摘　　要：随着汽车排气颗粒物排放标准的日益严格化,制动、轮胎磨损等产生的非排气颗粒物已经超过排气颗粒物成为汽车颗粒排放的主要来源。本文综述了制动颗粒物的研究现状,已有研究表明轻型车实际驾驶条件下制动产生的颗粒物PN排放能够达到10~(12)#/km级别,PM排放最高可达21 mg/km,均超过国六尾气排放限值,并且有相当一部分集中在极细颗粒物水平(<100 nm),且颗粒物中含有PAHs等致癌物质。未来应制定相应的标准,规范制动颗粒物测量和控制方法。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.
