Derating, mechanical governer

The engine may be operated up to 1000 m altitude and 40°C ambient air temperature
without derating. For operation at higher altitudes and temperatures the power should
be derated according to the following factors:

Altitude derating factor < 3000 m %/m 4 / 500

Altitude derating factor > 3000 m %/m 6 / 500
Ambient temperature derating factor % / °C 3 / 5°C
Humidity % No derating

Derating, electronic governer

The engine may be operated up to 1000 m altitude and 40°C ambient air temperature
without derating. For applications above 1000 m an ECU with automatic derating must
be used. For operations with air ambient temperature over 40°C, see mechanical
governor.
