디젤기관에서 세라믹 필터트랩에 의한 입자상물질 저감에 관한 연구 (I)

The purpose of this study is presented a theoretical analysis and test for throttling type as regeneration method in diesel engine. In this study, it is introduced the general contents about exhaust emission reduction method, regeneration methods and regeneration characteristics. To verify the reliabilty of regeneration simulation program, the distributions of wall temperature and back pressure during regeneration period at the steady state condition(engine speed of 1000 rpm and torque of 421Nㆍm)are measured in engine dynamometer. From the comparison between the calculated and measured results, it is found that this regeneration program can be actual application and use to know various regeneration phenomenon.
