Opis:: This article attempts at assessing the feasibility and validity of adjusting the two-stroke diesel engine to be fuelled by liquefied natural gas (LNG). It discusses a set of modifications introduced onto one of the ships carrying liquefied natural gas. These changes consisted in adjusting the engines of the main drive so that they can be fuelled by gas. This has been achieved by the modification of the cylinder head and fuel supply installation. Parameter results of the modified engines obtained during sea trials have been presented. Both advantages and disadvantages resulting from gas combustion have been pointed out. Ultimately, the authors of this article assess the applicability of this solution to other LNG carriers.

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:: 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:: Several automobile manufacturers are interested in investigating of dual fuel internal combustion engines, due to high efficiency and low emissions. Many alternative fuels have been used in dual fuel mode for IC engine, such as methane, hydrogen, and natural gas. In the present study, a reactivity controlled compression ignition (RCCI) engine using gasoline/diesel (G/D) dual fuel has been investigated. The effect of mixing gasoline with diesel fuel on combustion characteristic, engine performance and emissions has been studied. The gasoline was injected in the engine intake port, to produce a homogeneous mixture with air. The diesel fuel was injected directly to the combustion chamber during compression stroke to initiate the combustion process. A direct injection compression ignition engine has been built and simulated using ANSYS Forte professional code. The gasoline amount in the simulation varied from (50%-80%) by volume. The diesel fuel was injected to the cylinder in two stages. The model has been validated and calibrated for neat diesel fuel using available data from the literature. The results show that the heat release rate and the cylinder pressure increased when the amount of added gasoline is between 50%-60% volume of the total injected fuels, compared to the neat diesel fuel. Further addition of gasoline will have a contrary effect. In addition, the combustion duration is extended drastically when the gasoline ratio is higher than 60% which results in an incomplete combustion. The NO emission decreased drastically as the gasoline ratio increased. Moreover, addition of gasoline to the mixture increased the engine power, thermal efficiency and combustion efficiency compared to neat diesel fuel.

Opis:: Ze względów ekonomicznych i ekologicznych poszukiwane są alternatywne sposoby zasilania silników spalinowych. W silnikach o zapłonie samoczynnym, obserwuje się wzrost zainteresowania instalacjami paliwowymi pozwalającymi na domieszkę propan-butanu. Wynika to z ceny tego paliwa, szerokiej sieci dystrybucji, jak również z poprawy efektywności spalania. Wraz z rozwojem zasilania dwupaliwowego rozsądnym wydaje się być badanie wpływu dodatku LPG na emisję hałasu oraz generowanie drgań. W artykule opisano badania dotyczące zjawisk drganiowych na przykładzie silnika Volkswagena 1.4 TDI ze zmodyfikowanym układem zasilania, pozwalającym na dodawanie LPG w fazie gazowej, jak również w fazie ciekłej. Przedstawiono wyniki badań wibroakustycznych pracy silnika pod obciążeniem na hamowni podwoziowej dla różnych udziałów dawki LPG oraz dla różnych parametrów sterowania, w szczególności zmiany kąta wyprzedzenia wtrysku. Badania były próbą weryfikacji parametrów sterowania w celu uzyskania jak najniższych wartości emitowanego hałasu i drgań, przy jednoczesnym zachowaniu dużej efektywności procesu spalania. Rejestrując drgania na korpusie silnika, jak również na karoserii, oraz hałas, możliwe było wyznaczenia widma amplitudowego, na podstawie którego opracowano wnioski. Stwierdzono, jaki jest optymalny kąt wyprzedzenia wtrysku dla minimalizacji drgań oraz dla uzyskania maksymalnego momentu obrotowego.
Due to economic and ecological reasons alternative ways of supply of combustion engines are looked for. In diesel engines, a growing interest in systems allowing the admixture of propane-butane has been observed. This is due to several reasons: the price of fuel, a wide distribution network, as well as improving combustion efficiency. With the development of dual fuel engine supply, a study of the effects of LPG on noise generation and vibration seems to be reasonable, as well as an attempt to evaluate the combustion process. This paper describes the study of these phenomena on the example of the 1.4 TDI Volkswagen engine with a modified power supply allowing for the addition of LPG in the gas phase and liquid phase. The results of research on engine noise and vibration during operation under load on a chassis dynamometer for different shares of LPG and for different control parameters, in particular the injection timing,. have been presented. The study was an attempt to verify the control parameters in order to obtain the lowest possible value of noise and vibration, while maintaining the high efficiency of the combustion process. By recording vibrations off the motor housing as well as the body, it was possible to determine the noise amplitude spectrum, on the basis of which the conclusions have been formulated.

