Opis:
More and more intensive technology development makes it possible to produce modern hydraulically driven devices which secure high reliability of operation in various conditions. To design such devices, investigations are performed, including experimental tests, which are very expensive and time consuming. In the design process of a new hydraulically driven machine or system, designers frequently have to solve problems concerning its operation in different weather conditions, for instance in low ambient temperatures. Due to the complexity of the phenomena of concern, the serviceability of the designed hydraulic component or system in those conditions is most frequently assessed based on numerical calculations, much cheaper than the experiments. The article presents three methods: experimental, analytical, and that based on computer simulation, applied for assessing the serviceability of cold hydraulic components supplied with hot working medium being a source of a so-called thermal shock.

Opis:
Designers of hydraulically driven machines and devices are obliged to ensure during design process their high service life with taking into account their operational conditions. Some of the machines may be started in low ambient temperature and even in thermal shock conditions (due to delivering hot working medium to cold components). In order to put such devices into operation appropriate investigations, including experimental ones - usually very expensive and time-consuming, are carried out. For this reason numerical calculations can be used to determine serviceability of a hydraulic component or system operating in thermal shock conditions. Application of numerical calculation methods is much less expensive in comparison to experimental ones. This paper presents a numerical calculation method which makes it possible to solve issues of heat exchange in elements of investigated hydraulic components by using finite elements method. For performing the simulations the following data are necessary: ambient temperature, oil temperature, heat transfer coefficient between oil and surfaces of elements, as well as areas of surfaces being in contact with oil. By means of computer simulation method values of clearance between cooperating elements as well as ranges of parameters of correct and incorrect operation of hydraulic components have been determined. In this paper results of computer simulation of some experimentally tested hydraulic components such as axial piston pump and proportional spool valve, are presented. The computer simulation results were compared with the experimental ones and high conformity was obtained.

Opis:
Combustion processes of liquid fuels are more complicated than gases fuels ones. With reference to liquid fuels appear additionally fuel vaporization processes and e.g. with reference to solid fuels - decomposition of the solid phase with processes melting, vaporization, pyrolysis, or gasification. Those processes demand a lot of heat, go ahead slow down than processes in gas phase. The influence of the gases pressure on combustion of liquid and solid fuels, where controlling processes are processes decomposition of these phases, is more complicated and fundamentally differs from the influence of the pressure on combustion processes of gases fuels. The influence is characterized to these that pressurization decreases the intensity decomposition both the liquid phase, and solid one. In the paper assumptions to a model of the combustion process and the model of combustion processes of liquid fuels are presented. Research of the atomization process, ignition and combustion with the using of the LDV and PDPA Doppler laser-equipment and PIV are presented in the paper. Research results of the atomized fuel spray concerning droplet diameters, research result of the atomized fuel spray concerning linear and volumetric dropletlet dispersion, Rosin-Rammler dependences, and results of the analysis of the combustion rate are presented in the paper. On combustion rate of liquid fuels, the essential influence has a kind (laminar, transient and turbulent) and the thickness of the thermal boundary layer around the fuel droplet.

Severe winters and sweltering summers which more and more often occur nowadays are the reason why machinery designers face many difficulties when designing devices which will be serviceable in extreme ambient conditions. Hence, defining the principles and conditions of safe operation of hydraulically driven machines and devices is essential for their designers and operators. For this reasons the author did a series of tests of hydraulic component and systems in thermal shock conditions (cooled-down component were supplied with hot working medium). In such conditions, starting parameters of the selected hydraulic component and systems which secured safety of their operation were determined. The experimental tests were carried out in the laboratory of the Chair of Hydraulics and Pneumatics, Gdańsk University of Technology.

Based on temperature graphs acquired from tests of heating up elements of hydraulic components it is possible to determine precisely change of clearance between cooperating elements.

Opis:
A large number of hydraulic devices and systems are started in low ambient temperatures. A good example of such a device is the hoisting winch on the ship. Starting hydraulic drive units in thermal shock conditions (rapid supply of hot oil to the cold unit) may lead to incorrect operation of the actuating system, for instance, due to the loss of clearance between cooperating elements. The article presents methods to prevent the disappearance of effective clearance in a hydraulic motor started in thermal shock conditions. For this reason, the structure of the hydraulic satellite motor was complemented by elements creating special channels through which hot oil could flow and additionally heat fixed parts of the motor. This solution ensures faster heating of motor housing, thus decreasing the temperature difference between the housing and the satellites during motor start-up in thermal shock conditions.

