The rapid shift toward vehicle electrification demands accurate assessment of emission factors from tyre and road wear particles (TRWP), generated by mechanical and thermal abrasion during driving. This study develops a methodology for measuring airborne particulate emissions (PM2.5, PM10) under realistic conditions, using on-road testing. Particle generation considers various driving scenarios (urban, regional, motorway), tyre loads, and environmental conditions. An advanced CFD-aided collection system design ensures efficient particle capture and minimizes contamination from other particle sources. State-of-the-art instrumentation is used for the physical characterization of particles and a subsequent chemical analysis supports the separation of the TRWP from other collected particles. Results, covering diverse European-market tyres, address data gaps and contribute to emission inventories, future regulatory activities, air quality assessments, and sustainable tyre development.

摘要

The rapid shift toward vehicle electrification demands accurate assessment of emission factors from tyre and road wear particles (TRWP), generated by mechanical and thermal abrasion during driving. This study develops a methodology for measuring airborne particulate emissions (PM2.5, PM10) under realistic conditions, using on-road testing. Particle generation considers various driving scenarios (urban, regional, motorway), tyre loads, and environmental conditions. An advanced CFD-aided collection system design ensures efficient particle capture and minimizes contamination from other particle sources. State-of-the-art instrumentation is used for the physical characterization of particles and a subsequent chemical analysis supports the separation of the TRWP from other collected particles. Results, covering diverse European-market tyres, address data gaps and contribute to emission inventories, future regulatory activities, air quality assessments, and sustainable tyre development.
