    Opis:
    W artykule wyznaczono modele masy, liczby i średnicy cząstek stałych emitowanych z pojazdów wyposażonych w silniki o zapłonie samoczynnym. Przedstawiono nowe możliwości wykorzystania wartości charakteryzujących warunki ruchu pojazdu do identyfikacji parametrów cząstek stałych. Do opisu warunków pracy pojazdu wykorzystano dwuwymiarowe histogramy, które ujmują wartości prędkości i przyspieszenia pojazdu oraz czasu jego pracy w rzeczywistych warunkach ruchu. Wynikiem tych działań jest propozycja modeli matematycznych opisujących podstawowe właściwości cząstek stałych (ich masę, liczbę i średnicę) w różnych warunkach pracy samochodów osobowych. Tworzone modele parametrów cząstek stałych wykorzystujące parametry wejściowe uzyskane w warunkach dynamicznych potraktowano priorytetowo. Badania takie, niewykonywane dotychczas, wykonano dla pojazdów lekkich, a następnie dowiedziono poprawności uzyskanych modeli parametrów cząstek stałych przez weryfikację, do której wykorzystano inne pojazdy niż użyte do tworzenia odpowiednich modeli.
    In the paper models of mass, number and diameters of particulate matter generated by vehicles fitted with diesel engines have been determined. The author presents new possibilities of application of the values characterizing the vehicle traffic conditions for the identification of the particulate matter parameters. For the description of the vehicle operating conditions two-dimensional histograms have been used that include the values of vehicle speed and acceleration and its time of operation under actual traffic conditions. The result of these actions is the proposal of mathematical models describing the basic properties of particulate matter (its mass, number and diameters) under different operating conditions of passenger vehicles. The created models of particulate matter parameters using the input parameters obtained in the dynamic conditions have been treated with priority. Such research, a pioneer one to date, has been carried out for light duty vehicles and then the correctness of the obtained models has been confirmed of the particulate matter parameters by a validation on vehicles other than those used for the creation of the models.

    Opis:
    A long service life of heavy-duty diesel vehicles results in a large number of older-technology trucks and buses of various types running on roads nowadays. Cleaning up exhaust gases of these older vehicles gives an opportunity to improve air quality at affordable costs. Retrofitting older buses with diesel particulate filters (DPF) is a cost-effective measure to quickly and efficiently reduce particulate matter (PM) emissions and contribute to mitigation of air pollution in urban conglomerates. In this paper, the milestones on a way to wide-scale retrofitting of heavy-duty vehicles with DPF are discussed on the example of Israel DPF retrofit program. Crucial importance of a balanced governmental approach combining regulation and economic incentives, together with collaboration of government, academia and vehicle operators, is underlined. Main results of the one-year pilot project focused on urban and intercity buses are discussed. Impact of DPF retrofitting on particulate emissions and engine performance and maintenance aspects of in-use diesel buses is analyzed. Very high particle filtration efficiency (in average, about 97%) together with relatively low fuel economy penalty (0.6–1.8%, depending on the bus type) are proved. Vital importance of careful monitoring and correct maintenance of DPF-equipped vehicles is underlined.

    Opis:
    The nanoparticles (NP) count concentrations are limited in EU for all Diesel passenger cars since 2013 and for gasoline cars with direct injection (GDI) since 2014. For the particle number (PN) of MPI gasoline cars there are still no legal limitations. In the present paper some results of investigations of nanoparticles from five DI and four MPI gasoline cars are represented. The measurements were performed at vehicle tailpipe and in CVS-tunnel. Moreover, five variants of “vehicle – GPF” were investigated. The PN-emission level of the investigated GDI cars in WLTC without GPF is in the same range of magnitude very near to the actual limit value of 6.0 × 1012 1/km. With the GPF’s with better filtration quality, it is possible to lower the emissions below the future limit value of 6.0 × 1011 1/km. The modern MPI vehicles also emit a considerable amount of PN, which in some cases can attain the level of Diesel exhaust gas without DPF and can pass over the actual limit value for GDI (6.0 × 1012 1/km). The GPF-technology offers in this respect further potentials to reduce the PN-emissions of traffic.

    Opis:
    W pracy przedstawiono analizę wpływu zmiany drożności filtra cząstek stałych na właściwości dynamiczne turbosprężarki Garrett GT 1544V. Zmianę drożności filtra symulowano za pomocą zaworu kulowego umieszczonego w układzie wylotowym silnika. Podstawowym parametrem pracy turbosprężarki rozważanym w ocenie była prędkość obrotowa wirnika. Na podstawie przeprowadzonych badań wykazano występowanie znacznego zmniejszenia prędkości obrotowej wirnika turbosprężarki, w przypadku spadku drożności układu wylotowego.
    An impact assessment of patency changes’ in diesel particle filters on dynamic characteristics of Garrett 1544V turbocharger has been presented in article. Changes in filters patency were simulated thanks to ball valve which was placed in engine exhaust system. Speed of turbine was main parameter of turbocharger’s operation which was taken into consideration during assessment. On the basis of realized investigations it was demonstrated that in case of patency decreasing there is significant decreasing of turbine rotor speed.

