Vehicles are tested in controlled and relatively narrow laboratory conditions to determine their official emission values and reference fuel consumption. However, on the road, ambient and driving conditions can vary over a wide range, sometimes causing emissions to be higher than those measured in the laboratory. For this reason, the European Commission has developed a complementary Real-Driving Emissions (RDE) test procedure using the Portable Emissions Measurement Systems (PEMS) to verify gaseous pollutant and particle number emissions during a wide range of normal operating conditions on the road. This paper presents the newly-adopted RDE test procedure, differentiating six steps: 1) vehicle selection, 2) vehicle preparation, 3) trip design, 4) trip execution, 5) trip verification, and 6) calculation of emissions. Of these steps, vehicle preparation and trip execution are described in greater detail. Examples of trip verification and the calculations of emissions are given.
车辆在受控且相对狭窄的实验室条件下进行测试，以确定其官方排放值和参考燃油消耗。然而，在道路上，环境和驾驶条件可能会有很大变化，有时会导致排放量高于实验室测量值。因此，欧盟委员会制定了一种补充性的实际行驶排放（RDE）测试程序，使用便携式排放测量系统（PEMS）来验证车辆在道路上各种正常运行条件下的气态污染物和颗粒物数量排放。本文介绍了新采用的RDE测试程序，分为六个步骤：1）车辆选择，2）车辆准备，3）行程设计，4）行程执行，5）行程验证，6）排放计算。在这些步骤中，对车辆准备和行程执行进行了更详细的描述。给出了行程验证和排放计算的示例。
