Real World Brake Activity of Heavy-Duty Vehicles
It is known that PM2.5 emissions from brake PM on-road are as much as PM2.5 emissions from vehicle exhaust. Zero emission vehicles (ZEVs) are typically much heavier than their internal combustion engine (ICE) counterparts and so ZEVs are expected to emit more brake PM ironically. Some scientists hypothesize that the regenerative brake system of ZEVs can mitigate brake PM emissions but this hypothesis was never examined experimentally. This study aims to investigate the influence of regenerative brake system on the brake PM emissions using vehicles which has both BEV and ICE versions, or HEV and ICE versions.
