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:: The International Maritime Organization set up a global strategy for reducing emission of sulphur from marine fuels, from 4.5% to 0.5% by the end of the year 2020. In order to such strategy, ship-owners need to fulfil increasing demands according to reduce pollution. New regulations, force ship-owners to reduce production of pollution, but as the devices create to remove some part of pollution are very expensive in use, began to search for cheaper and more effective solutions. The main aim of this article is to present superiority of using gas fuel over liquid fuel on ships. The construction of marine engines, run by a gas fuel is in the scope of interest of scientist’s research during the last couple of years. This branch of technology develops very dynamic recently, according to savings that can be reach while using gas engines on ships. Apart of cost reduction, new types of marine engines are able to cope with more and more restrictive regulations that are published in international convention MARPOL. Such restriction became the reason for the biggest, international corporations, specialists in engines production, to carry on long-term researches on new ways to power ship engines. One of the world’s greatest engine producer is British Rolls-Royce that became pioneer and built the first gas engine. New power unit, Bergen B-gas B35:40V is the one of the most modern type of such engine in the world. The solid construction of this engine was based on engine B32. It became very efficiently because of many rationalizations in maintenance and exploitation. Two main priorities, while developing conception for this model, were minimization of fuel consumption and operating simplification. The authors of these article present advantages of using marine engines powered by gas, according to the international MARPOL regulations that became very restrictive in order to protect marine environment. As the examples were used products of Rolls-Royce Company.

Opis:: In the paper, the authors made an analysis of mechanisms of the toxic components formation of exhaust gases in the direct injection engines. The genesis as well as the typical engine construction solution with the use of direct injection in diesel engines and these with positive ignition was developed. The typical construction solution of the Common Rail (CR) system, which is one of many elements increasing the purity of exhaust gases, was also presented. The basic advantages of direct injection, especially in case of the positive ignition engine, were also briefly described. Then, the mechanism for the formation of toxic components of exhaust gases in the direct injection diesel engines was presented. Moreover, the definition and dependency on the indicated mean effective pressure were shown, and the closed indicator graph, which is indispensable to calculate values of this pressure, was also (graphically) presented. In this paper, the mechanisms and processes, with the use of which it is possible to reduce the emission of toxic components of exhaust gases, were quoted. The exhaust gas recirculation with the EGR valve, which allows supplying the exact amount of gases to the engine inlet system, is such an example. The advantages of using this type of solutions were described, and a typical construction solution was presented in the diagram. The paper was completed with a conclusion, which emphasised the importance of direct injection on reducing the emission of toxic components of exhaust gases.

Opis:: Limiting emissions of harmful substances is a key task for vehicle manufacturers. Excessive emissions have a negative impact not only on the environment, but also on human life. A significant problem is the emission of nitrogen oxides as well as solid particles, in particular those up to a diameter of 2.5 microns. Carbon dioxide emissions are also a problem. Therefore, work is underway on the use of alternative fuels to power the vehicle engines. The importance of alternative fuels applies to spark ignition engines. The authors of the article have done simulation tests of the Renault K4M 1.6 16v traction engine for emissions for fuels with a volumetric concentration of bioethanol from 10 to 85 percent. The analysis was carried out for mixtures as substitute fuels – without doing any structural changes in the engine's crankshafts. Emission of carbon monoxide, carbon dioxide, hydrocarbons, oxygen at full throttle for selected rotational speeds as well as selected engine performance parameters such as maximum power, torque, hourly and unit fuel consumption were determined. On the basis of the simulation tests performed, the reasonableness of using the tested alternative fuels was determined on the example of the drive unit without affecting its constructions, in terms of e.g. issue. Maximum power, torque, and fuel consumption have also been examined and compared. Thus, the impact of alternative fuels will be determined not only in terms of emissions, but also in terms of impact on the parameters of the power unit.

