    Opis:
    The article presents selected aspects related to the influence of toxic components of exhaust gases from vehicle transport vehicles on environmental pollution and human health. The paper describes the quantitative structure of motor vehicles that are operating in Poland. The structure of used passenger cars that were imported from abroad and first registered in Poland was presented. The procedure for periodic control tests in exhaust emission diagnostic stations is also described. The results of the study allowed to distinguish a group of vehicles that did not meet the limits of pollution established by the legislator.

    Opis:
    New test procedures for determining exhaust emission from passenger vehicles will be introduced in 2017. For several years, the European Commission has been developing new procedures, which aim is to perform tests in road conditions. The purpose is to determine the real values of emissions, which are not always reflected by the level of emissions obtained in the laboratory. Proper and accurate procedures for determining emissions in real traffic conditions (RDE – Real Driving Emission) have not yet been approved (as opposed to Heavy Duty Vehicles for which such conditions already exist), but there are proposals that are currently being analyzed by major research centers in Europe. There are many differences between those proposals such as determining road emission or research methodology related to emission measurement of hydrocarbons. The work compares the results of emissions measured in road tests using the latest legislative proposals related to passenger cars. The results are shown in relation to the used measurement method: classic method of determining exhaust emission; uses all measurement data determining the mass of harmful compounds and distance travelled during the test; method of averaging the measuring windows (MAW – moving average windows), also in the literature called EMROAD method, which determines the measurement windows (on the basis of carbon dioxide emissions from the WLTC test) and on its basis determines the road emission in RDE test; generalized method of instantaneous power (Power Binning), known in the literature as CLEAR – Classification of Emissions from Automobiles in Real driving, determines road emissions on the basis of generalized instantaneous power during the RDE test.

    Opis:
    W artykule przedstawiono wstępną koncepcję opracowania testu badawczego wykorzystywanego w pomiarach emisji spalin w rzeczywistych warunkach ruchu dla pojazdów osobowych. Podstawą podjęcia pracy był brak rozwiązań prawnych, dotyczących określania poziomu ekologiczności pojazdów lekkich – w przeciwieństwie do pojazdów ciężkich, dla których takie regulacje już określono. Podstawą opracowania będzie porównanie testów emisyjnych wykorzystywanych w badaniach homologacyjnych samochodów osobowych, a jednocześnie synteza wyników uzyskanych w różnych warunkach badań drogowych. Zamierzeniem jest opracowanie testu, umożliwiającego ocenę ekologiczną pojazdu w rzeczywistych warunkach ruchu, gdzie ograniczeniami będzie tylko rodzaj napędu (silnik ZI, ZS, pojazd hybrydowy), co jest zgodne z wymaganiami badań homologacyjnych. Efektem powinny być założenia do opracowania testu pod względem: czasu trwania, określenia warunków pracy silnika i pojazdu oraz propozycji dopuszczalnych wartości emisji spalin.
    This paper presents the preliminary concept research to develop the test used in the measurement of emissions in real traffic conditions for passenger vehicles. Work based on the lack of legal solutions for determining the environmental performance of light vehicles – as opposed to heavy-duty vehicles for which such regulations have specified. The elaboration is to compare the emission test used in clinical approval of passenger cars, while the synthesis of the results obtained under different conditions road tests. The intention is to develop a test for assessing the ecological vehicle in real traffic conditions, where restrictions will only drive type (gasoline engine, diesel engine, hybrid vehicle), which is consistent with the requirements of the certification tests. The result should be the foundation for the development of the test in terms of: the duration, to determine the operating conditions and vehicle and proposals for emission limit values.

