SiC-based Diesel Particulate Filter Description:
SiC Diesel Particulate Filter of emission is captured inside thin gas hole or entrance. As it lasts, the cumulated layer become thick, and pressure loss increase. To ensure the performance of engine, when pressure loss reaches some value, it is a must to recycle the filter. The recycle is making the particulate burning, by raising the gas temperature of filter. The particulate condition is related to the oxygen concentration. Normally, it is burning at 550-650. Its adopted to raise emission temperature by adjusting throttle, and increase gas temperature with burner. The particulate burning temperature can be decreased by catalyzed, making cumulative particulate burning as soon as possible, thus recover the pressure loss and fitters performance, then the filter is recycled.

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 made of cordierite or silicon carbide. It adopt opening and blocking up passages in both ends and the exhaust gas flow through the porous beehive wall to filter particles.
The characteristics of the wall flow diesel particulate filter as follows:
*Broad band filtration (the diameters of the filtered particles are 0.2-150 μ M).
*Low back pressure.
*High filtration efficiency (can be up to 95%).
*High refractory.
*High mechanical properties.
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.
*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
Silicon carbide Diesel Particulate Filter is mainly used in the diesel engine tail gas purifying system to solve the air pollution problem.
Particulate matter traps systems by offering:
Low thermal expansion
High filter specific surface area
Low pressure drop
Long-term durability performance
High soot removal: >95%
