Summary

Although type-approval emission requirements for motor vehicles have been tightened significantly a high percentage of the population is exposed to air pollutant concentrations above EU limit values. Exhaust emissions of passenger cars and light duty trucks in Europe are measured by using the “New European Driving Cycle” (NEDC) under well defined ambient conditions in a laboratory. In addition Commission Regulations (EU) 2016/427 and (EU) 2016/646 establish the measurement of Real Driving Emissions (RDE) within European legislation. Exhaust emissions are measured in real traffic by using Portable Emission Measurement Systems (PEMS). Due to European air quality regulations NO_x emissions and particle number are the main issue of RDE. In order to allow a gradually adaptation of RDE requirements during a transitional period the test procedure is applied for monitoring purposes only. Due to the fact that RDE are measured in real traffic, this new method is challenging for all parties involved. During this presentation experiences with operating PEMS measurements, test results of the monitoring phase and the current status of RDE discussion are introduced.
