Presentation Title: Influence of the Run-In Methodology on the Particle Number Emission of Brakes (EB2021-EBS-003)
Session: Brake Emissions Macroscopic Part 1, Wednesday 19th May 2021, 09:00 - 10:40 (Central European Summer Time - CEST)
What do you find most interesting about the topic of your presentation?
The strong influence of the run-in procedure on the particle number emission, in particular on the stability, reproducibility and repeatability of the results. In addition, stable results can be better achieved with shorter run-in procedures than with five repetitions of the WLTP-Brake (Worldwide Harmonised Light Vehicles Test Procedure-Brake).
When discussing this topic with industry peers, what question are you most frequently asked? How do you answer it?
Which particles cause the instability in terms of size and state. During the campaign, the measuring instruments to clarify this question were not yet available, but studies already published later show that some of the particles are solid nanoparticles.
Who do you think will be most interested in your presentation, and who would you most like to ask questions about it?
All those who want to evaluate brakes in terms of their emissions, therefor the brake industry, public authorities and environmental organizations. I want to ask experts who also looked into this topic
What specific topics or technology are you hoping to see in other presentations or in the exhibition?
EV braking, optimized brake components and regulatory specifications, all regarding emissions.

About Katharina Kolbeck.
Katharina Kolbeck is a doctoral student at BMW with focus on brake particle emission. She studied chemical engineering at Technical University Munich, including a master thesis at BMW within the field of exhaust measurement technology. She started her PhD at the Technical University Ilmenau under the supervision of Prof. Klaus Augsburg in 2017. The aim of her thesis is to gain a better understanding about the formation of brake particles in friction brakes by in-situ observations of the frictional contact. She is also a part of the brake particle emission project team at BMW.
