0iling, Cooling Systems
Providing High Speeds,
for Every Day Use.

Adaptation and perfection of cool
ing and lubricating systems used thus
far only in the finest types Of racing
engines will be one of the urgent re-
quirements of the motor car of the
future, which Walter P. Chrysler,
president of the Chrysler Corporation,
forecasts will be capable of develop
ing 100 horsepower and speeds up to
80 miles on hour, reports the Guar
antee Motor Company.
A large measure of the success OF
the motor car racers who have as
founded the world BY their tremendous
speeds during the past summer, has
been made possible by development Of
cooling and lubricating systems which
permitted motors TO operate efficient
" ut the excessive speeds demanded.
VITAL TO CAR LIFE.
Mr.. Chrysler, in a recent CONVEX
sation, asserted that these results
would undoubtedly be the basis of even
greater and finer development of cool
ing and oiling systems for, engines in
every day use, inasmuch as the life Ct
a motor depended so vitality on the
proper functioning Of these two
units.
In addition to remarkable en-
cheering developments in oiling and
cooling. we are also on the eve Of
vital changes in crankShaft and cam
shaft design and production, which
viii play an important part in the adj
vent of the car of the future" Mr..
Chrysler said.
~New machinery will be developed
for their production and this machin-
cry will be fitted not only with new
grinding equipment, but with test and
inspection gauges which will auto
matically keep these parts abso-
lutely correct to the most infinitesi-
NAL dimensions.
But it will be in valve tappet de
sign that the greatest advances will
occur. Engineers. long ago, felt that
the mushroom tappet tpye was most
efficient, but the properties of existing
designs failed to provide for durabil-
1ty and utmost efficiency. So for
years they have been working to de-
velop new types of materials which
will function with a minimum OF
wear.
going further exhaustive study. En-
gineers are not satisfied with either
cast iron or aluminium pistons. They
tell us that designs are being perfected
which viii permit the use of allows
combining the desirable physical prop
critics of aluminum-light weight and
rapid cooling-with the comparatively
slight expansion Of cast iron. Such a
material is bound to play a most i'm
poytant part In the development of the
motor of the future.
STURDIER GEARS.
But the car of the future will not
only be the result Of further advances
IN motor development. The rest of
the chassis must keep pace with it.
Finer and sturdier Transmission and
differential gears will be needed. with
better and smoother responsiveness
TO operation, so that the power de-
velopment by the new engine may be
transmitted to the rear wheels with
minimum loss.
Frames Will be more sturdy and
more rigid. Spring mountings will
give greater riding comfort and
greater freedom from road shocks.
I'VE already have designed new
types of axles TO care for the greater
twisting strain Of four-wheel brakes.
Still better braking, which viii make
travel at 30 miles per hour even safer
than 30 and 80 miles an hour is to-
day, viii neeessitate corresponding
strengthening Of axles.
Exhaustive study Of wind resist
ance viii result in the development
Of new body lines, which will be
large factor in increased speed and
greater fuel economy.
The new ear, when it arrives,
win be the result Of a new standard
of balance in a motor car. Its greater
power will be the result Of perfect
coordination. And the other units
viii be designed and built in line with
the capabilities of the engine.
Metallurgical tests will give us new
properties in metals; new production
methods viii give us greater accuracy
and precision of manufacture.
