摘要

基于柴油机颗粒捕集器外加热源再生性能测试台架，对比研究了钛酸铝和碳化硅材料对柴油机颗粒捕集器（DPF）和催化型柴油机颗粒捕集器（CDPF）再生性能的影响规律。试验结果表明：随着来流温度的增加，不同材料载体的最高温度和最大温度梯度先缓慢增加后迅速增加，而再生效率逐渐呈线性增大，再生温度的陡增不能直接使再生效率陡增；在炭黑剧烈再生时，钛酸铝材料的最高温度和最大温度梯度远高于碳化硅材料载体；压降随来流温度、炭黑担载量的增加而增大，压降大小与材料孔隙率、孔径及载体本身的结构有关。

Abstract

The influence of the aluminum titanate(AT) and silicon carbide(SiC) substrate materials on regeneration performance of DPF and CDPF was investigated on a regeneration test bench with additional heating sources. Results indicate that the maximum temperature and maximum temperature gradient for different substrate materials of DPF and CDPF increase slowly first and then increase rapidly with the rise of regeneration temperature. The rapid increase of regeneration temperature can't directly lead to an improvement on regeneration efficiency. The maximum temperature and maximum temperature gradient of AT are much higher than that of SiC

when the rapid regeneration of soot. The pressure drop increases with the rise of regeneration temperature and soot loading

which is related to the porosity

pore diameter

and structure of the substrate.
