Research area

The department Emissions focuses on pollutant emissions and energy consumption from motor vehicles. Activities include measurements on chassis dynamometers and engine test beds as well as testing with on-board measurement systems as well as developing and applying models that simulate fuel consumption and emissions of motor vehicles with conventional and alternative propulsion systems. Our software ranges from development tools for industry to emission inventories for cities and countries for the purpose of environmental monitoring.

Areas of expertise

  • Measurement of emissions and energy consumption of vehicles
  • Detailed simulation of
    • single vehicles
    • engines
    • auxiliaries
    • vehicle fleets
  • Simulation of alternative propulsion systems (HEV, BEV, PHEV, REX)
  • Development of test cycles from real world driving behavior
  • Simulation of emissions for local, regional and global monitoring tasks


  • EC HDV CO2 Regulation 2017/2400
    Significant contributions in the technical parts of the legal texts, development of test procedures, and implementation of the required software for component evaluation and vehicle simulation.
  • Handbook Emission Factors of Road Vehicles (HBEFA)
    Providing the european standard data base for real-world emissions in all relevant traffic situations for two-wheelers, passenger cars and commercial vehicles.
  • RDE compliance checking
    Checking the "Reald Driving Emissions (RDE)" limit compliance of type approved passenger cars also under borderline driving conditions.
