Actuators for Engine and Powertrain Testbeds

Powerful actuators that fulfil customer demands

Actuators are an essential part of electronic control systems in passenger cars and commercial vehicles. It is their job to convert the electrical signals from the control unit into an action. AVL offers a range of units and systems for different types of performance categories for the use of engine, transmission and powertrain testbeds. Together with the AVL automation system, complex fully automated test runs and simulations are also possible. At AVL we offer several different types of actuators:

Throttle Actuator THA 120

The THA 120 operates the throttle and injection pump on internal combustion engines. Perfect for the execution of legal driving cycles according to ECE, FTP, EPA and Japan guidelines.

The actuator of the THA 120 includes a brushless servomotor and a toothed rack actuating system with its attached FLEXBALL® cable. The power and control electronics of the THA 120 are located in a wall cabinet. The device is operated by digital and analog signals.

Key benefits include:

  • Automatic adjustment of zero and end position
  • Maintenance-free construction
  • Limitation of actuation force


Digital Clutch Actuator DCA 1000

​​​​​​​The DCA 1000 is an inexpensive solution for operating a clutch for endurance testing for manual transmissions, as well as for real idle tests on the testbed. The actuator is powered by compressed air and controlled by digital signals from the AVL control system (EMCON/ISAC). Furthermore, it’s suitable for cable-operated and hydraulic-operated clutches as well as for real clutch pedals (mechanical adaptation work required).

Key benefits include:

  • Suitable for operation of pedal, Bowden cable and hydraulic master cylinder
  • Open loop control with adjustable speed, different for opening and closing
  • ​​​​​​​Adjustable actuation range
