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:: 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:: 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:: At former KONES one of the co-authors presented a paper, is which general information about natural gas properties, reserves, production and distribution were given and application to SI and CI engines was presented, compared and discussed. It was shown, that more promising is dual-fuel CI engine. There is a lot of information on combustion, emissions and performances of dual-fuel natural gas engines, but there are also blank areas and controversial opinions, which were pointed out and discussed in this paper. For example: why combustion processes are delayed in comparison with combustion of diesel fuel only. It is also not clear whether noise of dual-fuel engine is higher than that of diesel engine or lower (there are contradictory data). These problems are shown and discussed in this paper. The proposal of further research is presented. Ignition and combustion in dual-fuel natural gas engines is yet not fully recognized, especially: combustion duration, mechanism at gaseous and condensed phase burning, kinetics and diffusion controlled combustion, noise, knock and cycle-by-cycle variation. Optimization of control parameters on account of efficiency and emissions is still an open problem. Influence of natural gas composition and its changes on engine performance and emissions still demand estimation.

Opis:: Reduction of greenhouse gases emissions into the atmosphere, as well as increasing the share of renewables in the overall energy balance, forces the search for new, alternative energy sources. One of the fuels, which presents high potential for combustion engines are biomethane or biogas, with methane as the main flammable component. Biogas can be obtained from different products and using a variety of technologies which results in its wide availability and relatively easy manufacture. The largest sources of biogas can be animal farms or sewage treatment plants and waste dumps in which significant quantities of biogas are obtained as a result of naturally occurring processes. Biogas can also be obtained from processing of energy crops or waste processing in agricultural, food and meat processing plants. In this article, the possibility of using biogas as a fuel for CI engines has been examined. In such engine, combustion of biogas (methane) requires the use of dual fuel supply system, in which in addition to methane, liquid fuel is injected into the combustion chamber, in order to initiate the self-ignition of gaseous fuel. The paper presents exemplary results of the impact of the proportion of different fuels and biogas composition on the efficiency of the engine work cycle.

Opis:: This paper concerns analysis of possible use of alcohols for the feeding of self - ignition and spark-ignition engines operating in a dual- fuel mode , i.e. simultaneously combusting alcohol and diesel oil or alcohol and petrol . Issues associated with the requirements for application of bio-fuels were presented with taking into account National Index Targets , bio-ethanol production methods and dynamics of its production worldwide and in Poland. The considerations are illustrated by results of the tests on spark- ignition and self- ignition engines fed with two fuels : petrol and methanol or diesel oil and methanol, respectively. The tests were carried out on a 1100 MPI Fiat four- cylinder engine with multi-point injection and a prototype collector fitted with additional injectors in each cylinder. The other tested engine was a SW 680 six- cylinder direct- injection diesel engine. Influence of a methanol addition on basic operational parameters of the engines and exhaust gas toxicity were analyzed. The tests showed a favourable influence of methanol on combustion process of traditional fuels and on some operational parameters of engines. An addition of methanol resulted in a distinct rise of total efficiency of both types of engines at maintained output parameters ( maximum power and torque ). In the same time a radical drop in content of hydrocarbons and nitrogen oxides in exhaust gas was observed at high shares of methanol in feeding dose of ZI ( petrol) engine, and 2-3 fold lower smokiness in case of ZS ( diesel) engine. Among unfavourable phenomena, a rather insignificant rise of CO and NOx content for ZI engine, and THC and NOx – for ZS engine, should be numbered. It requires to carry out further research on optimum control parameters of the engines. Conclusions drawn from this work may be used for implementation of bio-fuels to feeding the combustion engines.

Opis:: In the near future, natural gas may become a fuel, which will see increased use in powering internal combustion engines. Due to its properties, it can be used to power spark-ignition engines without major obstacles. Yet using natural gas to power compression-ignition engines proves to be more difficult. One of the possibilities are the dual-fuel compression-ignition engines running with gas fuel and diesel fuel, enabling ignition through compression and combustion of gas fuel. The article presents the heat release characteristics of the Perkins 1104D-E44TA engine powered by compressed natural gas and diesel fuel. Characteristics of heat release are an image of the combustion process. They affect the engine performance indicators. The determined heat release characteristics for a dual-fuel-powered engine were compared with the heat release characteristics for a diesel engine under the same operating conditions. An analysis of heat release characteristics was carried in the scope of their influence on the concentration of nitrogen oxides in the exhaust of the tested engine. The effect of the relative amount of heat released and the heat release rate during the combustion process in the Perkins 1104D-E44TA engine cylinder running dual-fuel with CNG+diesel on the concentration of nitrogen oxides in the exhaust, as compared to the values measured when running with diesel fuel only, was demonstrated. Higher share of natural gas in the total amount of energy supplied to the engine cylinders results in greater differences in the course of the combustion process and result in a greater reduction in the concentration of nitrogen oxides in the exhaust of the tested engine.

