Research on Internal Transfer Phenomena of the Diesel Particulate Filter Performance (Third Report)

- Experimental Study of the Effect of PM Loading Condition on Filter Wall Layer -

Abstract

Experimental studies were conducted on the Diesel Particulate Filter (DPF) under different PM loading conditions with different DPF configurations. Firstly, pressure drop through the DPF with various mean pore diameter of DPF wall and wall thickness configurations were measured. Secondly, pressure drop through the DPF under various mean particle diameter and gas flow rate conditions were measured. Thirdly, hypothesis of mechanism, which took the effects of PM loading regime in the wall and on the PM cake layer on pressure drop into account, was proposed..
