摘要
非尾气颗粒物排放已超过车辆尾气颗粒物排放,但限制非尾气排放的法规仍不完善.本文综述了机动车制动颗粒物排放的试验方法和粒径分布特征.制动磨损颗粒物的测试方法主要包括销盘法、惯性制动台架法、底盘测功机法和实际道路法.研究发现,受制动摩擦片材质、制动运行特征、制动力、温度、路况和测试工况等多种因素影响,制动颗粒物的粒径分布没有典型的统一特征,具有单峰、双峰和多峰等多种粒径分布形态.
Abstract
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.
