In recent years in Europe and in Poland a discernible trend of significant increase safety in rail transport can be observed. Safety improvement is realized at many levels and in many aspects (organizational, systematic, technical etc.). Implementation of Safety and Maintenance Management Systems are an example of activities seeking to systematically increase safety in rail in Europe. Similarly, on the part of technical solutions, there are discernible activities which are aimed at improving the safety level. There offer new construction solutions, new control systems or new communication technologies which are designed to increase reliability and safety of this mode of transport. For innovations introduced in vehicles, almost only improving safety in the field of implementing enhancements in construction of running gear systems of vehicle used to be thought about. However, it is worth remembering that not only the bogie, wheel set or wheels are responsible for the proper cooperation of the vehicle with the track and its safe running. Elements that have not been yet subjected to deeper analyzes are railway buffers whose proper maintenance and cooperation is a guarantee of correct vehicle dynamics, especially when passing through rail curves. This article presents the results of operational research of railway buffers whose heads were covered with an aluminium bronze layer. This solution has helped to increase the durability of their co-operating surfaces, and has allowed the resignation of the now-proposed solution, which consists in periodically covering buffers heads with the grease which has a lot of defects.

his article investigates the issue of the environmental impact of car transport. This topic is discussed in the context of tribological processes, which result in increased fuel consumption and consequently increased emissions of exhaust gas components. Based on data found in the literature, the share of frictional resistance in the total fuel consumption of individual cars, trucks and buses was determined. Using statistical data for Poland, the effects of friction processes in individual vehicle groups on the annual CO2 emissions from transport vehicles were also determined. The final part of the paper presents the results of the preliminary research on the possibility of lowering the friction resistance in various friction nodes found in motor vehicles by introducing carbon nanomaterials into the lubricating oils.

Artykuł poświęcony jest zagadnieniom uciążliwości transportu samochodowego dla środowiska. Problematyka ta omówiona jest w kontekście procesów tribologicznych, których efektem jest zwiększone zużycie paliwa i w konsekwencji zwiększona emisja składników gazów spalinowych. Na podstawie danych literaturowych określono udział oporów tarcia w poszczególnych zespołach samochodów osobowych, ciężarowych i autobusów w sumarycznej konsumpcji paliwa. Wykorzystując dane statystyczne dla Polski określono wpływ procesów tarcia w poszczególnych grupach pojazdów na roczną emisję CO2 ze środków transportu. W końcowej części artykułu przedstawiono wyniki wstępnych badań nad możliwością obniżania oporów tarcia w różnych węzłach tarcia występujących w pojazdach samochodowych przez wprowadzenie do olejów smarowych nanomateriałów węglowych.
