Climate chambers with roller benches
Simulate the real thing to validate your powertrains
Reproduce extreme driving conditions to test and validate your thermal, hybrid and electric powertrains
Faced with the diversity of energies used and changing regulations, powertrains need to be tested under precise and repeatable environmental conditions. The Emitech Group offers climatic cells with chassis dynamometers to simulate realistic driving conditions, to assess the performance and conformity of powertrains (GMP) and to validate the associated components.
These cutting-edge facilities are aimed at engineers developing propulsion systems, powertrain validation managers, test technicians and electromobility project managers, in the automotive and aeronautical sectors.
Why choose Emitech Group climate units with chassis dynamometers?
Simulate the real-life driving environment
- Reproduction of extreme climatic conditions: from -30°C to +50°C, with regulated hygrometry
- Simulation of road laws and standard cycles (WLTC, RDE, NEDC, etc.)
- Synchronised ventilation up to 130 km/h for realistic aero behaviour
Carry out customised and repeatable tests
- Cold and hot starts, transient cycles, iso-speed, thermal endurance
- Measurements of performance, consumption, emissions, ageing (DPFS, catalytic converter, etc.)
- Integration of 5-gas, particle and post-treatment analysis systems (SCR, OBD Artemis, etc.)
Adapting resources to new engines
- Motorisations thermiques (essence, diesel, gaz naturel jusqu’à 280 bar)
