論文概要
In order to evaluate and limit the actual emissions on the road, the European Commission has introduced the topic of RDE by passing the WLTP legislation in the recent years [1-4]. Since September 2017 measurements on the street are mandatory for the approval of new vehicle types. Portable emissions measurement systems therefore arrived at the daily business of development measurements at Mercedes-Benz. The process of these development measurements is briefly outlined below, the challenges are dealt with afterward in more detail.
The process for obtaining valid road emission data is roughly divided into five process steps, Figure 1. Starting with a suitable adaptation of the vehicle and the installation of the Portable Emissions Measurement System (PEMS), the validation measurement on the chassis dynamometer follows. These validation measurements are not only a recommended legal specification, but also a fixed component for a high-quality and reliable measurement....