Opis:
The increasing use of petroleum derivatives as a result of industrial development and urbanization has a negative impact on the natural environment. Due to their toxic and carcinogenic effects, these compounds have a negative impact on living organisms and plants, and also contribute to changes in soil properties and composition, and the abundance of microorganisms present in this soil. Sources of pollution with petroleum derivatives to the soil environment are mostly refinery and petrochemical plants, crude oil extraction sites, storage and distribution sites for petroleum products, transport of crude oil, and traffic accidents. Remediation of an area polluted with petroleum derivatives can be done by their decomposition, transformation into less toxic reactive and mobile forms, or by total elimination. Chemical, physical and biological methods are used for this purpose. In the biological methods, the most important role is played by microorganisms capable of using hydrocarbons as a source of carbon and energy.
Wzrost wykorzystania związków ropopochodnych na skutek rozwoju przemysłu i urbanizacji wpływa negatywnie na środowisko przyrodnicze. Związki te ze względu na właściwości toksyczne i kancerogenne wykazują negatywny wpływ na żywe organizmy, rośliny, a także przyczyniają się do zmiany właściwości i składu gleby oraz liczebności obecnych tam mikroorganizmów. Źródłami skażenia związkami ropopochodnymi środowiska gruntowego najczęściej są: zakłady rafineryjne i petrochemiczne, miejsca wydobywania ropy naftowej, miejsca magazynowania i dystrybucji produktów ropopochodnych, transport ropy naftowej, kolizje drogowe. Remediację terenu zanieczyszczonego związkami ropopochodnymi można dokonać poprzez ich rozkład, przekształcenie w formy mniej toksyczne, reaktywne, mobilne lub całkowitą ich eliminację. W tym celu wykorzystywane są metody chemiczne, fizyczne oraz biologiczne. W metodach biologicznych największą rolę odgrywają mikroorganizmy zdolne do wykorzystania węglowodorów w charakterze źródła węgla i energii.

Opis:
Emissions from aircraft engines represent a highly complex and important issue, which is related to the risk to human health. Particles emitted in urban areas and in the vicinity of airports affect air quality and have a particularly negative impact on airport workers. The development of measurement techniques and the methodology for evaluating exhaust emissions have allowed for the elaboration of appropriate procedures for the certification of aircraft and the enhancement of existing standards. Particulate matter emissions depend, among other things, on the composition of the fuel used and its additives. Some aircraft engine designs require a fuel additive in the form of oil, which ensures the proper operation of the fuel supply system. This article presents the results of studies conducted on jet engines powered by clean aviation fuel and fuel with the addition of oil. The aim of the study was to evaluate the effect of the addition of oil on the size distribution and concentration of emitted particles. It was found that, for small values of thrust, oil additive increases the concentration of particles. With an increase in the thrust force, the reduction of particles concentration was recorded in the case of the engine powered by fuel with oil additive. There was no significant effect of oil additive on the size distribution of emitted particles.

Opis:
Air transport is the youngest and most dynamically developing branch of transport. Growth in demand for air transport, both passenger and freight, is caused by the competitiveness of this branch primarily in terms of time and transport safety. An increase in the volume of air traffic is associated with increased emissions, which is particularly important in the case of aircraft operations in the areas of airports. The main reason for the development of aircraft engines is the reduction of fuel consumption and exhaust emissions. Emission standards for aircraft engines certification marginally treat the issue of particulate matter emissions, which is associated with deterioration of visibility appearing as smog and contributes to lung and heart diseases. One of the solutions for limiting the negative impact of the aircraft on the environment is the use of alternative fuels. Production of biofuels in accordance with the principles of sustainable development, is an attractive alternative, especially because of the lack of space constraints of their production allows the geographical diversification of supply. The article presents the measurements results of jet engine GTM-120 exhaust emissions. The test engine was powered with Jet A-1 fuel with 50-percent addition of bioester. During the test concentration of carbon monoxide, hydrocarbons and particulate matter was measured. On the basis of the measurements, the effect of the use of biofuel on emissions was presented.
Transport lotniczy jest najmłodszą i najbardziej dynamicznie rozwijająca się gałęzią transportu. Wzrost zapotrzebowania na przewozy drogą lotniczą, zarówno pasażerskie i towarowe wynika głównie z krótkiego czasu transportu oraz bezpieczeństwa. Wzrost wolumenu transportowego związany jest ze wzrostem emisji związków szkodliwych spalin, co jest szczególnie istotne w kontekście emisji na terenie lotnisk oraz obszarach do nich przyległych. Głównym celem rozwoju konstrukcji silników lotniczych jest zmniejszenie zużycia paliwa i redukcja emisji związków toksycznych. Procedury certyfikacyjne dla silników odrzutowych marginalnie traktują zagadnienie cząstek stałych, które są powodem pogorszenia widzialności oraz chorób płuc i serca. Jednym z rozwiązań ograniczających wpływ transportu lotniczego na środowisko jest stosowanie paliw alternatywnych. W artykule przedstawiono wyniki pomiarów emisji związków szkodliwych silnia odrzutowego GTM-120. Badany silni zasilany był paliwem Jet A-1 oraz mieszanką nafty lotniczej z biopaliwem. Podczas badań zmierzono wartości stężenia tlenku węgla, węglowodorów oraz cząstek stałych. Na podstawie przeprowadzonych badań przedstawiono wpływ zastosowania biopaliwa na emisję związków szkodliwych.

