Opis:: In this paper are presented results of dual fuel diesel engine bench testing carried out by author. The engine was fuelled parallel with two fuels. The second, additional fuel was compressed natural gas (CNG). CNG was injected into engine inlet system before inlet to engine turbocharger. There was installed a pressure transducer in one of engine cylinders and cylinder pressure was registered at the time of testing. There is discussed place and way of pressure sensor installation and impact on quality of indicating signals of the channel connecting the transducer with combustion chamber. The carried out investigations included measurement of emissions and engine indicating completed with the heat release characteristics. There was considered influence of CNG on CO, NOx, THC and NMHC emissions, especially how pollutant emissions depend on the share of methane in fuel. The effect of using natural gas as an additional fuel injected to regular CI engine on heat release rate was investigated, as well as its rate and duration. Discussed the differences between combustion of methane and diesel oil and ways of spreading flames into air-fuel mixture for these two mixed fuels The processes of combustion of diesel oil and methane are totally different. The study searches for the limits of methane content due to knocking combustion. Additive of methane to the diesel fuel is a reason of retarded heat release, decrease of engine efficiency, greater fuel consumption and changes in emissions corresponding to the lag of self-ignition

Opis:: Tests have been carried out to evaluate the performance, emissions and heat release characteristics of a double cylinder direct injection diesel engine fuelled with tyre pyrolysis oil and diesel oil. The combustion parameters such as heat release rate, cylinder peak pressure, maximum rate of cylinder pressure, combustion knocking were also analysed. For purposes of this work raw pyrolysis oil was derived from waste vehicle tyres through vacuum pyrolysis realized in experimental installation. Results showed that the brake thermal efficiency of the engine fuelled with pyrolysis oil increased. THC, CO and CO2 emissions were found to be higher due to high aromatic content and longer ignition delay, whereas NOx shows increasing tendency due to greater heat release rate. The cylinder peak pressure did not change. The ignition delay became greater what can be the reason of problems with combustion knocking. Pyrolysis oil has a mass fraction of individual elements similar to diesel fuel but the chemical composition of hydrocarbons included in these fuels is different. The product of pyrolysis contains too much soot, sulphur, light and heavy hydrocarbons fractions for direct using it in engine. Aromatics content gives this fuel a distinctive smell. Pyrolysis oil is toxic and dangerous in use due to the polycyclic aromatic hydrocarbons (PAH). However raw pyrolysis oil is not suitable to use it as a CI fuel and requires additional distillation before using it in diesel engines as an alternative fuel in the future.

Opis:: The article discusses the results of bench tests that monitor the increase of NO₂ emissions in the heavy duty vehicles engines exhausts as a result of the use of particulate matter filters. The use of passive particulate matter filters inevitably leads to an increase in NO₂ emissions from the engine. The particularly intensive increase in the emissions occurs when SCR reactors are shut off, which is still a common practice among drivers. NO₂ concentrations in exhaust gases of DPF-equipped engines reach concentration dangerous for human health and life. The causes of the NO₂ formation in the vehicles’ exhaust systems, the harmfulness of this chemical, and the results of NO₂ measurements in different tests, are discussed. In addition, the effect of the presence of this compound on the accuracy of opacity measurement is discussed.

Opis:: Rapeseed oil in a few applications can be used as an engine fuel. Although it has worse properties than its methyl esters, it can be considered as an alternative fuel in engines adapted to its use. The article describes some problems resulting from the use of pure rapeseed oil as a fuel for compression ignition internal combustion engines. Differences between basic physical and chemical properties between diesel oil and rapeseed oil will be discussed and their impact on the theoretical engine performance and emission of pollutants from the exhaust system, with a focus on viscosity of rapeseed oil and the impact of this parameter on the fuel injection process. The basic changes in the engine design to be able to run on the rapeseed oil are discussed. The results of author’s own tests of the engine adapted to operate on the rapeseed oil and its blends with diesel oil carried out on the engine dynamometer test bench are presented. The theoretical assumptions presented in the Introduction were tested experimentally in the dynamometric test. Combination of higher density of rapeseed oil and its smaller stoichiometric value caused by the presence of oxygen and a smaller share of hydrogen in the fuel, means that a larger mass of fuel can be injected into the charge compressed into the cylinder. Thanks to this, the engine powered by rapeseed oil and diesel oil can reach similar powers.

