Why carry out airflow testing?
Wind tunnel tests are essential for :
- Precisely characterise the permeability of components such as cylinder heads, catalytic converters and particulate filters (DPFs).
- Accurately measure internal air movements such as Tumble and Swirl, which are essential for optimising engine efficiency.
- Accurately detect and quantify leaks using Helium measurements, to guarantee component integrity.
- Validate aerodynamic design to improve overall engine performance.
High-precision equipment
Our laboratory has high-performance equipment for accurate and reliable testing:
- Automated test benches for precise, reproducible measurements.
- ABB Sensiflow massflowmeters for accurate airflow measurement (up to 1300 kg/h).
- Advanced measurement systems for detailed characterization of component aerodynamic behavior.
Our resources dedicated to airflow testing
The Emitech Group has a laboratory equipped with high-performance wind tunnel test benches enabling it to carry out a wide range of specialised tests.
Cylinder head permeability characterization
Our tests enable us to accurately measure the permeability of cylinder heads and assess their efficiency in terms of air flow. This makes it possible to quickly detect points of loss or resistance to flow, and thus improve the engine's overall efficiency.
Tumble and Swirl measurement
Tumble (vertical vortex) and swirl (horizontal vortex) measurements are essential for characterizing and optimizing the engine's internal flow dynamics:
- Optimising combustion and energy efficiency.
- Reducing pollutant emissions.
- Improving torque and engine power.

Permeability measurement of catalysts and DPFS
Our wind tunnel tests include precise measurements of the permeability of catalytic converters and particulate filters, essential elements in the control of pollutant emissions. These tests enable :
- Validate the efficiency of filtration and catalysis.
- Optimise the performance of post-treatment systems.
- Guarantee compliance with environmental standards.
Helium leak measurement
We use the advanced Helium leak measurement technique to accurately detect and quantify leaks on various components:
- Validation of the tightness of critical systems.
- Quality assurance of manufacturing processes.
- Proactive prevention of in-service failures.
