Opis:
The life cycle cost (LCC) methodology provides understanding of economic aspects of urban buses equipped with different types of propulsion. The LCC analysis delivers the sum of costs related to the acquisition, operation, repair and maintenance disposal as well as the costs for the each bus power train technology. The method allows to take into account all costs for the whole vehicle’s life cycle and creates a precondition for precise information database for decision making. In addition to the economic factors LCC can be extended to environmental aspects such as greenhouse gases emissions. The environmental impacts of the vehicle lifetime may be presented in monetary values. The paper presents the Life Cycle Cost analysis undertaken for urban buses fitted with conventional, series hybrid and parallel hybrid drives. Provided LCC analysis includes the economic and environmental aspects. The paper also delivers the evaluation of the total air pollutant emissions for all stages of lifetime of the each analysed urban bus. The results show that the hybrids have slightly lower life cycle cost than conventional bus. Moreover, hybrid buses were found to have lower life cycle environmental impacts.

Opis:
Full electric (FEV) and plug-in hybrid (PHEV) vehicles are promising, forward-looking technologies to reduce greenhouse gas (GHG) emissions and other pollution related to road transport. The powertrain of a FEV is composed of a battery, control electronics and the electric motors. A PHEV has much lower battery capacity but it contains an extra internal combustion engine and gearbox. Many argue that FEVs are more energy-efficient than internal combustion engines. However, this energy needs to be stored in heavy, large-capacity battery packs that require plenty of energy and resources to produce as well as highly polluting rare earth elements mining. In this article, an environmental comparison of FEVs and PHEVs is shown using life cycle assessment (LCA). To make the comparison realistic, two models similar in size and power have been selected: Volkswagen E-Golf FEV and Volkswagen GTE PHEV. Results show that the production of FEVs need more energy and it means more burden on the environment however during the use phase it causes less emissions. Since the local electricity production mix and, in case of PHEVs, the user behaviour highly affects the results, three different countries (Hungary, Poland and Norway) and two different use types are considered. The quantified environmental footprints as well as the break-even distances are presented. Sensitivity of the results towards the assumed conditions during the whole design lifetime of the vehicles is discussed.

Opis:
To reduce air pollution and avoid petroleum exhaustion problem, many advanced countries, especially Japan installed Hybrid Vehicles (HV). As the use of HV popularizes around the world, there will be a huge amount of End-of-Life HV in the near future, and the proper treatment of these End-of-Life HVs, especially the waste NiMH (Nickel-Metal Hydride) batteries, will become a serious problem. Currently, the recycling of NiMH battery is gaining substantial attention. However, instead of recycling waste NiMH batteries directly, regenerating and reusing a used NiMH battery for a secondhand HV will largely reduce waste battery generation and demand for new NiMH battery. However, the environmental impact of regenerating and reusing a waste NiMH battery was not clear and has not been compared with the situation when using a brand-new NiMH battery. The purpose of this research is to compare the environmental performance (CO2 emission) of regenerated NiMH battery and brand-new NiMH battery in an HV from their production to usage stage and to discuss the validity of using a regenerated NiMH in Japan and in other countries using the Life-Cycle Assessment (LCA) approach. This research analyzed the composition of a NiMH battery and the CO2 emission during the manufacture, transportation, regeneration and usage process of a NiMH battery. The data used in this research was collected from reports and data published by the government of Japan, vehicle makers and previous studies. Original field survey and interview research on battery regeneration operators were also performed. The result showed that there is not a big difference in environmental effect. Moreover, by doing so, a huge amount of resource will be saved from battery manufacturing process while reducing waste generation. It is recommended that waste NiMH battery should be regenerated and reused in HV instead of being recycled directly in the future.

Opis:
The research aims to find an effective way to reduce real-world CO2 emissions of passenger vehicles, by answering the question of what kind of vehicles in various countries generates the smallest carbon footprint. Emissions were calculated for vehicles from three of the most popular segments: small, compact, and midsize, both with conventional body and SUVs. Each type of vehicle was analyzed with various types of powertrain: petrol ICE (internal combustion engine), diesel ICE, LPG ICE, petrol hybrid, LPG hybrid and BEV (battery electric vehicle) with four different carbon intensity of electric energy source. The final conclusion provides guidelines for environmentally responsible decision-making in terms of passenger vehicle choice.

Opis:
The life cycle assessment (LCA) method is a new analytical tool, which makes it possible to formulate quantitative description of the environmental impact of objects, services, and processes throughout their whole conventional period of existence. lt consists in identifying and quantifying the raw materials and energy consumed, pollutants emitted, and wastes generated and then evaluating their potential environmental effects. The possibility of applying the LCA approach to the analysis of environmental properties of motor vehicles has been examined in this paper. The basic methodological aspects of the life cycle assessment have been presented. Within the study, the environmental impact of a passenger car with a diesel engine was analysed. Most attention was devoted to the assumptions concerning the methods of vehicle use. To tackle this issue, two vehicle motion models representing the road conditions prevailing in Poland were developed. In one of them, the vehicle motion in urban, extra-urban, and high-speed traffic conditions was taken into account. The other model represented the traffic conditions typical for street congestions. These models were compared with the vehicle motion model built in the form of a vehicle speed program as adopted in the NEDC type-approval driving test. Based on the vehicle motion models and stochastic characteristics of pollutant emissions determined with the use of the Monte Carlo methods, the on-road pollutant emissions and fuel consumption were determined for the motor vehicle. The data obtained were used for describing the style of vehicle use within the life cycle assessment. The results obtained we re found to be very susceptible to the assumptions made.
Ocena cyklu istnienia jest narzędziem analitycznym umożliwiającym ilościowy opis oddziaływania na środowisko obiektów, usług i procesów w całym umownym okresie ich istnienia. Polega ona na identyfikacji i kwantyfikacji zużytych surowców i energii, emitowanych zanieczyszczeń oraz generowanych odpadów, a następnie ocenie potencjalnych skutków, jakie mogą wywołać w środowisku. W artykule rozważono możliwość zastosowania oceny cyklu istnienia do analizy właściwości ekologicznych samochodów. Przedstawiono jej podstawowe aspekty metodyczne. Dokonano analizy wpływu na środowisko samochodu osobowego z silnikiem o zapłonie samoczynnym. Najwięcej uwagi poświęcono założeniom dotyczącym sposobów użytkowania samochodu. W tym celu opracowano dwa modele ruchu samochodu reprezentujące warunki drogowe w Polsce. W pierwszym modelu uwzględniono ruch samochodu w miastach, poza miastami i na trasach szybkiego ruchu. Drugi model odpowiada warunkom ruchu typowym dla zatorów ulicznych. Utworzone modele zestawiono z modelem ruchu w postaci przebiegu prędkości w homologacyjnym teście jezdnym NEDC. Na podstawie modeli ruchu i stochastycznych charakterystyk emisji zanieczyszczeń utworzonych metodą Monte Carlo wyznaczono emisję drogową zanieczyszczeń i zużycie paliwa przez samochód. Uzyskane dane wykorzystano do opisu użytkowania samochodu w ocenie cyklu istnienia. Stwierdzono znaczną wrażliwość otrzymanych wyników na przyjęte założenia.
