Advantages of Sixteen Cylinders Sixteen cylinders have been chosen for the world's most luxurious motor car because of the many advantages inherent in such a design. Smoothness: This engine is the smoothest in automotive use in the world today because its sixteen small cylinders give explosive impulses every 45 degrees of crankshaft revolution and generate an almost continuous flow of power. This is V-type design as near perfection as only Cadillac could build. A graphic comparison of the low speed torque impulses (engine fluctuationdue to power generated with each engine revolution) of the Cadillac Sixteen with (Above) Sixteen Torque Curve (Below) Typical 12 Torque Curve those of a typical twelve cylinder engine of approximately the same size shows a harmonious flowing curve for the Sixteen and an irregular, impulsive curve • 206»
for the twelve. Furthermore, as the speed increases, the Sixteen fluctuations become smaller while the V-12 fluctuations increase. The twelve cylinder vibration curve variations reach a maximum when coasting at high speed, whereas the Sixteen torque variations become zero, represented by a straight line, under these conditions. Durability: Because the displacement of each cylinder of a sixteen cylinder engine may be smaller, the very short stroke of 3¾ inches is possible. This engine has the lowest piston travel of any American made automobile. This is in conformance with Cadillac practice of a large engine of tremendous reserve power yet always operating slowly, thereby achieving longer engine life and operating economy. Piston^ travel of the new Sixteen engine is 1590 feet per mile: of a typical twelve, 2270; of LaSalle V-8 and. Cadillac Sixty, 2080. The short stroke reduces the inertia forces of Jthe reciprocating pistons. Connecting rod bearing loads are thus reduced, thereby increasing durability. The short stroke contributes still further to connecting rod bearing life because shorter and lighter rods may be used. With the short stroke and light impulses two inch diameter crankpins afford extreme rigidity and reduce rod bearing friction. Small bore engines wear less than large bore engines having the same piston travel. The use of sixteen cylinders makes it possible to use a relatively small piston despite the very short stroke. Performance: Sixteen cylinders permit large displacement for a given hood length. Furthermore, the small cylinders permit the use of the high 6.8 to 1 compression ratio which increases combustion efficiency, resulting in greater power development relative to engine REVISED 12-15-37 • 207»
