    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:
    Occupants protection during vehicle crash is one of the major problems considered at vehicle designing stage. The increasing safety as well as comfort requirements results in the total vehicle weight increase. On the other hand, higher mass influence on the fuel economy of vehicle. Thus, it is very important to maintain or even reduce vehicle weight. One of the solutions of this problem is application of a new materials having good strength-to-weight ratio i.e. high strength steels (HSS). They are often used in protective and energy absorbing structures in automotive industry. One of HSS so-called austenitic steels are characterized by excellent mechanical properties such as: high strength, strong strain, and strain rate hardening. Those mechanical effects are consequence of microstructural evolution during strong deformations i.e. twinning and phase transformation. As a consequence those steels are very good material for the purposes of energy absorbing and protective structures. This article presents the results of mechanical properties tests of VP159 austenitic steel. On the basis of experimental data, the JC constitutive model has been calibrated. The obtained results were used for the computer simulations of energy absorbing of square profiles made of analysed material. The results were compared with other types of steel.

    Opis:
    This article concerns the issue of reduction of CO2 emission in hybrid vehicles. External lighting through LED technology was applied to show additional CO2 savings in these vehicles. The authors propose for hybrid vehicles of M1 category: conditions of testing external lights, research equipment with measuring system and measuring method in order to determine energy savings obtained by application of external LED light. It enables to calculate saving of CO2 emission and estimate potential energy and ecological benefits. Computational formulas of CO2 emission savings and calculated fuel consumption and percentage reduction of CO2 proposed by the authors were used as a confirmation. Average worktime of lighting and three configurations of sources of lighting of hybrid vehicles were used in the analysis: halogen bulb/bulb, xenon/LED lamp and full electroluminescent external lighting.

    Opis:
    Vehicle operating fuel consumption estimation has a measurable significance for both individual users as well as transport and Communications companies. Complex analysis of the results may cause reduction of power (fuel) consumption, CO2 and toxic compounds emissions in exhaust gases. Operating fuel consumption estimation carried out by drivers' encounters basic difficulties connected with the lach of reliable reference standard for comparison of measured fuel consumption during car usage. Therefore it is necessary to identify vehicle operating conditions and ascribe them reference fuel consumption according to the accepted reference standard. A method of description ofreal vehicle operating conditions has been presented in this paper. Presented examples show that vehicle operating conditions may be unambiguously described with the use of proposed indicators. They can be also used to forecast the fuel consumption with high accuracy. Exclusive use of certification tests as model of operating conditions for this purpose does not allow keeping high conformity of assumptions with usage practice. Creation ofan individual map of operating conditions for a chosen agglomeration would enable to optimize choice of vehicle or fleet for an intended place of operation. Utilization of such operating conditions map may be: to determine reference fuel consumption for assumed operation area or optimal route of drive from the point of view of minimizing fuel consumption, energy or CO2 emission to the atmosphere. Selected examples of Utilization of such operating conditions map have been presented.

    Opis:
    The total CO2 emission of electric vehicle depends on a renewable energy share in an energy market of given country. At the moment, this share is significant only in a few European countries (Denmark, Germany, Scandinavian countries) having large number of water, solar and wind power plants. Additionally, France may be considered as a country possessing low-emission electric energy, because around 90% of this energy is generated by a nuclear power plants. In order to compare the greenhouse gas emission from an electric vehicle with combustion powered cars well-to-wheel (WtW) methodology may be applied. The well-to-wheel emission estimates the total CO2 which is required to generate a given power measured on vehicle wheels including generating, transferring and processing losses. The magnitude of WtW varies from 0g/km in the case of a vehicle charged directly by a solar or wind powered charging point to 200 g/km in the case of charging form public grid powered by old coal power plants. For the Polish energy market the share of renewable energy sources is negligible (below 10%), moreover majority of a power plants uses coal to generate electricity. However, according to the EU strategy this share should be doubled until 2020. Additionally, it is considered building of a nuclear power plant, which results in further reduction of CO2 from energetic industry. In this article WtW CO2 emission of electric driven vehicle charged from the public grid was analyzed for Polish conditions at present and various growth scenario as well. Moreover, an actual energy market structure as well as growth perspectives were reviewed.

    Opis:
    The Well-to-Wheel (WtW) CO2 emission of the electric vehicle (EV) strictly depends on amount of a carbon dioxide (including transmission and conversion losses) required to produce an electric energy used to charge EV batteries. Value of the WtW emission may be lowered by increasing a share of low-pollutant power plants i.e. using renewable energy or nuclear power, however it needs a large financial investments and it is very long process, taking over a dozen years. Even in the case of countries having a large share of low-emission power plants (Germany), a smart grids must be applied in order to optimize a value of WtW CO2 emission. Usually batteries are charged during night, where energy demands are relatively low and at the same time wind turbines supplies majority of electric energy to the grid. Presented idea of the battery charging station described in this article has a local character. It uses photovoltaic panels as a source of "green" electric energy. As a consequence the value of WtW emission for an EV batteries charged in this station equals to 0 g/km. The charging station uses EV battery swap thus the time of staying in the station is shorter in comparison with normal or even fast charging. The battery swapping technology uses replacing of the discharged units mounted in EV by fully charged ones. The batteries are placed in special try, which enables a quick mechanical and electrical connecting and disconnecting. Moreover, batteries stored in the station may be used as an energy storage devices and makes charging process optimization easier; moreover, they can be used as an element of a smart grid system. The article describes model of charging station using both photovoltaic and quick EV battery swap.

    The article presents calculations of exhaust emissions and fuel consumption under test conditions on a chassis dynamometer test bench. The study describes the realization of the tests and the methodology of the calculation of the exhaust gas flow and the estimation of the fuel consumption based on exhaust emissions. The presented research results and their analysis describe the emission scale of selected gaseous fumes components during full engine load and the fuel consumption associated with such tests. Similar emissions occur during a rapid acceleration of a vehicle in road conditions.
