SiC Honeycomb ceramic Substrate

Description

Diesel Particulate Filter (DPF-diesel particulate filter) is a kind of wall flow honeycomb ceramic made of cordierite or silicon carbide. The main component of the exhaust gas emitted by the diesel engine is the carbon particulate, which is installed in the exhaust system of the diesel vehicle. Devices that reduce particulate matter (PM) in exhaust gas by filtering can filter carbon particles more than 90% efficiently, and soluble organic components SOF(mainly high boiling point HC) can also be partially captured. The working principle of the particle trap: by alternately blocking the hole ends of the honeycomb porous ceramic, the wall holes of the ceramic are used to filter out PM.
