Smith's Interest in the three-point spension idea in engine design en- | couraged him to keep his ears open for other interesting topics more or less strange to the average motorist. Being in a receptive frame of mind, therefore, he was quick to sit up and take notice W he overheard two car owners dl sing the possibility of the retirn of the two- ne, provided certain obstacles overcome. Smith no time in seeing his fa- te repairman. " he s of en overheard some Iiut before I ask you to enlighten me 1'd like to know what sort of engine I've got in my own car. I know it's a valve-in-the-head six and all that. But there's evidently some feature about it I've overlooked.” Joe stopped work to light a clga- rette and invite Smith to make him- f at home, running boards serving as morris chairs. For a moment Joe appeared nonplussed how to explain so0 simple a difference between the two sic types of gasoline engines. yours Is a four-cycle engine,” he began. ‘“Most Internal combustion en- gines today are of this type, but the only way I can explain why it's the popular type is by telling you how a two-cycle engine works.” Explaining the Engine. “Let 'er go,” Smith agreed. “I'll nterrupt you when you get too tech- m not going to be technical,” Joe d. *“If you drive a car you know— or you ought to know—the general idea of a cylinder and what happens in it. Ina cylinder you have a hollow piston which travels up and down, re- volving a shaft beneath it by being joined to 4ts crank with a connecting rod. Explosion of compressed gas va- por by an electric spark drives the piston down; momentum of the fly- wheel carries it up again. That’s th idea of it in a nutshell. “The next thing is to provide some means of admitting gas vapor to the linder and releasing the burned gas. r this we use valves. The two- cycle engine being an early develop- ment, the first valves that occurred to engineers were holes or ports in the cylinder wall which would be uncov- ered when the piston was down. One of these ports connected with the car- buretor, the other with the exhaust. Dut there was also a tube from the intake port to the air-tight base of the_motor. “The next point is to see the thing in operation. We crank the engine and make the piston rise to the top of its cylinder. The suction created in the engine base draws gas vapor into the base from the carburetor. The piston, having compressed some gas at the top, travels down on Its power troke when the gas is fired. In go- ing down it forces out the gas in the base. This comes around through the intake port to the top of the cylinder, now that the piston is down. At the same time the burned gas goes out the exhaust port, the two gases be- |ing somewhat separated by a baffle plate attached to the piston. Thus every other stroke of the piston is a So we call this type ‘two-cycle.’ Four-Cycle Operation. “In the four-cycle engine the base of the cylinder plays no part in the job. Ports are replaced by mechani- cally operated valves, one furnishing an opening for the exhaust, the other for the intake. These are operated by the camshaft, opening and closing at the exact time. When the piston comes up the exhaust valve opens and the cylinder is completely cleaned out. When the piston travels down the ex- haust valve closes, the intake opens and the piston sucks In fresh gas va- por. When it comes up the second time both valves stay closed, the gas |is compressed, fired and the piston goes down on its power stroke. There are four distinct strokes or cycles.” “Well, that seems more sensible in every way,” Smith commented. “The piston does work only on every fourth stroke, but the arrangement {s so much more accurate that the engine should be much more efficient than a two-cycle. T should think the gases would be mixed in the two-cycle en- gine, so that the cylinder would never be clean. With the sort of gas we use today the engine would be skip- ping half the time.” “Now you know why there isn't much chance for a return of the two- cycle engine in automobiles,” Joe con- cluded, returning to his work. ‘“To be efficient it would have to be com- pletely revised. But what really killed it was the advent of the multi- cylinder engine. They found that one- cylinder engines offered too much vibration, so more cylinders were added. And with more cylinders the advantages of having each cylinder deliver an impulse for each revolution of the crankshaft were unnecessary.

Think of the years of painstaking but prideful devotion to a standard —the carefullytrained habits of years— the ineradicablz and unpurchas- able traits of arusanship that can come only with the years! Imagine the futili of trying to find such men, in the full bloom of their craftsmanship. Think of the years it would take to bring them to thelevel of Cadillac of today,—with Cadillac all during these years ever perfecting its equipment, its methods and the orderly its men. Obviously and inevitably in five years, or, in 20, Cadill-~ lead- ershi is right this minute. $2,500,000 will build and equip a prepared to produce a profitabfe automobiles—but not Cadillac 90 inder automobiles. Here are the Mechanical and Performance Reasons for Cadillac Leadership In the short Cadillac engine the fuel mixture to the various cylinders is more uniform. On the V-Type Cadillac the maximum distance between carburetor and any cylinder is only about '3 the corresponding distance of an all-in-line engine. The V-Type Cadillac is more efficiently cooled, because of the more uniform temperature of water around the various cylinders. V-Type Eight cylinder blocks is wider, and cessible for valve or carburetor adjustments. Last, but by no means least, is ation of vibration. A simplemathematicaldemonstration provesthatthe Q0degree such as Cadillac builds assures regular firing intervals — which is not possible with 60 degree V-Type Eights. This results in a more uniform torque, an even application of power, and greater smoothness particularly at low speeds. In the Cadillac 90 degree V-Type Eight the “Vee” between the 90 degree V-Type Eight can utilize the natural compen- sating principle which is the root and source of the elimin- The V-Type Eight is shorter and more compact than anyall- in-line engine of the same number of cylinders. More than that, it is shorter than any other engine with the same piston consequently much more ac- the inescapable fact that only requires fewer 7 to 9 bearings are The crankshaft of a V-Type Eight being short, 18 much less subject to twist, thus eliminating torsional vibration. That is why a vibration dampener is unnecessary on a V-Type Eight.
