EMPIR Project 19ENV09

Improved vehicle exhaust quantification by
portable emission measurement systems metrology (MetroPEMS)

A Joint Research Project within the European Metrology Research Programme EMPIR.


Nitrogen Oxides (NOx) and fine particles emitted from cars are the leading causes of air pollution. In recognition of this, EC legislation was recently introduced for on-road type approval (TA) real driving emission (RDE) tests using portable emissions measurement systems (PEMS), however metrological validation is lacking. In order to support the accuracy and comparability of vehicle emission values, procedures for metrological PEMS characterisation (for NOx, particle number (PN) and exhaust gas flow) and the development of the associated infrastructure are required. This is particularly relevant for the accurate verification of vehicle emission limits in TA, and thus vital for (i) European vehicle manufacturers, (ii) the associated measurement device industries and (iii) the legislative bodies responsible for ensuring adequate air quality despite increasing traffic emissions.

The overall goal of the MetroPEMS project is to develop calibration methods and the support infrastructure for PEMS validation and TA RDE tests to meet existing and upcoming regulation in the EU for the challenging pollutants NOx/NO2 and PN. The project is structured in 6 work packages. More details can be found here.
