There might be more point to the
recent report that 40 per cent OF the
cars are bought by women II 1t could
pe added that only 81 per cent Of the
cars are paid for by men.
Sitting at the wheel of an extremely
low car isn't so pleasant when you're
trying to park. but has 1t ever occur q
TO you that the way to tell how close
the car il to the curb Is simply to note
II the left side lines up with the ma
chimes parked ahead or behind?
How q battery that M rated at only
6 volta can provide high voltage for
ignition Is q matter that may we'll
puzzle the woman who Is interested IN
the mechanical unctiUning OF her car
Here. then. is where an Introduction to
the coil is apropos.
This part cons lists OF q core surround
ed Wy two separate windingS OF insu-
lated wire Because VI the principle OF
induction 1t Is possible 10 feed low volt
age ~ the primary wiring and obtain
high voltage from the secondary wren
the current Is interrupted in the :or-
Iner. On This break" OF the current
voltage Suff1cient to throw spark ut
the plugs Is obtained In the secondary
circuit.
That. briefly. Is the foundatio of the
ignition system. OF course, In gaining
voltage for spark purposes we lost am
perase for electrical work. That is why
there Is no coil In the circuit to the
self-starter.
II you are still listed among the he
sinners. you probably are having your
Share OF trouble wondering whether
your Instructor means that YOU should
press on the clutch pedal or release 1t
when he says TO let It out" This has
confused more students OF driving tran
any other single point know OF.
Yet 1t can be simplihed by 'sing
different terms. Suggest to your in
structor that he order you to "declutch'
when he means pressing the pedal to
the fioor and clutch" when he wants
you to let the pedal come back to It's
normal position. We don't say press
the brake pedal out when ordering
stop, but simply command stop"
Saying "declutch" means TO do with
the clutch pedal just what one would
do with the brake pedal when told 20
stop
II you are one Of those who are made
miserable when learning to drive by
thinking that every one Is CARING at
YOU. 1t may be some consolation TO
know that most people LOOK around
largely with the idea of inviting tnspec-
ton There are focks OF new cars to
be admired. you know, not to mention
the new hats.
In your experience in driving you
may have noticed that when the car
IL Obliged to climb o particularly steep
part OF the road 1t often falters. even
il the engine Is given all the gas the
throttle will admit. Why doesn't the
engine respond under such conditions?

There are two reasons. In the nrft
place. q gasoline engine depends upon
It's speed for Its power rather then on
the amount VI gas that Is fed to II. In
this respect IT. differs from the steam
engine, which Is dependent ;uIon the
amount Of steam pressure avaiaole Tor
the work 1t will do. When the gas en-
sine fails Ia one speed we have t. gear
it down make 1t run faster In piopor-
ton TO the speed of the rear wheels)
In order 10 get power from 1t.
The second reason also has to DO
with engine speed, but from q different
standpoint. Gas vapor does not rise
from the Carburetor in any great guam
tity OF its own free will. The suction
of the pistons does this. Thus. even II
the throttle Is wide open. the engine
doesn't get much gas II 1t Is running
slowly.
The man ct the filling station should
be asked to be careful when he places
the hose nozzle In the gas tank. other
wise he will be apt to spill over the
back Of the body any gasoline that mey
still be In the hose. Many owners are
for the attendant to drain the hose.
In addition to protecting the finish on
the car, therefore, you can make use
of some Of the gas the other feilow
wastes.
1t should be entirely fair to tell one
OH the gentlemen who have Depn driv-
Ing cars long enough to know q thing
Or twO, especially when 1t points
moral. Consider, therefore. the driver
with . fiat tire who decided that ne
would continue to spin even though he
did net toll by changing TO the spare.
He knew he was running b rear tire.
but he did not realize that he was also
increasing gas consumption. The ear
dragged along with its Hopping tire
and had TO take each hill In low gear.
And then he ran out OF gas!
Experience demonstrates that one has
to be very clever to abuse any part OF |
a ear and get by with it.
Some Of these days 1t may be reces-
sary to lift the hood to explore with
the idea Of locating a strange noise.
When and II this happens, ,-or't make
the mistake Of just letting the engine
idle. Speed 1t up for the test. as 1t
will perform differently when more
active.
For instance, the fan blades may be
striking something at the front OF the
motor. but only when the engine runs
fast. because the fan often changes rs |
position when IL speeds up.
