Opis:
The article addresses the topic of carbon dioxide emissions into the atmosphere as the result of the hydrocarbon fuels combustion in the combustion engines. Widespread use of individual means of transportation, where the combustion engines function as the basic propulsion source, has caused that they are one of the main sources of carbon dioxide emission into the atmosphere. Therefore, it has been subjected to some restrictions, similar to those applied towards toxic elements contained with exhaust. One of the most effective ways of restriction of carbon dioxide emission is to decrease fuel consumption. In addition, an important item is the implementation of fuels with less potential to create carbon dioxide as a result of their combustion. The article presents the results of comparative measurements conducted on the engine test stand in terms of prepared load characteristics for a spark ignition engine powered by gasoline as well as by natural gas. On the basis of these measurements the article provides the analysis of the impact of fuel composition and combustible mixture on carbon dioxide content in the exhaust gases. In the next stage of analysis, the criterion for the comparison was the value of carbon dioxide emission with reference to 1 kg of fuel resulting from the measurements and theoretical calculations of fuel combustion. The results of measurements and calculations were shown in forms of graphs. The measurements on a test stand were conducted for the engine of the older generation, whose design corresponds to the motors located in a large number of currently used vehicles. This allows a preliminary estimation of the carbon dioxide emissions coming from means of transport.

Opis:
The types and action mechanism of depressant additions, which improves the properties of diesel fuels in low temperatures, were presented. The results of a sixteen different depressants influence on cloud point (CP) and cold filter plugging point (CFPP) of diesel fuels ONA without additions are given in following elaborate. The depressants were applied to samples of diesel fuel in concentration between 500 and 5000 ppm. The present paper shows correlation of diesel fuels ONA CFPP and ΔCFPP depression between depressants concentration. Only a part from the tested depressant additions has a significant impact on diesel fuel cloud filter plugging point at concentration recommended by their manufacturers. Moreover, some of the additions do not decrease the CFPP value. The depressants can be divided into three groups by their effectiveness: first, the ones which decreases greatly the CFPP (from 3 to 11 degrees) by adding only small amount of them (500 ppm), second, with almost no influence on CFPP values in smaller amounts (500 ppm) but reducing CFPP values in larger quantities (to 5000 ppm), third, with no influence on diesel fuels ONA CFPP even in large concentration. In conclusion, lowering the CFPP value depends on the kind of depressant and its concentration in diesel fuel and not on the diesel hydrocarbon composition with addition up to 7% of Fatty Acid Methyl Ester (FAME).

Opis:
Currently produced internal combustion engines used in transportation, must meet very stringent legislative requirements EURO VI, for the limited emissions of exhaust gases: CO, HC, NOx, PM, PN. One of the most toxic components and the most difficult to eliminate are nitrogen oxides NOx, which currently permissible amount in the exhaust gases shall be 80 mg/km. This result must be achieved, moreover, with the fulfilment of the limits for other exhaust components, and above all, the contents of particulate matter (PM, PN). It should be pointed out, that the mechanisms of the NOx and PM formation are opposed to each other; reduction of the NOx amount is generally associated with an increase in PM and vice versa. Therefore, issues of lowering the amount of NOx in the exhaust gases devote a lot of scientific work and engine research. Currently the most effective method of reducing the NOx is the selective catalytic reduction (SCR), which requires the additional installation of sophisticated equipment in the vehicle. Therefore, methods easier to implement and to operate are sought. One such method is the use of a microemulsion to supply as fuel to diesel engines, consisting of an emulsion of diesel oil, water and surfactant (surface-active compound). The use of the microemulsion results in that already in combustion chamber forms less of NOx, and therefore reduction of NOx in the exhaust system is easier. The publication presents results of SB 3.1 engine research on the engine test bench. The research was comparative in nature and thus, in the first stage of research conducted, the engine was fuelled with diesel oil, then the area of engine load and engine speed characteristics, in which the NOx emissions are greatest, was determined, and next, when engine was fuelled with various microemulsions, the engine investigation was conducted in this area. The microemulsions of diesel fuel and water comprise 10%, 20% and 30% water, selectively. The results of investigations show that, when the engine is fuelled with microemulsions, both NOx and PM, as the main component of diesel engine exhaust - soot (smoke) can be reduced at the same time. The article also discusses the differences between emulsions and microemulsions, and how they influence the combustion in the engine combustion chambers.

