SPECIAL GAS
NOT NEEDED
WHY'S Knight Engine
Adaptable to High
Compression

One Of the most important develop
ments OF the year in automobile de-
sign has been the steady trend by
many manufacturers of engines 10
n high compression type. Marked
evidence of this trend can be noted
IN the special grades Of gasoline for
high compression motors being
widely distributed all over the coun-
try by the large oil companies.
This trend, however, merely fol-
lows a pace set more than ten years
ago by the Willys-Overland company.
IL was back in 1915 that the WHY'S
knight sleeve valve engine first en-
pioyed high compression and since
that date owners of this car have
been able TO enjoy the advantages Of
increased power, greater vitality, un-
usual hill climbing ability and a
general smoothness and economy OF
operation throughout.
Engineers point u that h pat
ented design Of the Willys-knight
engine readily lends itself TO the re-
quirements Of high compression, the
limitations imposed in other types Of
high compression engines being en-
tirely absent in the knight sleeve
valve power plant.
One Of the best proofs offered 70
justify the claims that the WHY'S
knight engine is naturally adaptable
TO high compression work is the
fact that this engine does not re-
quire n special grade of gasoline TO
obtain the maximum efficiency. 1t
is notable that other manufacturers
nf ksrh COMMUNICATION anntn0a FRFnm-
mend the use of special grades OF
fuel in order TO secure the results
claimed and TO eliminate knocking.
The Wllys-knight engine, II IS SAID,
operates as successfully on the or
binary fuel as il does on the grades
required for high compression en-
gines Of other design.
Numerous tests have barred the fact
that the Willys-knight sleeve valve
combustion chamber wherein the
gases are highly compressed before
firing, is ideally designed TO provide
n rapid, steady burning Of the fuel.
Defamation, so prevalent in other
types Of high compression engines,
therefore is absent in the WHY'S
knight.
With the additional force impart-
ed to the pistons IN the WHY'S
knight engine. the car is assured OF
greater power, faster road speed,
quicker a~cceleration, unusual vital
ity and a smooth performance which
so often is lacking in other types Of
high compression engines, especi-
ally where such engines employ regu-
lar ordinary grades Of gasoline.
IL is the characteristic design OF
the knight sleeve valve combustion
chamber, with the spark plug located
in the exact center of the compressed
fuel charge. which provides the I'M
surpassed high compression perform
ance of this engine. Distinctly diff
ferent from other engine types, the
combustion chamber of the WHY'S
knight engine is ideally designed for
high compression work, noted auto
motive engineers have claimed. The
entire surface Of the head and walls
r. smoothly mHchined with no pro-
jecting edges to form "hot spots.
The location Of the spark plug re-
suits in the spark having the short
est possible distance TO travel. In
all, IL Is the compactness Of the
sleeve valve combustion chamber
that places this engine as the ideal
type for high compression perform
nnce.
