why lean burn heats up..
Well I am not sure that more fuel will burn faster than
less fuel. One would expect a smaller amount of fuel
to burn faster than a larger amount.
If what you are saying is that in a lean burn combustion
the fuel is burnt quicker so there's time to spare after
for heat transfer to the metal then sure, that's logical.
It all comes back to the same thing and that is that
too much fuel is going in and too much heat is being
generated.
So it may well be that what we consider 'lean' is
still way to 'rich'.
I like what others are talking about in only running
lean under certain conditions. It makes sense to me
to be changing from lean to stoic and back on the
fly according to different factors.
