| Abstract: | This paper introduces the structure and testing principles of electrical low pressure impactor （ELPI）, a particulates testing device. It points out some ELPI testing methods and technical strategies concluded by scholars both at home and aboard in the aspect of particulates emission made by diesel engines and gasoline engines. ELPI is one of the most effective devices for testing the diameter range of particulates emission. The widely usage of ELPI will exert a positive influence on the forming principles, distribute features as well as control strategies,especially on the particulate with a diameter less than 2.5μm. |
