Abstract: Ceramic honeycomb bodies and methods for canning the bodies are disclosed herein. The honeycomb bodies comprise a porous ceramic honeycomb structure. The honeycomb structure comprises a network of cells defined by walls that extend in an axial direction about a longitudinal axis from an inlet end to an outlet end of the honeycomb structure. The honeycomb structure also comprises a portion of cells with protrusions. The portion of cells with protrusions supports a greater concentration of catalyst, as compared to a portion of cells without protrusions. The portion of cells with protrusions is disposed off-center with respect to the longitudinal axis of the honeycomb structure such that the portion of cells with protrusions (and greater concentration of catalyst) corresponds to areas of high exhaust flow through the structure.

Abstract: A particulate trap filter body has asymmetrical channels. The cross-sectional shape of the asymmetrical channel structure includes a combination of hexagonal, square and triangular shapes. The hexagonal channel and the triangular channel act as inlet channel, and the square channel acts as outlet channel. Compared with the traditional symmetrical filter body structure, the inlet channel volume and filter body wall area can be effectively increased by more than 30%, which means that with capturing the same amount of particles, the particle cake layer formed on the wall surface is thinner. The limiting carbon load of the new channel structure is increased by more than 30%, having a very positive effect on reducing the regeneration frequency and prolonging the service life of the trap.
