Dinex - Silicon Carbide Diesel Particulate Filter
The primary function of a DPF is to trap and reduce particulate matter mass (PM) in the diesel exhaust by > 95 % and the particulate number (PN) by > 99 % at the cost of minimal possible back pressure and should be able to sustain high thermal loads.
Dinex Silicon Carbide DPF (SiC-DPF) is a robust substrate technology with moderate back pressure under high soot and ash loads. It is available at a porosity level of 52% for catalysed DPF applications and at a high porosity level up to 65% to accommodate high wash coat loadings, typical of SCR-DPF applications. The coated filters feature a thin but powerful coating designed to work under passive as well as active regeneration strategies.
The high porous Silicon Carbide is based on a reaction forming process of silicon and carbon in-situ to SiC. The final porous structure is built up by hexagonal plate like crystals, which build a three-dimensional network with a high pore volume.
