HI
Assuming even distribution of fuel and air in the engine, why is peak/best engine power not at peak EGT (with stoichiometric fuel to air ratio 14.7 to 1)? I was told that best power is at a slightly rich fuel to rich ratio.
If 14.7:1 gives the most efficient combustion (with no excess fuel/gas) why doesn't the engine power peak at this point.