Opis:
Increasingly higher demands pnt on piston internal combustion engines arę aimed at reducing their harmful impact on the natural environment. This refers primarily to nitrogen oxides, particulate matter and noise emissions. The reduction in emissions ofnoxious components oj exhaust gases in engines is achieved by means of, among others, the use of catalysts decreasing nitrogen oxide emissions, particulate matter filters and oxidising catalysts decreasing carbon monoxide and hydrocarbon emissions. Common Rail injection systems make it possible to increase the engine power, and to reduce fuel consumption, exhaust gas toxicity and noise produced by engines. With Common Rail systems, the pattern of fuel injection process can be designed, consequently the combustion process can be controlled. The paper presents the results of test bench investigations into a compression ignition 1.3 Multijet engine with multistage fuel injection, which is manufactured in Poland by Fiat-GM Powertrain Polska Company. The tests were conducted at a stand constructed at the Heat Engines Laboratory ofthe Kielce University of Technology. The scope of investigations included determining economic and energetic parameters of the engine work, and also environmental parameters, such as the concentration of nitrogen oxides NOX, carbon monoxide CO and carbon dioxide CO2 in exhaust gases, and exhaust gas smokiness. In tests, the engine operated under speed conditions and it was fuelled by two commercial diesel oils that had different physical and chemical properties.

Opis:
The contemporary progress of automotive industry and transportation is determined to a large extent by the increasing environmental requirements, aimed at limiting the harmful impact of vehicles upon human life and people’s health. A crucial issue linked with operating vehicles is the exhaust gases generated by internal combustion engines. In order to reduce this hazardous impact upon the natural environment, the construction of the engines is continuously improved, electronic controlling is being developed for managing the course of working processes taking place in cylinders and auxiliary systems, exhaust gases cleaning systems are being developed, alternative fuels are being sought for and the possibilities of their optimal use are being examined. Natural gas is the fuel that is highly expected and hoped to be used more widely for powering internal combustion engines in vehicles. This article presents the values of selected ecological indicators of the Perkins 1104D-E44TA Diesel engine, powered by compressed natural gas and Diesel fuel (CNG + ON). For comparison reasons, the engine was powered with both fuels at the same time and then only by Diesel fuel (ON) in the same working conditions. Before the tests, the powering system control unit had been calibrated so as to enable obtaining similar values of torque while the engine was powered with the Diesel fuel only and with both CNG and ON while working with external speed characteristics; the calibration was also set up to allow for the maximum share of the natural gas in the total fuel amount supplied into the engine cylinders without engine knocking. When powering the engine with both CNG and Diesel fuel, the concentration levels of nitric oxides and carbon dioxide in exhaust gases were lower. However, the total content of hydrocarbons in the exhaust gases grew multiple times, and the content of the carbon monoxide was significantly increased. In addition, the obtained measurement results of the smokiness of the exhaust gases and the content of the soot with the engine powered with two fuels were not satisfactory.

Opis:
Increasingly strict standards for exhaust emissions in piston combustion engines force manufacturers and users to seek and apply different means to meet those standards. The effect of the type of fuel on the pattern of engine fast-changing quantities such as the pressure of the working medium in the cylinder, fuel pressure in the injection pipe and the injector needle lift is discussed in the paper. In test bench investigations, the self-ignition engine of AD3.152 UR type operated in the load characteristics regime for the crankshaft rotational speeds 1400 and 2000 rpm and was fuelled by Ekodiesel Ultra D diesel oil (DO), rapeseed oil fatty acid methyl esters FAME and blends of the two fuels, which had 20% and 30% ester content, i.e. B20 and B30. Based on fast-changing quantities diagrams obtained, selected parameters of fuel injection and combustion processes in the engine under consideration were computed. It is shown in the paper that fuel injection and combustion start in the engine fuelled by rapeseed oil fatty acid methyl esters FAME or blends B20 and B30 occur a little earlier than when it is fuelled by diesel oil. When the engine operating in the load characteristics regime is fuelled by FAME or blends with diesel oil, slightly higher values of the maximum pressure in the cylinder and fuel pressure in the injection pipe are obtained. It is demonstrated that in the engine fuelled by FAME or B20 and B30, the injection advance angle should be slightly delayed in comparison with the manufacturer's setting for the engine fuelled by diesel oil.
Wprowadzanie dla tłokowych silników spalinowych coraz bardziej rygorystycznych norm emisji spalin, wymusza na ich producentach i użytkownikach poszukiwanie i stosowanie różnych środków zapewniających spełnienie tych norm. W artykule przedstawiono wypływ rodzaju paliwa na przebiegi wielkości szybkozmiennych silnika takich jak: ciśnienia czynnika roboczego w cylindrze, ciśnienia paliwa w przewodzie wtryskowym i wzniosu iglicy wtryskiwacza. Podczas badań hamownianych silnik o zapłonie samoczynnym typu AD3.152 UR pracował według charakterystyk obciążeniowych przy prędkościach obrotowych wału korbowego 1400 i 2000 obr/min i zasilany był olejem napędowym Ekodiesel Ultra D (ON), estrami metylowymi kwasów tłuszczowych oleju rzepakowego FAME i mieszaninami tych paliw o zawartości estrów 20% i 30%, tj. B20 i B30. Na podstawie wyznaczonych przebiegów wielkości szybkozmiennych obliczono wybrane parametry procesu wtrysku paliwa i procesu spalania w badanym silniku. W pracy wykazano, że wtrysk paliwa i początek spalania, w przypadku zasilania silnika estrami metylowymi oleju rzepakowego FAME i paliwami B20 oraz B30, następował nieznacznie wcześniej niż w przypadku zasilania go olejem napędowym. Zasilając silnik pracujący według charakterystyk obciążeniowych, estrami FAME oraz ich mieszaninami z olejem napędowym, uzyskiwano nieznacznie większe maksymalne wartości ciśnienia w cylindrze oraz ciśnienia paliwa w przewodzie wtryskowym. Wykazano, że przy zasilaniu silnika paliwem FAME oraz paliwami B20 i B30, należy nieznacznie opóźnić kąt wyprzedzenia wtrysku paliwa w stosunku do ustawienia fabrycznego, określonego przy zasilaniu silnika olejem napędowym.

