Mobile engine test bench for finished vehicles: versatility and precision

A mobile engine test bench has been developed to test automotive engines up to 150 kW, with the ability to quickly change 15 different engine types. The design includes a square tubular frame resting on either locking spindles or rubber rollers, a clever coupling solution, support device and comprehensive measurement technology for power and consumption measurements and efficiency analysis. This solution meets the demanding test requirements for vehicle engines.


Our progressive Engine test bench was specially developed to test vehicle engines with an output of up to 150 kW. With the Development of the engine test bench the following important aspects were taken into account:

  1. Mobility of the engine test bench: The test bench must be mobile to ensure flexibility of use.
  2. Universal motor connection: The motor test stand can accommodate up to 15 different motor types thanks to an interchangeable mounting bracket.
  3. User-friendly clamping device: The clamping device of the engine test stand is quick and easy to operate.
  4. High load capacity: The engine test bench can withstand loads of up to 7,500 rpm.
  5. Simple coupling: The motor and water whirl brake are connected by a commercially available coupling that enables quick disconnection.
  6. Independent engine start: The engine can be started without external starting aid.
  7. Flexible engine support: The engine test stand has a quickly adjustable support for the engine.


The engine test bench can perform the following tests:

  • Power measurement (torque, speed)
  • Oil temperature measurement (inlet and outlet temperature)
  • Water temperature measurement (inlet and outlet temperature)
  • Consumption measurement
  • Control characteristic
  • Driving simulation



The entire testing device of this engine test rig is mounted on a stable square tubular frame, which rests either on locking spindles or on rubber rollers for the drive function. The frame of the engine test stand contains the measuring shaft, bearings and a coupling. A bayonet lock on the clutch bearing allows various mounting plates to be attached, which increases the versatility of the engine test stand.

The water vortex brake is connected to the measuring shaft at the rear via a cardan shaft, and the test specimen is secured with a support device adjustable in the x, y and z axes. The engine test bench also includes a water eddy current brake (type D 2101 E from Schenck), temperature controls for oil and water and a fuel consumption measurement system.
