that the car ,Nhead may be another OF
those things tat do not turn out as
they should.
Women who ha e difficulty getting
onto the knack of fitting gears should
try the plan of havihg an experienced
driver shift with them This can be
done by the instructor placing the left
hand on top of the driver'e right as the
latter grasps the knob of the shift lever.
In this way the instructor 9ften can
tell whether the driver is inclined to
shift too quickly or too tardily.
member that the less spinning there
is of the wheels in starting, the less
sliding there will be on stopping, be-
cause the chains will not be so likely
to break and leave the whole Job to the
tires.
Women especially should enjoy the
advantage Of a type Of accelerator pedal
that does not 60 all the way to the
floor too easily. Not only is milady more
inclined to step on it," but because she
is less intimately acquainted with en-
gineS she is not so likely to realize that
car often gets away quicker II Its
power plant Is fed less fuel Over q
rough road too timber an accelerator
also results in q jerky type of driving,
which Is as disturbing to the mechanism
of the car as 1t Is to those who ride
in it.
Some Of the newer cars are equipped
, , with hot-air heaters which draw fresh
air from just behind the radiator. In
| general, this is very healthy type OF
heating system for the car, but there
is just one precaution to be observed
This can be summed up by saying that
the heater control should be in the
closed position until the engine is
heated up.
Where cars are equipped with q
radiator shutter device, the air stream
Is blocked OF during the first few min
utes of running. If the engine back
| fires the heater will pick UP the gases
expelled through the carburetor and
transfer them to the inside OF the car
Backfiring always is greatest during
warming up.
| So wait a few minutes before start
| ing the air heater. There is no heat
available at the start anyway.
Safety isn't the only reason why driv-
ers should form the habit of getting
plan lessons the risk of parking the
car where 1t shouldn't be.
In moment of haste an experienced
woman driver tells of having parked
the car and jumped out the left side
Returning to the machine, she discov-
cred she could not open the right door
70 climb in because 1t would strike q
hre hydrant. An additional reminder
OF her mistake came in the form of a
small but significant tag attached to
the steering wheel
Women who register their own cars
near a lot about piston displacement
put unless some obliging youth is on
hand to figure it out for them they
are apt to remain baffled by the mystery
OF the term. Displacement, however
is not only simple matter to under
stand, but one that helps to under
stand what makes the car tick.
Displacement simply is the cubic di-
mension of the cylinders, considering
them as whole. If the diameter OF
a cylinder Is inches and its piston
travels 4 inches from top to bottom II
is a matter Of simple arithmetic to
figure out the total number Of cubic
inches OF displacement for the indivi-
dual cylinder or for the total number
OF cylinders of the engine.
TneSe dimensions give the rough basis
OF determining the power Of an engine
An engine with displacement of 4OC
Is more powerful than one of only 200
but when the figures are closer together
tney are less OF a guide to the power
output because number of other points
must be considered. Some engines car
run faster than others, and speed with
an automobile engine always increases
power. In addition, the special features
OF design play very important role in
determining just what an engine will
be able to do. This explains why many
engines with relatively small piston dis.
placements do surprising amount Of
work.
Motoring experiences have a neat WAY
