Opis:: The safety of buses in road traffic is very important because of potential hazards of peoples' life and health, damage and loss of freight and high costs of crash effects. The technical state of all vehicles has been examined during required periodical inspections, but in spite of this, the technical conditions of large number of vehicles have been poor. The range of inspections and their frequency have been determined according to the law of each country. The methodology and frequency has been determined in accordance with domestic legislation. The methodology of technical inspections concerns only some important systems of vehicles but not all. For example, anti-lock systems, retarders, adaptive cruise control systems, speed limitation devices etc. have not been examined. The results of examinations of 120 buses and coaches have been presented in this paper. Tests were carried out in scope of securing safety in road traffic. The methodology of compulsory periodical inspections was applied during initial tests. Vehicles were examined on typical control stands and in road tests. A special methodology for road tests for coaches with anti-lock systems was elaborated. Additional checks were carried out in cases when the results of basic tests were unsatisfactory. More than 50 vehicles of the total number of examined buses were faulty.

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:: This paper attempts to clarify what impact has selected technical maintenance tasks on the effectiveness of the braking system with special emphasis on the initial break-in period of associated components. Were conducted studies involving measurements of braking forces on a rolling station and road tests Renault Thalia of car braking during which was recorded deceleration, speed, temperature of brake discs and the force of the pressure on the brake pedal. Braking process on the rolling station was assessed with a braking efficiency ratio as a criterion. However, results collected during road tests allowed studying for more accurate of running-in process of car barking system elements. This was due to taking into account the total vehicle braking force compared with the force applied to the brake pedal. The study was performed for the discs and brake pads exhibiting a different degree of wear, with particular emphasis on the running-in elements occurring immediately after replacing brake pads. In this case, there is a noticeable loss of performance brake system, which persists after initial running in mating faces of the pad and the brake disc. This phenomenon is known from workshop car service practice, but there is a need for sensitization of staff at the Pre-reaching elements of the service operations, because operation of a vehicle with a temporarily reduced efficiency of the braking system on a public road has the potential to cause threats to the safety of road users.

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.
