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:: Biogas is among the fuels whose significance in the general energy balance will increase. These results from the fact that it may be produced from various kinds of waste materials, and it is therefore considered a renewable fuel of the second generation. Because of its properties, biogas may be used directly to power spark-ignition engines. Nonetheless, numerous tests are underway involving the possibility of using biogas to power compression-ignition engines. In order to use biogas, whose main combustible component is methane, in compression-ignition engines, it is necessary to use a dual fuel power supply system. With such a system supplying power to the engine, the gas and air mixture in the cylinder is ignited by a small dose of liquid fuel. This paper presents a fragment of the research on the use of biogas with a varying chemical composition for powering compression-ignition engines. The described tests were conducted using a one-cylinder compressionignition engine mounted on an engine test stand. The fuel gas consisted of a mixture of natural gas and carbon dioxide; the share of each individual component was regulated from the station, which controlled the operation of the whole test stand. The developed control system also enabled the adjustment of the operating parameters of the engine test stand and the parameters of the injection of liquid fuel, such as the injection pressure, the timing angle of injection and the size of the dose. The results presented in the paper show the impact of the individual control parameters of the engine on the value of the engine’s torque and the amount of toxic compounds in the exhaust fumes.

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.

Tytuł:: The concept of an integrated laboratory control system for a dual - fuel diesel engine

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 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:: Seeking alternative sources of energy for its more effective use, reducing emissions of toxic pollutants to the atmosphere and counteracting global warming are nowadays the major areas of development in the power industry, including the design of combustion engines. Currently, the research into the use of new fuels, which may be effective sources of energy, is performed by many scientific centres. The use of biogas for production of energy in cogeneration systems is one of the ways for improvement of energy balance. In the research described herein, a dual-fuel compression ignition engine was fuelled with gaseous fuel with variable CNG and CO₂ ratios. The tests were performed for engine fuelling controlled by both an original controller with the software optimised for single-fuel operation and for the injection of a pilot dose of diesel controlled by a dedicated controller enabling the adjustment and control of the injection and dose parameters. This paper presents the effect of carbon dioxide content in gaseous fuel on the combustion process and emission of toxic compounds in the engine examined.
Poszukiwanie alternatywnych źródeł energii, zwiększenie efektywności jej wykorzystania, a także zmniejszenie emisji związków toksycznych do atmosfery i walka z globalnym ociepleniem są głównymi współczesnymi kierunkami rozwoju przemysłu energetycznego, w tym również silników spalinowych. Obecnie w wielu ośrodkach naukowych prowadzone są badania nad wykorzystaniem nowych paliw, które mogą być efektywnym źródłem energii. Jednym ze sposobów poprawy bilansu energetycznego jest wykorzystanie biogazu do wytwarzania energii w układach kogeneracyjnych. W opisanych w artykule badaniach dwupaliwowy silnik o zapłonie samoczynnym zasilany był paliwem gazowym o zmiennych proporcjach CNG i dwutlenku węgla. Badania przeprowadzono przy sterowaniu zasilaniem silnika zarówno przez oryginalny sterownik oprogramowany do pracy jednopaliwowej, jak i przy sterowaniu wtryskiem dawki pilotującej oleju napędowego przez dedykowany sterownik umożliwiający regulację i kontrolę parametrów wtrysku tej dawki. W artykule przedstawiono wpływ zawartości dwutlenku węgla w paliwie gazowym na przebieg procesu spalania oraz emisję związków toksycznych badanego silnika.
