DETROIT, August 20.-The Ameri-
can automotive engineers are going to
have more than spectators interest in
the Harmsworth Trophy races on Lake
st. Clair. near here. September 2 to 5.
The designers of the challenger's en-
gines, If advance information is correct,
have accomplished something the Amer
lean automobile engine designer has
been developing more slowly for many
years-stepping up horsepower while at
the same time reducing the weight OF
the motor
Tie automobile engineers, Of course,
will want to see Gar Wood in his Miss
America X successfully defend the
British international trophy against the
challenge of Kaye Don in Miss England
III, but they will be more interested in
a peep under the hood of the British
boat. The chances. however are very
much against their being granted this
privilege.
British Keep Secret.
The designers of the British crafts
engines are said to have turned out
pair Of motors weighing about Is ounces
to each horsepower. How they have
done this Is secret of the British air
ministry and it is extremely unlikely 1t
will be disclosed to any one during the
few DAYS Miss England III will be in
American waters Immediately after the
race. the craft undoubtedly will be ship
ped back to Montreal. en- route home.
lighter engine developing greater
horsepower long has been one OF the
chief detectives of American engineers
They have done much in this direction
IN the last decade, but are still dlsast-
fed.
DEVELOPMENTS during the last few
years in perfecting light weight Diesel
fvne engine are of particular signifl-
canoe. There is, naturally. sharp dill
ference of opinion among automoblle
engineers regarding the comparative
qualities of a gasoline internal COM
bustion engine, such as the motorlst mas
become accustomed to, and Dlesel
type motor burning the crudest OF 1ur-
mace oil.
Made DieseI-Powered Plane.
Yet many automotive engineers con-
cede that the late Capt l.. M. w. WOOL
son accomplished what long had peen
regarded as impossible when he de-
siened and built a Diesel type airplane
motor. Previously the Diesel engine
was considered adaptable only to sta
tionarv work. because of the great size
required to withstand the strain on It's
various parts caused by its principle OF
operation. The Diesel engine has no
electric ignition. depending upon neat
generated by compression to explode the
fuel oil.
Some time after Capt Woolson pat
ented his Diesel type airplane motor
a single automobile powered with an
engine constructed along similar prln-
ciples was brought out and expert
ments conducted. So far. however, 1t
has not been introduced commercially
1t has been said that engineers IN
their present laboratory work are look
ing from to 10 years ahead. Thls
probably is correct as 1t applies to some
phases of their work, but few are pre-
nared definitely to say whether Diesel
tyne motor will or will not be brought
nut In the near future that can be made
commercially successful in an automo-
bile
Moreover, under the stress Of compe,
tition the engineers are withholding
few. If any, developments perfected II
their research work. The various pro
ducers in the industry have the ad
vantage of the licensing plan o
the National Automobile Chamber o
Commerce. making numerous invention
available to all, but so keen has com
petition in the trade become that thu
engineers literally are giving the buylnl
public every possible Involvement tt
