The holistic AVL quality assurance concept considers assembly and production boundary conditions, and delivers a complete system solution for ensuring best-in-class engine and process quality verification. This includes a complete set of testing technology platforms for process and test automation.
It includes in-process verification during engine assembly, functional test after assembly (EOL cold test) and performance tests after assembly (EOL hot test, quality audit / conformity of production test). The solution portfolio for gasoline, diesel, and compressed natural gas (CNG) engines is branded by AVL Engine TS™ EOL Hot and includes:
- EOL Hot: End-of-line loaded hot test systems
- QA/COP: Quality audit / conformity of production test systems
- Qualified Hot: Hot test systems for EOL HOT and QA/COP test
The test systems involve AVL and third-party products and services (e.g. in-house/in-cell integration, enclosures, or complete containerized solutions). Our on-time guaranteed testing capacity ensures strict adherence to standard operating procedures (SOP). With robust hardware and software, we maximize system availability, ensuring that our operations run smoothly and efficiently.
Our flexible and integratable test systems safeguard a 100% stable production process, providing reliability and consistency. Additionally, our accurate, best-in-class test data at the R&D level instills the highest confidence in our test results.

At AVL, we see our production testing solutions as an important factor for both an effective production process and high product quality – a major pillar our customers can rely on.”
