Characterization of Particle Number Setups for Measuring Brake Particle Emissions and Comparison with Exhaust Setups

Atmosphere, 2023
The stringency of vehicle exhaust emissions regulations resulted in a significant decrease in exhaust particulate matter (PM) emissions over the years. Non-exhaust particles (i.e., from brakes and tyres) account for almost half or more of road transport ...
