Reduction of brake wear emissions from urban heavy-duty transport

Research Project, 2025 – 2029

Particulate emissions from road transport cause thousands of premature deaths every year, and brake emissions account for a significant part. The upcoming Euro 7 legislation introduces limits on emissions from brake wear, where limit values and methods are still under development. This interdisciplinary project provides process understanding of the mechanisms of particle generation and how they can be minimized and includes:
• Characterization of Brake Wear Emissions: Understanding of wear emissions in mass, number, size distribution, and chemical composition.
• Temperature Modeling: Analysis of temperatures at the interface between brake pads and discs and heat transfer dynamics.
• Real-world conditions vs. test conditions: Evaluation of differences in braking energy, temperatures, and wear characteristics.

The project aims to minimize the environmental and health impact of brake wear, especially in urban environments, and contribute to a sustainable transport system.
