Authors Abstract
Content
SiC has very high thermal conductivity and mechanical strength. The cracking problem during regeneration could be successfully handled by using split-type DPFs that consist of multiple filter segments. For enhancing further durability of SiC-DPF, increasing the regeneration limit was successful by means of increasing a volume of the neck area located between SiC particles. The improvement was probably due to the lowering of Young's modulus and increasing of the thermal shock fracture resistance parameter R', which were results of increasing the neck volume and controlling the sintering method. Crack propagation mode changed from the conventional mode, and the cracks propagating throughout the whole tended to be restrained.
