Cordierite Diesel Particulate Filter 

1. Product use

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:

• 4.Benefits of Products:
• • High specific surface area: ensure exhaust gas could contact with catalyst enough.
• • Stable water absorption: guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it’s no waste for too thick coating.
• • Warm-up characters: after starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time.
• • Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it won’t affect the performance of engine.
• • High intensity: substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed.
• • Perfect assembly: substrates are parts of exhaust; perfert appearance and exact dimension could ensure assembly perfect.