Opis:: The need to limit greenhouse gases emissions and to increase the share of renewable fuels in the general energy balance forces people to look for new alternative energy sources. Methane or biogas, in which methane is the main combustible component, is one of such fuels, which is believed to be a promising diesel engine fuel. It is worth emphasizing that biogas might be believed to be one of the cleanest fuels due to the fact that it can be produced from waste, which in normal conditions decomposes releasing methane into the atmosphere. Methane (biogas) combustion in diesel engines requires a dual-fuel feed system, in which the liquid fuel initiating auto-ignition will be injected into the combustion chamber. It comes as a consequence of a relatively high spontaneous combustion temperature of methane, which is not able to self-ignite in the chamber without an external source of ignition. This article presents a concept of constructing an integrated laboratory control system, which will provide optimal feed control of complex composition gaseous fuel and of the injection of an appropriate pilot dose of a liquid fuel into the combustion chamber. The solution proposed to control a dual-fuel diesel engine, which was mounted on the test bed, enables performing comprehensive diesel engine research, ensuring not only stable working conditions for the engine, but also granting an opportunity to smoothly regulate the composition of the artificial biogas which feeds the engine and to control basic parameters of the liquid fuel pilot dose.

Opis:: The paper presents the results of examination of particulate matter emission from the Diesel engine FPT 1.3 MJT simultaneously fuelled with diesel oil and natural gas CNG. The basic premise for engine adaptation was the addition of a small amount of CNG to reduce exhaust gas opacity and particulate matter emission. At this assumption, diesel oil remained the basic fuel, with contribution amounting to 0,70-0,85 of total energy delivered to the engine. The dual fuel engine was examined using an original controller installed in the Diesel engine FPT 1.3 MJT which controlled the diesel fuel dose. The dose of the injected natural gas was controlled by changing the opening time of gas injectors at constant pressure in the gas collector. The examined issues included the exhaust gas opacity, and the total number and fractional distribution of the emitted particles. The measurements were performed at twenty selected measuring points corresponding to the New European Driving Cycle (NEDC) test. The performed tests have demonstrated a positive effect of gas addition on exhaust gas opacity and particulate matter emission. Depending on test conditions, the exhaust gas opacity was reduced by 10÷92%, and the total number of particles by 30÷40%. The performed tests have revealed that a small addition of gas can reduce the load of the DPF filter, extend its lifetime, and increase engine reliability. Longer time intervals between successive DPF filter regenerations improve ecological properties of the engine.

Opis:: This article presents methods of acquisition of information from vehicle electronic components, with the purpose of its use to control the additional devices. These additional devices can comprise an LPG fitting, which was installed on a tested vehicle. Also, the way of modifying the contents of the engine control unit has been shown in order to examine the influence of the serial settings of the injection timing. Information that can be obtained from the CAN (Controller Area Network) allow for the lack of interference with the original manufacturer wiring, not disturbing the analogue signals at the same time. Modification of controller memory contents enables the improvement of performance parameters, especially in the case of the compression-ignition engine being fuelled with the addition of LPG. In the Summary section, the dynamometer test results of the modified vehicle have been presented. The tests were conducted for different control parameters during powering with Diesel fuel exclusively, as well as with the addition of LPG.
W artykule przedstawiono metody pozyskiwania informacji z elektronicznych podzespołów pojazdów w celu wykorzystania ich do sterowania dodatkowymi urządzeniami. Tymi dodatkowymi urządzeniami może być instalacja LPG, która została zainstalowana w badanym pojeździe. Przedstawiono również sposób modyfikacji zawartości jednostki sterującej silnika w celu zbadania wpływu seryjnych nastaw kąta wyprzedzenia wtrysku. Informacje, które można pozyskać z sieci CAN pozwalają na brak ingerencji w fabryczną instalację elektryczną, nie zakłócając tym samym sygnałów analogowych. Modyfikacja zawartości pamięci sterownika pozwala na poprawę parametrów użytkowych, zwłaszcza w przypadku zasilania silnika o zapłonie samoczynnym dodatkiem LPG. W podsumowaniu zaprezentowano wyniki badań hamownianych modyfikowanego pojazdu. Badania przeprowadzono dla różnych parametrów sterowania podczas zasilania wyłącznie olejem napędowym jak również z dodatkiem LPG.