Opis:: Gaz ziemny jako paliwo do zasilania tłokowych silników spalinowych stanowi ciekawą alternatywę dla benzyn i olejów napędowych. Jest źródłem energii, która jest promowana przez Unię Europejską, w celu zwiększenia jej udziału w transporcie. Dostępne są technologie, które pozwalają na stosowanie gazu ziemnego do zasilania silników o zapłonie wymuszonym, jak również silników o zapłonie samoczynnym. W artykule przedstawiono wybrane wyniki badań silnika o zapłonie samoczynnym Perkins 1104D-E44TA, który został przystosowany na hamowni silnikowej do zasilania dwupaliwowego sprężonym gazem ziemnym i olejem napędowym. Podczas badań silnik pracował według zewnętrznej charakterystyki prędkościowej. Wyznaczone wybrane wskaźniki pracy silnika Perkins 1104D-E44TA przy jego zasilaniu dwupaliwowym, jednocześnie gazem ziemnym i olejem napędowym, porównano z wskaźnikami otrzymanymi przy zasilaniu silnika tylko olejem napędowym. Uzyskano nieznaczne zmniejszenie mocy efektywnej i momentu obrotowego silnika przy jego zasilaniu dwupaliwowym. Poza tym zasilając silnik dwupaliwowo uzyskano zwiększenie godzinowego zużycia paliwa, jednostkowego zużycia paliwa i godzinowego zużycia energii, w porównaniu do jego zasilania olejem napędowym.
Natural gas used as a fuel for piston combustion engines is a noteworthy alternative to petrol and gas oil. This source of energy is promoted by the European Union in order to make it more prevalent in transport. There are available technologies which make it possible to use natural gas for powering positive-ignition and compression ignition engines. The article presents test results for the Perkins 1104D-E44TA compression ignition engine, which was adjusted for dual-fuel compressed natural gas and Diesel fuel feed. During the test, the engine was working according to an external speed characteristics. The motor action indicators of the Perkins 1104D-E44TA, powered with both natural gas and Diesel fuel, were compared with the indicators when the engine was propelled only with Diesel fuel. The result was that the brake horsepower and the torque were slightly decreased when the engine was being bi-fuelled. Furthermore, when compared to running on Diesel fuel only, the engine propelled with both types of fuel increased fuel consumption per hour, specific fuel consumption and energy consumption per hour.

Opis:: The occurrence of knocking combustion is one of the basic problems of dual-fuel compression-ignition engines supplied with diesel oil and gaseous fuel. In order to detect this phenomenon and evaluate its intensity, several methods are commonly used, including the analysis of pressure of working medium in the combustion chamber of the engine or vibrations of certain engine components. This paper discusses the concept of using mass fraction of hydroxyl radicals as the indicator of the occurrence of knocking combustion. Current knowledge on the conditions of hydroxyl radical formation in the engine combustion chamber has been systematized and the results of research on this subject have been presented. Theoretical considerations are illustrated by exemplary results of simulation studies of the combustion process in a dual-fuel compression-ignition engine supplied with diesel oil and methane. The conclusions drawn may be useful for the development of dual-fuel engine control systems.

Opis:: Konwersja silnika diesla na zasilanie dwupaliwowe olejem napędowym i gazem ziemnym wiąże się ze zmniejszeniem kosztów eksploatacji. Jednakże w przypadku pośredniego wtrysku gazu do układu dolotowego pojawiają się ograniczenia w ilości zastąpienia oleju napędowego paliwem gazowym. Związane jest to ze zwiększoną emisją składników toksycznych spalin oraz z zagrożeniem wystąpienia spalania stukowego. Wynika to m.in. z przedostawania się niespalonego gazu do układu wylotowego spalin oraz z małym uwarstwieniem mieszanki w komorze spalania. Alternatywą dla takiego sposobu zasilania jest wtrysk bezpośredni gazu do komory spalania. W artykule przedstawiono wyniki badań trójwymiarowego modelu dwupaliowego silnika diesla z wykorzystaniem oprogramowania AVL FIRE. Wykonano analizę procesu tworzenia mieszanki w silniku zasilanym pośrednim i bezpośrednim wtryskiem gazu.
The operation of the Diesel engine becomes cheaper when such an engine is converted to run on a Diesel oil and natural gas. However, if a gaseous fuel is directly injected into an intake system, the amount of a Diesel fuel to be replaced by a gaseous fuel is limited. This is due to the increased emissions of toxic compounds in exhaust gases and the risk of knocking as a result of entering an unburnt amount of a gaseous fuel into an exhaust system and a negligible mixture stratification in a combustion chamber. The direct injection of a gaseous fuel into the combustion chamber is an alternative method. The paper studies mixture formations for an indirect and direct gaseous fuel injection in an AVL FIRE 3D model of a dual-fuel Diesel engine.

