With increasing appearance of diesel engine automobile, the particulate from emission, mainly carbon
1. Diesel Particulate Filter substrate: Our DPF subsrtate was an economic porous wall flow type ceramic filter is also available for diesel particulate mater removal called diesel particulate filter.
Such a ceramic filter is made from modified cordierite ( 2MgO-Al2O3-5SiO2), our DPF enable highly efficient particulate matter trap systems by offering:
*Low thermal expansion
*High filter specific surface area
*Low pressure drop
*Long-term durability performance
*High soot removal: >95.4%
*This product was only the carrier for the Catalyzed diesel particulate filter (CDPF) as below.
2. Catalyzed diesel particulate filter (CDPF)
Catalyzed diesel particulate filters are the solution for diesel particulate matter control. >95% PM filtration efficiency and low regeneration temperature are achieved through the combination of wall flow type ceramic honeycomb with patented catalyst formulation. In additional of PM reduction, catalyzed diesel particulate filter is also reducing carbon monoxide and hydrocarbon from engine exhaust stream.
Current product offer covers from 2.5 liters (5.66x6") to 25 liters (11.25x15") as a single CDPF which would be perfect solution for diesel engine displacement from 2 to 20 liters.
Key characteristics of catalysts include:
*Low pressure drop
*Excellent performance
*Self-regenerationunder special conditions
*Can be applied to on-road and off-road diesel engines
*Can be provided in a standard or custom configurations
