AVL Single Cylinder and Components Test Systems_1

AVL Single Cylinder and Components Test Systems

AVL test systems are available for testing single cylinder research engines, engine/powertrain/vehicle components such as gearboxes/differentials/valvetrains, KERS systems, brake systems, oil/water/fuel systems.

AVL Approach

The AVL Single Cylinder Testbeds are carefully designed to ensure a wide operating range and the high measurement quality needed when doing power development on single cylinder research engines. Driveshaft design and torque measurement selection is done with the experience of AVL in supplying such test systems to our racing customers.

The AVL Components Testbeds provide a flexible platform for testing any kind of powertrain component. The mechanic design and dyno selection is done according to the particular requirement to maximize the utility. Auxiliary systems as oil/water conditioning systems provide suitable media supply to the test specimen if needed. A battery simulator/battery tester are used when testing KERS components.

The AVL Dynamic Brake Testbed with integrated windspeed-simulation has all the features required for dedicated brake R&D, performance and durability testing under realistic conditions.

The AVL PUMA OpenTM Components Testing System provides the power and flexibility in data acquisition and test automation needed on these kinds of testbeds. It integrates seamlessly into the world of parameter management and result data storage with any other AVL testbed.

Benefits at a Glance

  • Custom specific test systems tailored to the particular need, made out of well-proven standard components
  • Automation system with a similar look and feel as standard across all AVL engine/powertrain testbeds ensures homogeneity in operation, data handling and the minimization of training efforts
  • Interchangeable data acquisition modules with AVL engine/powertrain testbeds guarantees identical high measurement quality, same calibration procedures and common spare parts
