PEMS (Portable Emission Measurement System)
The Exhaust Emissions Test in Road Traffic
At the DEKRA Test Center in Klettwitz, we use the PEMS (portable emission measurement system) technology for this - a mobile exhaust emission measuring device for real operations. To determine the emissions on public roads using PEMS, the RDE (real driving emissions) process is additionally applied. For the RDE test, the vehicles are equipped with the PEMS technology for mobile emission measurement and are tested with respect to the nitrogen oxide (NOx), carbon monoxide (CO), and particle number (PN) limits on a roller dynamometer in the DEKRA Test Oval and in real road traffic. Even during the journey, precise measurement data is collected thanks to the exhaust emission measuring device at the rear of the vehicle as well as various sensors, allowing an exact link between the driving situation and the exhaust emissions result to be ascertained.
Our DEKRA experts possess many years of extensive knowledge relating to mobile emission measurement on vehicles at our DEKRA Test Center. Here, our services and experience relate not to conventional vehicles alone, but also to hybrid drives.
We are pleased you are interested in our PEMS process. We will be happy to put together an individual offer for you.
