随着实验室和真实的世界汽车排放的欧洲法规限制的严格性增加，改善空气质量的主要交通相关方面之一是大规模在用车辆测试。固体颗粒数（SPN）排放量已大大减少与柴油和汽油颗粒过滤器的使用，但可能会被损坏，甚至被篡改。正在讨论机载监测和遥感以及目前定期技术检查以发现微粒过滤器失灵或被篡改的可行性。一个有前途的方法来检测高发射器是SPN测试在低怠速期间PTI。一些欧洲国家计划为柴油车辆引入这种方法，欧洲委员会（EC）将提供一些指导方针。在不同仪器制造商的参与下，欧盟委员会联合研究中心（JRC）组织了一项实验活动。测量了没有或有故障颗粒过滤器的车辆的怠速SPN浓度。目前的截止尺寸为23纳米的颗粒以及挥发性颗粒在空转期间的存在。此外，研究了过滤器再生后测试的性能良好的车辆的极端情况。在大多数情况下，所使用的不同传感器具有良好的一致性，由于传感器在截止尺寸以下的效率差异，高的亚23 nm颗粒的存在是最具挑战性的情况。
Following the increase in stringency of the European regulation limits for laboratory and real world automotive emissions, one of the main transport related aspects to improve the air quality is the mass scale in-use vehicle testing. Solid particle number (SPN) emissions have been drastically reduced with the use of diesel and gasoline particulate filters which, however, may get damaged or even been tampered. The feasibility of on-board monitoring and remote sensing as well as of the current periodical technical inspection (PTI) for detecting malfunctioning or tampered particulate filters is under discussion. A promising methodology for detecting high emitters is SPN testing at low idling during PTI. Several European countries plan to introduce this method for diesel vehicles and the European Commission (EC) will provide some guidelines. For this scope an experimental campaign was organized by the Joint Research Centre (JRC) of the EC with the participation of different instrument manufacturers. Idle SPN concentrations of vehicles without or with a malfunctioning particulate filter were measured. The presence of particles under the current cut-off size of 23 nm as well as of volatile particles during idling are presented. Moreover, the extreme case of a well performing vehicle tested after a filter regeneration is studied. In most of the cases the different sensors used were in good agreement, the high sub-23 nm particles existence being the most challenging case due to the differences in the sensors’ efficiency below the cut-off size.