Opis:: Around 20 percent of CO2 emitted as a result of human activity on Earth comes from transportation. One of the ideas, which lead to diminishing of the greenhouse gases emission, is reducing of fuel consumption. It may be achieved by introducing a new powertrain solutions as well as lowering overall vehicle weight. The reduction of vehicle weight may be obtained by both a new design of part and structures and application of a new materials i.e. aluminium alloys. It has to be emphasised that weight reduction is very important for combustion engine driven vehicles and electric driven vehicles as well. Mass lowering is especially desirable in the case of electric vehicles because they typically have a very narrow operational range usually lower than 200 km. Therefore even small weight reduction decreases energy consumption of EV and as a consequence increases its range, which is a crucial parameter for users. The results presented in this article were focused on high strength aluminium alloys of 6082-T6 and 7075-T6 types. Applying of those materials enables mass lowering of structures up to 50 percent, maintaining original functionality. Moreover, aluminium alloys may be also used in energy absorbing structures. The goal of tests was to obtain data required in FE analysis. In order to simulate dynamic phenomenon i.e. vehicle crash investigation of the stress-strain curves of alloys were carried out at wide range of strain rates using Hopkinson bar.

Opis:: The test procedure for the pollutant emissions from light-duty vehicles is currently under verification carried out at the international level. For this purpose, GRPE (Groupe des rapporteurs sur la pollution et energie) – the body developing UNECE regulations proposals - has set up a task group WLTP (Worldwide harmonized Light vehicles Test Procedure) which is supposed to prepare a new GTR (Global Technical Regulation) relating to this procedure. The development of light-duty vehicles, leading to the reduction of pollutants emissions, caused the increase of the requirements for their test procedure. A large number of factors associated, inter alia, with the test equipment affects its accuracy, repeatability and reproducibility. In the ongoing analysis attention is paid even to factors, which affect test results in a relatively small way, and which have been overlooked yet. One of the problems to which attention is paid is the impact of pollutant concentration in the dilution air in the CVS (constant volume sampler) system on test results. The CVS principle is accepted as the standard method to determine light-duty vehicle exhaust emissions on chassis dynamometer test cells worldwide. It was introduced in the early 1970s. One of its drawbacks is that it introduces an error resulting from the fact that the contractual DF dilution factor, rather than the actual dilution ratio DR, is used for the correction of concentration measurement results. The article discusses this error for different type of engines used in light-duty vehicles and different pollutants subject to measurements.

Opis:: The article contains the results of the simulation tests of oxidizing catalytic reactor obtained by use of the AVL Boost simulation application. The chemical reactions and the reactions rates on which computations were based are specified in this paper. The simulations were related to the influence of the catalytic reactor volume and reactor’s cells quantity influence on the carbon oxide, hydrocarbons and nitric oxides conversion levels. The influence on the nitric oxides conversion was presented in this paper as the content of NO and NO2 in NOX. The simulated computations were performed separately for the variable reactor volume ranging from 1 to 2.2 dm3 with a step of 0.4 dm3 and for the variable reactor cells quantity ranging from 200 to 600 cells per square inch with a step of 100 cpsi. As the input data for the simulation computations the actual values of the toxic compounds concentrations in the exhaust gases at the outlet of the Diesel engine were used. The measurements of the toxic compounnds were made at the chosen engine steady state work points and are presented in this paper as a graph of the toxic gases concentrations in the form of the function of the engine torque. The simulation computaitons were performed for the same points and their results are also presented in the form of the function of the engine torque. The Results presented in this paper have shown that the increase in the CO, HC and NOX conversion in the case of the oxide catalyst can be obtained both by increasing the reactor volume and its cells quantity. It also have been observed that the increase in the reactor cells quantity and volume is not proportional as regards the toxic gases conversion increase and lowers in the case of higher values of the simulated reactor parameters.

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.

