Planning of a quattro altitude test chamber

Altitude simulation chamber for development and certification measurements

The measurements are carried out with the whole vehicle placed on a roller dynamometer. Constant climate conditions are necessary for the exhaust gas and development measurements.

Control room

In the control room (located inside the pressure chamber) the test stand is operated from and the test results are evaluated there.

Analysis room

This room contains the complete exhaust gas measuring technology (diesel tunnel, analysis cabinets, CVS tunnel).

Sluice

The sluice (placed within the pressure chamber) is access and exit to the pressure chamber. It generates the pressure equalization between the simulated altitude in the pressure chamber and the local ambient pressure.

Technical features

Air pressure range: at normal altitude up to 600 hPa, max. ±2 hPa

Temperature range: -20 to +60°C, ± 1K

Humidity range: 10 to 95% r. F, ± 5%

Dew point range: -20 to 48°C
