摘　　要：柴油机排气微粒捕集器的关键技术之一就是捕集器的再生.应用热重/差热同步分析仪,在空气、氧气两种气氛下对柴油机排气微粒进行燃烧特性实验,并就微粒的失重曲线和燃烧特性曲线、燃烧特征参数以及燃烧反应动力学等方面进行了分析.结果可以为柴油机排气微粒捕集器再生技术的实施提供指导和依据.With a thermogravimetry, the combustion characteristics of diesel exhaust particulates with air and oxygen were studied experimentally. The results about TG curves and DTG curves, fire point temperature, combustion characteristic parameter and combustion kinetic characteristic parameters were analyzed. The results can provide a reference to carrying out the regeneration technology with regard to diesel exhaust particulate filters.
