Resumen: Given the amount of diesel vehicles worldwide and their overall environmental impact, particulate emission control is an increasingly important issue. Particles control systems based on improvements of the combustion process or on the design of the engines are not sufficient to comply with current regulations. Therefore, the use of aftertreatment systems has become necessary. The most popular aftertreatment device for the abatement of particles, the wall-flow Diesel Particulate Filter (wall-flow DPF), still has a considerable scope for improvement. The high backpressure they introduce in the exhaust pipe, and the technical issues associated with the on-board regeneration process are some of the most concerning aspects. The aim of this work is to develop a new substrate for wall-flow Diesel articulate Filters based on a novel porous ceramic material: biomorphic silicon carbide (bioSiC). BioSiC is a particular type of silicon carbide obtained from the pyrolysis of wood and its subsequ...
