DPF diesel particulate filter used as catalytic converters of gasoline engines, the honeycomb ceramic catalyst substrates are coated by catalyst. At the same time, we improve the specific surface areas and cut down the heat capacity to increase the catalytic function. When the noxious emissions pass through, HC, CO and NOX will be converted into harmless components.

Diesel particulate filter is also called Diesel Particulate Filter (DPF). The main composition of
Tail gas discharge from diesel is carbon particulates. Cordierite Diesel particulate filter adopt cordierite as its material. Its main compositions are SiO2, AL2O3 and MgO. Working principle of particulate filter: Plugging up two ends of porous beehive ceramic in turns to filtrate PM by ceramic wall.

Features:
*High specific surface area: Ensure exhaust gas could contact weigh catalyst enough
*Stable water absorption: Guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste to the thick coating
*We can provide honeycomb ceramic substrate coated and non-coated with noble metal
*We can produce the honeycomb ceramic series with different shapes and sizes according to customers' requirements
