Factory Supply DPF Silicon Carbide Cordierite Diesel Particulate Filterfor of Diesel Cars
DPF is a device designed to remove diesel particulate matter or soot from the exhaust gas of diesel engine vehicles.The DPF filters first trap particulates and then use a catalytic technology to continuously burn them at normal diesel operating exhaust temperatures.
Cordierite material, which is raw material molding and synthesized cordierite after burning, cordierite DPF filters are one of the most viable solutions available for use today.
DPF Filters are one kind of wall-flow monolith, the channels are open at one side, but plugged at the other. it will be installed in the diesel car exhaust system, to reduce particulate matters (PM) of exhaust by trapped. The main components of Diesel engine exhaust are particulate matter(PM), carbon monoxide(CO) and hydrocarbons(HC), Diesel Particulate Filters Can reduce them by 90+% from diesel engines
High filtration efficiency
Low coefficient of thermal expansion (CTE)
Low thermal shock resistance
Low back pressure
Outstanding durability
Low pressure drop
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.

Silicon Carbide Diesel Particulate Filter(DPF)
Silicon carbide diesel particulate filters (Sic wall flow filters) have a higher melting point and filtration efficiency (can be up to 95%) than cordierite, they are usually more expensive than cordierite wall flow filters.
