摘要
基于《轻型汽车污染物排放限值及其测量方法(第六阶段)》排放标准正式推出的具体国情,阐述了汽油机颗粒物捕集器中积碳和灰分的生成机理和相应的质量估计模型,介绍了汽油机颗粒物捕集器的再生管理和温度保护机制,明确了捕集效率的计算。
Under the specific background of the publication of the emission limitation and measurement method for the light-duty vehicle(sixth stage),the mechanism and mass estimation model of soot and ash in the GPF(gasoline particulate filter)are elaborated.The regeneration method and temperature management of GPF are explained.The filtration efficiency calculation is introduced.