Opis:: This article presents the problem of the knock combustion in a dual fuel compression engine, in which additional fuel besides diesel oil was compressed natural gas (CNG). CNG was injected into the engine intake system and mixed with air supplying the engine. In this paper described the reasons of knock combustion, which occur with more intensity with the increase of methane content in engine fuel. The phenomenon of knock combustion in the dual fuel engine is difficult to eliminate, often impossible to avoid, and it forms a barrier limiting increase of methane share in the fuel. Also, this article contains the results of engine indicating and discussion on changes in the indicating diagrams caused by knock combustion. Carried out tests included engine indicating and numerical calculation of indicator diagrams with using spectral analysis and filtering cylinder pressure signals with high-pass filters. As a result of this calculation, several parameters describing intensity of knock combustion were determined. They allow to tell taking into account only cylinder pressure analysis if there is knock combustion inside engine combustion chamber or not. Knocking is an undesirable type of combustion in the engine, leading to excessive thermal and mechanical loading of the engine parts, causing premature wear of them. For this reason, this type of combustion should be eliminated from the engine operation and researchers of combustion processes must be provided with tools to detect and determine this kind of combustion.

Opis:: Na świecie opracowano wiele cykli badawczych używanych do wyznaczania emisji toksycznych składników spalin z układów wylotowych silników. W niniejszej pracy porównano wyniki badań emisji zanieczyszczeń z silnika stosowanego do napędu autobusu, zmierzone na stanowisku hamownianym przy zastosowaniu trzech różnych cykli badawczych symulujących nieustalone warunki pracy silnika. Użyte w badaniach cykle pomiarowe to European Transient Cycle stosowany w homologacji europejskiej, Heavy Duty Diesel Transient Cycle stosowany w USA oraz Non Road Transient Cycle, stosowany przy homologacji silników maszyn ruchomych. Cykle te porównano ze sobą dokonując ich analizy statystycznej poprzez określenie funkcji rozkładu częstości występowania momentu i prędkości obrotowej silnika. Przeprowadzono dyskusję nad otrzymanymi wynikami pomiarów emisji, wykazano różnice w średnich parametrach charakteryzujących porównywane cykle badawcze uzasadniając tym uzyskane wyniki pomiarów emisji. Praca stanowi próbę odpowiedzi na pytanie, czy jest możliwe zamienne stosowanie cykli badawczych do wyznaczania wskaźników charakteryzujących właściwości emisyjne silnika i czy w wyniku zamiany cyklu badawczego można spodziewać się otrzymania podobnych wyników ?
There are many test cycles used for measurement of pollutant emissions from exhaust systems in internal combustion engines. In the paper are compared results of pollutant emissions testing in three different test cycles simulating transient conditions of engine operating in bus. There were used following test cycles: European Transient Cycle used in European type approval testing, Heavy Duty Diesel Transient Cycle used in USA and Non Road Transient Cycle used in type approval testing for off-road engines. These cycles were compared by using statistic analysis as well as drawing of histogram for engine torque and speed. In discussion about test results are indicated differences between mean parameters specific for each cycle. These differences are the reason why emission test results for each cycle are different. Author of this paper wanted to find answer to following question: is it possible to replace with one another emission transient test cycles and can we look forward similar emission test results for different kind of cycles?

