I'm very confused now. Is that question worded correctly?
What air:fuel mixture gives highest EGT?
a) 1:9
b) 1:1/15:1
c) cruise power
d) idle
I believe the highest EGT will be at the leanest working mixture setting, so...
a) 1:9 air:fuel is exceptionally rich!
b) 1:1 is still very rich 15:1 is relatively lean
c) cruise power (is NOT a mixture setting but, I think, my answer see below)
d) idle (is also NOT a mixture setting but the mixture needs to be fairly rich for cooling purposes)
I think I may have put
c) cruise power thinking that at cruise power I would have leaned the mixture correctly and thus would have the highest EGT!
What on earth is the answer to this one?
