Laboratory for vehicle emissions and powertrain

Our laboratory is specialised in powertrain and emission measurements. We provide these services and carry out certifications. Our activities also include research and development (R&D).

The measurements are performed in a controlled environment (on engine test benches or chassis dynamometers) and under real in-use conditions (real driving emissions, in-use emission testing), using specific instrumentation.

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.


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
