Speciation of nitrogen compounds in the tailpipe emissions from a SI car under real world driving conditions. [PDF]
, 2014 The tailpipe exhaust emissions were measured using a EURO4 emissions compliant SI car equipped with on-board measurement systems such as a FTIR system for gaseous emission, a differential GPS for velocity, altitude and position, thermal couples for ...

Assessment of real driving emissions via portable emission measurement system [PDF]
IOP Conference Series: Materials Science and Engineering, 2017 The European Commission approved a so-called Real Driving Emission (RDE) test in response to the criticisms to the current driving cycle used at chassis dyno for homologation purpose (NEDC): it is considered outdated and misleading since air pollutants in real driving conditions are considerably higher than the certification thresholds.

Machine Learning Applied to the NOx Prediction of Diesel Vehicle under Real Driving Cycle
Applied Sciences, 2021 Euro 6 standards impose stringent nitrogen oxide (NOx) emission limits on diesel cars. NOx emissions are significantly different between Euro 6 diesel cars and the previous standards in real-world driving. In this research, the NOx concentrations of Euro
