    Real Driving Emissions
    Opis:
    This paper presents the results of tests conducted in real traffic conditions in a mountainous area, taking into account the natural topography characteristics. The tested vehicle was of SUV type (Sport Utility Vehicle) with gasoline and Diesel engine, complying with emission standard Euro 5. Using the portable system for measurement of harmful substances, measurements of pollution emissions were conducted. The results obtained confirmed the substantial changes in the emission of harmful components of exhaust fumes with the change of the road grade. In all considered cases, it was confirmed that with the increasing route grade, the road emissions of all harmful components of exhaust fumes increase, however this increase varies for different pollutants. The most sensitive for spark ignition engines is emission of particulate matter, which is associated mainly with the compression ignition engines. For small changes of the road grade, the most sensitive seems to be road emission of carbon monoxide, for gasoline engines emission of particulate matter is specific, first, to all diesel engines, increase of the road grade to 10% caused on average twofold increase in the emission of harmful components of exhaust gases.

    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.

    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:
    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.

    Real Driving Emissions
    Opis:
    In the assumptions, regarding to the transport policy both at the level of country and Europe there is the concept of sustainable development of transport. Warsaw University of Technology in cooperation with Poznan University of Technology performs research work concerning the shaping of environmentally friendly transport system – Project EMITRANSYS. In this project, one of the conditions is to reduce exhaust emissions by means of transport. The paper presents the reasons for the testing of the exhaust emissions under Real Driving Emissions testing (RDE). Research potential of Institute of Combustion Engines and Transport at Poznan University of Technology in the area of road testing of passenger and heavy-duty vehicles has been presented in the paper. Example test results have been shown in the aspect of the emission-related classification of vehicles. The major challenge of worldwide emission standards, engine operating parameters in various emissions tests, the test potential under real operating conditions, the view of the analyser for on-road emission testing of vehicles, the test results for road emission of CO, HC and NOx, detailed characteristics of the averaged particle number for the entire test run (vehicles with different mileage and different emission class) for: Euro 4 class and 75,000 km; Euro 4 class and 500,000 km; Euro 5 class and 75,000 km; Euro 5 class and 500,000 km are presented in the paper.
