Compact Portable Emission Measurement Systems
PEMS (Portable Emission Measurement System) / RDE (Real Driving Emissions)
The device fitted on the test vehicle hardware includes flue gas analyzers, exhaust gas mass flow meter, a weather station a GPS system and the connection to the vehicle network for constituent evaluation.
A probe delivers the vehicle exhaust gases from the test box in real-time mode. The component emissions (CO, CO2, NOX [oder NO + NO2]) together with the associated engine, vehicle and environmental parameters are then recorded for analysis.
PEMS Application Examples
- Measurement and analysis of the exhaust emissions directly from the vehicle, while on an actual road trip
- Fuel consumption measurement
- Analysis for engine development and exhaust after-treatment
- Component testing
