Cordierite DPF Honeycomb Ceramic

Short Description:

Cordierite Diesel Particulate Filter(DPF)
The most common filter is made of cordierite. Cordierite filters provide excellent filtration efficiency, are relatively
inexpensive (comparison with Sic wall flow filter). The major drawback is that cordierite has a relatively low melting point.

Working principle

By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter is deposited on the walls,so reducing the amount of air pollution.
