Under Way Since 1915.
From a design standpoint. Series
10 Franklin introduces some entire
" new ideas in air-cooling which
are the embodiment OF work start
ed By Franklin engineers as far
back as 1915. The cooling appara-
tus functioning on the new motor,
and called the pressure system. Is
known 10 have undergone tests on
over a score 20 cars. and aggregat-
ing 100000 r1ilas. before It's adop-
ton. II develops a current OF cool
ing air which IS fully two and one
half times that Of the former Frank
lir system.
The new cooling system takes the
air IN az the front OF the motor and
forces II over the cylinders. This Is
the direct opposite from the method
formerly employed in which the air
was drawn IN by a fan set IN the
ay-wheeI AZ the rear OF the motor.
A blouser or fan az the forward end
OF the crankshaft and encased in
an aluminium housing. The air
forced In by the blower passes
Though a continuation OF this alu-
nainuTn housing, Is carried over the
upper ends OF the cylinder jackets
and down across the cooling fms
which are set in the walls OF the
cylinders.
Cooling Fms Changed
A change has been made IN the
cooling fms. the ends being bent at
approximate right angles go that
they form what practically amounts
10 a close jacket about thu cyInd-
crs through which the afr is con-
Quoted. This does away with the
use OF the separate outer jacket as
used in former models, Affords
greater cooling area and permits
reduction IN the length OF the rms
themselves
with the new pressure system OF
cooling. the air forced in by the
blower ~ absolutely controlled by
battle plates placed in the aluminium
uaseageway already referred TO, and
this makes II possible to direct the
necessary amount OF air TO those
points where the greatest amount
OF heat r. developed.
Fuel Transformer Uses Low Grade
Gas.
To mako possible the most en-
cieut use OF the steadily lowering
quality OF gasoline now ofrered the
motoring public. the new Franklin
motor is equipped with what Frank
lire engineers term a fuel tranSfor-
mer This device r. IN the shape OF
a cylindrical aluminium casting with
corrugated walls surrounded by
heater Jacket through which the
exhaust gas OF the engine Is passed.
Raw gasoline on its way TO the in

which the use OF Durelamin for
connecting rods f. an innovation.
