Dumbed down doesn't begin to cover it - your explanation is about as dumb as
they come. Where in the world did you get that stupid idea about the
injectors wetting the inside of the intake? You can't be that grossly
ignorant of basic fuel system operation. You must know injectors produce a
fine mist, and that if the injectors don't do that they have to be cleaned
or replaced. How could you not know that the manifold is a wind tunnel at
that point, which makes it impossible for the manifold to collect gasoline?
Have you *ever* flow and pattern tested a fuel injector? No, you obviously
haven't - you wouldn't parade your ignorance if you had ever seen it with
your own eyes. That is to say nothing of the ludicrous concept that the
gasoline vapors would pour past the closed throttle plate and through the
air filter and intake plumbing to create the "strong smell" the OP reported.
I'm sure you will favor us with the equations for your "physics" for all
that - you are bragging you understand all that. You can even "dumb it down"
by leaving out the partial pressures of the more volatile components of the
winter blend being used and assume it is all octane. It isn't even all that
hard - by estimating the cross-section of the intake manifold branches and
using the known displacement and idle RPMs you can calculate the peak and
average air velocities past the injectors. With your superior knowledge of
physics I'm sure you can calculate the average particle size of the injector
output for the rated rail pressure and the fluid flow equations for the
dispersal in the intake, including the lateral displacement of the plume in
the previously calculated air stream. You can also calculate the diffusion
past the obstacles I mentioned (you can assume a 500 millibar drop across
the throttle plate at idle - it will be close enough for this purpose and
will allow you to estimate the effective throttle opening at idle) to arrive
at the vapor outflow rate at the mouth of the intake. Otherwise stop with
your bogus claim of "physics." If you nail the equations I won't even take
exception at your petty insults. Otherwise we will know you are a loudmouth
know-nothing... as if we really doubted it now.
Put up or shut up.

oh brother - where do we start with you michael? how about we start
with the fact that gasoline is liquid. it takes time and energy to
evaporate. add air to the mix, and the evaporation rate changes. and
if it's sprayed onto cold metal, which it is until the engine warms up,
a significant portion /remains/ liquid. that's why injection runs rich
on cold engines. if it didn't, there'd be no need to do that!

translate pressure drop into evaporation at ambient. show the cooling

Stop waffling and show us the math. You claim the atmosphere is condensing,
which is contrary to the entire point of electronic fuel injection (if it is
condensing, the indefinite lag makes control of the mixture impossible). In
your fantasy world a carburetor would work every bit as well; just shove
gasoline down its throat and the engine runs when cold. You call it
"physics", so I want to see it. It's your screwball theory - defend it or
stop spouting nonsense. So far, everything you have asserted has only
illuminated your ignorance of automotive basics. If your vision of "spraying
the gasoline onto cold metal" were accurate the engine would already be
flooded, as anybody who has dealt with a flooded engine knows.
You seem to have no idea what "rich" means in this context. The problem is
one of producing a combustible mixture at the plug in spite of the lower
vapor pressures at lower temperatures. To do that the mixture is shifted
toward the rich end, but there is not a lot of margin for movement; if the
mixture goes above 13.1:1 (from the nominal 14.7:1
en.wikipedia.org/wiki/Stoichiometry) it won't burn - the engine is flooded.
From "The Physics Factbook" at
hypertextbook.com/facts/2003/ShaniChristopher.shtml "The mixture cannot burn
when it contains more than 7.6% gasoline because it is too rich to burn."
Ideal 6.8%, maximum 7.6%, or no more than an extra 12% or the engine
floods - that is what "rich" means in a gasoline engine.
I'm still waiting for the physics you claim, professor, not hand waving
arguments. You are still off on that garbage about the injectors "spraying
onto cold metal" - which is strange, since you claim to have flow and
pattern tested injectors; you would not think such a stupid thing if you
even understood the significance of the pattern. You have not offered even
an explanation how the injector output, even if it were a stream, would end
up on the intake wall instead of being summarily sucked into the cylinders
as it must be for EFI to operate.

Jim, why is it that damn near every thread you wade into becomes a
shitstorm? You are the only person who routinely gets involved in
mudslinging of this sort. Everyone else shares their opinion without
judgment, and we usually get along just fine. What's your problem?

now let's see:
1. i explain the wetting situation, but the drama queen goes nuclear
with "if tomorrow the OP reports a fire that destroys his Fit and
possibly his home".
2. i cite a text book corroborating precisely what i explained, but
based on the above, it's apparently too hard to understand.
and yet i am the one with the problem! ridiculous.

So in answer to my question, after four opportunities you can *not* present
the "physics" you have been babbling about. You are a fraud.
You aren't keeping up with the subject at all. Your points were disproven by
the source you cited as detailed in the last post (did you even read the
page you posted?) You haven't tried to explain how the remnant of vapor in
the manifold is supposed to get out, or quantify the amount in the manifold,
or answer *any* relevant question posed. You ridiculed the evaluation of a
professional, just because you didn't like what he had to say. Your myth is
busted but you still think you must save face rather than admit an error
like normal people do.
You are indeed the one with the problems - you are unable to keep up with
even this simple subject, instead rambling and blustering with every post,
just as you did this time. You use bullying taunts (as you just did again)
to try to deflect examination of your errors - an even uglier problem that
does not speak well of your present mental capacity. Those are really huge
problems you have. I hope you are just drunk when you post, because it is
really sad to think of you having those deficiencies when sober. Take care
of yourself.

There is a difference between the smell of RAW gasoline and partly
burned exhaust fumes that go through a cold converter that doesn't
clean them up. I think the OP was smelling the latter.
I think some of you have been on a wild goose chase for quite awhile.
