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:: 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.
