Altitude testing is used to simulate high-altitude or low altitude environments, where the tested sample performs under low pressure, accompanied by low temperature and oxygen deficiency. Altitude testing systems are applied in various fields.
Engine altitude testing system, which mainly simulates the working state of the engine in high-altitude conditions, with any components outside the engine at normal pressure. This system can simulate the working status of the components that users are most concerned about, and has the characteristic of low cost.
At the same time, the altitude system can also be equipped with humidification devices to simulate negative pressure humidity conditions.
A typical altitude testing system consists of a fresh air pretreatment section, a boosting section, a temperature and humidity control section, a tail gas cooling section, exhaust fans, and noise isolation facilities.

Pressure control:
The local altitude is up to 3000m (101.3 to 67kPa), and the altitude is optional.
±0.45kPa (±50m)
When the engine operating conditions change (WHTC/ETC), there will be short-term fluctuations greater than 50 meters (0.45kPa), and it is required to return to a stable state (± 0.45kPa) within 5 seconds.
There is a pressure difference of less than 0.1kPa between the intake and exhaust.
