Based on self designed burner-type system diesel particulate filter (DPF), the temperature of both gas in burner mixed with combusted combustion gas by several fuel-air matching forms and diesel exhaust gas was experimentally studied. The pyrogenation regeneration model for a channel of DPF was used to obtain the regeneration computational result, which is verified to match with experimental results well. Further, according to simulation results, the problem of fuel-air matching forms on idle condition was analyzed in regeneration performance requirements, such as wall maximum temperature, temperature gradient, regeneration time and so on, to achieve the reasonable matching for burner-type DPF.
