s4 DETROIT, December 9.-Midweek
introduction of the 1884 Ford cars re-
vealed specific changes il the Weight
models from those of the present year.
Chief amcng them is a new carburetion
system. To this is credited an increase
in power, acceleration and maximum
speed.
Top for sustained speed is now given
by the engineers as 81 miles an hour,
compared with a previous &C.. Acceler-
alton tests have shown pickup from
z to rs miles an hour in "a seconds
compared with AZ previously. The
brake horsepower now is 81 at $500
r. p. m. compared with rs in the 1888
engines
COMPRESSION Ratio the Same.
Compression ratio (633 to u is un-
changed, eS is compression pressure
but the toroue is raised from 149 foot
pounds to 155. There is no change in
the aluminium cylinder head, to which
the 1888 power boost was credited. The
system A dual intake manifold util
ICES a dual down-draft carburetor. Due
to the firing order resulting from the
use of the crankshaft with 90-degree
crank throws. the manifold is of the
lover -and-under" type. each branch
feeding two cylinders in each side of
the engine; that is, two center cylinders
en- c1e side and the two end cylinders
on the other
1t is stated that limited number of
GERS will be supplied with self-feed-
ing carburetor used in conjunction with
the present type of Gin9ie manifold.
This installation reduces fuel consump-
tion and will be supplied where SIM
rlicity in the carburetion is desired.
No fuel pump Is required with this car
buretor. For the dual carburetion sys-
tenn i new fuel pump of the lever-arm
type, similar to that used On the four
cylinder model B" engines is used.
Among the power plant changes is
listed the first production use of
cast alloy steel crankshaft as distinct
from the forged types which have
Been standard in all cars previously.
The metal is high carbon steel alloyed
with copper, chromium and silicon.
Under test it is said to have resisted
breakdown up to twice as many revo-
htions as the forged shafts. end is that
much more resistant to high bearing
presSureS in the new job. Graphite,
it is stated. also is component of the
metal to lessen friction through self
fabrication.
ThermoStats now are provided in the
water lines to reduce engine warming
up and to keep operating temperature
uniform. To add oil economy, new
piston rings are used with modifica-
tions in the pistons, and battle plates
over the oil return holes in the valve
chamber have been put in. Under
ordinary driving conditions, it is said
that no oil need be added between
1,000-mile periods of change.
Valve Assembly Improved.
Unit valve assembly has been adopted
TO reduce time of valve removal or
replacement. Each valve. valve spring
retainer and the split valve guide are
assembled in single unit. 1t is esti-
mated that from one to two hours
scrvice time is thereby saved
Chassis and body changes that have
heen made are in the way of refine
nnent of previous construction. The
wheelbase stays at 112 inches, with the
windshield slant remaining at the 90
degree angle. The cars get new
tPpSol oA4SC ALOll
With deeper radiator shell and elimina-
t:on of the curve in the grille. The
Victoria body type is an addition to
the line and it has a luggage COM
partment built in at the rear.
The only frame change is a rein
fcrcement of the front cross member
to stiffen the front end. The ratio
OF the steering gear has been changed
to Is to l from 13 to /.
Coincident with an assembly of
dealers here. the Hudson Motor Car
Co. has revealed its optional inde-
pendent wheel suspension plan for
wheels.
Called "Knce Action"
So-called knee action" is obtained
from an articulated front axle on a pa--
allelogram plan, which permits one sd,

pinned at both ends and mounted one
above the other. The links lave roller
bearing forks at their extremities,
through which the pins pass, allowing
vertical action and maintaining align
ment.
Change thereby is confined to the
front axle with no alteration in steer
ing or suspension.
