摘　　要：为验证乘用车内相关空气净化装置对车内颗粒物的过滤性能,通过设计整车级车内颗粒物过滤测试方法,并进行试验方法验证,实现了在整车状态下检测验证试验样车对车内PM_(2.5)的过滤能力。结果表明:本整车级车内颗粒物过滤测试方法可靠有效,车内颗粒物过滤能力6次重复检测净化时间t极差为14s、相对标准偏差为2.2%。In order to verify the filtration performance of relevant air purification devices in passenger cars for particulate matter in the vehicle,the test method for particulate matter filtration in the vehicle at the vehicle level was designed and verified,and the test method was realized to detect and verify the filtration capability of the test sample vehicle for PM_(2.5) in the vehicle under the vehicle state.The results show that this vehicle-level particulate filter test method is reliable and effective,and the range of purification time𝑡𝑡for six repeated tests of particulate filter capacity is 14s,and the relative standard deviation is 2.2%.
