exceptionally light reciprocating
weight. in combination with the
heavy. 51m crankshaft, makes for
the rapid and smooth acceleration
and deceleration particularly notice-
able in the engine.
\‘nhe Mechanism

Valve mechanism is of the roe ker-
lilter typo so sun :ssl'u! in airplane
practise. its features are quictutss,
simplicity. compact..ch less . trc-
qucncy of adjustment and positive
force feed lubrication from crank-
can-3 supply—:1 unique and valuable
departure from common practise.
Valve wear and valve seat pounding
are virtually impossible with this
method._ it is pointed out. The de-
sign permits all valves to he placed
at an angle. reducing considerably
the well are: of the combustion
chambers and giving :1 compact.
quick burning charge of gas.

ficio'ncy and minimum carbon.
Two icaturos were rtrivcn for in
the cooling systom—ct‘ficlvnt cooling
and rapid warming of the engine
when cold to reduce the use of choke
with its resultant harmful dilution
and carbon formation. Particular
attention was devoted to cooling
cylinders six. seven and eight be-
cause of tho diff ulty encountered
in this respect 1 previous eight-
in-iinc types. The water inlet to
the cylinder block was placed at the
lower extreme rear with outlet at
the front. As the roar cylinders re-
ceive the coolrst water. thin count-
eracts the fan's greater cooling of
the trout ones at the expense or
those further back.
Efficiency Striking.

other degigns. The cylinder block
dedgn provides extra. large “to:
specs around the vulva. enabling
thorough cooling of each and its
seat. and eliminating any burning
or pitting. Though the cylinder
block is one casting. its method
makes each cylinder bore separate
from the next. providing: space be-
tween to gin: uniform (ooling. This
cooling spaco extends down three-