Opis:: Liquefied natural gas (LNG) qualifies as sustainable and secure marine fuel that is reliable in supply. The international standards (IGF Code) and classification regulations have been aligned. First experiences in ship operations and design are now available. Initial reports from the practical ship operations show that the lack of knowledge and misjudgements of original equipment manufacturers (OEM’s), suppliers, consulting services and flag state authorities have led to operational restrictions or expensive retrofitting. The aim of this paper is to illustrate first experiences and operating instructions using this new and different marine fuel; derive recommendations for instructions for education and training programmes at maritime colleges, universities and business partners; present action recommendations for future operational concepts.

Opis:: Protection of the environment and counteracting global warming require finding alternative sources of energy. One of the methods of generating energy from environmentally friendly sources is increasing the share of gaseous fuels in the total energy balance. The use of these fuels in compression-ignition (CI) engines is difficult due to their relatively high autoignition temperature. One solution for using these fuels in CI engines is operating in a dualfuel mode, where the air and gas mixture is ignited with a liquid fuel dose. In this method, a series of relatively complex chemical processes occur in the engine's combustion chamber, related to the combustion of individual fuel fractions that interact with one another. Analysis of combustion of specific fuels in this type of fuel injection to the engine is difficult due to the fact that combustion of both fuel fractions takes place simultaneously. Simulation experiments can be used to analyse the impact of diesel fuel combustion on gaseous fuel combustion. In this paper, we discuss the results of simulation tests of combustion, based on the proprietary multiphase model of a dual-fuel engine. The results obtained from the simulation allow for analysis of the combustion process of individual fuels separately, which expands the knowledge obtained from experimental tests on the engine.

Opis:: Artykuł dotyczy zagadnień wpływu stopnia sprężania dwupaliwowego silnika o zapłonie samoczynnym zasilanego gazem naturalnym CNG na wybrane parametry procesu spalania. W ramach badań dokonano rejestracji przebiegu ciśnień w komorze spalania w funkcji obrotu wału korbowego dla różnych wartości stopnia sprężania. Zarejestrowane charakterystyki pozwoliły na wyznaczenie takich parametrów procesu spalania jak: ciśnienie maksymalne P_max, średnia szybkość narastania ciśnienia (∆p/∆α)_śr,maksymalna szybkość narastania ciśnienia (dp/dα)_max, w funkcji momentu obrotowego M, oraz stopnia wypalenia dawki x w funkcji obrotu wału korbowego α. Analiza uzyskanych wyników wykazuje silną ich zależność od wartości stopnia sprężania ε silnika dwupaliwowego.
The present paper relates to the problem of the effect of compression ratio of a dual-fuel compression ignition engine fuelled with natural gas (CNG) on selected combustion process parameters. In the course of investigation, there were registered pressure values in the combustion chamber versus crankshaft angle for various compression ratios. The obtained characteristics enabled to determine such combustion process parameters as: maximum pressure P_max, mean rate of pressure rise (∆p/∆α)_śr, maximum rate of pressure rise (dp/dα)_max, versus torque M, as well as fuel burnout ratio x versus crankshaft angle α. Analysis of the results indicates strong relationship between the above mentioned parameters and the compression ratio ε of a dual-fuel engine.

Application of such fuels results in reduction of engine operation costs. The paper presents effect of application of such fuel in a turbocharged dual-fuel engine on basic operating parameters, exhaust emissions and basic combustion parameters. Test results in the form of load characteristics for various boost ratios obtained for dual-fuel engine were compared to corresponding results obtained for conventional engine operating on diesel fuel only. The obtained results indicate that it is possible a dual-fuel operation with the propane energy share of 70% for maximum engine loads.
