The institute has extensive technical equipment at its disposal. There are dynamic engine test benches, a large number of specialised autonomous measuring systems and powerful simulation and calculation tools.
Engine Test Benches
6 engine test benches with electric load machines (4-quadrant drive) from 400 to 630 Nm torque with 200 kW power each.
- Oil, water, air and EGR conditioning. Flexible maximum pressure injection
- Programmable test bench control system
- Flexible indexing possibilities
- Fuel consumption and air mass measurement
- Exhaust gas analysis systems
- Variable pallet system
Further loading devices (2-quadrant, water vortex brake) are available.
