Opis:: The article’s aim was to compare an ecological effectiveness of a common jetliner with 189 passenger capacity flying on two CFM engines and a very light jet business aircraft designed to carry up to 8 people on board. The carried-out analysis showed that the NO_x emission per passenger in Very Light Jet (VLJ) is three times higher than in common jet airliner, furthermore there is 15 times difference in CO emission. Based on the results of the analysis, it can be stated that it is appropriate to extend the certification of engines to smaller units, as well as to adjust the LTO test beyond laboratory conditions.

Opis:: Although perceived as the most environmentally friendly means of transport, ships are a significant source of pollution to the environment. The vast majority of emissions in EU sea areas are emitted from cargo ships over 500 GT. About 45% of all emissions come from EU flagged ships and approximately 20% of emissions are emitted within the 12-mile limit of territorial seas. In port cities, ship emissions are in many cases a dominant source of pollution and need to be addressed when considering compliance with legally binding air quality objectives. Moreover, emissions from ships travel over hundreds of kilometres and can thus contribute to air quality problems on land even if they are emitted at sea. This is particularly relevant for the deposition of sulphur and nitrogen compounds, which cause acidification of natural ecosystems and threaten biodiversity through excessive nitrogen inputs. Emission of toxic compounds in marine engines exhausts is limited by international legal provisions, namely MARPOL convention, which in Annex VI sets limits to SOx and NOx emissions and designates special areas where the limits are stringent. To comply with the provisions, marine vessels need to be equipped with installations reducing emissions to permissible levels or turn to alternative fuels. The paper presents evaluation of impact of those having been in force for the last decade limitations as well as of applied new technological solutions on improvement of air quality. The analysis was conducted for the Baltic Sea, based on available data on ship traffic in the area and emission factors.

Opis:: Among the most important problems faced by the air transport today there can be mentioned some negative influences of aircraft and airports on the environment and the increasing costs of air transport. One of the possibilities to improve the situation is to work out innovative solutions aimed at decreasing of the aircraft pollution and improving the transport effectiveness. Among the most innovative ideas is the use of magnetic levitation (MAGLEV) to aid the take-off and landing of the transport aircraft. The “Integrated Ground and on-Board system for Support of the Aircraft Safe Take-off and Landing” – GABRIEL, deals with radically new integration of the MAGLEV technology into the air transportation system that contains aircraft, airport, air traffic control, authority, logistic and operational support, maintenance, etc. GABRIEL idea includes operation of the aircraft without the conventional undercarriage system and using the ground based power and supporting systems for take-offs and landings. In case of using the GABRIEL system as a catapult, the aircraft on the track must be accelerated to the speed permitting to reach the altitude of 300 m or more. Such take-off and climb results in minimum noise and minimal emission of substances harmful for the environment. After reaching the altitude of 300 m, the aircraft may follow its flight with using different flight strategies. Different conditions of the unconventional take-off needs to shape other way the trajectory of the initial stage of the aircraft flight after the lift-off. The aim of the present work was to determine the optimal conditions of the lift-off and the optimal trajectory of the initial climb minimizing the emission. Simplified realization of the Ritz- Galerkin method was used in this work, which uses an approximate solution to boundary value problems for determining the optimal flight trajectory.

Opis:: This article presents a comparison of carbon dioxide emission during passengers and freight transporting by different transport modes. Because of significant diversity of transport means, the emissions expressed in grams per passenger kilometre or tonne kilometre were compared. Available data published in references were used to achieve this goal. The comparison revealed significant differences between transport modes as well as inside them, between transport means. High CO2 emission during aircrafts takeoff caused a necessity to take into account the flight distance for the air transport.
W niniejszym artykule porównano emisję dwutlenku węgla podczas przemieszczania pasażerów i ładunków różnymi rodzajami transportu. Z uwagi na dużą różnorodność środków transportu porównano emisję wyrażoną w gramach na pasażerokilometr lub tonokilometr pracy przewozowej. Do porównania wykorzystano dane dostępne w literaturze. Pozwoliło to na określenie występujących różnic dla poszczególnych rodzajów transportu, a także w ramach danego rodzaju pomiędzy różnymi środkami transportu. Z uwagi na dużą emisję towarzyszącą startowi i wznoszeniu się samolotów w przypadku transportu lotniczego konieczne było uwzględnienie pokonywanej odległości.

