Engine Operation 3.5 Operating Conditions C F 0 32 As the altitude and ambient temperature rise, the density of the air tends to decrease, which affects the maximum power output of the engine, the exhaust gas quality and, in extreme cases, the starting behavior. Under transient conditions, the engine can be used at altitudes up to 1000 meters / 3400 feet and tempera- tures up to 30°C. If the engine is to operate under more severe conditions (at higher altitudes or tempe- ratures), it will be necessary to reduce the injected fuel quantity and, thus, engine power.
If you have any doubts about engine operation under these or similar conditions, ask your engine or equipment supplier whether the engine has been derated in the interests of reliability, service life and exhaust gas quality (smoke). Otherwise, contact the nearest service representative. 3 3.5.2 High Ambient Temperature, High Altitude C F 0 32 25901 1 25901 25901 1