    Opis:
    Priorytetem działań Unii Europejskiej na rzecz ochrony środowiska jest ocena emisji zanieczyszczeń w rzeczywistych warunkach ruchu pojazdów. Procedury takiej oceny opracowano dla pojazdów ciężkich i pojazdów pozadrogowych, natomiast brak jest unormować prawnych takiej oceny dla pojazdów lekkich (samochodów osobowych). W związku z tym, w artykule podano propozycję metodyki opracowania testów kontrolnych badań emisji zanieczyszczeń z samochodów osobowych. Do analizy wybrano samochody osobowe o napędzie hybrydowym, gdyż jest to najszybciej rozwijająca się grupa pojazdów o największych walorach ekologicznych, a jednocześnie najmniejszym przebiegowym zużyciu paliwa, spełniająca najnowsze normy emisji spalin. Według autorów koncepcja opracowania testów dla samochodów osobowych powinna opierać się następujących przesłankach: wyznaczeniu spójnego obszaru pracy silnika dla wybranych pojazdów osobowych, w taki sposób, aby w największym stopniu odpowiadał najczęstszym warunkom ruchu oraz określeniu parametrów mierzonych pod-czas testów drogowych i uzyskiwanych wskaźnikach emisji. W artykule przedstawiono procedurę wyznaczenia warunków pracy silników spalinowych, co w efekcie umożliwiło zaproponowanie testu RDE dla samochodów osobowych o napędzie hybrydowym.
    The priority of the European Union operation is protecting the environment by evaluating emissions under real operating conditions. The procedures have been developed for the assessment of heavy vehicles and off-road vehicles, however there is no legal rules for such evaluation for light vehicles (passenger cars). The article contains, proposal for develop a test methodology for control of emissions from passenger cars. Hybrid vehicle was selected for analysis, because it is the fastest growing group of vehicles with the highest ecological value, while the smallest fuel consumption that meets the latest emission standards. The concept of designation of the road test for passenger cars should be based on the following considerations: the appointment of a consistent engine operating range for selected cars, in such a way that the greatest corresponded most frequent in real conditions and the parameters measured during the road test and obtained emission factors. The paper presents a procedure for the designation of the operating conditions of internal combustion engines, which enabled to propose RDE test for hybrid vehicles.

    Opis:
    Major markets across the European Union (EU) are concentrated on rapid development of electromobility. This policy is demonstrated - among others - by recent sales of electric cars: within the past 3 quarters of 2018 - 24.7 thousand electric cars have been registered in Germany, 20.3 thousand in France, 15.3 thousand in the Netherlands and 31.4 thousand in Norway. Unfortunately, only 867 EVs have been registered in Hungary, 469 in the Czech Republic, 468 in Romania, 411 in Poland and 348 in Slovenia. Unit energy consumption of electric cars was often defined in NEDC cycle. In real conditions of road traffic, it may differ from values recorded in a drive cycle. The article presents results of a study on energy consumption of electric cars in Poland along RDE (Real Driving Emissions) testing route in terms of vehicle energy consumption per drive unit (km, 100 km). The use of fuel cells in cars may bring a change in the type of used vehicles in the long run. Both globally and in the EU wide-ranging actions are undertaken to implement fuel cell technology. Also, the infrastructure of hydrogen filling stations is developed. At present the most rapidly developing country in this area is Japan. The article addresses the issue of energy consumption per drive unit by cars equipped with fuel cells as both type of vehicles, i.e. EV and FCV use electric motors. The article also discusses infrastructure development in the EU and Poland, charging and fuelling of the said vehicles, respectively.

    Opis:
    In the regulations concerning approval of light vehicles starting from September 2019 it will be necessary to conduct exhaust emissions tests both on a chassis dynamometer and for real driving emissions. It is a legislative requirement set forth in EU regulations for the purpose of the RDE (Real Driving Emissions) procedure. To decide on the RDE route for the purpose of the LV exhaust emissions tests many requirements must be fulfilled, regarding for example external temperature and the topographic height of the tests, driving style (driving dynamic parameters), trip duration, length of respective test sections (urban, rural, motorway, etc.). The works on outlining RDE routes are continued across the country in various research centres. Specifying the RDE route for test purposes, i.e. works in which the authors of this article are actively involved, has become a major challenge for future approval surveys concerning the assessment of hazardous emissions from light vehicles and for development studies focusing on - for example - the consumption of energy in electric and hybrid vehicles. The test route has been chosen to ensure that the test is performed on a continual basis. Data were recorded on a constant basis with the minimum duration of the test achieved. The test involved light vehicles and PEMS device for measuring the exhaust emissions, vehicle’s speed, completed route, etc. The device was installed in such manner as to ensure that its impact on the exhaust emissions from the tested vehicle and on the device’s operation is the least. The vehicle load was consistent with the requirements of the standard and included the aforesaid measurement device, the driver and the operator of PEMS. The tests were carried out on working days. The streets and roads used for the tests were hard-surfaced. Measurements were performed in accordance with the requirements of RDE packages (Package 1-4), i.e. taking into account - among others - the engine cold start. The article discusses the method of outlining the test route fulfilling the specific requirements for RDE testing. Chosen results of exhaust emissions from a passenger car with a spark-ignition engine along the defined RDE test route have been provided. The tests discussed in the article are introductory in the area of RDE tests and provide an introduction into further studies of exhaust emissions and energy consumption in real driving conditions in conventional vehicles and vehicles with alternative engines, e.g. hybrid and electric vehicles.

