DETONATING no yojj mcii mwm cm 7 TLifOTOR spirit explodes two ways. One kind explodes A.TJ. instantly—detonates. It has the effect of a sledge-hammer blow. It limits the compression because of its tendency to explode prematurely, and thus reduces power and efficiency.. The Prolonged Impulse The other kind of explosion-—the more efficient kind—you get from Union Motor Spirit. It is a prolonged explosion. The impulse is progressive and sustained, not crashing and instantaneous. It thrusts the piston throughout the entire stroke. So Union Motor Spirit permits* increased compression in your motor, and on maximum compression is dependent maximum efficiency and power. More Power on Hills Thus Union Motor Spirit makes your car a better hill climber. You’ll enjoy a smoother running car. You’ll have new speed on the level and more snap in the get-away both results of high compression. And you obtain more miles per , gallon • because of increased efficiency. - DETONATION—What it is ? v Detonation is a powerful explosion, always aci cotnpanied 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 rending, rapid, L frictional wear. It is the most destructive force known to explosive engineers. » ) Ask your dealer for the New Atlantic Union Motor Manual , & 48 page Illustrated Booklet containing invaluable information.
