다공성 세라믹 펠렛을 포집재로 사용하느 매연여과장치의 배압 및 재생 특성에 관한 연구

A Study on the Characteristics of Pressure Drop and Regeneration of a Porous Seramic Pellet Filter for Diesel Particulate Trap

  • 발행 : 2003.05.30

초록

Diesel particulate trap is a core technology for the reduction of PM from diesel vehicles This study presents the features and the characteristics of DPF system when using pellet type filters. In comparison with wall-flow filter, the pellet filter has the advantages of cracking free during regeneration and shape flexibility. Experiments are conducted in a test bench simulated as diesel engine exhaust condition. Pressure drop and particle loading rate was compared by using two pellet filters having the porosity of 70% and 0%. Also its regeneration was tested.
