AUTO ENGINES TO

War Ends.

! within the last few months the
minds OF most Americans. have
dwelt often and hopefully on a pro-
duction that has heen named the
plane engine produced by the United
States government to help IN tho
subiugatlon OF the Hun. Ths mo-
tor car owner OF today may not see
much connection between his fsv-
critic sport and the above mentioned
fact. but strangely enough. the
gine construction that have been
made during the. war are goinR 10

for the airplana would never have
been possible without tho internal
combustion engine, which reached
relative perfection thru the devel-
opmcnt OF the motor car, Now the
airplane cancels It's original deh. by
developing the Internal com bustion
power plant TO still higher degree

uai car owner to justify a brief re-
view of the field.
To begin with. the designer OF the
aircraft engine, has 10 keep s.ways
before him three cssentlals-- ixht,
power. and fuel economy. These he
must achieve. or his design In worth
less.
Reduced Motor Weight.
In the beginning tho airplsne en-
gine designer started with what
was practically motor car power
plant. He has increased the power
OF the engine. reduced It's weight.

creased its iubrication efficiency,
perfected Its carbureting system.
and It's ignition. All these improve
ments are already being copied by
designers OF motor car engines In
30 far as they apply to the surface
type OF vehicle.
The airpiane designer started with
the same materials that his con
mere OF the land had used. the
same metais. the same methods. In
Itensive experimentation. however.
showed him many things about heat
treatment and alloys OF metal that
had never been dreamed OF before.
He learned how to make stee's OF
unimagined toughness and lixht-
ness. which enabled him 10 nrcduce

reason the airpiane engineers con~

That they have suCcrcdsf IN har-

requirements is attested by the fact
that they have produced planes that
can travel at the rate Of ise miles
per hour and having a cruising rN-
