3.5. Operating Conditions
The following information pertains to the operating conditions that your DEUTZ engine
may be in.
3.5.1. High Ambient Temperature and Altitude
As the ambient temperature and/or altitude increases the air density decreases. As a
result, the following engine characteristics will be IMPAIRED:
• Engine maximum output
• Exhaust gas quality
• Increased Coolant temperature
• Starting behavior (in extreme cases):
The Engine can be used at altitudes up to 91m (300ft) and temperatures up to 25°C
(77°F) without a decrease in performance. If the engine is to be used at higher altitudes
and temperatures then the amount of injected fuel must be REDUCED. This will
DECREASE engine power per NFPA regulations as follows:
• Deduct 1% for each 100m (328 ft) above 91 m (300 ft)
• Deduct 1% for each 5.6°C (10°F) above 25°C (77°F)
If you have any doubts about the operation of your engine under these or similar
conditions, ask your equipment supplier. Otherwise please contact DEUTZ SERVICE.
