Emission measurements

Emission measurements provide input parameters for atmospheric models and are thus of great importance for the description of the composition of the atmosphere. Targeted emission studies, however, can also serve to reduce engine emissions e.g. by changes in the fuel composition or by the use of new catalysts. Some examples from physical chemistry in Wuppertal are listed below:

  • Quantification of trace emissions (nitrous oxide, methane) from power plants and small firing plants
  • Quantification of trace emissions (nitrous oxide, methane, hydrocarbons) from aircraft engines at combustion chamber, engine, and height test stands
  • Quantification of trace emissions (HONO, NOx, HCHO, particles) of motor vehicle engines on engine and vehicle test stands as well as in road tunnels
  • Influence of fuel composition on the emissions of motor vehicle engines
  • Proportion of directly emitted NO2 in nitric oxide emissions from motor vehicle traffic
