Engine Operation 3.5 Operating Conditions 3.5.2 High Ambient Temperature, High Altitude Air density decreases as altitude or ambient temperature increase. As a result of this, the engine’s maximum output, the quality of the exhaust gas, the temperature level and, in extreme cases, starting behaviour, are im- peded. Under transient conditions, the en- gine can be used at altitudes up to 1000 m and temperatures up to 30 °C. If the engine is to operate under more severe conditions (at higher altitudes or temperatures), it will be necessary to reduce the injected fuel quantity and thus, engine power.
If you have any doubts about engine opera- tion 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 DEUTZ SERVICE. © 2001 3 © 25 901 1 © 25 901 1
