IC-Engines and Exhaust Emissions

We are specialized in measurements and R&D of cars and combustion engines with roller- and engine dynamometers. Two roller- and five engine-dynamometers are available.

Our Laboratory

Among other things, our laboratory carries out legal measurements and several projects in the field of "Vehicles and Environment" for the industry and public authorities. In addition, we carry out tests for the certification of diesel exhaust aftertreatment systems, which are intended for on-road and off-road use. Our laboratory equipment enables the measurement of limited and non-limited exhaust components.

Services

The range of services offered by the engine laboratories and the exhaust gas testing centre includes:

  • R&D work on engines or vehicles (according to the technical competencies, see below)
  • Quality inspections and R&D work on exhaust aftertreatment systems for gasoline and diesel engines
  • Legal exhaust emission tests for 2-, 3- and 4- wheel vehicles up to 3.5t total weight (incl. RDE)
  • R&D work on electric and hybrid vehicles
