There is a need for direct tailpipe sampling of diesel vehicles in mines in order to determine the effects of an emissions-based maintenance program, evaluate control technologies such as diesel particulate filters and identify the worst diesel particulate matter (DPM) emitters in a fleet of vehicles. Therefore, this study examined the performance of three portable instruments: a personal dust monitor (PDM) manufactured by Thermo Scientific, a prototype elemental carbon monitor (Airtec) manufactured by FLIR and a prototype AE91 instrument from Magee Scientific. These instruments were evaluated on the basis of their ability to provide direct reading tailpipe analysis for DPM. It was determined that the average bias of the tailpipe results from the PDM and the Airtec were 3±12% and 4±20%, respectively, when compared to the standard method of determining tailpipe particulate concentrations from a diluted exhaust. It was also determined that the AE91 instrument correlated with the standard method.
为了确定基于排放的维护计划的效果、评估柴油颗粒过滤器等控制技术以及识别车队中最差的柴油颗粒物（DPM）排放源，需要对矿山中的柴油车辆进行排气管直接采样。因此，本研究考察了三种便携式仪器的性能：赛默飞世尔科技公司生产的个人粉尘监测仪（PDM）、FLIR公司生产的原型元素碳监测仪（Airtec）以及Magee Scientific公司的原型AE91仪器。这些仪器根据其提供DPM排气管直接读数分析的能力进行评估。结果表明，与从稀释废气中测定排气管颗粒物浓度的标准方法相比，PDM和Airtec排气管结果的平均偏差分别为3±12%和4±20%。还确定AE91仪器与标准方法相关。
