Engine test beds

Motorprüfstande 1

Engine test beds are used to measure the combustion engine independently of other vehicle components. It is pre-assembled on a pallet system in the workshop and finally assembled on the test bed. The dynamometer is an asynchronous motor and can be used in 4 quadrant operation. That means it is possible to tow-start engines, or to measure their internal friction. The test bed is equipped with state-of-the-art measuring technology.

  • Mechanical development of engine prototypes
  • Engine development and calibration of the engine control unit (ECU) in terms of exhaust emissions
  • Continuous testing
  • Hardware-in-the-loop applications for various requirements
