Diesel particulate filter

cordierite DPF, which consists of parallel channels, separated by thin walls made of porous cordierite. The channels are open at one end, but plugged at the other. During operation, the exhaust gases are forced to flow through the thin walls and leave particulates trapped in the filter walls.

Cordierite DPF is mailnly used in the diesel engine automobile to solve the air pollution problem. The effect is better than the ceramic substrate.

DPFs enable highly efficient particulate matter trap systems by offering:

• Low thermal expansion

• High filter specific surface area

• Low pressure drop

• Long-term durability performance

• High soot removal: >95%
