How Uni Stops What is Detonation? What is Detonation? Detonation is a powerful explosion, always accompanied by a sharp, quick report. It tears, jerks, pounds and knocks, if not properly controlled. Whether in a cannon or in an automobile engine, detonation causes a rendering, rapid frictional wear. It is the most destructive force known to explosive engineers. UNION ETHYL ETHYL GASOLINE Kenneth V. Laker ANAHEIM GAZETTE Union-ETHYL rops Motor "Kn Perhaps you have been puzzled by annoying knocks in your car. That jerky uneven pull on hills, in traffic, gears, has made you wonder how this knocking comes a The answer is detonation. Let us illustrate with an example of smokeless powe guns of the army and the navy. Without smokeless powder modern big guns would not be practical, for after only a few shots with a charge such as dynamite they would be unfit for further use. The damage would result from detonation—all the force of the explosion being expended in one crashing blow against the projectile. Dynamite would be a detonating charge. In combination with Union line it represents the smoothest of fuels now known for It stops the “knocks” by c tion—by causing the gas to expanding power throughout piston’s stroke. Heavy “knocking” in a m Without smokeless powder modern big guns would not be practical, for after only a few shots with a charge such as dynamite they would be unfit for further use. The damage would result from detonation—all the force of the explosion being expended in one crashing blow against the projectile. Dynamite would be a detonating charge. But "smokeless" powder is non-detonating. Its explosion (burning) and the power from it are sustained against the projectile throughout its entire movement through the gun. A tremendous force is thus unloosed under good control. Here is greater power with less recoil. And projectiles are thrown several times as far with less harm to the guns. Union Gasoline has always been an outstanding non-detonating fuel for motor cars, acting against a motor's piston as smokeless powder acts against the projectile in a gun. It exerts greater power with less "knock" and vibration than ordinary detonating gasoline. And now comes the Ethyl compound, a highly effective agent that science has developed after years of tests and actual use to still further control detonation in a motor fuel. In combination with Union line it represents the smoothest erful of fuels now known for It stops the "knocks" by cation—by causing the gas to expanding power throughout piston's stroke. Heavy "knocking" in a more detonation of a high explosive range gun. Union-Ethyl's action is likely powder in the modern long-range dreadnaughts of the world. It completely ends the "knock." Thus lack of power, sluggish pick-ups, and the kindred knocking cause, are entirely due to strains on your motor and come less frequently. A driving soon becomes your problem. Try Union-Ethyl today.
