Product Description

Diesel particulate filter is also called Diesel Particulate Filter (DPF). The main composition of tail gas discharge from diesel is carbon particulates. Diesel particulate filter is a setting to reduce emission granule by filtrating which is set in exhaust system in diesel. Its efficiency for carbon particulates filtration is more than 90%. Part of dissoluble organic composition (SOF) (especially high boiling point) may be trapped.
The filtration material researched and used in China at present is of three types: Ceramic, metallic and composite based. The common types are ceramic based (cordierite or silicon carbide) and metallic based (stainless steel wire mesh) diesel particulate filter.
Working principle of particulate filter: Plugging up two ends of porous beehive ceramic in turns to filtrate PM by ceramic wall.
Regeneration of filter: Burn the particulates by rising the gas temperature in filter to filtrate PM which piled in the filter so as to guarantee the function of filter. The character of particulates in exhaust gas of diesel relates to concentration of oxygen. It will burn in temperature of 550-650° C.

Cordierite Diesel particulate filter (DPF)
Cordierite Diesel particulate filter adopt cordierite as its material. Its main compositions are SiO2, AL2O3 and MgO.
Diesel Particulate Filter adopts structure of honeycomb. It sets up independent opening and blocking up passages in both ends and the waste gas enters from one open end, then goes through the porous beehive wall, and finally discharges from adjoining passage. The carbon particulates are left over on passage wall because they are too big to pass through wall hole and won't be discharged to air.

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 BHLJ 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
