摘要
介绍了颗粒物测试设备电子低压冲击仪(ELPI)的结构和测试原理,研究了国内外学者应用ELPI测试柴油发动机和汽油发动机颗粒物排放测试方法及技术策略。指出ELPI是目前测试机动车颗粒物全粒径范围排放最有效的设备之一,ELPI的广泛应用,定会对机动车的颗粒物排放,特别是粒径小于2.5μm的颗粒物排放的形成机理、分布特性及控制策略等方面起到了积极作用。
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.
