Testing and evaluation of cold-start emissions in a real driving emissions test
Transportation Research, Part D: Transport and Environment, 2020Abstract To properly evaluate the cold-start emissions of vehicles, four light-duty vehicles were selected to complete a Real Driving Emissions (RDE) test. The analysis and evaluation of the RDE test results reveal that the cold-start emissions account for a significant proportion of the urban trip emissions, and that the moving average window (MAW ...

The regression model of NOx emission in a real driving automobile
2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2019Although the Portable Emission Measurement System (PEMS) has become the official certification procedure for vehicles, but it is very expensive and cannot be used as a monitoring device for massive use. The purpose of this study is to establish a low-cost vehicle pollution monitoring system (NGK NOx sensor, Arduino with CanBus) and uses this system to ...

Efficient Monitoring of Real Driving Emissions
2018The diesel emissions scandal has demonstrated that real-world behavior of systems can deviate excessively from the behavior shown under certification conditions. In response to the massive revelation of fraudulent behavior programmed inside diesel cars across Europe, the European Union has defined a procedure to test for Real Driving Emissions (RDE ...

vRDE – Virtual Real Driving Emission
2017Die Verbrauchs- und Emissionszertifizierung anhand des NEFZ stand bis zuletzt, nicht nur im Zusammenhang mit den sogenannten „Defeat Devices“, in scharfer Kritik – 2017 soll mit der Einfuhrung von WLTP und RDE genau diese Problematik aufgegriffen werden. Europa ubernimmt damit eine Pionierrolle auf dem Gebiet der Emissionsgesetzgebung.

Questions about Real Driving Emissions in Brazil
SAE Technical Paper Series, 2017<div class="section abstract"><div class="htmlview paragraph">The motor vehicles are the main source of atmospheric pollution, especially carbon monoxide, hydrocarbons and nitrogen oxides (NOx). To reduce these emissions for environmentally acceptable levels, Europe and the United States have developed control programs, where are set ...

Diesel vehicle emissions generally deteriorate with vehicle mileage due to the wear and deterioration of vehicle parts. Most of the experimental studies on vehicle emission durability were carried out based on the standard operation cycles of engine or vehicle, few research investigated vehicle emission deterioration characteristics under real driving ...

From laboratory to road – Real Driving Emissions
2016In European emission type approval during the past years the exhaust emission limits have been reduced significantly. Although air quality was improved from 1990 on, a high percentage of the European population is exposed to air pollutant concentrations above European limit values, mainly on particles, nitrogen dioxide (NO2) and ozone (O3).
