Users are continuously carrying out complex development work in various environments and may not have the necessary tools or systems for consistent results. At AVL’s North American Technical Centers in Michigan and California, the needed tools and systems are readily available, providing users with consistent data and results, and the ability to duplicate testing data in their own testing environment.

With more than 60 years of experience in testing, AVL has the knowledge and ability to help resolve the most demanding testing challenges. Using equipment that is designed, engineered, and built by AVL, its technical centers have the capacity to perform a variety of tests from component level to complete powertrains.

Performance and Emissions


  • Meeting increasing demands for efficiency
  • Obtaining the proper tools and solutions to solve complex development tasks

Base development targets, such as performance, emissions, and fuel consumption, increase the complexity of development solutions for powertrains and internal combustion engine vehicles. Regardless of the testing environment, development activities need to be supported with powerful, smart tools and solutions that are consistently applied to testing methods and processes, data management and evaluations.

AVL’s Technical Centers have state-of-the-art equipment and software available for use on your next project. Use the most current edition of AVL Team Suite™ in conjunction with available combustion analysis and measurement tools to support testing environments during the verification/validation phase, including a:

  • Chassis dynamometer test rig

  • Capability to perform tests that fulfill nearly all known emission regulations worldwide
  • More than 60 years of experience in engine and vehicle certifications
  • Access to AVL solutions that have been tested and proven at numerous certification agencies throughout the world

Durability and Reliability


  • Meeting higher expectations of calculated lifetime targets by verifying powertrain durability and reliability

Product lifetime forecasting must be done before vehicles can go into mass production, and it requires a great deal of understanding. AVL’s Ann Arbor Technical Center has more than 50 staff members with an average of 15 years of experience working with various engine and vehicle types (diesel, gasoline, small passenger car, heavy duty truck, etc.). AVL’s durability and reliability knowledge doesn’t stop with its experts – it’s also embedded in its advanced simulation tools like AVL EXCITE™ and AVL FIRE™.

Supporting the tasks of durability development and fatigue strength assurance is vital during the process of creating new engines and engine components. The goal is to reduce the (1) number of warranty claims and (2) total lifecycle cost once the vehicle is launched, all with the least amount of testing as possible.

The AVL Durability Test System includes all necessary devices and system modules, as well as specific needed automation functions to support durability development with the Endurance Testing Library. AVL’s Endurance Testing Library is a built-in application library that is equipped with pre-installed test procedures typically used during the mechanical development of engines. The following test runs and library components are available:

  • Break-in test run
  • Oil-consumption test run
  • Thermo-stress test run
  • Cat-ageing test run


  • Access to the Endurance Testing Library with pre-installed test procedures 
  • AVL’s proven safety concept for engine operation
  • Robust Durability Test System to support durability development

Powertrain Calibration and Optimization


  • Meeting the demand for optimal results in a shorter amount of time
  • Keeping up with new calibration methods as tasks become more complex
  • Creating efficient calibration processes and data storage

When performing complex calibration tasks, modern software tools and methods are needed to get consistent results and meet requirements such as data quality, reproducibility, stability, and safety. As a leader in the development of high-performance tools and methods, AVL has years of experience with xCU calibration and aims to provide a complete workflow for each single calibration task. Its calibration software is proven to significantly increase efficiency by simulating real-world driving – including road conditions – in a laboratory environment.


  • Software tools that support development engineers during the entire calibration workflow, making the influence of complex xCU parameters easier to manage
  • Models that can be reused throughout the different stages of the development process
  • Full utilization of the test facility using intelligent test runs – even in unmanned 24-hour operation
  • Tools that are supported and maintained on a global scale (roll-out capability for test facilities and different locations)

Single Cylinder Engine Research


  • Finding cost-efficient methods for single cylinder engine research
  • Difficulty viewing the combustion chamber of the single cylinder research engine
  • Getting new engine developments from concept to SOP

AVL specializes in designing customer-specific single cylinder engines by incorporating individual requirements into the design with the goal to fully replicate multi-cylinder engines. This leads to a reliable transfer of test results, allowing most of the predevelopment work to be carried out on the single cylinder in a shorter amount of time.

For flow studies and combustion research, AVL Single Cylinder Engines can be converted into transparent engines with optical access through the piston and liner. Using quartz glass in the construction of the transparent engines allows for the application of UV laser systems possible. With the Engine Timing Unit, sophisticated measuring techniques, like the UV laser system, can be precisely synchronized with the single cylinder engine.

In the fuel and lube oil industry, single cylinder engines are currently being used for intake valve deposits and combustion chamber deposits tests. Here, single cylinder engines offer the ability to test future engine design features without having to wait for the production unit. A variety of single cylinder engine versions are used as screener engines for piston deposit tests with excellent correlation to multi-cylinder tests.


  • Ability to test component concepts under realistic engine conditions long before they are applied to the full engine
  • Availability of various sizes of engines, from small passenger car to heavy duty truck
  • Modular design concept allows easy conversion into customer specific engine versions
  • Versatile GDI cylinder head with highest flexibility in tumble and injector installations
  • Proven optical top-works allow the application of modern laser supported measuring techniques
