Opis:
Posiadając dane ilościowe i jakościowe, podjęto próbę zbadania zależności i związków zachodzących między rozwojem transportu a efektywnością wykorzystania zasobów paliwowych, co stanowiło zasadniczy cel artykułu. Przeprowadzona analiza pozwoliła stwierdzić, że transport drogowy zyskał obecnie szczególny status w życiu codziennym społeczeństwa. Wzrost mobilności mieszkańców Europy spowodował, że samochody osobowe są aktualnie w największym stopniu odpowiedzialne za potrzeby energetyczne transportu drogowego. Stało się tak mimo poprawy efektywności energetycznej tych samochodów oraz wzrostu przewozów towarowych. Prognozowany wzrost przewozów towarowych spowoduje dalsze zmiany w strukturze zużycia energii przez transport samochodowy. Poprawa efektywności energetycznej transportu osobowego i ciężarowego nie zrównoważy wzrostu zapotrzebowania na energię w transporcie drogowym. Przedstawione powyżej prawidłowości wyznaczają kluczowe wyzwanie stojące przed systemem transportowym – sprostanie ciągle rosnącemu zapotrzebowaniu na energię.
With quantitative and qualitative data, and knowing, at a glance, goal, it was an attempt to examine the relationship between the development of road transport and the efficiency of resource use. The analysis has shown that road transport now gained a special status in people’s daily lives. The increased mobility of European citizens caused the greatest responsibility for the transport of energy. This spite of improving the efficiency of these cars and freight transport growth. The projected continued growth of freight transport will contribute to the further changes in the structure of energy consumption by road transport. Despite the high growth rate of energy efficiency improvement of truck drives, the share of demand for fuel by those vehicles will increase in total fuel demand for road transport sector. At the same time the energy consumption of cars will reduce its share in total fuel needs transport. Improvmrnt of energy efficiency of passenger and truck will not offset the increase in demand for energy in road transport. The above regularities define a key challenge facing the transport system – meeting the ever growing demand for energy.

Opis:
For the third time in the history of humankind, it is trying to implement e-mobility. There is a reasonable hope that this attempt will succeed this time. E-mobility is generally regarded as a zero emission. This sentence can only be true in a very small scope, as only in relation to selected parameters and in a very limited its dimension. The situation can change radically. If it will be take into account, the emissions in the production of electricity is necessary for the movement of this type of vehicles Second problem is the energy use amount. We know today that the energy consumption of electric cars, especially in long-term operation is too big. This general knowledge is not confirmed by research results. Both relevant databases and methods of their analysis are missing. This is an unfavourable situation because it is not possible to verify the effects of various changes introduced e.g. in the construction or technology of cars. This publication can be included in those in which it is shown how to change this situation. The analysis of the results of long-term car use can be used as a verification of various development works, especially in e-mobility, which is only just starting. In the future, it will be need to create the appropriate “big data” databases and a number of tools to analyse the data collected there.

Opis:
Regenerative braking in electric or hybrid driven vehicles is now commonly used feature. Development of technologies of electrical machines, secondary energy sources, power electronics and control systems allows for more efficient using of this attribute. Regenerative braking system converts the kinetic energy of moving vehicles on this form of energy that you can store in a secondary source of energy. The most common form of energy after conversion is electricity, easy to store in batteries or supercapacitors. There also are known systems with storage of mechanical energy (high-speed flywheels with composite rotors). Drive systems with optional regenerative braking should take into account a number of aspects influencing the process. It is very important to maintain the stability of the vehicle movement during braking. Another important aspect is the cooperation of regenerative braking system with conventional, mechanical brake system of the vehicle driven by a single axis. Sizing of the electrical machine (or machines) is associated with the needs of the propulsion of the vehicle, which limits the amount of absorbed energy in the initial stage of braking. Individual elements of the system energy conversion efficiency chain complexity affect the energetic results of this process. On the energy, efficiency of the process of braking energy recovery affects string conversion efficiency in the individual components of the system. Regenerative braking is the important factor, which could improve electric vehicle market chances, particularly in the city or neighbourhood personal transport. The article contains a description of the technical and legal circumstances of the process of regenerative braking and energy aspects of this process.

Opis:
One of the most important elements determining the assessment of the quality of trolleybuses and buses in public transport is the operating cost which comprises mainly the cost of power or fuel consumption. The knowledge of economic properties of new vehicles is justified when the decision about their purchase is being made. The information about vehicles which have not been used in the company so far comes mainly from the protocols of homologation tests as well as the opinions of other users. In both cases such knowledge is insufficient against the expected information providing for specific driving conditions in urban traffic. Chosen driving tests applied for the evaluation of energy consumption of trolleybuses and buses operation are presented in the article. Working conditions of the trolleybus were analysed on the basis of the comparative tests of the bus and the trolleybus for a chosen communication line in Lublin. On the basis of the determined characteristics describing working conditions of the vehicles constituting public transport in Lublin, the MPKPL test was drawn up and the analysis of findings was carried out for a chosen communication line.

This manuscript is focused on the matter concerning the emissions of the greenhouse gases produced by the road freight transport mode. Those emissions influence the ozone layer structure and help to create the greenhouse impact causing the global warming, i.e. issues particularly related to the weather change aspects as well as extreme weather occurrences. In the first part of the paper, the calculation approaches, energy consumption examination as well as evaluation of emissions of the greenhouse gases created by the transport modes operation are performed by the EN 16258:2013 standard. The research chapter outlines the implementation of the approach technique to particular consignment on a specific transport section, while the sum of the energy consumption and greenhouse gases emissions production per pallet of goods weighing 1000 kg is specified. The resulting values form the fundamentals for declarations of energy consumption and greenhouse gas emissions. The proper and precise examinations of energy consumption and emissions production can help to identify the share of external costs for specific transport modes quite accurately. This ensures that such costs are fairly carried by the individual producers thereof.

Opis:
This study characterizes the distribution chain of liquefied natural gas (LNG) in Poland, using the terminal in Świnoujście as the “source of LNG”. The focus is primarily on the possibility of LNG distribution for road transport, taking into account the effective use of its energy potential. During the transport and storage of LNG it was found that the evaporation of LNG, the so-called boil-off gas (BOG), is a significant problem that leads to an increased pressure in the tank. Therefore, the possibility of using BOG in individual links of the LNG supply chain is indicated. One prospect is its compression to high pressure, which produces compressed natural gas (CNG) fuels. Thus, this paper specifies the influence of the initial BOG gas pressure on the unit compression work and analyses the change in the compression unit work, which depends on the final CNG fuel pressure, with a specific assumption for the BOG pressure.
