Non-exhaust emissions in general and brake particle emissions in particular have become very relevant during the last years. Even if many investigations and efforts are under progress, no common test standards exist so far. Many mechanisms and possible impacts are not fully understood either.
Hence, the authors continued their investigations by using an already refined and proved test setup, which is the base for further characterizations and enhancements.
The presented studies include the characterization of three different friction couples (using the same brake system) for two different test cycles (namely a modified AK Master and a WLTP) in terms of particle number concentration.
Additionally, the major differences of the modified AK Master and the WLTP are investigated and analyzed.
Finally, results of particle mass characterizations introduced.
A brief summary and some conclusions are presented in the final chapter.
