Opis:
Costs for tolling a motorway in Poland should take into account not only profits of owners and managers, but also difficulties and losses incurred by road users. Lack of smoothness of travel as well as high tolls do not have a positive impact on the country's economic development. The nervousness and stress of drivers and passengers trapped in cars standing in traffic jams in front of the gates on motorways - they indicate an important social problem. The costs of fuel burnt during forced stops, costs of harmful effects on the environment, pollution from car exhaust emissions while waiting on the highway in front of the gates – they all are a significant burden. Failure to ensure the conditions for a smooth ride causing the need to wait on the highway in front of the gates is an example of disregarding people, wastage and deliberate harm to the environment for disproportionate profits charges for using the highways.

Opis:
The development of marine diesel engines has so far been directed towards increasing their power, reducing fuel consumption, burning fuels of the lowest possible quality and the extension of operation time. The rising pro-ecological pressure has made atmosphere pollution by exhaust gases of marine engines one of the main problems of environmental protection of recent years. The Gdansk Bay area, just like sea ports or coastal regions, is vulnerable to the effect of noxious compounds contained in vessel exhaust gases, besides those coming from industrial plants, power plants or vehicles. This concerns vessels both in ports and in the roads. In order to determine the share of vessels in environmental pollution and to counteract the harmful effects of toxic compounds in marine engine exhaust gases, it is necessary to know the emission values of these compounds from particular vessels, which is possible with the knowledge of their movement parameters, concentration values of particular compounds for these parameters and the atmospheric conditions. The report presents problems of modelling the NOx emission in exhaust gases from main marine Diesel engines, such as problems with construction special models describing the marine vessels movement or define real value of toxic compounds emission.

W referacie przedstawiono wyniki badań doświadczalnych doładowanego, cztero- cylindrowego silnika o zapłonie samoczynnym o objętości skokowej 1,7 dm3 z bezpośrednim wtrys. iem paliwa. W badaniach szczególny nacisk położono na możliwość uwzględnienia sterowania dawką paliwa, kątem wyprzedzenia wtrys. u, stopniem recyrkulacji spalin oraz temperaturą i ciśnieniem ładunku w kolektorze dolotowym w celu określenia zawartości składników toksycznych i zadymienie spalin. Wyniki badań przedstawiono w postaci funkcji aproksymacyjnych wielu zmiennych. Zmiennymi są wymienione powyżej parametry regulacyjne silnika. Przedstawiono analizę wyników badań i wskazano możliwość zastosowania wyznaczonych funkcji aproksymacyjnych w optymalizacji parametrów regulacyjnych silnika, której celem jest dobranie takich wartości parametrów regulacyjnych, które zapewniają zmniejszenie zawartości tlenków azotu w spalinach przy dopuszczalnej zawartości innych składników toksycznych oraz przy zachowaniu założonych wartości parametrów eksploatacyjnych silnika.
In the paper the results of experimental investigations on a turbocharged, four-cylinder direct injection SI engine with the displacement of 1.7 dm3 are presented. In the investigations, particular attention was paid to the possibility of including the control of fuel dose, injection advance angle, exhaust gas recirculation rate and the temperature and pressure of air charge in the inlet manifold with the intent to determine the content of the toxic components and the smokiness of exhaust gases. The results of the investigations are presented in the form of approximation functions of several variables. The variables are the engine control parameters mentioned above. An analysis of the investigation results is presented and a possible application of the approximation functions in the optimisation of engine control parameters is indicated with the aim of selecting such values of control parameters as would guarantee a reduction of the nitrogen oxides content in the exhaust gases while maintaining the content of other toxic components and the assumed engine exploitation parameters on an acceptable level.

Opis:
An airport authority needs accurate information about the actual amount of harmful emissions being generated within its airspace, to be able to take measures leading to their reduction. This article presents two methods for estimating the amount of these emissions from aircraft engines during the take off and landing cycle (LTO) in the airspace of a medium-sized airport: one based on the total amount of the aircraft annually operated in it, and a second, more precise, one for a specific airline annually operating at this airport. The conclusions stemming from the comparison of these methods can support the introduction of operational and technical procedures reducing harmful emissions in the airport airspace during LTO cycle.

Opis:
his article investigates the issue of the environmental impact of car transport. This topic is discussed in the context of tribological processes, which result in increased fuel consumption and consequently increased emissions of exhaust gas components. Based on data found in the literature, the share of frictional resistance in the total fuel consumption of individual cars, trucks and buses was determined. Using statistical data for Poland, the effects of friction processes in individual vehicle groups on the annual CO2 emissions from transport vehicles were also determined. The final part of the paper presents the results of the preliminary research on the possibility of lowering the friction resistance in various friction nodes found in motor vehicles by introducing carbon nanomaterials into the lubricating oils.

