Mechanical Engineering
Derating is also a term in mechanical engineering when engines are intentionally operated at less than maximal output. Someone that knows more about this than me should update the article, but I believe that this is often done to extend service life or reliability. Fawcett5 18:26, 31 August 2006 (UTC)
Derating image
The image of a hypothetical derating curve for a BJT would fall linearly at -1-1/3 W/degree C if the highest temperature mark is changed from 75 to 85 degrees. There is no reason to imply a change in slope above 65 degrees which is not typical nor shown in the reference. Cuddlyable3 (talk) 10:07, 26 May 2009 (UTC)
Definition
This article is not helpful! We can all guess that the word "derating" means that the engine is "rated" for less horsepower. The question is, how do they do that? In an aircraft engine, for example, do they restrict the throttle or fuel flow? Do they re-pitch a propeller? Redesign the intake system? EXACTLY, what is done to derate an engine? Is it just an RPM limitation without any modification of the engine? — Preceding unsigned comment added by 98.170.203.140 (talk) 23:53, 16 June 2011 (UTC)
Power devices also derate with frequency
Power devices are specified up to a maximum operating frequency, beyond which the dissipated power must be reduced. 2001:8A0:5E5A:EE01:6D29:FB47:452B:45 (talk) 17:11, 25 August 2023 (UTC)
