- Application :For black smoke filtration of diesel engines
- Specification
- FAQs
Product Description:
Diesel Particulate Filter (hereinafter called DPF) is designed to remove black smoke (soot, hereinafter called PM) form diesel engine exhaust, making great contribution to clean the exhaust gas from diesel cars while attracting much attention from worldwide car manufacturers.The most effective type is the so called wall-flow filter. Particulate matter is removed from the exhaust by physical filtration using a honeycomb structure similar to an emissions catalyst substrate but with the channels blocked at alternate ends.Diesel particulate filter is suitable for exhaust gas purification of various kinds of diesel vehicles and ships. We can produce different materials of DPF: Cordierite diesel particulate filter and silicon carbide diesel particulate filter.
Product Feature:
· Low thermal expansion
· High filter specific surface area
· Low pressure drop
· Long-term durability performance
· High soot removal: >95%
· Excellent thermal shock resistance.
. High particulate trapping efficiency, suitable for all kinds of regeneration.