    Opis:
    Air pollution is a challenge for municipal authorities. Increased emission of PM10 and PM2.5 particles is particularly noticeable in Poland primarily the autumn and winter period. That is due to the start of the heating season. According to the above data, road transport accounted for approximately 5% of the creation of PM10 particles, ca. 7% of PM2.5 and approximately 32% for NOx. In Poland, suspended particles (PM10 and PM2.5) cause deaths of as many as 45,000 people a year. The issue of smog also affects other European cities. Therefore, it is necessary to undertake concrete efforts in order to reduce vehicle exhaust emissions as much as possible. It is therefore justifiable to reduce the emission of exhaust pollution, particularly NOx, PM, PN by conventional passenger cars powered by compression ignition engines. Emissions by these passenger cars have been reduced systematically. Comparative tests of the above emission of exhaust pollution were conducted on chassis dynamometer of such passenger car in NEDC cycle and in the new WLTC cycle in order to verify the level of emissions from this type of passenger car. Measurements of fuel consumption by that car were also taken. Emission of exhaust pollution and fuel consumption of the this car were also taken in the RDE road test.

    Opis:
    Internal combustion engines have seen a reduction of the dynamics of their efficiency growth in recent years. All kinds of new modifications and changes introduced in this field can only manage changes of engine efficiency at the level of a fraction of a percent. Considering the concept of unification of SI and CI internal combustion engine structures, one can expect to see their efficiency increase by the reduction of losses, whose causes and occurrence is commonly known. The improvement of the combustion system is mainly related to the reduction of thermal losses generated in this process. Therefore, the current issue is the advanced analysis of any possibilities of improving the combustion conditions and more fully understanding the processes that accompany them. The authors of the article see such a possibility in the conceptual control of the combustion process, which aims to obtain a combustible mixture surrounded by nonflammable gases. This way the flame contact with the cylinder walls is limited, which should in turn contribute to reducing the heat exchange with the walls. This research is a continuation of previous research work; current work focuses on determining the actual distribution of gases in the combustion chamber using the advanced shadow photography method. The article specifies the effect of nonflammable gas injection pressure increase on the area of the boundary layer formed between the non-flammable gases and cylinder walls.

    This study investigated the effect on piston assembly friction after treating piston surfaces with a fine particle bombarding process, using a friction measurement apparatus with a floating cylinder liner, similar to an eco-mileage vehicle engine. Friction was measured in four conditions: (1) no treatment (standard piston in a commercially-available engine), (2) micro dimple treatment (45 μm ceramic particles were air-blasted onto the piston surface), (3) molybdenum disulfide (MoS2) shot treatment (1 μm MoS2 particles were air-blasted onto the piston surface), and (4) combination of the previous two micro dimple and MoS2 shot treatments (first 45 μm ceramic particles and then 1 μm MoS2 were air-blasted onto the piston surface). Results indicated that friction decreased in the following order: no treatment > micro dimple treatment > MoS2 shot treatment > combination of micro dimple and MoS2 shot treatments.

    Opis:
    Condensation particle counters (CPCs) use light scattering to count particles after they have grown to micron size in a supersaturated environment. In single counting mode each particle is counted depending on whether the scattered light exceeds a threshold value or not. In photometric mode the total scattered light is converted in particle number concentration. While for laboratory grade particle number systems, CPCs are allowed to operate only in single counting mode, there is no such requirements for portable emissions measurements systems (PEMS) for real-driving emissions (RDE) testing or for instruments for periodic technical inspection (PTI) of vehicles. In this study two CPCs of the same model were assessed in single counting and photometric modes with silver and graphite particles with sizes ranging from 10 nm to 100 nm. The results showed that the concentration was measured accurately enough for particles in the 25 nm to 50 nm size range, but was underestimated and overestimated for smaller and larger particles, respectively. The key message is that the photometric mode should be avoided or calibrated in function of concentration and particle size.

