Non-symmetrical cellular ceramics carrier (DPF) for diesel engine carbon smoke particulate filter

product center

Product Application
This product is made of cordierite material and is a wall flow honeycomb ceramic carrier with a special structure composed of two types of pores of different sizes. It is used in diesel engine exhaust purification devices, using the pores on the wall of the wall flow filter body to intercept and capture carbon smoke particles in diesel vehicle exhaust, purify diesel vehicle exhaust, and meet the national VI and non road T4 emission standards.
