Modes of Operation
The dynamometer can be run in stationary and transient operation. Both braking and towing operation is possible. Diesel, petrol, natural gas and hydrogen driven vehicles can be tested.
Stationäry Operation
Constant traction or constant driving speed
Transient Operation
Simulation of driving resistance forces according to actual vehicle speed and acceleration based on settings for vehicle mass and load road parameters.
Exhaust Gas Analysis
- Exhaust gas analysis from undiluted exhaust gas
- Instantaneous emission data (max. 2 Hz)
- FTIR for 30 exhaust gas components (regulated and non-regulated)
- Particle mass & particle number (CPC 23 nm, 10 nm und 4 nm)
- Brake- & tirewear
This testbed is operated in cooperation between Graz University of Technology and FVT mbh.