Opis:: Operation of vehicles equipped with combustion engines is a source of pollution. That is why the emissions from this source are restricted. The emissions reduction system consists of several steps, whose basic component is a typeapproval of vehicle in terms of emissions level and admission to the registration of vehicles that meets the requirements for emissions. It is assumed, that the gradual reduction of emissions limits will improve the emission properties of the vehicles, and gradual withdrawal of used vehicles, will reduce of emissions growth. The basis for issuing opinions on a vehicle's exhaust emissions is the measurement of emissions performed in the laboratory on a chassis dynamometer in reproducible conditions of preparing the vehicle for testing, test replication, fuel for the engine, and the procedure for collecting the exhaust gas analysis. Motor Transport Institute conducts the type approval tests, as well as the research on emissions from vehicles in the real traffic conditions, which are used to determine the actual emission from the vehicle population. Emission tests for applications, that go beyond the application of type approval show, that there are vehicles whose emissions in operation is substantially different from the emissions measured during type approval. It is a natural phenomenon in the case of used vehicles and vehicles with engine malfunctions or exhaust aftertreatment system defect. However, there are vehicles whose emissions under specific operating traffic conditions are significantly different from the values obtained in the course of type approval tests, despite the good properties of emission measured under the conditions provided by the type-approval procedure. The article discusses the results of the emissions from vehicles, obtained in the tests used to determine the emission factors for vehicles used in real traffic conditions, thus taking into account emissions from vehicles, made under different conditions than the type approval tests, which show that, in terms of driving cycles, which are not covered by the emission test procedure, can multiply and exceed the approved values.. This is particularly true for modern diesel engines.

Opis:: The article presents a method for assessing emissions of harmful substances and noise from road and air transport, as well as a combined assessment of the emissions of these transport pollutants. The original analytical dependencies reflecting the emissions of harmful substances from road transport, developed as part of the EMITRANSYS project implemented at the Faculty of Transport of the Warsaw University of Technology, were taken into consideration, in which the unit values of the actual road emissions of harmful substances are a function of, among other things, route length or speed of the vehicles. However, the dependencies associated with noise emissions were taken from the applicable international guidelines for assessing environmental pollution by traffic noise. The article also describes a case study in which the impact of Warsaw Chopin Airport on noise along the Warsaw road network and the entire Warsaw agglomeration was assessed. Analyses and discussions were carried out in the scope of the change in transport noise due to air operations carried out in the analysed area. As agreed, the combined impact of road and aircraft noise in the area under study is far more unfavourable than street noise alone. Thus, it can be seen that the assessment of noise levels carried out separately for individual modes of transport (in accordance with applicable regulations) should be supplemented with the assessment of traffic noise from all modes of transport – especially in the case of simulation tests of ecologically friendly changes in the area of transport.

Opis:: Travel is an inseparable part of human life. It is connected not only with private life but also with business life. People want to travel more, farther and faster. That is why air transport is currently one of the fastest-growing areas of passenger transport, and airlines carry more and more passengers from year to year. Due to the growing negative impact of air transport on the natural environment, research aimed at the development of technologies to reduce the negative impact of air transport is becoming more and more important. One of the possibilities for improving the situation is the use of alternative energy sources, limiting the emission of greenhouse gases into the atmosphere. The paper aimed to analyze the meaningfulness of replacing the classic power unit in a light transport aircraft with a hybrid, combustion-electric power unit. Analyzes were made with the use of simulation methods for the PZL M-28 aircraft.

Opis:: In the article the results of experimental tests carried out on the modified SI two-stroke experimental combustion engine with direct fuel injection system and the prototype of the oxidizing catalytic converter are presented. Volumetric exhaust emissions of the most important chemical components are many times smaller than standard limits of gaseous emissions given by EU directive for the new stationary engines applied in non-road vehicles and machines Spark ignition two-stroke engine fitted with a catalytic reactor is characterized by high temperature of exhaust gases, which the energy may be used in cogeneration systems. The paper presents the test stand, volumetric concentration of the main components of exhaust gases, results of converted emissions and fuel consumption as a function of air excess coefficient at chosen rotational speeds together with the assessment of the test results. There is decreasing of CO and HC emission during increasing of air excess coefficient and a strong increase of CO2 behind the catalytic converter. Application of catalytic converter in the outflow system together with direct fuel injection of the tested two-stroke engine enables to achieve values of exhaust emission of main toxic chemical components close to automobile four stroke engines. The paper presents also the comparison of exhaust gas emission of this engine with other engines equipped with different fuelling systems. Presented work is the successor of a wide range of research work in the field of development of modern two-stroke engines carried out in the Cracow University of Technology.

Opis:: W niniejszym artykule zestawiono emisję: tlenków azotu, węglowodorów, tlenku węgla i cząstek stałych dla różnych środków transportu. W zestawieniu uwzględniono transport: drogowy, kolejowy i lotniczy. Do analizy użyto danych dostępnych w literaturze. Przedstawiono je oddzielnie dla każdego z ww. rodzajów transportu. W celu ułatwienia porównania środków pasażerskiego i towarowego transportu drogowego zestawiono dane dotyczące emisji przypadającej na jednostkę drogi. Ponadto, zaprezentowano dane dotyczące emisji na jednostkę pracy przewozowej, która umożliwia porównanie transportu drogowego z kolejowym i lotniczym. Porównanie to umożliwiło określenie różnic występujących pomiędzy poszczególnymi rodzajami transportu. W transporcie lotniczym zaobserwowano istotny wpływ odległości pokonywanej w trakcie lotu na emisję. W przypadku lotów w kierunku zbliżonym do równoleżnikowego istotne jest także, czy odbywa się on zgodnie z ruchem Ziemi czy przeciwnie do niego.
This article presents data that concerns emission of nitrogen oxides, hydrocarbons, carbon monoxide and particles by different transport means. The road, rail and air transport were taken into account. The data published in references were analysed. To compare freight and passenger road transport emission expressed in grams per kilometre was presented. The emission in mg per passenger-kilometre enabled comparison of cars trains and planes in terms of air pollutant discharge. The data comparison revealed significant differences between transport modes. For aviation significant influence of flight distance on emission was observed. For flights running evenly with a parallel of latitude also the direction – according or opposite to the Earth rotation is significant.