Opis:
New test procedures for determining exhaust emission from passenger vehicles will be introduced in 2017. For several years, the European Commission has been developing new procedures, which aim is to perform tests in road conditions. The purpose is to determine the real values of emissions, which are not always reflected by the level of emissions obtained in the laboratory. Proper and accurate procedures for determining emissions in real traffic conditions (RDE – Real Driving Emission) have not yet been approved (as opposed to Heavy Duty Vehicles for which such conditions already exist), but there are proposals that are currently being analyzed by major research centers in Europe. There are many differences between those proposals such as determining road emission or research methodology related to emission measurement of hydrocarbons. The work compares the results of emissions measured in road tests using the latest legislative proposals related to passenger cars. The results are shown in relation to the used measurement method: classic method of determining exhaust emission; uses all measurement data determining the mass of harmful compounds and distance travelled during the test; method of averaging the measuring windows (MAW – moving average windows), also in the literature called EMROAD method, which determines the measurement windows (on the basis of carbon dioxide emissions from the WLTC test) and on its basis determines the road emission in RDE test; generalized method of instantaneous power (Power Binning), known in the literature as CLEAR – Classification of Emissions from Automobiles in Real driving, determines road emissions on the basis of generalized instantaneous power during the RDE test.

Opis:
At the beginning of the twenty-first century, one of the major challenges of humanity was to reduce the negative effects of civilization development. Besides the engines used in road vehicles there is a large group of engines for non-road applications. This group includes motor propelled vehicles not used on the road NRMM (Non-Road Mobile Machinery). Engines of these vehicles, among all of the non-road applications, are characterized by very specific working conditions that do not allow them to be qualified for propulsion engines. The main problem with these vehicles is the particulate matter and nitrogen oxides emission. The paper presents an analysis of the operating parameters of an engine and exhaust emissions of a tractor operating on a chassis dynamometer. Studies of the tractor involved measurements of engine operating parameters and the concentration of harmful substances in the exhaust gases. Information about the parameters of the engine and the intensity of emissions were obtained during the dynamometer test. The study included a comparative analysis of the operating parameters of the engine obtained from the diagnostic system and direct measurements on a chassis dynamometer and a correction of the torque obtained from the vehicle computer system was made. As a result, values of specific emission during engine tests under varying values of load were determined.

The article concerns the evaluation of exhaust emissions from turbine engines. The results of the work are associated with development of analytical methods useful in estimating the emissions of harmful exhaust gases during turbine engine operating conditions. The results of studies and the interdependence between emission indicators and operating parameters were pointed out. The analysis of these interdependence shows a strong similarity in the nature of changes of particular relationship in relation to the engines tested, but also shows their individuality. The article shows the direction of further work to develop methods of assessment the emissions from turbine engines during their operation. The methods developed for the analysis of ecological parameters during operation of turbine engines may be useful to implement in models of assessing pollutant emissions from maritime transport and to analyze and evaluate the impact of transport on the environment. This assessment may be important to consider, with regards to meeting the newly introduced emission standards, in accordance with the MARPOL directive, which has been in force since January of 2015.