Optimization procedure of the si engines feeding systems requires the application of newer and more sophisticated tools, as an addition to well known but expensive experimental methods. Numerical methods can be considered nowadays as once playing the most important role in the combustion process analysis. Paper describes the application of the dual zone model, allowing the analysis of the combustion process in an SI engine with the possibility of estimating 10 different exhaust gases i.e.: CO2, CO, H2O O2, NO, N2, H2, H, O and OH. The research has been carried on a 1.6 litr es four cylinder SI engine, fed with petrol and alternatively with LPG and CNG. In-cylinder pressure for the 4th cylinder of the tested engine has been acąuired for several engine speeds. registered in-cylinder pressure traces p=p((fi), together with the volume variation nii=nii((fi) infunction ofcrank angle, were used in the combustion process simulating calculations. Obtained results made it possible to compare selected parameters describing the combustion process. Obtained results do also prove recognized fact related to the higher temperature necessary to initiate gaseous fuel combustion.

Opis:
Particulate matter (PM) and gaseous compounds (SO2, NOx, VOC) emitted by diesel engines causes serious global environmental problems and health impact. Despite numerous evidences about the harmfulness of diesel particles, the PM emission by diesel engines used by ships, cars, agricultural machines, or power generators is still unregulated, and the efficient removal of PM from diesel exhausts is still the major technological challenge. In order to comply with the International Maritime Organization regulation, the NOx emission is reduced by using selected catalytic reactor, and sulphur oxide emission has been reduced by using fuels of low sulphur content. However, both of those measures cannot be used for the reduction of PM emission produced during combustion of marine fuels. The lack of appropriate regulations results from insufficiently developed technology, which could remove those particles from exhaust gases. Conventional scrubbers currently available on the market remove only sulphur oxide with required collection efficiency, but the collection efficiency for PM2.5 is below 50%. The article discusses the technical means used for the removal of PM from marine diesel engines via applying electrohydrodynamic methods, in particular electrostatic agglomeration, as a method of nanoparticles coagulation to larger agglomerates, which could operate in two-stage electrostatic precipitation systems, and electrostatic scrubbers, which remove particles by electrically charged water droplets. The experimental results were obtained for a 2-stroke 73 kW diesel engine fuelled with marine gas oil (MGO). The agglomerator allowed increasing the collection efficiency from diesel exhausts for PM2.5 particles by about 12%, compared to electrostatic precipitator operating without agglomerator, and the total mass collection efficiency was above 74%. The collection efficiency of electrostatic scrubber was higher than 95wt.%. The advantage of using the electrostatic scrubber is that it can also reduce the SO2 emission by more than 90%, when HFO is used.

Opis:
The paper deals with problems of model analysis of the process of exhaust gases components formation in internal combustion engine working with combustion initiation from ignition dose of fuel injected directly into the working space. In result of scientific-research works carried out in the Chair of Internal Combustion Engines of Cracow University of Technology on the basis of a four stroke engine a driving unit was elaborated which may work both with spark ignition and combustion initiation from a ignition dose of fuel. Application of two combustion systems in engine aimed at combining the advantages of spark ignition with compression ignition driving units. Such an engine is characterized by fuel consumption comparable with that gained by compression ignition engines, whereas, the exhaust gases composition is similar to that occurring in up-to-date spark ignition engines. Similar assumption concern the Homogenous Charge Compression Ignition - HCCI system which seems to be a future solution of internal combustion engines, nevertheless, up till now, in spite of intensive works in many countries all over the world, one did not succeed to control the combustion process in a large range of rotational speeds and loads what would give the possibility of using it in traction application. The solution proposed in the patent application by Prof. B. Sendyka is not burdened with this drawback since the moment of occurrence of volumetric ignition of the formed mixture in the process of filling is tightly connected with the moment of fuel dose injection. In result of simulative studies carried out by use of KIVA-3V software on the discussed solution it was stated that the process of exhaust gases toxic components formation in engine working in the mode of ignition from pilot dose does not depart in generally form from that which occurs at work with spark ignition.