Opis:: In the article compared emissions of pollutants measured on the same engine operating in different type approval cycles, derived from international regulations, with cycles created as a result of real engine parameter registration in different vehicles. There was tested an engine used alternatively in bus and off-road mobile machinery. It demonstrates and compares emission test results measured on the bench applying different test cycles simulating steady state and transient engine conditions. There were used following test cycles: European Transient Cycle used in European type approval testing, Heavy Duty Diesel Transient Cycle used in USA and Non Road Transient Cycle used in type approval testing for off-road engines, as well as typical steady state cycle. Though homologation tests originated as the reflection effect of real conditions of the engine performance, not less the conditions of engine performance recreated in them can differ much more from conditions met in the selected applications of engine. The article contains discussion about emission test results. The author of this paper wanted to find answer to following question: is it possible to replace with one another emission test cycles and can we expect similar emission test results for different kind of cycles as well how much emission measured in real road condition differs to the emission measured in type approval cycles?
W niniejszym artykule porównano wyniki badań emisji zanieczyszczeń silnika pracującego w wybranych cyklach homologacyjnych opisanych w różnych międzynarodowych przepisach, z cyklami opracowanymi na podstawie rejestracji rzeczywistych parametrów pracy silnika zastosowanego w wybranych odbiornikach mocy (pojazdach). Przebadano zastosowanie silnika w autobusie miejskim oraz maszynie roboczej przeznaczonej do robót ziemnych. Przedstawiono i porównano wyniki pomiarów emisji zanieczyszczeń zmierzone na stanowisku hamownianym przy zastosowaniu różnych cykli badawczych odtwarzających statyczne i dynamiczne warunki pracy silnika. Użyte w badaniach cykle pomiarowe to European Transient Cycle, stosowany w homologacji europejskiej silników pojazdów samochodowych, Heavy Duty Transient Cycle, stosowany w USA oraz Non Road Transient Cycle, stosowany w homologacji silników maszyn ruchomych, oraz cykle opracowane dla potrzeb prac badawczych. Choć testy homologacyjne powstawały jako efekt odwzorowania rzeczywistych warunków pracy silnika, tym niemniej odtwarzane w nich warunki pracy silnika mogą znacznie odbiegać od warunków spotykanych w wybranych zastosowaniach silnika. Przeprowadzono dyskusję nad otrzymanymi wynikami emisji zanieczyszczeń. Praca stanowi próbę odpowiedzi na pytanie, na ile jest możliwe zamienne stosowanie cykli badawczych do wyznaczania wskaźników charakteryzujących właściwości emisyjne silnika oraz na ile emisja rzeczywistych warunkach pracy silnika odbiega od tej wyznaczonej w czasie badań homologacyjnych?

Opis:: The work considers changes occurred in the features of the supporting structure in three categories of cars, namely: with the self-supporting body, framed body an intermediate structures between these two solutions. The area of analysis includes the length of deformation (crush) of the front al part of the car after collision with a rigid obstacle (barrier). The range of deformation is a significant factor of the passive car safety and indicates the efficiency of fulfilling the protective function for the passengers. The work shows absolute and relative (percentage and unit) variations of the car deformation, depending on the year of manufacture, including the period of 1980 - 2010. Marked trend lines indicated general nature of the deformation range variations together with the improvement of the car supporting system structures. The course of the trend line has been calculated on the basis of average deformation length values, calculated in defined periods of vehicle manufacture. Selected sections of time result from the division of the period of analysis 1980 - 2010 into six parts. The analysis of the deformation length of the frontal part of passenger cars, SUVs and pickups has been combined with simultaneous evaluation of total car length variations and their weight values. The car weight directly affects the kinetic energy of the impact so it has a significant influence on the range of deformation of the car front during collision with an obstacle.

