摘要
用于减少柴油机颗粒物排放最有效的后处理装置就是壁流式颗粒物捕集器。对颗粒物捕集器CDPF载体部分温度场的分布进行试验研究,分析了最大温度梯度和温度峰值与流场之间的关系,同时验证了利用后喷和外部喷射进行主动再生期间温度场分布的不同。
The paper mainly studied and tested the temperature field during regeneration in DPF, and analyzed the relationship between flow field and maximum temperature gradient and peak temperature. At the same time, it verified the difference of temperature field between post injection and external injection during regeneration.
