EVERY man HAS
HIS IDEA ABOUT
CARBON TROUBLE
Plain Kerosene Appears To
Be About the Best Dose
For Its Removal

Zach man who owns an automobile
has his own ideas about carbon pre-
vention and removal, but not all OF
them are by any means correct. This
substance Is deposited in the com
bustion chambers Of the gasoline en-
Rine through imperfect combustion OF
the cylinder oil and gasoline. Dust is
drawn into the motor and adheFeg &c
the first Oily surface II strikes. adj -
ing to the accumulation of the piston
head. Eventually this deposit be-
comes so deep that 1t is incandescent,
causing premature ignition Of the
fuel. It is this latter characteristic
which makes IL so important to set
rid Of the carbon.
This substance may DO scraped out
with specially designed tools with
most engines, which permit a pretty
Thorough job to be engineered with
out removing the cylinder head. There
are several sorts Of chemical carbon
removers on the market which are to
he injected into the combustion cham
lber for the purpose Of loosening the
carbon and permitting IL to be blown
out Of the exhaust. With some types
OF motors It is possible to drop a small
chain I'm the combustion chamber
and let II scrape the carbon auto
Ematically as 1t flies about under the
Itmpulses Of the piston.
After many experiments, It has been
found that the one best bet as a car
bon remover Is a dose Of ordinary
kerosene, properly administered,
When the engine is hot at the end Of
the days run, feed about three or
Your ounces. say, a third Of an Ordi-
mary drinking glass of kerosene
Through the air-vent on the intake
manifold, or through the air intake Of
the Carburetor While the engine IS
adling.
The kerosene should be poured in
gradually and the throttle should be
opened very slowly and the engine he
Bpeeded up on the kerosene, which is
thus drawn into the cylinders in lar
ger quantities than can be vaporized
and burned at once and in a few min
tutes the excess kerosene is being
Ichurned up and down in the cyliu-
.ders. soaking the valve seats and the
Epark plugs
That there is a surplus Of the kero-
Bsne in the cylinders may be proven
aby the fact that the engine will run
at good speed for several minutes
after the operator has stopped pour
Ing the oil into the intake manifold.
After running the engine for some
minutes on the kerosene fuel, it
should be rapidly speeded up by open
9ng the air-vent wider and then, while
Che kerosene Is still being poured in
10 the manifold, the spark should be
shut off. More kerosene is drawn
into the cylinders with each revolu-
Elon and none Of It rs burned up, and
9t may be left for the night to per-
eorm its function of a carbon solvent
pn the cylinder head, valve seats and
pluga-
ls Not the Best Way.
( Many car owners inject the kero-
sone through the pet-coclIs, but the
method described above has the ad-
vantage Of a uniform application to
The valves. When the oil Is put in
by way Of the pet-coclls, It is likely
20 run down one side Of the valve and
removes only a part Of the carbon de-
postt, leaving the other side untouch-
ad and ready for It's old mischief
AS with other things, prevention Is
better than cure Of carbon troubles
