Opis:: The experiments described in the article aimed at adjusting the engine test bed, its equipment and software to perform comprehensive tests on a dual-fuel spontaneous combustion engine with the main gas dose (methane or biogas) and a liquid fuel ignition dose. The steps undertook during the tests included installing a new engine on the engine test bed, installing its equipment and preparing a dual-fuel feed system. The toxic emissions analysis system was also modified, thanks to which a thorough research based on current test methods was possible. All measurement devices were integrated and are governed by one system of data acquisition and controlling, which ensures repeatable testing conditions. In order to exercise better control over the oil pilot dose injection, the previously used engine was replaced with a Common Rail one, which facilitates better control over the pilot dose injection and ensures controlling the system through an external driver. Providing the engine with a set of measurement systems makes it possible to test it not only with reference to its power and toxic emissions into the atmosphere, but also to the heat absorbed by the cooling system, which enables testing engines for cogeneration units.

Opis:: Biodiesel is widely perceived as a source of ecological energy used to power compression ignition engines as an alternative to fossil fuels. Depletion of fossil fuels and increasing environmental awareness of society has led to an increased demand for energy derived from renewable sources. This phenomenon requires acquisition of raw material used for biofuel production. In order avoid controversies related to misuse of edibles; sources of biofuel production should be viewed as inedible or waste materials. This paper presents an analysis of possible sources of animal material intended for biofuel production. An examination of the quality assessment for biofuels obtained in the laboratory setup, produced from swine lard and turkey fat is presented. The results have been compared to rapeseed biofuel and commercial diesel fuel as fuels commonly used to power compression ignition engines. The paper concerns an examination of pure biofuels and their mixtures with commercial diesel fuel in three different proportions. Parameters such as density, viscosity, acid value, cold filter plugging point, oxidation stability, sulphur content, total contamination, water content and flash point has been examined according to procedures outlined in the PN-EN 14214 Standard. Based on the results, biofuels and their mixtures have been analysed for use in compression ignition engines.

Opis:: The struggle against global warming necessitates the search for new sources of energy, which limit the emission of carbon dioxide into the atmosphere. Among various fuels used to supply energy nowadays, the importance of natural gas is constantly growing. This is caused by the fact that this fuel is characterised by the lowest share of coal among all fossil fuels. Because of its properties, natural gas can be used directly to power spark-ignition engines. The use of this fuel for compression-ignition engines on the other hand is limited due to the high autoignition temperature of methane. Currently, research is being conducted in numerous centres on the possibility of using fuel gases to power CI engines operating in a dual-fuel system. The present article discusses the impact of the share of CNG in the supply dose on the operation of a CI engine. An engine with the Common Rail injection system programmed for mono-fuel operation was used in the research. Based on the conducted tests it has been proved that supplying this type of engine with fuel gas considerably changes the course of the combustion process, which is caused by the fact that the gas and air mixture present in the combustion chamber starts burning now of the autoignition of the first portion of liquid fuel. The obtained test results confirm the necessity to change the injection parameters of the pilot dose of diesel fuel (the timing angle of injection and the pressure of fuel) in cases when this type of engine operates in a dual-fuel system.

Opis:: Vision of depletion of fossil fuels and associated with the usage negative impact on the environment, resulted in increased interest in finding alternative sources of materials, which may be used to power internal combustion engines. Usage of biofuels to power diesel engines offers a wide range of benefits for the user and also the environment. Biodiesel interpreted as fatty acid methyl esters obtained from renewable resources by transesterification of fatty acids, can be used as an alternative fuel to petro-diesel, as well as pure fuel or as an additive to diesel. Due to its “renewable” origin and characteristics, such as biodegradability or lower emissions of toxic components in the exhaust gases, biodiesel is a highly attractive alternative to fossil fuels. Although it is possible to feed CI engines with pure biodiesel, many researchers points lot of, operational and related to combustion processes, problems with usage 100% biodiesel in modern engines, equipped with technologically advanced injection systems. In order to maintain best performance properties, a number of standards have been made. These standards clearly define the parameters that biodiesel must met to be used for powering CI engines. This paper presents comprehensive analysis of properties of pure biodiesel and its mixtures with diesel in terms of usage to feed modern CI engines. Also procedure of obtaining biodiesel, laboratory equipment and procedures were presented. A number of key parameters (density, viscosity, acid value, cold filter plugging point, oxidation stability, sulphur content and flash point) were examined for pure biodiesel and its mixtures. Tests were performed according to procedures outlined in the PN-EN 14214. Based on the results the utility of biofuels and their mixtures was presumed for use in compression ignition engines.

