Opis:: Road safety is an important social issue. Hence, changes in road traffic rules have a large influence on travel safety improvement. One of the major issues to be addressed is the speed limit of motor vehicles and radar speed measurements. Moreover, road traffic rules impose the obligation to wear safety belts during driving, carrying children in car safety seats and they put a ban on drink driving as well as driving under the influence of other intoxicating substances that have a negative influence on the driver’s physical condition and driving skills. This study analyses changes in traffic rules and provides assessment of the way they affect road traffic safety in Poland. The study presents an analysis of the issues connected with road vehicle operation and safety of the passengers including: wearing safety seat belts, use of children car safety seats, vehicle lighting, speed limit. Such issues as the proposed changes in breathalyzer use and implementation of safety systems to provide road users with safety have been addressed.

Opis:: The study deals with the results of operational tests of gear oils used in a regional railway transport system. The character of the aging process and the impact of gear oil operation on the main factors determining further usability of gear oil have been defined on the basis of the results of carried out tests. It was proved that transport systems lack reliable convenient diagnostic methods for gear oil used during the process of operation. One of the criteria taken into consideration in decision-making is the period of oil change imposed by the gear manufacturer. The long process of oil application is accompanied by physicochemical changes, which cause degradation of its properties. This phenomenon is referred to as oil aging. This fact can cause loss of viscosity, increase in the amount of pollution, and in effect a decrease in the ability to provide a durable boundary film. The lubricating ability of oil decreases as well. An increase in the amount of pollution is caused by interaction of the collaborating friction elements and by pollutants coming from the gear environment. These changes are of permanent character and reflect the state of new characteristics referred to as operational characteristics. Gear oils have a certain lubricating ability, which is a critical parameter. This study is an attempt to find a way of the oil service life extension and convince the propulsion systems manufacturers that reduction of costs connected with rail vehicle maintenance does make sense.

Opis:: The article presents the results of laboratory tests of selected properties of fuels available on the market and fuels with higher density component B100 obtained from rapeseed oil (10, 30, 50 and 100%). An analysis of the cetane number, viscosity, and weight of the ash remaining after combustion of fuel samples was made. It was found that the cetane number of pure biocomponent is higher than diesel oil of mineral origin and it slowly decreased along with a decrease in the Extras component. All tested samples of fuels have appropriate cetane number to power internal combustion engines with compression ignition. The viscosity of the fuel samples measured at a temperature of 30ºC increased along with an increase in the content of biocomponent and approached the limit values for fuels. According to the results presented by other authors in their studies ash mass decreased along with an increase in the content of the component. Only premium diesel showed less ash mass than other fuel. The study includes also the energy value and the calorific value of liquid fuels with addition of a biocomponent, which power diesel engines. The results of the tests indicate a slight decrease in the calorific value of the fuel along with an increase in the content of biocomponent, which does not affect the ability to power the engines. Laboratory tests have proved that use of methyl esters of fatty acids in diesel fuel is the right choice to power diesel engines.
