DPF pore channel structure of diesel engine

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. 本实用新型公开了一种柴油机DPF孔道结构，包括柴油机尾气颗粒捕集器外壳、入气管道、出气管道、DPF陶瓷载体、DPF孔道前半段、DPF孔后半段和孔道，所述柴油机尾气颗粒捕集器外壳内安装有DPF陶瓷载体，所述DPF陶瓷载体设置于进气口至排气口的路径上，所述DPF陶瓷载体上沿其
