In order to eliminate TPM(Total Particulate Matter) from a diesel engine, we designed and developed a particulate trap system using a burner, which was named as AEFR(Active Exhaust Feeding Regeneration) system. We have considered the temperature distributions and gradients in the filter being regenerated according to regeneration control schemes Ⅰ, Ⅱ and Ⅲ. Schemes Ⅲ has shown the most desirable peak temperature and temperature gradients in AFER system. Finally, it was concluded that much lower peak temperature and temperature gradients in the filter could be obtained than that of other advanced research results by our AEFR system.
