citation needed. I could see an engine using more fuel per unit power at a lower power level but not less fuel overall.
If they did you would just run the engine at 80% all the time and waste the excess in a massive water brake or resistor bank.
- brianwawok 8y agoI am sure it is per unit. Means you are better off to run it at high load and battery the excess power, then shut the whole thing off for a bit, vs run it at 50% all the time.
- cryptonector 8y agoIf you have two engines you could be running at 40% each, or shut one down and run the other at 80%, it will be more efficient to do the latter (unless you have to be able to start the idle one quickly and that's not possible if it's at 0%, so then you run one at 75% and the other at 5%).
