    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.

    W artykule zaprezentowano wyniki pomiarów toksyczności spalin samochodu dostawczego w rzeczywistych warunkach ruchu. Celem badań było zweryfikowanie wpływu stylu jazdy kierowcy na emisję substancji szkodliwych w spalinach. Do realizacji celu wykonano pomiary emisji drogowej podstawowych gazowych związków toksycznych w spalinach emitowanych do atmosfery przez jednostkę napędową pojazdu. Do pomiarów zawartości poszczególnych zanieczyszczeń gazowych wykorzystano mobilną aparaturę do badań toksyczności spalin typu PEMS.
    The article presents the results of measurements of exhaust emissions of commercial vehicle in real traffic conditions. The aim of this study was to determine how the driving style effects on the exhaust emissions from vehicle engine. The determinants were the measurements of the concentration of main toxic substances emitted to the atmosphere from the power unit of the tested vehicle. In the measurements a portable exhaust emission analyzer was used (PEMS type).

    The article presents the results of measurements of exhaust emissions of commercial vehicle in real traffic conditions. The aim of this study was to initial verification how the driving style affects on the exhaust emissions from vehicle engine and fuel consumption. The determinants were the measurements of the concentration of CO2 and others harmful substances emitted to the atmosphere from the power unit of the tested vehicle. In the measurements a portable exhaust emission analyzer was used (PEMS type).

Celem badań było wstępne zweryfikowanie wpływu stylu jazdy kierowcy na emisję substancji szkodliwych w spalinach oraz zużycie paliwa przez pojazd. Do realizacji celu wykonano pomiary emisji drogowej dwutlenku węgla i innych związków szkodliwych spalin emitowanych do atmosfery przez jednostkę napędową pojazdu. Do pomiarów zawartości poszczególnych zanieczyszczeń gazowych w spalinach wykorzystano mobilną aparaturę do badań toksyczności spalin typu PEMS.

    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.

    Opis:
    Among the fundamental factors affecting the emissions of internal combustion engines is the resistance to motion acting on the car. This is an important factor to be taken into account when testing cars in conditions simulated on a chassis dynamometer. The dependence of the driving resistance function on vehicle speed is determined on the basis of various methods, the most frequently used of which is the so-called alternative method specified in procedures for the type approval of motor vehicles with respect to the emission of pollutants in exhaust gases. The values adopted in accordance with the alternative method differ from the actual resistance acting on the car in road conditions. This is one of the reasons why the emission of pollutants and the fuel consumption of an engine in real road conditions differs from the values given by the car manufacturer, including the emission limits specified in the standards. This paper presents an evaluation of the influence of driving resistance on the energy demand and emission of pollutants in the exhaust gases by sample passenger car with SI engine fuelled by petrol and LPG.

    Opis:
    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.
