Colloidal Graphite

Lets say you have a new engine.  Clean and rust free.

6 months later its a corroded slug.

Unless, with your first application of water you add black colloidal
graphite at the rate of .5 once per gallon of fluid.

Silly little buggers coat the surfaces with an anti-oxidant coating that
does not interfere with heat flow but virtually stops the oxidation of
the metal.

Finding it is left as an exercises for the student.


-------------------------

Just for the record, CETANE Improver has long term slow FI cleaner built
in.

The colloidal graphite for engine cooling systems is sold by Malibu
Water Systems for $13.50 for 2.5 onces of 40% CG and water.  Not bad for
cooling system.  Very nice because of the extremely small size and the
molecular attraction of carbon to iron which semi-permantently
eliminates oxidation of the iron as its carbonized.

BTW, water pump lubricant is a couple of tablespoons of machinist
cutting oil blended with coloring.  A whole bottle life time supply is
about 5 to 10 bucks, depending on how wide you like to spread your
cheeks.

And "water wettner" is basic household degreasing kitchen soap.  It
foams - so what - gone in a mile.  A couple tablespoons works well and
your bimbo will never miss it.

Colloidal Graphite is the active ingredient in upper valve lubricants to
blend with the oil.  Rest is generally carriers.

Moly has been mentioned.  It does not form the same attractiveness to
iron until is been rubbed and will break down into pure moly and
sulfuric acid - great for the corrosion control of the coolant.

If you want to seriously reduce the corrosion associated with alcohol
and nitro, you may want to blend a little cg in toluene or acetone blend
with the joy juice.  Lubricates and leaves a sub microscopic film to
inhibit.  Plus the pure carbon burns very well.

Would love to find a CG source to blend with my gas-o-cruise R Fluid.

Still running the Cetane Improver.  Still loving every minute.  But, it
will not work and will not improve performance so don't bother.

"B.) Prevention of Knock. Phenomena Occurring with High Valve Overlap 

In his previously cited paper Dreyhaupt suggests the astatic fading out
of the pressure rise resulting from the spontaneous ignition of the
residual gas as a means of counteracting the obnoxious effects of knock.
Shaped piston crowns may function as knock oscillation dampers as well
as hindering any shock waves which originate from the primary flame. He
also draws attention to the large compression ratios permissible in
sleeve valve engines, presumably because of the absence of hot spots
likely to cause glow ignition knock. 

Tetraethyl lead was almost exclusively the only anti-knock material used
in practice. It was usually limited to a maximum of 0.12% vol. At one
time the question of raising the anti-knock value of 87 octane number
gasoline to 100 octane number, by the addition of methyl aniline and by
increasing the content of tetraethyl lead to 0.16% vol., was considered.
It was not found practicable, however, because of valve corrosion etc.,
caused by the increased lead concentration.  

Some experiments have been reported in which a fluid of the composition
: - Gasoline 50%, Iron Carbonyl 40%, Methyl Aniline 10%, was added to
fuel to give a concentration of 0.05% of iron carbonyl.  

Other methods, besides the addition of anti-knocks were used in Germany
to limit knocking. It is reported that coating the piston with fine
colloidal graphite gave quite good results in preventing knock. With
highly supercharged engines the D.V.L. distributed injection method was
used, in which the bulk of the fuel was injected during the compression
stroke and the combustion period. This resulted in a flattening and
considerable raising of the knock limit curve, particularly with lean
mixtures. Increases of mean effective pressure of 2-4 kg/cm2 have been
reported. "

Any wonder why someone like Judge would want to coat pistons with fine
colloidal graphite?

I knew - not in Peterson Publications.  That's your problem - not
mine....

For an investment of $13.75 it aint too much of a gamble:
