altitude de-rate on diesel engine

altitude de-rate on diesel engine

(OP)
what would the de-rate be for a diesel engine running on 180cst hfo be at 1200M above sea level

RE: altitude de-rate on diesel engine

depends on the engine.  some HFO-capable engines can operate at 1200m+ without altitude derate.

 

RE: altitude de-rate on diesel engine

Per Cat's installation info:

"Altitude Derating - Each model and rating has established
maximum altitude capabilities for lug and for nonlug applications. For higher altitude operation, power settings must be reduced approximately 3% per 1000 ft (305 m) above
the altitude limit for that rating. Diesel engines do not self-derate enough so that the fuel setting can be left unchanged. If they are not reset to appropriate power levels,
naturally aspirated engines may smoke badly and turbocharged engines may suffer excessive thermal and mechanical loading,
resulting in internal damage, without giving external indication of distress."
