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:: 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 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.