It is oblivious, various properties of fuels cause different thermal loads of engines. Question is, how big is this effect and what fuel compound and its property play insignificant part. This paper is focused on problem of quality of diesel commercial fuels in Polish market and it is a challenge to find answer for question mentioned above. The academic staff from Wroclaw University of Technology organized tests with different commercial fuels. Chemical and physical properties of these fuels were studied and used for investigation to define relationships between them and thermal load during simulation process. All researches were done in the lab of Division of Motor Vehicles and Internal Combustion Engines at the Wroclaw University of Technology. Tests have showed differences in chemical and physical properties of fuels, but there is no statistics effect on engine parameters. Results have not also pointed any important differences in thermal loads of engine VW1,9 TDI and its components according to different physical and chemical properties of tested fuels. It is probably because there are differences of calorific values from one side but from other hands various density and specific fuel consumption compensated these differences. To burn unit of fuel contains higher level of oxygen, engine needs lower amount of air, so it gives, for the same fuelling system, lean mixture. It causes higher temperature of exhaust gases and a bit higher exhaust losses

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:
Term “jet fuel” is well known and recognized worldwide - it applies to aviation product used to power all turbine engines in aircrafts and helicopters. Its’ properties are clearly and strictly defined in international specifications. However, in the discussion concerning jet fuels, and in most research material, many people seem to forget that this fuel is a mixture of different hydrocarbons, is produced from different feedstock (crude oil from different sources available worldwide) and as a final product is obtained with different production processes. Thus, however jet fuel must meet the requirements defined in international standards, these fuels differ each other and as a result, differences can be observed in logistic chain and in combustion process. This paper points out some differences between jet fuels and its aim is to convict users, researchers and all people in aviation industry dealing with jet engines operation, that - when talking about jet fuel - many factors and details about final product must be considered, and this type of product should not be seen as single-type fuel, as most people see it now. The article has been prepared within the research project funded by the National Science Centre in Poland and granted with decision no. DEC-2011/01/D/ST8/06567.

Opis:
The paper presents results of examinations concerning stream spray and ignition delay angles of AD3.152 engine fuelled with mineral fuel Ekodiesel Plus 50B and comparatively fuelled with vegetable fuels like methyl ester FAME and ethyl ester FAEE. Using fuels of different physicochemical properties to diesel engines requires high accuracy of diagnostic parameters measurements in order to learn differences in processes of injection and combustion. Necessity of fulfilling more and more strong standards, concerning emission of toxic components of exhaust gases, forces users of diesel engines to posses quick and precision methods of their technical state assessment and particularly of a combustion process and of injection equipment technical state. Analysis of the obtained diagrams of fuel pressure in the injection pipe enables to determine fuel pressure increase rate. The investigations were carried out on the basis of speed external characteristic using test stand equipped with system of quick-changeable pressures measurements. Stream spray of fuel and ignition delay angles influence combustion process what is connected with emission of toxic components to environment. However, decay period time tested fuels and their limits appeared smaller for vegetable fuels. Considering the results, it is therefore decide to continue our experiments.

Opis:
The development of motorisation involves using bigger amounts of fuels. These fuels are, until now, mainly petroleum. However, the fuels of bio origin must be used as well. It follows from the necessity of ensuring CO2 balance and from the fact that oil sources sooner or later will become exploited. Not less important is the fact that, principally, it is difficult to change the proportions of petrol and diesel oil extracted from crude oil, and the use of diesel oil increases proportionally faster than petrol. Therefore, it is necessary to use bio additives in diesel oil. One of such additives is dense alcohols. The aim of the present work is to determine the energy balance of diesel engine powered by diesel oil and butanol mixture. The work field includes making of energy balance of the engine in its characteristic points responsive 13 phase ESC test as well as determining on this basis the consolidated values concerning the differences in the engine energy balance. It has been proved, that powering the engine by mineral diesel oil with doped butanol (20% v/v) does not lead to essential differences in the energy balance of the engine- which does not mean, that the essential differences are absent in the particular characteristic points of the engine. It requires more detailed explanation (in the further research works) because losses in the combustion process do not show differences, but in the other balance components the differences are shown.
