| description | The utility model discloses a diesel engine DPF pore channel structure which comprises a diesel engine tail gas particle trap shell, a gas inlet pipeline, a gas outlet pipeline, a DPF ceramic carrier, a DPF pore channel front half section, a DPF pore channel rear half section and a pore channel. A plurality of parallel hole channels are formed in the DPF ceramic carrier in the axial direction of the DPF ceramic carrier, the hole channels are divided by air-permeable hole walls, one end of the DPF ceramic carrier is open, the other end of the DPF ceramic carrier is closed, and the hole channels are wave-shaped channels. Soot on the filtering wall surface of the DPF can be conveniently removed during regeneration operation, tail gas is firstly subjected to coarse filtration and then is subjected to fine filtration, and the filtering effect of DPF pore channels can be improved.
