Opis:: The article presents the results of investigations concerning the relations between the technical state of cars and the exhaust gasses emission for different groups of vehicles. First, the measurements of the test group of4000 different vehicles have been made. Those measurements have been elaborated in order to define typical damages of vehicles. The percentage of faulty vehicles and the type of faults was estimated. The damages of vehicles have been carried out using typical diagnostic methods, electrical value measurements and exhaust gasses analysis. Those measurements also provided information about the number of vehicles with high level of gas emission. The results of investigations were compared to the requirements of each model of a given year. Next, the measurements of the test group of 1000 vehicles have been made in accordance with ECE Regulations and the methodology of periodical car inspection. Those measurements also gave information about the level of emission from each vehicle. The results of investigations were compared to the requirements of each model of a given year and the percentage of high polluting vehicles has been presented. The vehicles have been divided into different exhaust emission legislation classes. Next, the relation between the number of faulty vehicles and the level of exhaust emission for the first and the second group of vehicles has been elaborated and presented. The results of investigations and analysis show the number of faulty vehicles and its influence on the level of emission.

Opis:: The article presents the results of investigations of the influence of vehicle age on traffic exhaust emission. The measurements of the test group of 500 different vehicles have been made in accordance with ECE Regulations and the methodology of periodical car inspection. Those measurements provided Information about the level of emission from each vehicle and allowed to identify high polluting vehicles. The percentage of faulty vehicles and the type of faults were estimated. Next, the percentage of high polluting vehicles has been estimated. The results of investigations were compared to the requirements of each model of a given year. The percentage of high polluting vehicles for each model of a given year has been presented. The vehicles have been divided into different exhaust emission legislation classes. The percentage of high polluting vehicles for each exhaust emission legislation class has been elaborated. Next, the relation between exhaust emission and the vehicle age has been made and presented. The pro bability ofexceeding the standardized exhaust emission for each model of a given year of vehicles has been calculated. The calculations included the exhaust emission such as carbon monoxide and hydrocarbons. The likelihood of carbon monoxide and hydrocarbons emission violations have been estimated applying logit analysis. The calculations have been made in two cases, for manufactures and national emission standards. The results of investigations and analysis show that vehicle age plays a significant role in determining exhaust emission test results.

Opis:: This paper considers the results of studies on examination methods in scope of environmental protection such as exhaust emission, fuel consumption and noise emission. The reduction of exhaust gas emission of modern compression and spark ignition engines requires an optimization ofexisting diagnosing methods as well as the investigation of new approaches. The results of car inspections regarding environmental protection for more than four thousand vehicles have been compared to the requirements of ECE regulations and those of particular car producers. Eight hundred cars with a fault of gas emission and fuel consumption were examined in order to define typical damages. The possibilities of diagnosing the damages of mechanical and electrical systems of the engine have been carried out using electrical value measurements and exhaust gases analysis. The test results show that there is a necessity of elaborating new diagnosing methods enabling to find damages regarding exhaust emission and fuel consumption at their initial stage. One of the possible methods which could be applied is the evaluation of the quality of combustion process considering the values of parameters of engine performance coming from the detectors mounted to the engine. The so far carried out examinations have revealed that some mechanical damages of engines such as operating wear or unexpected faults do not make the diagnosing system react to the information.

Opis:: The article presents the results of the simulation of the traffic emission from vehicles for different type of roads. The calculations of emission have been made by using the methodology which is used in Europe. To register the number and the type of vehicles for each road a digital camera was used. The traffic stream has been recorded in the same length of time. The investigations have been made for different classes of roads with different types of vehicles. There was estimated number of the vehicles per vehicle category and the agę structure of the vehicles for each type of road. The vehicles have been divided into different exhaust emission legislation classes. Additionally, measurements of the group of 300 different vehicie have been made. Those measurements provided information about the level of emission from each vehicle. The total vehicle emission was calculated depending on the type of road, the number of vehicles, the number of vehicles per vehicle category, the age structures, the average speed per vehicle type etc. At first, the simulation of the traffic emission from vehicles was made, taking into consideration the fact, that the vehicles are in good technical conditions. Next, the calculation was made for real technical conditions of vehicles. This investigation has shown that the technical conditions of the vehicles have an important influence on the estimated emission level.

Opis:: The article studies the data from a weekly campaign devoted to the study of the elemental composition of PM10 in a selected receptor, in a suburban area (Mazowieckie Voivodeship). The sampling point was located at the intersection of main roads and in the vicinity of a typical single-family housing, not far from the electrified Warsaw-Białystok railway line and a small heating plant. The research was carried out in the summer season, in order to minimize the impact of municipal emissions on the concentrations and elemental composition of PM10. A Horiba PX-375 X-ray fluorescence spectrometer was used to measure the one-hour concentrations of elements related to PM10. On the basis of the obtained results, the enrichment factors for PM10 in the analyzed elements (EF) were calculated and the principal components analysis (PCA) was performed. It was found that although the elemental composition of PM10 in all tested time intervals was noticeably influenced by the emissions from transport, the municipal emissions had a significant impact on the elemental composition, especially those related to coal combustion, and thus the concentration of PM10 during the study period. It seems that the possibility of observing the influence of all relevant sources on the composition and concentration of PM10 was possible owing to the use of hourly-averaged measurements of the elemental composition of PM10. In the case of daily averaged measurements, in a receptor with such PM10 elemental profile, it would be impossible to determine the periods, in which specific – qualitatively completely different – emission sources dominate.