    Opis:
    The solid particle number method was introduced in the European Union (EU) light-duty legislation for diesel vehicles to ensure the installation of the best-available technology for particles (i.e., wall-flow diesel particulate filters) without the uncertainties of the volatile nucleation mode and without the need of large investment for purchasing the equipment. Later it was extended to gasoline vehicles with direct injection engines, heavy-duty engines (both compression ignition and positive ignitions) and non-road mobile machinery engines. Real Driving Emissions (RDE) testing on the road with Portable Emissions Measurement Systems (PEMS) for particle number (and NOx) during type approval and in-service conformity testing was recently (in 2017) introduced for light-duty vehicles, and is under discussion for heavy-duty vehicles in-service conformity testing. This paper will summarize the existing legislation regarding solid particle number and discuss the on-going activities at EU level. The main focus at the moment is on improving the calibration procedures, and extending the lower detection size below 23 nm with interlaboratory exercises. In parallel, discussions are on-going to introduce testing at low ambient temperature, regeneration emissions in the light-duty regulation, a particle limit for other technologies such as gasoline port-fuel injection vehicles, and the feasibility of particle measurements to L-category vehicles (mopeds, motorcycles, tricycles and minicars). A short overview of periodical technical inspection investigations and the situation regarding non-exhaust traffic related sources with special focus on brakes and tyres will be described.

    This study developed a friction measurement apparatus with a floating cylinder liner in a small motorcycle engine. In this measurement apparatus, joint plates were installed in the grooves on the outer periphery of the floating liner, and then the plates, as well as load washers of piezo type, were mounted in the cylinder block at both the thrust and the anti-thrust sides. A stepped ring, protruding inward, was mounted on the top of the floating liner so that cylinder pressure acting on the stepped portion was balanced in the vertical direction. Thus, it was possible to measure the friction in the sliding directions of the piston. Using this apparatus, the effect of the engine operating period on friction was investigated in a piston micro-dimpled with a fine particle bombarding process. Results indicated that, at low engine speeds, friction decreased with the operating period, but at high engine speeds, friction decreased after 10 hours of operation, and then increased after 20 hours of operation.

    The aim of this study is to describe the impact on particle matter and CO2 emissions of converting an existing heavy-duty diesel engine for on-highway truck applications to a dual-fuel engine (diesel + natural gas), especially in transient operation. A dual-fuel engine with homogeneous gas charge injection in the intake line before turbocharger was considered. The results showed the feasibility of this kind of technology for transient operation reaching a significant reduction of particle matter plus a decrement in CO2 emissions at the expense of a small decrement of brake fuel conversion efficiency and an increment of unburned hydrocarbons in the exhaust gases.

    Opis:
    Biofuels represent one of the alternatives to obtain the CO2 - neutral propulsion of IC-engines. Butanol, which can be produced from biomass, is considered and was investigated in the last years due to the very advantageous characteristics of this alternative fuel. Butanol can be easily and irreversibly blended both with light (gasoline) and heavier (diesel) fuels. Comparing with ethanol it has the advantages of: higher calorific value, lower hygroscopicity and lower corrosivity. It can replace the aviation fuels. This paper presents the emission results obtained on two diesel passenger cars with different technology (Euro 2 and Euro 6c) and with addition of butanol to diesel fuel, as a part of the research project DiBut (diesel and butanol). Interesting results are given about some non-legislated (non-regulated) components, acetaldehyde (MeCHO) and formaldehyde (HCHO) and about the PN-emissions with/without DPF.

In this study we tested a 1000 cm3 Euro 5 motorcycle over the World Harmonized Motorcycle Test Cycle (WMTC). The gaseous pollutants were approximately half of their respective limits. The cold start (first 2 minutes) contributed to the majority of the emissions. The solid particle number emissions were also 6.5 times below the limit for passenger cars, but the particles not counted with the current methodology were around 2 times higher. High concentrations of volatiles were emitted at the high speed part of the cycle.

    Opis:
    The main advantages of using direct injection in an SI engine, such as lower fuel consumption and higher thermal efficiency, implicate a new problem concerning gasoline engines: the emission of particulate matter. The observed issue has been a significant direction of development of the contemporary DISI engine over the last decade. This paper contains an overview of the results of PN emission, which were obtained from experiments conducted at BOSMAL and from the literature. Current and future legal regulations regarding PN emissions were collated to the test results.
    Główne korzyści z zastosowania bezpośredniego wtrysku benzyny w silnikach ZI, takie jak mniejsze zużycie paliwa czy większa sprawność termiczna silnika, wiążą się także z problemem niespotykanym dotąd w silnikach ZI, tj. z emisją cząstek stałych. Przez ostatnią dekadę zjawisko to wyznaczyło kierunek rozwoju współczesnych silników benzynowych z bezpośrednim wtryskiem. Artykuł ten zawiera przegląd wyników badań emisji liczby cząstek stałych w trakcie różnych projektów badawczych zrealizowanych w Instytucie BOSMAL, a także przedstawionych w literaturze. Wyniki odniesiono do obecnych i przyszłych wymogów prawnych dotyczących emisji cząstek stałych.