Opis:: Emissions of greenhouse gases, such as carbon dioxide, methane, dinitrogene monoxide, water vapours and ozone was constant until the end of eighteenth century, and then began to increase. This increase was particularly steep after 1950 and continues until today. It is estimated, that changes in greenhouse gas concentrations in the air, which lasts for more than 200 years, stemmed largely from human activities, including the development of agriculture, transport and industry. The article discusses the problem of the greenhouse effect in terms of emissions of selected gases and components from the motor vehicles. It presents the results of pollutants emissions measurements, including greenhouse gas emissions from vehicles, in some research tests, curried out on the chassis dynamometer. There is assessed the impact on greenhouse gas emissions from different engine sources (exhaust system, fuel system, and crankcase) due to the following fuels: LPG, CNG, petrol, diesel oil and biodiesel. This article is a fragment of greater work devoted determination of emission indicators for greenhouse gases useful in calculation of total emissions by selected transport sectors. There are two interesting conclusion of this work: the first is that for diesel engine significant part of greenhouse gas emissions have PM emissions and the second that for older spark ignition engines equipped with open type fuel systems very important part of these emissions have hydrocarbon emissions from fuel system.

Opis:: In recent years, the interest in the use of renewable fuels in transport has increased. This is due to the European Union’s policy to reduce greenhouse gas emissions. These fuels, in addition to the effect of reducing carbon dioxide and the other greenhouse gases, may increase the emissions of other exhaust components. The article describes the problems of pollutants emissions from the engine exhaust system, related to the use of biofuels in combustion engines or their additives in conventional fuels. The influence of the chemical composition of selected biofuels on the emissions properties of vehicles and their engines will be discussed. The tests results of engines fuelled with selected biofuels, carried out by the authors of the article, will be presented. These tests will be carried out on chassis dynamometer and engine test bench, in standard research tests used in measurements of pollutants emissions like NEDC, ESC, ETC, etc. Furthermore, selected operational parameters of vehicles and engines will be compared with biofuels and conventional fuels.

Tematy:: renewable fuels
specific emissions of pollutants
Opis:: Reducing the emission of pollutants emitted from motor vehicles, and now also in greenhouse gas emissions, is a result of European Union policy. Vehicle design changes are just one way of reducing emissions of harmful substances and greenhouse gases. The second way is to change the type of fuel, by which the vehicle's engine is powered, that is the substitution of conventional fossil fuels derived from crude oil, such as gasoline or diesel fuel by so-called renewable fuels, for which the CO2 emissions are measured not only in the engine exhaust system, but also by analysis "from the source to the wheel" WTW (Well-to-wheel) - is much smaller. As part of this task the Directive 2009/28/EC introduced for all Member States to the use of renewable energy, biofuels, alternative fuels to a certain extent share of the energy and conventional fuel by 2020. This paper presents the results of measurements of emissions on the dynamometer with a diesel engine powered by six kinds of mixtures of diesel oil and rapeseed oil methyl ester (RME) – with esters containing 0 (clean diesel), 20, 40, 60, 80 and 100 (pure rapeseed oil methyl esters)% in the fuel. We analysed the reasons for the impact of changes in fuel composition on selected limited exhaust components. We found, that the addition of esters of rapeseed oil to the diesel fuel can be a reason of reducing the emissions of CO, CO2, and THC in the exhaust gases of tested engine and increased emissions of NOx and PM.

Opis:: The paper presents theoretical analysis of the properties of the rapeseed oil methyl esters and comparing them with the diesel oil properties. The essential differences in the physic-chemical properties have been emphasised, such as: Cetane number, viscosity, density, fraction content, calorific value and temperature properties of the rapeseed oil methyl esters in respect to the diesel oil. The influence of individual properties of fuels on the combustion needs to be comprehensively approached, taking into account mutual relationships between individual characteristics of diesel oil. The numbers of the basic fuel properties depend on the fractional content, such as: viscosity, density, Cetane number or surface tension influencing the course of the physic-chemical processes taking place in the self ignition engine and the combustion. The influence of many fuel properties on the combustion process is sometimes contradictory. The range of the fuel's influence on the combustion depends also on the thermodynamic parameters of the engine. The new and current problem concerning the fuels for the self ignition engines is an introduction into the operation of the rapeseed oil esters and their mixtures with the Diesel oil are an object of the paper. The question, how will the vegetable oils affect the combustion process, remains open.
