1t is important in these hot weather
days for the automobiles to take
especially good care of the carburetor
In his car. This should be done in
addition to giving special considera-
ton to hot weather tire expansion and
overheating the engine.
1t will be found usually that not
quite so much gasoline is required in
hot weather as during the winter
months. Therefore, the dash adjust
ncnt may be carried little nearer the
lean, or air, side. This not only saves
gasoline but increases the power of
the motor. for too heavy mixture
makes it run logy.
Also it will be found that in most
cases the hot air stove of the carbure-
tor may be dispensed with or adjusted.
usually provision is made on the hot
ar stoves for allowing some cold air
u enter or to take cold air entirely.
Where the carburetor is water Jacket
ed there usually is valve that may
be closed to prevent the flow of hot
water. Experiment will determine
whether it is advisable to cut out the
heat entirely on the individual car
buretor, since all are not benefited by
TIE change.
=. Then, too, the water in the storage
battery will evaporate more quickly
IN hot weather than in cold Where it
has been necessary to replenish it once
In two weeks in the winter it will
need to be done every week in hot
weather 1t is very important that the
batteries in an automobile receive
proper attention, both winter and
summer.
Extra Attention for Batteries
The extra attention required by the
batteries during the summer is not
entirely due to evaporation from heat,
but is accounted for in part by the
fact that the engine starts easier and
therefore less current is used for
starting. Also there is more daylight,
especially in the places where daylight
saving laws have been passed, and the
less. So the battery is more often in
a fully charged condition, and in this
condition the charging current causes
more gas than when the battery is
lever. This condition is due to the
chemical action which decomposes the
water, the hydrogen and oxygen gases
passing off through the vent holes; the
water escapes from this cause as gas
and not as vapor, as it does when there
Is no evaporation.
During the summer city streets are
often sprinkled or washed down, SO
that the motorist has to take precau-
tions against skidding. Most skiddng
is caused by turning corner when GO
ing at too high speed. This often
causes skidding of the front wheels, as
we'll as the rear ones-that is, the car
IS going so fast that the front wheels
do not get traction enough to change
their direction, and when they attempt
to make the turn they skid and the car
goes for the curb. Applying the brakes |
will usually overcome this skid.
In rear wheel skid however, one
of the worst things to be done is to
car coast, turning the front wheels in |
the direction in which the rear end Of /
the car is skidding. If it is trying to
80 to the left, turn the front wheels |
that way. If there is something in the I
way, so that it is necessary to stop, the |
brake may be applied little as the +
wheels take hold, leaving the clutch
engaged, which prevents locking the
wheels, as the engine is pulling against /
the brake and there is not so much I
danger of locking the wheels. 1t keeps
the wheels revolving slowly, so that /
the driver gets better traction for
stopping.
Keep Wheels From Sliding
1t takes greater pressure applied |
laterasly to start the wheel sliding than
to keep it skidding once it is started
and one can bring the car to q stand /
still much quicker if one can keep the t
wheels from sliding. little practice |
VIII teach the driver just how much he |
can apply the brake without CAUSING |
the wheels TO skid.
In the summer heavy showers NAV
cause some country roads to become |
very muddy, which in turn makes skid !
ding very easy. Non-skid chains should /
be carried in the car and put on the /
tires when going over such roads.
Some roads are sprlnkled with tar I
during the summer. After this tar has I
worked it's way into the roads it makes
chem smoother and eliminates a lot of I
lust. However, when this tar has just I
been put on 1t tends to make the road
slippery and therefore, cars travelling
,ver it are susceptible to skidding.
The tar also is apt to be spattered
'ycr various parts of the machine, es-
,ecially under the mud guards, and
Mould be cleaned off after each trip
yer such road before the tar becomes s
ard and extremely difficult to remove. 6