Opis:: The paper presents regulations and methods of testing emissions of exhaust toxic components from vehicles, particularly with respect to research methods under real road traffic conditions. In Europe, legal regulations determine emission values of the exhaust toxic components: carbon monoxide CO, unburned hydrocarbons HC and hydrocarbons released by evaporation (VOC - Volatile Organic Compound), nitrogen oxides NOx, and also PM emitted with the exhaust gasses. Emission of the harmful substances from the vehicles is tested on the chassis dynamometer, and the combustion engines them, on engine test bench. Due to a high cost of the test equipment and complexity of the tests, it is possible to use one measuring system, for both types of stands. Basic EU Directives and UN-ECE Regulations contain rules on conducting the aforementioned tests together with the regulations for the measuring equipment. In the beginning of 2005 in Europe the introduction of a new set of regulations began be introduced, concerning emissions from the M1 and N1 category vehicles. They are called Euro IV (currently obligatory) and Euro V (introduced in 2008). New regulations introduced not only more stringent requirements for the vehicles they refer to, but also for the research laboratories as far as the equipment level and research methods are concerned. Compliance with these requirements is being verified during type approval of vehicles, conformity of production (COP), and in-service conformity.

Opis:: Transport is one of the most environmentally destructive branches of economy. It contributes to environmental degradation and influences negatively on human live. It should therefore seek to reduce the negative impact on the environment. The paper presents many aspects of development of the national transport system. In article characterized technical constraints and environmental issues, which are applicable to the designing of pro-ecological transport system. Presented in it also indicators of the proposed design solution quality. In shaping the pro-ecological system the special role plays environmental restrictions, because they mainly determine the quality of solutions in terms of minimizing the negative impact of transport on the environment. Technical factors are equally important, because they allow, among others, reducing the external costs of congestions and allow on the creation of transport tasks on the appropriate level. In particularly, EU requirements for sustainable development of the transport system, the components of the external costs arising from the sphere of transport, indicators and ecological limitations in designing of pro-ecological transport system, ecological limitations, technical limitations, indicators for assessing pro-ecological transport system are presented in the paper.

Opis:: Nowadays more and more attention is paid to minimizing the costs of air operations. The largest share in the cost of the flight is the cost of consumed fuel. Taking into account the external conditions, having impact on the aircraft, such as wind direction and magnitude when planning the aircraft trajectory it is possible to reduce flight time and thus reduce fuel consumption. An additional advantage is the simultaneous reduction of pollutants in the jet engines exhausts. In the times of pro-ecological trends and concepts (e.g. Clean Sky, Single European Sky, CORSIA) this aspect is of crucial importance. The emission of selected pollutants in the jet engine exhausts (NOx, CO and HC) emitted during the flight of a business jet on the route whose cruise phase was assumed 1000 km long was determined in the article. The aircraft used in the research was Gulfstream GIV, powered by two Rolls Royce TAY 611-C engines, for which a cruising altitude of 10 km and a flight speed of 0.8 Ma were assumed. The thrust necessary for the flight at these cruise parameters was set, and then the engine thrust appropriate for the flight and the corresponding specific fuel consumption were determined. On this basis, based on the available ICAO data, the emission of selected pollutants in tis engines exhausts was determined for windless conditions. Next, the analysis of the impact of wind - its magnitude and direction – on the emission of these pollutants was made. The results of the conducted analyses are presented in diagrams and discussed in the conclusions.

Opis:: Processes of the combustion of liquid fuels and solid are more complex than combustion of fuel gases. With reference to liquid fuels occur additionally processes of vaporization of the fuel, and with reference to solid fuels - decomposition of the solid phase with processes of melting and vaporization, pyrolysis, or gasification. This simultaneous and also different influence of different parameters is sometimes a reason of incorrect interpretation of experimental results. The study of the theoretical model of the combustion process concerning of liquid and solid fuels and which then the model takes into account also the gas- phase, because combustion processes take place in this phase, and occurs the interaction of the phase gas- and liquid or the solid one. The theoretical model is presented basing on experimental initial researches realized in a model with reference to liquid fuels and solid ones. Researches realized in the constant volume chamber with measurements of the pressure during the process of the combustion with the use of quick photography and with measurement of the distribution of the velocity in the spray of the fuel and droplet measurements by means the laser Doppler equipment LDV and PDPA. There were obtained a good agreement of findings experimental researches with the theoretical model. Generally on the combustion velocity of liquid fuels and solid one significant influence has a kind (laminar, temporary and turbulent) and the thickness of the thermal boundary layer.
