Bridgestone develops new technology for TRWP collection

Tokyo – Bridgestone Corp. has developed a new tire and road wear particles (TRWP) collection system to further its understanding of the environmental impact of particles emissions.

Presented during the Tire Technology Conference in Hanover earlier this month, the method involves isolating tires by a device that covers the entire tire to eliminate the influence of exhaust emissions and break dust.

TRWP are then collected through a suction hose for further analysis, explained Bridgestone in a 5 March presentation.

Bridgestone carried out a number of tests at its B-Mobility proving ground in Tokyo using autonomous driving to eliminate human error to collect the particles.

Furthermore, the Japanese group said it “visualised” the dispersion of particles using a high-speed camera with laser light scattering, enabling it to further study the  emissions.

The efficient collection of TRWP, Bridgestone said, will help the group accelerate R&D and enhance its understanding of the physical and chemical characteristics of particles.
