Product Description

Diesel Particulate Filter is 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 particular filter bases on honeycomb ceramic substrate, whose materials are cordierite or carborundum. It could trap the particulate matter from diesel exhaust emissions, so they are applied on cars, buses, trucks and so on.

A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies of close to 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures; Engine programming to run when the filter is full in a manner that elevates exhaust temperature or produces high amounts of NOx to oxidize the accumulated ash, or through other methods. This is known as "filter regeneration". Cleaning is also required as part of periodic maintenance, and it must be done carefully to avoid damaging the filter. Failure of fuel injectors or turbochargers resulting in contamination of the filter with raw diesel or engine oil can also necessitate cleaning. The regeneration process occurs at road speeds higher than can generally be attained on city streets; Vehicles driven exclusively at low speeds in urban traffic can require periodic trips at higher speeds to clean out the DPF. If the driver ignores the warning light and waits too long to operate the vehicle above 40 miles per hour (64 km/h), the DPF may not regenerate properly, and continued operation past that point may spoil the DPF completely so it must be replaced.

We are professional manufacture high quality SiC/Cordierite Diesel Particulate Filter. Quality control pass ISO/TS16949 and catalyst reach EURO5/EURO4/EURO3/EURO2/ CARB OBDII/ EPA. Our DPF has successfully installed in cars, buses, trucks, and various construction machinery vehicles, 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.

*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 for too thick coating
*Warm-up characters: After starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time
*Low exhaust resistance: Ask exhaust resistance of substrate to engine low, so that it won't affect the performance of engine
*High intensity: Substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed
*Perfect assembly: Substrates are parts of exhaust; Perfect appearance and exact dimension could ensure assembly perfect

Material: Cordierite silicon carbide
Size: According to clients' requirement