Opis:: The total emission level is heavily dependent on the number of vehicles. Additionally, the type of vehicles and their age structures are very important. The structure of vehicles also depends on the type of the road. The article presents the results of calculations of the pollutants emission from the road transport. Total emission was calculated with combination of the investigation results i.e. the type of vehicles and their age structures for different types of roads. The investigations have been made for different classes of roads with different types of vehicles. The traffic line has been recorded in the same length of time. On the basis of analysis of the recorded traffic line, the number and the type of vehicles have been estimated. The classification of vehicles have been made according to the level of emission i.e. passenger cars, light duty vehicles, heavy duty vehicles, busses and others, taking into consideration the age structures of vehicles. The level of total traffic emission has been calculated on the basis of results. There has been used the Copert programme methodology. The results of the calculations have been made with combination of the type of road, the speed of vehicles, the type of vehicles and their age structure, are presented.
Poziom emisji zanieczyszczeń zależy przede wszystkim od liczby pojazdów poruszających się po drodze. Dodatkowo istotne są struktury rodzajowa oraz wiekowa pojazdów. Struktura pojazdów zależy natomiast w dużym stopniu od rodzaju drogi. W pracy przedstawiono wyniki obliczeń poziomu emisji wybranych składników spalin emitowanych w ruchu drogowym. Obliczenia zostały przeprowadzone z uwzględnieniem wyników badań struktur rodzajowej i wiekowej pojazdów dla różnych typów dróg. Badania strumienia pojazdów wykonano na drogach różnej kategorii, przy różnej strukturze pojazdów. Rejestrowano strumień pojazdów w określonych odcinkach czasowych. Na podstawie analizy obrazu zarejestrowanego strumienia określono liczbę i rodzaj pojazdów. Pojazdy podzielono na kategorie według poziomu emisji, tj. samochody osobowe, samochody dostawcze, ciężarowe, autobusy i inne, uwzględniając strukturę wiekową. Na podstawie uzyskanych wyników oszacowano poziom emisji szkodliwych składników spalin. Obliczenia zostały wykonane za pomocą metodyki przyjętej w programie Copert. Przedstawiono wyniki szacunkowego poziomu emisji spalin w zależności rodzaju drogi, prędkości jazdy, struktur wiekowej i rodzajowej pojazdów.

Opis:: The article presents the results of the investigations of the influence of different factors on the traffic exhaust emission. The measurements of the test group of 300 different vehicles have been made. Those measurements provided information about the level of emission from each vehicle. Additionally, the investigations provided information about factors such as mileage, model year etc. of vehicles. Next, the percentage of fault vehicles and the type of faults were estimated. The relation between exhaust emission, vehicle age and mileage of vehicles have been made. The simulation of the traffic emission from vehicles was made, taking into consideration the fact that the vehicles are all in good technical conditions and for the case of real technical conditions of vehicles. This investigation has shown that the technical conditions of the vehicles have an important influence on the estimated emission level. Additionally, it has been shown how the exhaust emission depends on the age structure and the mileage of vehicles.
W artykule zaprezentowano wyniki badań wpływu wybranych czynników na wzrost poziomu emisji toksycznych składników spalin. Przeprowadzono badania stanu technicznego pojazdów z uwzględnieniem poziomu emisji poszczególnych składników spalin dla grupy 300 pojazdów. Dodatkowo uwzględniony został przebieg oraz wiek badanych pojazdów. W wyniku przeprowadzonych badań uzyskano informacje dotyczące liczby pojazdów, które przekraczają dopuszczalny poziom emisji. Wykonano charakterystyki przedstawiające zależności pomiędzy emisją poszczególnych składników spalin a wiekiem pojazdów oraz przebiegiem. Dodatkowo, przeprowadzono badania symulacyjne wpływu stanu technicznego pojazdu na obliczany poziom emisji gazów spalinowych. Wyniki przeprowadzonej symulacji pokazują, iż stan techniczny pojazdów wpływa na szacowany poziom emisji spalin. Rezultaty przeprowadzonych badań wykazały, że uwzględnienie stanu technicznego pojazdów może mieć znaczący wpływ na szacowany poziom emisji w ruchu drogowym.

Opis:: The concentration, chemical composition, and mass closure of various fractions of ambient particulate matter (PM) were analyzed at crossroads and at a highway in Katowice (Poland). It was shown that at both sites organic carbon can constitute even 57% of the fine PM mass, about 20% of the fine PM mass can originate from the photochemical transformations of inorganic gaseous precursors, and that the coarse PM was mainly the organic matter (up to 39%) and crustal matter (up to 24%). Traffic emissions in Katowice can affect the formation of secondary aerosol (organic and inorganic), the contributions to PM and ambient concentrations of soil matter, NaCl, and trace elements. At the highway, the greatest impact on the concentrations and chemical composition of fine particles was probably due to exhaust emissions. At the crossroads, in the center of the city, the non-exhaust traffic emissions probably affected the coarse PM.

Opis:: Traffic is a major source of pollutant emission in cities. In order to evaluate the air quality in urban areas it is necessary to use appropriate traffic flow and exhaust emission models. In air quality studies, the common approach of constant average emission intensity is used for describing emission along a whole road i.e. one road - one linear source. This approach can not be used in case of analysing local air pollution caused by traffic on roads between intersections and on roads with input or outputs. In the paper a method of dividing road on several segments is presented. Each segment represents linear source of emission. The method enables modelling of exhaust pollutant emission intensity taking into account its local changes. The average speed of traffic flow and density of vehicles is obtained from microscopic traffic flow model. Next, average exhaust pollutant emission intensity is calculated using the average emission factor method (European models COPERT or INFRAS can be applied). Some calculation results are presented in the paper as well. The algorithm of dividing road on segments using microscopic traffic flow model presented in the paper is a solution which enables more precisely identification of regions in which the exhaust emission is high and the permissible concentration of vehicle exhaust pollutant can be exceed.
