You are asked perhaps to buy a car already equipped with an Air Cleaner; or importuned to put one or the other of a dozen different kinds on your present car. How are you to choose the best cleaner, and avoid being disappointed? This booklet tells you how. Read it carefully. It is a simple, easily understood explanation of what Air Cleaners are; how they work; and what they do for the money you invest in them. As you are probably aware, these Air Cleaners are devices applied to the air intake of automobile carburetors, to remove the gritty dirt and fine dust from the air, before it enters the engine and causes trouble and expense. The advantages claimed for all Air Cleaners is that they minimize the wear and tear of all moving parts of the motor; reduce carbon deposit, with its attendant valve grinding and scraping expense, and greatly increase the life of the lubricating oil. All of these desirable advantages it is possible to have in varying degree depending upon the over-all efficiency of the particular cleaner used. By over-all efficiency we mean something more than mere ability to remove the dust from the air. We mean a lack of resistance to the air flow into the carburetor for one thing. This is something that is rarely mentioned in Air Cleaning advertisements, as—with one exception only—they all restrict the flow of air. The practical effect of this restriction is to materially reduce the horse power output of the engine, reducing its speed and incidentally the speed of the car, and greatly increase the dilution of the lubricating oil with unburned gasoline. This restrictive action is partially compensated for by screwing down the needle valve of the carburetor, or changing to smaller nozzles—a recourse equivalent to using a smaller carburetor on the car. | ||
