Diesel Particulate Filters
Diesel Particulate Filters relates high-pure Sic Honeycomb-shaped ceramic catacher. quality certificate pass ISO/TS16949. Quality control pass ISO/TS16949 and catalyst reach EURO5/EURO4/EURO3/EURO2/ CARB OBDII/ EPA. Diesel Particulate Filters has succesefully installed in cars, buses, trucks, and various construction machinery vehiles, DPF's life WITHIN the 300,000km, collection efficiency range 97percent. Heat regeneration is made through the displacement management, and the ashes left from the regeneration shall be cleaned regularly.
After coated with catalysts, this product is applied in catalytic converter of diesel vehicle to catalyze, convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV and Euro V. Technical performance of the product in the leading position in domestic, close to or reach the advanced level of similar foreign product.
Benefits of Products:
*Low thermal expansion coefficient
*High porosity of hole on the wall , good liquidity and uniform distribution.
*High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong.
*The pressure drop is small.
*Cold start performance is good, low light-off temperature, high conversion efficiency.
