The SiC composite diesel particulate filter (DPF) from Ceramiques Techniques et Industrielles (CTI) and the IFP is made using a cost-effective manufacturing process that enables the production of many different sizes and shapes. Offering filtration efficiency to target Euro 5 and 6 emissions limits, the SiC provides high thermal conductivity leading to an efficient and complete regeneration. The DPF also offers chemical resistance to acids and ash, high durability even after harsh aging treatments, and good adhesion to wash-coat formulation proposed by catalyst manufacturers. Used for many years on buses, trucks, and off-highway vehicles, the SiC composite DPF is three to four times under the limit of the Euro 5 emissions standards of 5 mg/km on MVEG cycles, says CTI.
