A single layer filtration system was developed to investigate the filtration and regeneration performance of diesel particle filter\n(DPF). The particle layer thickness was directly measured online to analyze the different filtration stages. The influence of particle\nproperty on particle layer stage performance was also investigated. The results indicate that the filtration velocity can greatly affect\nthe deep bed filtration stage, and the deposited particle layer can be compressed even in very low filtration velocity and higher\nfiltration velocity trends to form denser particle layer. Optimizing the pore structure can effectively shorten the deep bed filtration\nstage and reduce the pressure drop eventually. An empirical function was proposed to relate the pore structure and the initial\nincrement rate of pressure drop, which presented that reducing the pore size distribution range (3
