摘要：
Non-exhaust particles produced from brake wear and tire wear have become the main source of vehicle particle emission，surpassing the exhaust particle emission，as the limitation of exhaust gas becoming more stringent. A review of existing researches on brake particle emission is conducted. Some researches have shown that particle number emission under real driving condition could reach 1012 #/km level ，with particle mass emission up to 21 mg/km，which both exceed the limita-tion of exhaust gas in China VI regulation，in addition，a significant amount of which are ultrafine particles with carcinogenic PAHs. In the future，more regulations should be formulat⁃ ed to regulate measurement and control methods of brake particles. © 2024 SAE-China. All rights reserved.
