,.V Uliys-Ku!ght. the knight motored
cA- which has been more or less
,broudcd in mystery, is to be offered
10 the public for sl,O95. the lowest price
make. The essential difference Of the
KNIGHT type motor from a poppet valve
motor is IN the valve arrangement. The
Knight has a sleeve valve motor, the
valves being merely sliding sleeves.
There are two. one inside the other slid
l7e I'd and down between the cylinder
wall and piston. IN each openings are
placed which at the proper time in the
action Of the motor come opposite to
each other so as to permit the charge
Of fresh gas from the carbureter to enter
the combustion chamber and similarly
from the burnt gases to pass from the
cylinder out into the mufsier.
lnasmuch as the power OF any motto.
% largely determined by having the
fresh gas in sufficient quantity enter
the cylinders at exactly the right mo-
mfHN ahu ApOi ~ NOllplCt0 EXPULSION
Of all burnt gases, also at exactly the
right moment the poppet valve imposes
certain limitations upon all poppet valve
motors.
The large sleeve valves of the knight
type motor permit valve openings much
larger than can be had with poppet
valves. The sleeves have a positive
action, as they are opened n closed
By positively operated connecting rods.
and therefore there is no uncertainty
sither as 10 the time or extent OF the
opening. There will always be a full
opening, regardless OF the speed OF the
motor.
There has been a more or less gem
1ral idea among those only partly IA
niliar with the knight construction that
the operation of the sleeve valves might
oner some difficulty. This is because
it has not been known that the sleeves
10 not have to be made to a tight At
to hold compression as is true of the
piston. The sleeves In operation are
-"usN WIN u ulfn OL OIL. Even
more i,upornrt to the successful oper-
alton Of the Knight type motor than the
TACT that the sleeves are not called
upon to retain compression is the rela-
lively slow movement Of these sleeves.
Whereas in the Willys-Knight motor the
piston has a stroke of 4La inches, the
sleeve value travels but one inch at
one-Aa.f the motor speed. In other
words. the sleeve valves travel at only
one-ninth Of h piston speed. This
means that If the motor is travelling At
The rate OF 800 revolutions a minute.
and which would be equivalent to a car
speed OF 2i.6 miles An hour. the sleeve
waves are only travelling at "A ate
at which the pistons would travel at "a
speed of 100 revolutions a minute.
The low price is mad possible only
oy the great manufacturing facilities OF
the Overland plant and the fact that
the car will be produced la larger guam
titles than amy Knight type motored cor
was ever before produced. Heretofore
might type motored cars have been
lJeked upon az belonging TO a de luxe"
tad all their own. Their sale has been

Ieople who could afford to pay a high
plice for the advantages and comforts
which this motor affords.
