In 2022, just 15 % of overall particle related emissions originated from the tailpipe were regulated. 85 % of the emissions were non-regulated and originated from sources such as brake wear, tire wear and road abrasion. To respond to this, a testing procedure for brake wear was validated and has been implemented as a new global testing regulation at the start of 2023.
Based on this, GTR-compliant particle mass and particle number (PM10, PM2.5 and CPC-based SPN & TPN measurement) must be measured over a specified brake cycle on a brake dyno.
The AVL Brake Emission Solution is an all-in-one testing solution to measure the particle mass and number concentration of braking systems on a high-end brake dynamometer under variable, highly dynamic testing conditions.
- Highly dynamic AVL Dynamometers
- Optimized sampling system for minimal particle loss
- APC technology in a device that measures particle number concentration, solid particle number (SPN), and total particle number (TPN)
- Cost-efficient gravimetric filter modules for PM 2.5 and PM 10
- Highest automation degree with the xChange option - up to 16 filter pucks can be stored and swapped automatically within the device between the tests
- Highest weighing accuracy using the optional AVL Filter Weighing Chamber

WEBINAR - Brake wear is one of the most significant non-exhaust traffic-related sources of particulate matter and, as a result, will be included in future emission regulations. Due to the broad size range of brake wear particles new instruments are required.
WEBINAR - Forthcoming automotive regulations will include requirements for brake wear emissions on top of the existing exhaust limits, leading to additional research and development, testing and homologation efforts.
WEBINAR - Upcoming non-exhaust emissions regulations, starting with brakes, will impact the complete vehicle development process due to the interaction between brake components, materials, performance, comfort, and vehicle systems.
WEBINAR - The upcoming European vehicle emission standards Euro 7 publication by the European Commission will outline testing and certification updates which will need to be addressed when developing future propulsion solutions.
As automotive emissions continue to stay in the focus of environmental regulations, OBM (On-Board Monitoring) emerges as a substantial instrument for ensuring emission compliance with EU7 standards.
The 13th International AVL Emissions and Energy Forum will take place on April 23rd and 24th in Ludwigsburg near Stuttgart, Germany. The Forum will focus on the climate-neutral energy basis for the mobility of the future.
