메탈 폼 입자 필터의 GDI 엔진 입자상 물질 정화 특성에 대한 연구

Study on the Particulate Matter Filtration Characteristics of the Metal Foam Particulate Filter

After-treatment system for gasoline direct injection engines should be considered due to the regulation standard for particle number emitted from spark ignition engine vehicles. A metal foam particulate filter, which is thought to be more proper for gasoline engines for its unique filtration and heat resistance characteristics, has been evaluated via engine dynamometer tests.
