Real Driving NOx Emissions of European trucks — •Tim Adler, Denis Pöhler, Christof Krufzik, Martin Horbanski, Johannes Lampel, and Ulrich Platt — Institute of Environmental Physics, Heidelberg, Germany

NO_x is one of the most problematic pollutants and thus emissions of e.g. trucks are strongly regulated. However, real emissions are typically not investigated. During a study the NO_x emission of more than 200 trucks under real driving conditions on the German highway was investigated. Therefore, a NO_x-ICAD-instrument (Iterative Cavity Enhanced DOAS) together with a CO₂ sensor were used to determine the pollutants in the emissions plume. We developed an algorithm to automatically evaluate the time series and compute the emission for each vehicle based on the plume chasing principle.

For most trucks of our data set the brand, the model name, the country of registration and its EURO class could be determined and used in a statistical analysis. Our data showed that that the emission of individual trucks are much higher than the allowed EURO Norm. The results and statistical analysis including different brands, EURO classes, country of registration etc. will be presented.
