ceramic honeycomb
Ceramic Honeycomb 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.
