cooling system. 1t retains this
heat until later in the stroke,
when 1t releases it, after the first
fervid heat of combustion has
passed This withheld heat finds
the piston part way down in its
stroke when the first force Of the
impact OF the exploding charge is
gone and adds its force to speed
the descending piston. Briefly
then, the water acts as a sort OF
power storer. absorbing a certain
quantity OF heat, that is power,
carly in the stroke and releasing
IL later on just when II can do the
most good. No wonder then that
the driver notices an increase in
power after a vaporizer has been
fitted to his engine.
The friends OF vaporized fuel
feed claim also that their favorite
device will de-carboniZe any mo-
tor and keep 1t decarbonized.
Frankly, I have never seen any
proof that would convince me that
a vaporizer could loosen and blow
out firmly rooted carbon deposits.
When carbon is once firmly settled

steam or anything else except
elbow grease and a seraper can
remove II satisfactorily. / think
II is possible that when a vapor-
iZer is fitted to an engine that has
a light deposit of carbon. one
which has not yet had time to get
the fiint-like consistency that the
heavSN de eposists assume, 1t may
loosen the soft carbon. so that all
or much OF It may be driven out
OF the exhaust. This is possible,
though I have never had actual
verihcation OF IL. On the other
hand. I do feel fairly certain that
when a vaporizer is installed on a
clean engine 1t will prevent future
carbonization. Therefore, I would
advise anyone fitting a device of
this sort to have the cylinders
thoroughly cleaned OF carbon and
then put on the vaporizer. In
those circumstances the car own
er's carbon troubles will very like
ly be at an end.
! have noticed statements made
by car owners who claimed that
the addition of a vaporiZer stopped
chronic cases of pre-ignition and
knocking. This may very probably
be entirely true, and yet 1t would
not mean that the water device had.
cleaned the cylinders OF all carbon.
II the water and steam carried
away the outstanding particles OF
carbon, those tiny flakes that get
red hot during combustion and re-
tain their glowing hent long enough
TO fire the incoming charge, the
troubles mentioned would be reme-
died, and yet the motor would
have its basic deposits of carbon.
have noticed a number of ques-
tions asked in regard to why water
fed by a vaporizer is beneficial,
whereas water in the gasolene tank
will play havoc. with the whole
operation of the engine. The rea-
son for that is simple. II water is
put in the fuel tank II passes down
through the fuel system and enters
the carburetor. Now the opening
in the carburetor is adapted to
handling gasolene, which is a very
much finer liquid than water. That
is to say the minute globules that
make up the fluid We call Saso-
lene are much smaller than those
comprised in water.
Therefore. the the water will not
pass through the minute orifice de-
signed to admit the conventional
motor fuel. The drop of water
forms a barrier at the carburetor
tube, and the flow of fuel to the
cylinders is interrupted. In the
case OF the vaporizer the water is
fed in after the gasolene has been
passed through the carburetor and
is in the form of a spray. ready
. for combustion. This spray is
| met by the water which is flashed
into steam and the two mlngle,
with only beneficial effects.
It has long been a practice OF
| kerosene engine drivers to inject
little water in the inlet mani
folds of their engines. Perhaps
our vaporizer designers got the
idea from this practice. At any
rate we are certainly justified
in saying that the installation OF
a vaporizing apparatus will in
crease the power OF an engine, will
| give more miles per gallon of fuel,
md will certainly not have a bad
effect on the matter OF carboniza-
tion. In other words, there is moth
ing to be said against the use OF
such devices and there is much IN
their favor.