Opis:: The use of renewable fuels can reduce consumption of fossil fuels as well as diversify the range of alternative energy carriers. The advantage of biofuels is that they can be obtained from waste materials. Biofuels derived from vegetable or animal raw fatty material, as a result of transesterification, are characterized by similar physicochemical properties to mineral diesel fuel in terms of quality standards, however the fatty acid composition of the raw material can significantly influence exhaust gas emissions. The aim of the research is to determine the impact of the origin of various renewable biocomponents on exhaust gasses concentration emitted by compression ignition engine. The tests were conducted on a Common Rail, direct injection engine, operating under steady state conditions. Two kinds of biofuels produced from different fatty raw materials (rapeseed oil and swine lard) were used. All the experiments were performed on fuels containing a total of 50% biocomponent shares admixed to commercial diesel fuel. The tested samples included both: binary and ternary mixtures. During the experiments the differences in: hydrocarbons, carbon monoxide and nitrogen oxides concentrations were examined as a result of different fuel composition. The study shows that the best results were achieved for fuel containing both plant and animal biocomponents.

Opis:: The use of liquid fuels as an energy source for internal combustion engines is unavoidable nowadays, further consumption increases with the development of industry and economic growth of the country. The abundance of the world in fossil fuels is a highly controversial issue; however, irrespective of forecasts concerning deposits of mineral fuels, undisputable fact is that these are resources, which will deplete. Economic, environmental and legislative issues also impose a limitation of use of fossil fuels. Under the problems associated with fossil fuels, an interesting alternative may be fuel derived from renewable sources. Biodiesel understood as a renewable energy source, used to feed compression ignition engines seem to be the ideal solution to meet energy needs, facing so called economic circulation era. Many research results confirm that combustion of pure biofuels in the currently highly advanced injection systems causes many problems. Different biofuel properties from diesel, such as viscosity or density directly influences on combustion process and emission of toxic components in the exhaust gases. Therefore, biodiesel blends with diesel fuel in all proportions; the combustion of such mixtures carries a number of benefits, from consumption reduction of non-renewable resources to reduction of harmful components in the exhaust gases. In this paper, the effect of doping methyl esters on the process of combustion and exhaust gases emissions in a compression ignition engine feed with mixtures of esters and diesel was examined. Tests were performed on four-cylinder, CI Andoria ACDR engine equipped with Common Rail fuel injection system. In order to investigate the combustion process, cylinder pressure and toxic components in exhaust gases steady state measurements were performed.

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.

Omówiono różne rozwiązania konstrukcyjne silników o zasilaniu dwupaliwowym. Przedstawiono wpływ parametrów decydujących o spalaniu różnych paliw w silniku dwupaliwowym. Opisano sposób adaptacji silnika 1.9 TDI do zasilania dawką pilotującą (ester etylowy wyższych kwasów tłuszczowych) i wtryskiwanym pośrednio metanem. Omówiono specyficzne procedury sterowania silnika zasilanego dwoma paliwami, zwracając szczególną uwagę na współpracę oryginalnego sterownika pompy wtryskowej z opracowanym przez autorów sterownikiem ilości metanu. Przedstawiono porównawcze wyniki badań hamownianych tego silnika. Badania zrealizowano przy wykorzystaniu zautomatyzowanej hamowni silnikowej AVL z systemem PUMA. Wskazano, że zasilanie dwupaliwowe jest korzystniejsze niż zasilanie silnika olejem napędowym ze względu na niższą emisję związków szkodliwych, szczególnie w zakresie zadymienia spalin i poziomu dwutlenku węgla. Badania te wykazały także konieczność precyzyjnego sterowania kątem wyprzedzenia wtrysku dawki pilotującej ze względu na pojawiające się problemy z nadmierną emisją hałasu związanego ze spalaniem i podniesieniem temperatury mediów szczególnie w zakresie obciążeń nominalnych. Wyniki tych badań mogą stanowić wskazówkę do dalszych prac w zakresie realizacji metod zasilania silników o ZS paliwami gazowymi 2-generacji pochodzącymi ze zgazowania lub pirolizy biomasy organicznej.
