Tie eject of incorrect wiring on the
motor depends on how the wires are
misplaced For instance, II the high
| tension cables were changed around so
| that NO one of them went TO the right
plug 1t would be impossible to run the
motor, although an occasional explo-
| sion might be obtained. II two Or
three of the high tension wires were
| interchanged, but one or more were
| left on the. correct plugs, then the
motor would run on the scylinders
in which the latter were. Where
dual system Is employed the wires OF
battery system may sometimes be
misplaced without interfering with the
| operatfon of the magnetic and vice
versa. AS a rule. however, the chang
ing of the wires will result in the
whole ignition system becoming mop
eratlye.
Does an engine deliver more or less
power to wheels with friction trans
mission and chain drive than through
the ordinary bevel gears?
The efflciencies of the sliding gear
set with the shaft drive and the fr1c-
ton transmission with chain drive are
approximately equal on the higher
gear ratios. but when the friction
wheel is brought near the center OF
the disk the slippage of the inside
edge of the wheel. due to the small
circle it is travelling on, causes pow
err loss that is greater than when the
low gear OF the sliding gear set is en-
gagged.
Assuming that an automobile stands
in a garage so per cent out Of each
twenty- four hours, what would pc the
saving in casing expenso providing the
car was put on jacks and kept of the
tires during the time 1t was not In user
The amount of money you might
save by jacking up the wheels when
the car is not In use is too small TO be
measured, providing there In no oil or
water on the garage floor that might
cause the rubber to deteriorate The
reduction in pressure and consequent
lessened strain on the castings when
this Is done is almost infnitesimal, al
though 1t Is popularity supposed that
relieving the tires from the burden OF
supporting the car must necessarily
relieve them from just that much
strain and that therefore they will
wear longer If the car is lacked up.
The reduction in pressure when this Is
done is exactly inversely proportional
to the increase In volume OF the tube.
When the tire is supporting the car
weight 1t fattens slightly and one
might say. imperoeptibly. IL the tires
are pumped up as hard as they should
be. The lattening of the tire causes
small decrease in the volume OF the air
in the tube and therefore when the tire
is raised on the ground it regains its
normal shape and normal volume. 1t
is obvious that this small change in
volume will not affect the pressure to
INV extent, since the decrease in pres
sure is inversely proportional to the in
crease In volume. And since the de-
crease in pressure is almost fncom-
mensura BILE the lessened strain and
consequent saving In tire cost is meal
culable.
Is there any good preparation for poll
ishina the body of an automobile which
will not harm tho varnish or paint?
It is not advisable to use polish OF
any sort on the body II the finish has
become dull have the body reyarnished.
The only rejuvenator worthy OF con-
sideration Is soap and water, and some
body makers condemn the soap, adVis-
ing the use of water only. However.
there is little harm in using lukewarm
water and soap, provided the soap Is
not too strong. In cleaning the body
first wash the dust of with hose and
do not apply n sponge or cloth until
the dust has been removed and the
mud softened. Then sponge the body
with soap and water and finally rinse
with a hose until the soapy water has
been entirely removed. Then wipe dry
with chamois. If this advice is fo-
lowed there will be no need of using
any body polish, as the varnish Will
hold its luster almost indefinitely.
The brake on my car has been drag
ainn for some time. viii this cause
the tire to wear moro raPidiyf
Inasmuch as the dragging brake re-
tards the free movement of the wheel,
the tire is made to wear out more
! quickly than normally. Especially is
/ this so when the brake Is applied. The
principal detrime1lt, however. lies In
the increased work imposed on the mo-
tor, which causes it to heat quickly.
Our car has a unit power plant US
/ inc one grade OF DIV for crank CASE
multiple disk clutch and gear set. The
oilina system 10 circulating splash with
pump. Can we use graphite In our
| power plant? If SO, how much sra.
phite TO the gallon of cylinder oil, and
what make7 s-.s
Use one teaspoonful of fake graphite
TO each quart of oil. Do not throw
the graphite in loose. but mix it into
n soft paste first and,t then add 1t to the
oil. In buying the graphite be careful
to obtain n good motor graphite as
aome graphites are not suited for motor
/ iubrieatton. Some are too coarse.
others to fine and some contain grit.
