Well thx for clearing that up for me aerohead.
I'd never have guessed that the H in HCs combines with the O2 in air to form water in one form or another in an engine otherwise!


No!? What about teleportation!? As in "Beam me down Scotty!" I saw it in Star Trek so it's definitely possible!


The crankcase is sealingly and slidingly disconnected from the crankcase by said piston rings.

The crankcase breather of most all engines exhausts into the engine intake, not the exhaust.

So the only way for crankcase water to end up in the exhaust is by;
  • boiling/evaporating out of the oil-water emulsion in the crankcase and leaving via the crankcase breather system, into the intake.
  • then going through the engine with the intake mixture and being blown out the exhaust valves and ultimately the tailpipe.
If
the amount of water in the crankcase is very small, as asserted, wouldn't the bulk of the water coming out the exhaust be from the combining of H and O as you asserted earlier..?

The fact that the steam has cooled to below the condensation point on cold mornings merely makes the water formed during combustion visible on cold mornings.
It's still there during the heat of a summer day, you just don't see it because it hasn't condensed at or around the point of leaving the tailpipe.



Quite so!
Now suppose you're a mad scientist like me. (NOT to be confused with a stupid scientist... )
Being a scientist ; you discover that by dissolving a certain substance (Boric Oxide say) in the water before putting it in contact with metals has the following effects:
  • The acid to forms an extremely hard (85% the hardness of diamond), extremely wear resistant ceramic surface on the metal.
  • Said ceramic surface is also extremely resistant to attack by other acids, effectively shielding the metal underneath from any further attack by them, stopping the erosion normally seen by the acids formed from combustion in its tracks, including further attack by your acid itself.
  • Said surface transitions from this hard ceramic layer to a layer with 70X less friction than previous lubricants at a distance of around 0.5 microns form the ceramic side.

What do you do with your new found discovery?
Do you decide that;
  • Despite the evidence you have carefully collected by following research protocols and seen with your own eyes, the results are too good to be true and therefore to be dismissed without another thought?
  • Come to the conclusion that you have stumbled upon a major discovery that will change the lubrication industry for ever... IF you can convince engine etc makers that they want to produce engines etc that never wear out, cutting their profits to a 10th of what they currently are.

Yet the piping used in crankcase breather systems is never smaller than an ID of around 6mm. Why not use 'statistically insignificant' oil pressure gauge pipe with an ID of under 0.5 mm instead? It'll be cheaper...

The blowby per stroke is 'statistically insignificant', but considering there are around 3000 of them every minute in your running car things may add up to the point where you want to change the oil quite often..?

You would do well to stop treating me like an idiot. What does this look like to other forum members..?
1) All cylinder bore bottom openings share the same space as the crankcase.
2) During combustion, the pressure of the exploding charge and it's gases are available to crankcase if piston ring blowby exists.
3) The water vapor in the gases will condense into liquid water upon experiencing dewpoint temperature, creating 'sludge.'
4) Your writing lacks the specificity of the 'technical writing' which would never leave the reader wondering what level of command of the topic you were in possession of.
5) Whether you realize it or not, your arguments seem to be a form of 'disputation', rather than logic, in which getting to the 'facts' is not the real premise, just 'winning' the argument, at all cost.
6) Yes, the positive crankcase ventilation system ( PCV valve ) dumps into the airbox, ahead of the air cleaner.
7) If crankcase 'water' is entering the exhaust, it's only pathway will be via the PCV valve, as water vapor.
8) Yes, the exhaust stroke evacuates the waste gases, which is mostly Nitrogen, plus water vapor, and incomplete products of combustion.

9) Okay, you've dissolved 'Boric Oxide'? or 'Boric Acid' in water, to create a water-soluble solution. Need clarification before we proceed.
( the internet is ambiguous about this ).