    Opis:
    Modernization of passenger cars and constant development of existing legislation lead to a reduction of exhaust emissions from these vehicles. In accordance with package 3 of the RDE test procedure, the European Commission has extended testing methods by including exhaust emissions during a cold start. The article compares the research results on the impact of ambient temperature during the cold start of spark-ignition and compression-ignition engines in road emission tests. The tests were carried out in line with the requirements of the RDE test procedure for passenger cars meeting the Euro 6d-Temp emissions standard. The obtained results were analyzed, i.e. there were compared the engine and vehicle operation parameters and the values of road exhaust emissions, during the cold start of gasoline and diesel engines at the ambient temperature of approximately 25°C. The summary presents the share of cold start phase of a passenger car (at the ambient temperature of around 25°C) for each exhaust emission compound in the urban part of the test, and in the entire RDE test, depending on the engine type used.

    Opis:
    The article compares driving test data using the latest legislative proposals applicable to passenger cars with different drives. For this purpose, cars of one type were selected, meeting the same exhaust toxicity standard (Euro 6c) and differing in used internal combustion engines (with spark-ignition, compression-ignition and hybrid drive). Several measurements were performed on the same test route in accordance with the RDE test guidelines, which requires a several of criteria to be met. These criteria include the length of the measuring sections, their overall timeshare and the dynamic characteristics of the drive. A portable emissions measurement system (PEMS) was used to record the engine and vehicle operating parameters and to measure the exhaust emissions during tests. This allowed for the monitoring of parameters such as: load value, engine speed and vehicle velocity. Then the obtained results were analyzed for their compatibility with the RDE procedure requirements. By determining the road emission of individual harmful compounds for all vehicles and the dynamic parameters of drive (relative positive acceleration and product of speed and positive acceleration) in various phases of the road test it was possible to compare them. On this basis, the impact of dynamic conditions of road tests on the obtained results of the road exhaust emission of harmful compounds for passenger cars with various drives was defined.

    The article compares data obtained in road tests with the latest legislative proposals relating to various applications of internal combustion engines. Passenger car emission tests have been performed several times on the same test route in accordance with the RDE procedure guidelines, for which a dozen or so criteria must be met, including the distance of each of the drive sections, their in the drive time and the dynamic characteristics of the drive. The analysis was also based on a two-dimensional operating density characterization, presented in the vehicle speed-acceleration coordinates. As a result, it was possible to compare dynamic properties, operating time density and, thus, to check the validity of conducted drive tests in terms of their feasibility and emission values. An exhaust emission related comparison of three types of powertrain have been presented: gasoline, diesel and hybrid in the RDE tests. The authors proposed a new form of presenting the road exhaust emissions results in relation to the carbon dioxide emission, referred to as a standardization of the emission results. The exhaust emissions from city buses fitted with different powertrains tested on an actual bus route and in the SORT test were also compared.

    As awareness regarding ecology increases among drivers, some characteristics of electric vehicles mean that they attract a greater interest. The basic factors determining the demand for electric cars include their pricing, access to charging stations and the cost per 1 kWh. Considering the above, the aim of this paper is to review the current areas of research into renewable energy sources, such as wind and solar energy and energy derived from vertical displacements of the car body associated with road roughness. The use of such solutions will allow the battery to be charged while the vehicle is in motion and extend the time of travel without stopping the vehicle for charging. The publication forms an overview of findings in the area and the scope of the research reported here relate to the most recent research. For this purpose, reviews of academic and industrial literature were carried out.
