Applus+ Laboratories performs thermal fatigue tests on components at extreme temperatures to streamline product development and ensure production quality.

Gas emissions is a key indicator for any type of vehicle, from commercial cars to motorbikes, trucks and heavy-duty vehicles. Improving the performance of the Exhaust Gas Recirculation (EGR) and Exhaust Gas systems helps cut emissions and improve combustion engines’ performance. The hot gas test bench, developed by Applus+, provides a laboratory environment that simulates thermal fatigue on vehicle components working with exhaust gases at extreme temperatures. The bench includes controlled cooling circuits to test EGR coolers and similar components. 
Our engineers help clients to validate their prototypes in development stages and conduct production quality control tests. At the Applus+ thermal testing center, we perform thermal cycles on the following components, amongst others: 

EGR Systems

1. EGR Coolers 
2. EGR Valves (based on demand)

Exhaust Gas Systems

3. Exhaust Manifolds
4. Pipes, Clamps, etc.
5. Catalytic Converters  
6. Exhaust Mufflers
