    Opis:
    Downsizing internal combustion engine is recognized as one of the development trends of the construction of thermal machines. Based on the design and operational factors of engines that winners are in different categories of the international competition “Engine of the Year” attempted to assess the real impact of the engine miniatu-rization. The paper discusses the idea of the competition and characterizes engines downsizing. Completing the goal of the research carried out various studies linking parameters such as torque and engine power, fuel consumption, carbon dioxide concentration and the downsizing factor. It has been demonstrated fulfilment of the downsizing idea in engineering practice and its impact on the development of the automotive industry. The study indicates that modern internal combustion engines should have a specific power with a value of more than 68 kW/dm3, specific torque factor of 127 Nm/dm3 and the volumetric emission of carbon dioxide form exhaust into the atmosphere should not exceed 83 (g/km)/dm3.

    Opis:
    Shortage of crude oil gives the reason to look for any alternative engine fuel. One of them is the hydrogen, which will be the most lean fuel between others. Knowledge of hydrogen as an engine fuel, its properties, production and storage problems were analyzed in this paper. At the end own hydrogen concept based on Fiat engine 900ccm was shown. Theoretical comparison between thermodynamic cycles for engine run on conventional petrol and hydrogen was done. Results have given the green light to future development. Petroleum recourses run out have given the reasons to find alternative fuel. One of them could be hydrogen. According to analyze done in the project it can be found similarity between hydrogen engine with 1=1,0 to petrol engine with 1=0,9. Pressure of hydrogen charge is in this case higher of 0.42 mpa and there is calculated in strength of existing engine. The results of estimation show possibility to use hydrogen as a engine fuel, maybe first as a dual-fuel engine like LPG system. Emissions of nox for hydrogen engine as well as theoretical engine work cycles for analyzed cases are illustrated in the engine.

    Opis:
    The debate on alternative fuels includes quality of combustion process depends on the properties of these fuels. The physicochemical parameters of fuel determine besides other the shape of the fuel jet, which effects on creation of mixture with air. The paper proposes a simplified method for assessing the shape of injected fuel spray based on the analysis of digital photos taken with the ordinary camera. Differences in the core of spray, jet angle and the presence of fuel droplets were presented for three different fuels. The results, described only briefly in this paper, can be helpful during the fuel injector designing or to test the engines.
    W dyskusji nad paliwami alternatywnymi przewija się zagadnienie jakości procesu spalania uzależnione od właściwości tych paliw. Parametry fizykochemiczne paliw decydują między innymi o kształcie strugi wtryskiwanego paliwa, co przenosi się na sposób tworzenia mieszaniny z powietrzem. W pracy zaproponowano uproszczoną metodę oceny kształtu strugi wtryskiwanego paliwa na podstawie analizy zdjęć wykonanych kamerą cyfrowego. Wykazano zróżnicowanie w rdzeniu strugi, kącie rozpylenia oraz obecności kropel paliwa dla trzech różnych paliw. Uzyskane wyniki, opisane tylko skrótowo w niniejszej pracy, mogą być pomocne na etapie konstruowania wtryskiwaczy lub podczas badań silnikowych.

    Opis:
    Exploitation of coal deposits is accompanied by extraction of methane, which can be a fuel for internal combustion engines. Methane with other gases states mixture with different chemical composition. It is called mine gas. Differences in the composition and the ability to lean combustion is explored in this study, where the authors have focused their attention on the selected thermodynamic parameters and operating indicators of internal combustion engine. The assessment was made on the virtual engine, which is a compilation of the actual engine, demonstrating the need for assistive technology such as charging, variable valve timing and variable compression ratio. They provide energy, despite the restrictions of the poor in the methane deposits to maintain the desired output power and reduced fuel consumption by ensuring environment-friendly operation.
    Eksploatacji złóż węgla kamiennego towarzyszy wydobywanie się metanu, który może stanowić paliwo do tłokowych silników spalinowych. Metan występuje w mieszaninie z innymi gazami i stanowi tzw. gaz kopalniany o zróżnicowanym składzie chemicznym. Różnice w składzie oraz możliwość spalania mieszanek ubogich jest przedmiotem rozważań w niniejszej pracy, gdzie autorzy skupili swoją uwagę na wybranych parametrach termodynamicznych i wskaźnikach pracy silnika spalinowego. Ocenę dokonano na wirtualnym silniku, będącym kompilacją silników rzeczywistych, wykazując konieczność stosowania technik wspomagających jak: doładowanie, zmienne fazy rozrządu czy zmienny stopień sprężania. Zapewniają one mimo ograniczeń energetycznych związanych z ubogimi w metan złożami gazu kopalnianego utrzymanie na pożądanym poziomie mocy paliwowej, a przez zmniejszone zużycie paliwa zagwarantowanie proekologicznej eksploatacji.

    Opis:
    One of the trends for development of internal combustion engine is downsizing, which in its final form leads to reduction of fuel consumption and limitation of carbon dioxide concentration in the exhaust gases. The obvious effect of reducing the volume of a cylinder is to reduce the dimensions of the various components, e.g. piston with rings and pin, connecting rod, crankshaft, engine block etc. Changes of geometric dimensions also affect the change in mass of each element and consequently − the whole engine. Expected weight reduction will be a benefit in considering downsizing techniques as another significant development trend in automotive applications associated with a reduction in the weight of the complete vehicle – called “light weight vehicle”. The paper discusses the various forms of downsizing (by stroke, by diameter and mix) and their impacts on the changes in engine mass. The engine Subaru Flat 4, constructed with standard components in terms of design and materials was tested by virtual recognition in mass changes. Original drawings of components and sets have been simplified by for example does not account for chamfers and chops. When calculating also omitted the weight of typical accessories (e.g. fuel lines or electronic components), assuming that each considered option has the same equipment. The highest change in the weight of minus 7.27 % relative to the standard engine was done with downsizing by diameter and smallest one (-6.09 %) by downsizing mix.

