Testing Technology For Brake Wear Particulate Matter:A Review
The emissions of non exhaust particulate matter have exceeded the emissions of vehicle exhaust particulate matter,but the regulations limiting non exhaust emissions are still incomplete.This article summari-zes the test methods and particle size distribution characteristics of brake wear particulate matter emissions.The testing methods for brake wear particles mainly include pin disc method,inertia brake bench method,chassis dy-namometer method,and actual road method.Research has found that the particle size distribution of brake parti-cles does not have typical unified characteristics due to various factors such as brake lining material,brake oper-ating characteristics,braking force,temperature,road conditions,and testing conditions,and has multiple par-ticle size distribution forms such as single peak,double peak,and multi peak.
