// Internal Combusion Engines
With us, your combustion engines show off how efficient and low-emission they are. We provide you with the data to prove it.
Our extensive experience in engine testing and the processes secured in practice have one main effect: our engineers develop new engine technologies and are provided with the optimum basis for efficient testing. This ensures the greatest possible satisfaction for our customers.
We also work on test topics such as:
- Endurance and functional tests of combustion engines with different fuel types in simulated vehicle environments — using real-world driving profiles
- Exhaust aftertreatment on test benches (with exhaust system layout precisely as in the vehicle)
- Motor mechanics
- Thermodynamics, heat balances
- Soot and fuel ingress measurements in engine oil; highly flexible fuel management ensures the right fuel
- Tilt tests for the optimisation of oil circuit and blow-by system
- Certifications
- Quality assurance of your series production through CoP (Conformity of Production)
For us, processing quality and efficiency go hand in hand
Efficient processing is ensured by an all-round service that starts with collection at your desk and is guaranteed by continuous operation — via 3‑shift operation 365 days a year.
