Product Description

A diesel particulate filter removes particulate matter from diesel exhaust by physical filtration. The common type is a ceramic (cordierite or silicon carbide) honeycomb substrate. The structure like an emissions catalyst substrate with the channels blocked at alternate ends. The exhaust gasses must therefore flow through the walls between the channels and the particulate matter is deposited on the walls. Other filter types are available, using sintered metal plates, foamed metal structures, fibre mats and other materials as the filtration medium.



Diesel Particulate Filter is designed to remove black smoke (soot, hereinafter called PM). We offer all kinds of diesel particulate filters with top quality and competitive cost. Diesel particulate filter effectively remove diesel particulate matter and soot from diesel engine exhaust emission. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. 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. Silicon carbide filter cores also look like catalytic converter cores that have had alternate channels plugged - again the plugs force the exhaust gas flow through the wall and the particulate collects on the inlet face.

Material: Cordierite, Silicon carbide

Size: According to clients' requirement

Advantages:
*Excellent capturing performance
*Small exhaust back pressure
*Nice corrosion resistance to oil, ash, and engine scouring
*Excellent heat resistance and thermal shock resistance
*Lower thermal expansion

Properties of Diesel Particulate Filter used in Cars/Trucks/Diesel Engine etc as follows:
*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