Based on the available information and authors self-assessments, this article presents turbine engine exhaust gases effect on the environment, especially near to the aircraft and helicopters during their engines idle setting and take-offs. The concentration level of pollutants in gas turbine exhaust and its relation to the temperature and time of the combustion process is discussed. The article presents diffusion of the aircraft turbine engine exhaust in the airport area, focusing on aircraft take-off manoeuvre. The authors would like to draw attention of the aviation professionals to the fact that amount of exhaust from the turbine engine is so significant that may adversely change the ambient air near to the aircraft. Consequently, smaller amount of oxygen with increased level of carbon monoxide during engine start –up and idle can be a threat to the maintenance staff health. Also high emission level of the nitrogen oxides, especially during take-off and climb is indifferent for the environment. The paper gives an example of real fuel consumption and toxic gases emissions in the so-called landing and takeoff cycle (LTO) and during long-range flight. Turbine engines noise distribution and its intensity because of complex aerodynamic and thermodynamic processes is presented.

We developed a concept and calculated an efficiency of the electrochemical cycle of converting low-grade heat (temperature difference 10-80°C) into electricity. The cycle could be divided into two stages: creating a concentration difference by a solution distilled in a temperature gradient and electricity generation in concentration galvanic cell. The calculation shows that the efficiency of converting heat into electricity could reach 40-55% of Carnot efficiency in a temperature range of 0-100°C in the case of use of a multi-cascade distiller. The calculations show that ratio power/mass of the device is too low to be used in automobile or air transport, but it could be used in water transport.

The article presents future requirements concerning emission of toxic components of exhaust gases valid for Diesel engine passenger cars. Questions connected with fulfilment of these standards were discussed. Chosen structural solutions permitting fulfilment of future requirements concerning emission were presented. In Europe passenger cars equipped with Diesel engines which get the homologation certificate for the first time the emission limit determined by the standard Euro 6 will be binding from year 2014. The relation to the at present binding limit Euro 5 emission of nitric oxides, the sum of hydrocarbons and nitric oxides as well as emission of particulate matter must be reduced. On the European market use could be made of experience gained during exploitation heavy duty vehicles in which decrease in nitric oxides emission is achieve by means of selective catalytic reduction (SCR). A more complex system of emission appraisal is valid in USA and especially in the states where the so called Californian standards were adopted. On the example of Volkswagen 2.0 TDI engine it was shown that in modern constructions of combustion engines there is still a large developmental potential. In this case the development went in the direction of fulfilment of new very requiring standards of emission of toxic components of exhaust gases. Well known in Europe 2.0 TDI engine which in its new version fulfils the most strict emission standards BIN5/LEV II constitutes the structural basis of the drive unit designed for the American market. Under such conditions the firm Volkswagen belongs to the small number of cars producers who for a couple of year have offered with success, passenger cars equipped with Diesel engines.

The paper presents selected results of tests on the Fiat Panda I car powered by 1.2 dm3 spark ignition engine. The engine had production installed fuel system with the single-point petrol injection. To improve its in-service performance, the engine was fitted with the multi-point injection fuel system. The assessment of the indicators of the work of the engine, fitted with single-point, or alternatively, multi-point injection fuel system, was conducted on the basis of the tests performed on the MAHA chassis dynamometer. First, tests were run for single-point injection fuel system. Next, the same tests were performed when the engine was fitted with the multi-point injection fuel system. In the tests, engine power, torque, fuel consumption and the concentrations of the exhaust gas components were measured. The latter included carbon monoxide CO, carbon dioxide C02, hydrocarbons HC, nitrogen oxides NOx, and oxygen 02. AVL Digas 4000 exhaust gas analyser was used to take measurements of the concentrations of the basic components of the exhaust gas and of the excess air ratio %u03BB. The investigations were conducted by performing the inertia test and by using the dynamometer to determine the basic indicators of the engine operation. In the investigations, the crankshaft rotational speed ranged from 1500 to 6500 rpm with 500 rpm step. The experimental results made it possible to evaluate how the manner and site of fuel delivery affect the engine -work indicators.

Opis:
The typical combined heat and power plants requires the introduction of additional heating medium. The alternative solution is the direct integration of the exhaust gases from heat engine. The high temperature, surplus oxygen and low water content of the GTs exhaust gases enabled the successful integration at industrial scale as: preheated combustion air for industrial furnaces, heat source for drying and for absorption chillers. The article comprises the reference list for direct exhaust gas integration of GTs produced by GE, the processes overview, GTs selection criteria, as well as the review of documented GTs applications in process industry focusing on technical and economic considerations. The described solutions allowed to reduce the specific energy consumption in the range from 7 to 20% or the costs of energy consumption by 15-30%. The overall efficiency of cogeneration plant above 90% was achieved. The preliminary assessment of potential applications for GTs produced by GE with TEG integration in Polish process industry is done.
