AUTO MELTING
POT" PRODUCT
Composite 1913 Car Shows
Many Changes From Pro
duct of Last Year.

The composite 1913 automobile is an
I interesting creation of the statistician.
! showing the general trend of motor car
/ development As designed by the No
l tor Age expert the car from the melt
( ing pot would have these specifica-
lions.

The composite car is the average Of
all the cars on the market for 1913
and embOdies the features Of all these
cars and with its longer stroke and
shorter bore, it is in good contrast TO
the 1872 average product. Not only as
regards the bore and stroke does che
average or composite American car
differ from the sitting of the 1912 out
put but in many other respects.
The bore of the average 1913 car is
4-19 inches, a considerable decrease
from the 1912 figure-4.34 inches. The
stroke, on the other hand. has in
creased from 497 inches in 1912 to SIS
inches in 1913.
Power Is Increased.
That the S. a. E horsepower rating
remains the same 1916, does not indi-
cate that the motor is of the same ac-
tual power, for the piston displacement
has been increased considerably this
year The 1912 figure showed that the
average piston displacement was 1862
cubic inches as against $3.50 cubic in
ches this year This long stroke motor
developing more actual power than the
average motor OF 1912 is much more
flexible and quieter than its prede-
cessOr-
The resultant Of all the 1918 cars
has fOur-cylinder motor, with cylfn-
ders of the L-head type cast in pairs
~ The water circulation is by a pump and
through a cellular radiator. The ten
dency toward the pump circulation OF /
water has not increased very much |
over 1872, the percentage Of cars using
TINS method a year ago being IS. and I
this year an Increase Of 8 percent is
noted, bringing the figure up TO 20 /
percent
Tubular radiators have decreased In /
number since 1912, a considerable ad- |
vance by the cellular tyne being noted |
Besides having these various charac-
teristics, the 1913 composite car has a /
splash system Of motor fabrication. /
Dual ignition is another desirable fea- /
Jure Of TINS motor, this system having /
made an increase of five percent over
the 1912 percentage.
Dual Ignition.
A year ago IS percent Of the cars on
the American market were equipped |
with dual ignition. and this year sees
this rise to IS percent.
The motor is fed by gravity. The !
running gear Of the average car on the
market this year embraces a disc I
clutch, threespeed selective gearset To-
Gated amidships- The drive is through
a shaft to bevel gears to a floating rear
axle
The gear ratio is S.57 to 1, slight
decrease in respect to the 1912 ratio.
which was 1852 to 1. Due to the greater !
percentage Of skies on the market this l
year the average weight has increased
to 1850, as against 229O in 1912 This .
increase in weight is, Of course, accom-
panied by an increase in tire size.
In 1912 the average car had S5x4 tires 1
and 1913 sees 35x4 - as the average
ire size. Starting the motor BY cleo
richly seems to be in favor since 81
percent Of the cars on the 1913 mar
let are so equipped.
