petroleum derivatives - petrol and diesel oil - which most often fuel piston internal combustion engines are increasingly higher. Similarly, the price of petroleum-derivative gas (LPG - the liquefied petroleum gas - simply speaking, a mixture of propane and butane) is also growing. Many academic and industrial institutions of science conduct research to determine whether it is possible to replace liquid petroleum-derivative fuels with some other potentially cheaper ones. It would also be beneficial if these new fuels were more "ecological" - so that their combustion products would not be harmful for the environment and if they were produced with the use of plants. Fuel stations commonly offer a fuel for diesel engines which is a mixture of fatty acids methyl esters (FAMEs) from vegetable oils, in Poland for instance from rape seeds. The paper presents a comparison of selected operating parameters of the Hatz 1B40 engine fuelled with mixtures of diesel oil or liquid bio-fuel and natural gas. Indicator diagrams, exhaust gases composition and vibration signals recorded on the engine body were analyzed. The study was conducted on the Hatz 1B40 diesel engine which is used among others in FOGO power generator sets, after replacing the original feeding system by common rail system for liquid fuels and after adding natural gas feeding system.

Opis:: Dual fuel combustion has been recently of high interest, mainly in terms of utilization of fuels different than diesel fuel in compression ignition engines. Depending on the properties of a fuel which is additional to diesel fuel, and the type of the additional fuel supply method the combustion process may be strongly modified comparing to single fuel combustion. Nowadays the modification of the combustion process becomes the reason for implementing the dual fuelling process. However, still the main reason for its implementation remains the utilization of nonconventional fuels in compression ignition engines. Among different types of dual fuel systems the one based on simultaneous direct injection of two fuels seems to be most flexible one. It allows to stratify the charge in the cylinder, blend two different fuels at any ratio and does not decrease volumetric efficiency. Therefore, this study aims at mixture formation in a heavy duty engine employing simultaneous direct injection of two different liquid fuels. Special attention was paid to spray breakup and simultaneous evaporation of two fuels which are the key processes in mixture formation.

Opis:: The article presents the tests results of the prototype design of hydraulically assisted injector that is designed for gas supply into diesel engines. The construction of the injector allows for its positioning in the glow plug socket, so that the gas is injected directly into the combustion chamber. The cycle analysis of the four-cylinder Andoria ADCR engine with a capacity of 2.6 dm3 for different crankshaft rotational speeds allowed to determine the necessary time for fuel injection. Because of that, it was possible to determine the required mass flow rate of the injector, for replacing as much of the original fuel by gaseous fuel. To ensure a high value of flow inside the injector, supply pressure equal to 1 MPa was applied. High gas supply pressure requires high value of valve opening forces. For this purpose a injector with hydraulic control system, using a liquid under pressure for the opening process was designed. On the basis of air pressure measurements in the flow line after the injector, the analysis of opening and closing of the valve was made. Measurements of outflow mass of the injector were also carried out. The results showed that the designed injector meets the requirements necessary to supply ADCR engine with CNG fuel.

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:: Today, more and more attention is paid to search for alternative fuels, which would be not only environmentally friendly, but also cost-competitive to petroleum fuels. In the recent years much attention is paid to investigations at adaptation of combustion engine to run on bio-fuels. Results of the investigations show, that methyl and ethyl alcohols could belong to one from the most promising and future bio-fuels, being a serious alternative to petroleum fuels. Interest in these fuels comprises such areas as exploration of raw materials to production of the alcohols, development of technology of their production, especially 2nd generation of ethyl alcohol, special fuelling and control systems, design changes of the engines fuelled with alcohols. In the present paper are shown test results of Fiat 1.3 Multipoint engine fuelled in dual fuel system with methanol and gasoline. In this engine one assembled prototype fuel supply system with duplex injectors on each cylinder, to injection of methanol and gasoline. Implemented system enables fuelling with gasoline only, with methanol only, or simultaneously with gasoline and methanol with any fraction of the methanol. Change of fuelling system and change of methanol fraction can be accomplished in course of engine operation. Performed investigations showed advantageous effect of the methanol on toxicity of exhaust gases. One confirmed reduction of emissions of hydrocarbons, nitrogen oxide and carbon dioxide. The biggest changes in the concentration occurred in case of fuelling with the methanol only, and amounted to: 2-3 times reduction of the THC, reduction of NOx with 40-60%. Differences in concentration of NOx increased together with growth of engine load, and hence, they concern such areas of engine operation, where the biggest quantities of the NOx are emitted. In case of dual fuel feeding, effect of reduction of concentration of the components discussed here decreases according to reduced fraction of the methanol. Changes in the emissions discussed here are obtained with maintained engine performance and growth of overall efficiency of the engine. Implemented system eliminates problems of stratification of methanol-gasoline mixture in low temperatures and in presence of water. The system can be adapted to any liquid fuels.

Opis:: Agriculture farms, especially animal farms consume a lot of energy. They also have big potential to produce energy by themselves. The production of biogas and its efficient utilisation could meet the need for fuel and energy. The production of biogas on a farm and its utilisation as a fuel could improve its energetic balance and safe some money. The paper describes the possible way of utilisation of upgraded manure biogas as a fuel for compression ignition engine, which is adopted for dual fuelling. The engine is going to be fuelled with vegetable oil ester and biogas produced directly on animal farm. Some calculation of fuel consumption of both fuels and analysis of possible changes of combustion process for dual fuelling mode are presented. There is also described the concept of adaptation of CI engine for agriculture tractor to dual fuelling with vegetable oil ester and biogas. In Poland, there are about 1300 caw farms, 3000 pig farms and about 3500 chicken farms. Taking into account that the production of biogas is efficient and give some profit for minimum 100 caws, 500 pigs or 5000 chickens in the farm, there is together about 7800 farms where production of biogas could be profitable [2]. At the end of 2009 there were only 126 installation for biogas production and they produce 70.88 MW of energy. Biogas is one of the most promising sources of renewable energy because the efficiency of conversion of biomass into fuel is relatively high.