Opis:: For many years research has been conducted on using water added to the process of combustion in a compression-ignition engine (by injection to the suction manifold, disintegrated in the manifold by ultrasounds, injection to the cylinder or in the form of emulsion) in order to improve the engine's operating indices and reduce its smoking and toxicity. The study presents the effects of adding water to fuel on selected toxicity indices of exhaust gases, and puts forward the problem of technical usability of a water solution of hydrogen peroxide for the discussed purposes. The effect of water proportion in fuel on the change of the engine smoking, concentration of NOx in exhaust gases in the function of water proportion of water injected, concentration of NOx in the function of rotational speed for standard fuel and emulsion fuel, the effect of water proportion in the emulsion fuel on the relative value of the engine torque, concentration of CO in exhaust gases in the function of the engine load for different water proportions concentration of NOx in exhaust gases in the function of the engine load for different water proportions, specific fuel consumption in the function of the engine load for different water proportions are illustrated in the paper.

Opis:: Socio-economic development entails the increase the number of vehicles and the need of deciding about reduction of negative effects of the air pollution growth. Tendency to reduce the emission of noxious products of diesel oil combustion in engines, treatment of the CNG as a fuel seems to be promising. It seems, that in the future, ecological aspects will matter more and more in Poland and UE, so considering ecological advantages of CNG as a fuel, probably this technology will be more widespread. Obviously, the development of this technology requires the competitive price of CNG with respect to the traditional fuels. In the article technical and economic aspects of vehicle adjustment to CNG supply is presented. Aspects of the adaptation of diesel oil and petrol engines to CNG were also brought up. Another significant factor which influence on the operating costs of using CNG were gas storage. In the paper actual methods of storage of natural gas supply are presented. Scheme of CNG feed system, decrease of emission of pollution at replacement gasoline and diesel by CNG, prices of diesel and CNG in years between 2004 and 2009, investment outlays for buying buses in public transport company in Rzeszów and numbers of natural gas vehicles in 2006 and in 2009 are presented in the paper.

Opis:: A new approach is needed to test particle filters for retrofitting Diesel engines. Considering the toxicity of the particles as also the physical and chemical attributes of particle filters, the optimal scheme is to test the components themselves independent of the deployment. That scheme ensures the highest effectiveness with least effort. It also enables evaluation of worst-case situations and assesses the hazards of secondary emissions. The Swiss standard SNR 277 205, which mandates the VERT test procedure, is a first step in that direction. Occupational health specialists have studied the toxicity of ultraflne particles for more than 100 years. Extremely toxic are the particles intruding into the lung. Larger particles, which are always naturally present, are intercepted in the upper respiratory paths. The body then expels these larger particles rapidly via the mucus and cilia. The new manmade particles less-than l mi m, however massively intrude into the fine pulmonary alveoli, which do not have the cleansing mechanism. The targeted efficiencies for evaluating modern filters are evident from the progress achieved. Many filters have filtration rates exceeding 99.9%, albeit the directives [4] only require 97%.

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:: Exhaust gases recirculation systems (EGR), together with catalytic reactors, are commonly installed in modern piston combustion engines. Their purpose is to reduce the amount of nitrogen oxides (NOx) emitted in fumes. The need for this reduction takes its source from introducing more rigorous EURO standards, which are treating about maximum levels of NOx, HC and particulates produced, as a side effect of engine's operation. Applied exhausts recirculation circuits can be roughly characterized by a principle, that a part of exhaust gases is redirected (through a cooler) and reaches a special valve. This valve, respectively to engine's current load and speed, drives more or less exhaust to suction manifold. The position of the valve determines the system’s overall efficiency, but also differentiates the amount of toxic gases and smoke produced by each of the engines cylinders. Recent research have focused only on the overall efficiency of recirculation systems, representing it by measuring the total amount of NOx particles emission from exhaust pipe. However, the quantity of exhaust gases that is reaching each cylinder can be negatively dependant on EGR valve’s physical position in the circuit. This happens due to the fact that combusted loads have different proportions of charged air and fuel. For estimating the difference among each of the loads, and in the same time, indirectly, in equal emission of NOx from corresponding cylinders, a research was carried out on a model VW 2.0 TDI engine, equipped with standard, factory mounted, exhausts gases recirculation circuit. Measurements of toxic emissions were executed with regards to thirteen-point ESC (European Stationary Cycle) test.
