Testing and evaluation of cold-start emissions in a real driving emissions test

Transportation Research, Part D: Transport and Environment, 2020
Abstract 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), 2019
Although 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 ...

Condensation of Real-World Drive Cycle into Synthetic Drive Cycle - An Innovative Method to Predict Real Driving Emissions

SAE Technical Paper Series, 2021
<div class="section abstract"><div class="htmlview paragraph">The stringent emission regulations have put enormous pressure on auto manufacturers to develop vehicles with the required conformity factor (CF) on real driving emissions (RDE). However, evaluation of CF on multiple and varying real-world cycles by portable emission measurement ...

Efficient Monitoring of Real Driving Emissions

2018
The 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

2017
Die 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.
