NEW CADILLAC IS
 EIGHT-CYLINDER


 l powered with an eight cylinder engine l of the V-type, the Cadillac Motor Car l company becomes the first American manufacturer to develop an eight-cylin- | der car for the market, and the only manufacturer whose latest product em- bodies a vital advance in engineering and in motoring.
 l Thus are set at rest the rumors which | for weeks have presumed to forecast Cadillac intentions and plans. | In the light of past developments it | seems only logical that the Cadillac should be first in the American field with an eight-cylinder car, as a glance
 at motor history will show. l The first high grade at a popular 1 price was the original Cadillac Thirty
 and this car opened up new field to 1 the industry.
 l For a year the Cadillac was the only 1 car to carry an electric starting and l lighting system-a feature that has be- 1 come an important part of the regular l equipment of almost every car. As the Cadillac statement announcing | the new car puts 1t:
 This company has never relaxed Its l pursuit of that power principle which
 would prove to be ultimate and final. l We sought the medium by which the Cadillac would be endowed, not with ap- l proXimate freedom from gear shifting,
 or approximate hill-clinbing ability on | high or approximately swift accelera-
 tion but with the highest possible form
 of these three characteristics l "The Cadillac company has given seri- ous consideration to every reputable | type of motor-endeavoring to scruti- nize with scientific impartlalty the vir- l tues and the limita tions of each and every one alike.
 Building and experimenting in turn, | fxrna frap ha cf. aolo lin
 der to the six. and from the poppet to i the rotary and to the sliding valve, we
 have been carried forward to the high
 est form of frequent impulse motor-the Vtype eight-cylinder.
 l The principal advantage of the eight 1 cylinder engine is. of course, its continu- I ous torque and continuous uniform gen eration of power. There is no pause or
 lapse between power impulses, of which
 there are eight in each complete cycle | of the engine, four to every revolution of the crankshaft or one every quarter turn. The firing alternates from side
 to side. The continuous torque produces an almost utter absence of vibration, at l both high and low speeds w. G. Aston. writing of the V-type of eight-cylinder motor in the Autocar 1 Imperial Year Book, London, classifes its advantages under four heads, viz size, weight, torque and cooling. Under the head of size he comments | on the shortness of the construction. which not only reduces periodic vibra- tions in the crankshaft, but affords more space for body work on chassis of standard length. No extraordinary
 length of inlet piping is required, as the
 N-form cylinders lend themselves very
 readily to a piping arrangement that enables every cylinder to receive a prac- tically uniform charge of gas. In the matter of weight, the short ness of the V-type eight again figures. Mir Aston pointing out the reduction in the length of crank case, the lighter crankshaft and flywheel, short camshaft and lighter reciprocatlng parts because of the comparatively smaller size of the cylinder on given power basis As to torque. he shows by illustration that the torque of the eight is more
 uniform and that additional cylinders could do no more than increase the power.
 The author points out that in the cooling system, each block of cylinders is treated as a unit. and the water cir
 culation has no tendency to form pock-
 cts around the valves.
 The cylinder dimensions of the new Cadillac engine are comparatively small -3b inches bore and 5& inches stroke yet in repeated tests by dynamometer
 an excess of 60 horsepower has been reg | istered.
 The cylinders are cast In two blocks of four cylinders each, with water jack cts. combustion chambers and intake
 manifold integral. The cylinder blocks are mounted on the crank case at an
 angle of 90 degrees to each other, from whence the designation, "v-type" The cylinders are of the I. head type.
 with all valves on the same side of the cylinder blocks.