    Opis:
    Downsizing is one of the development trends of internal combustion engine due to its direct impact on fuel economy and indirectly in reducing the emission of carbon dioxide into the atmosphere. Changing the displacement associated with the same engine performance needs support by additional systems, which primarily include the boost. This paper describes downsizing idea, a review of recharging methods and thermodynamic analysis of the combustion process for the chosen engine before and after downsizing taking into account the different variants of boost. The core objective of this study is to downsize a naturally aspirated 1.6L BMW PSA engine by 25% of its initial swept volume and then boosting downsized engine with higher-pressure ratio using the turbocharger set. The study focuses on the analysis of four turbochargers from Garrett turbos. The study winds up with the analysis of engine performance based on the values of compression ratio, air-fuel ratio, polytropic exponents of compression and decompression with keeping the same chemical composition of the fuel. At the end, study was resulted with turbocharger Garrett GT1548 as a the best solution form considered ones, because of: wide range of pressure rate, reasonably sufficient for the engine of this size, enough room (60%) for extracting better performance, lower compression ratio value, which counts the rise of brake mean effective pressure, although to a very little extent and leaner mixture at 1,20 value of the air/fuel ratio with maximum power and reduction of fuel consumption, what was satisfied for downsizing techniques.

    Opis:
    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:
    It was found that there are discrepancies between the values of diagnostic parameters obtained in the test and natural exploitation. In addition, no appropriate tests are carried out which would be based on the degree of engine degradation in long-term natural use. One of the reasons is the lack of adequate, non-invasive diagnostic methods. The aim of the work was to show the possibility of creating a new diagnostic parameter of combustion engines in their natural operation. The parameter can be determined by a new method (presented in the article). The method is based on the assumption that the technical condition of the engine can be judged on the basis of the run-up curve, and in particular, on the basis of the linear direction coefficient, which is approximated by the points of the run-up curve at particular moments of the run-up. An additional requirement is that the points of the run-up curve are the average value of the speed from many runs. In addition, the statistical distributions of the speed values in the individual moments of the run-up should be of the same type. The direction coefficient of the straight line determined is a diagnostic parameter. The value of the new coefficient is the value of the straight-line factor. Further works are underway to determine the relationship between the directional coefficient and the technical condition of the engine.

    Opis:
    This paper touches problem of transportation pollution focusing on NOx reducing in the India. There were India country chosen for study as the second populated country and most polluted cities in the world. As from statistics, it is known that more than 65% of Indian cars are old and they are the main reason of air pollution. Most of the old cars do not have any control measures for eliminating deadliest gases. Dumping the old cars is not possible, as the poor owns most of the old cars. For eliminating the pollution from old cars, the possible remedy is to control the emission of pollutants. Comparing to all gases in exhaust, nitrogen oxides are the dangerous one. It can may cause up to death. The best method to control the NOx gas is EGR (Exhaust Gas Recirculation) valves. This research mainly focuses on the possible ways of installing EGR in old engines and fabricate an EGR in one of the Indian cars. Maruti Suzuki 800 is best of for fabricating EGR, as it is a base model and most sold Indian car. As the result, there tremendous decreasing in NOx emission also the emission CO2 was reduced. The investigation about fabricating EGR in old vehicle results a positive output after calculated the cost of the fabrication, time consumption, work challenges and other facts. As Indian government adopt this concept, they can reduce the pollution from all types of vehicles to a great extend in few years of time with low investment.

System pozwala na przeprowadzenia zarówno prostych pomiarów obejmujących liczbę pojazdów, szybkość i długość każdego z nich oraz czas pojawienia się na stanowisku pomiarowym, jak również pomiarów bardziej złożonych jak np. pomiar nacisku osi oraz masy całkowitej pojazdu poruszającego się z szybkością, nawet do 90 km/h.
    The paper describes a system designed for measurements of road traffic parameters. Its flexible structure allows tailoring the system features to current user's needs. The designed and realised system allows for measurement of different sets of traffic parameters such as number of vehicles, individual vehicle speed and length, as well as the time of passing the measurement site, up to more advanced weighing in motion. Due of compact form and alternative supply mode (230 V AC and 12 V DC), the system is fully portable. The performed field tests confirmed its usability. The uncertainty of the measured parameters corresponds to this available in commercially offered systems which usually do not allow their structure to be tailored. The innovations used in the system are: implementation of the individual vehicle speed estimation based on the magnetic signature from a single loop detector, application of a self-balancing circuit cooperating with the inductive loop detector, the axle detecting system based on the signal from a narrow (10 cm) inductive loop detector, auto-calibration procedure of the WIM system - a new, high-resolution vehicle classification algorithm.

    Opis:
    Systems of road traffic parameters measurement play a key role in the process of road traffic control, its supervision as well as in gathering and processing information for statistical purposes. Expectations of users of such systems mainly concern automation and provision of measurement continuity, possibility of selection of the measured road traffic parameters and high accuracy along with reliability of obtained results. In order to meet the requirements set for such systems, at the Department of Instrumentation and Measurement of the AGH University of Science and Technology in Cracow a new prototype system of road traffic parameters measurement - Traffic-1 - has been constructed. The innovativeness of the solution is manifested in the structure of the system that can be modified by the user adequately to current measurement needs and in the used algorithms of signals processing. The work contains a brief description of the constructed system with particular focus on the used innovations that are the result of many years of research work of the designers.
