This *caf has only one life. It’s the ... Catalytic conwrter in '75 models designed to fight air pollution

There’s one “cat” that doesn’t have nine lives. That’s a catalytic converter on 1975 model cars. Prolonged use of leaded f ael will kill the effectiveness of the pollution-fight-ing unit. The converter s job is to change carbon monoxide iCO» and hydrocarbon (HO emissions into harmless carbon dioxide and water Catalysts of ceramic beads and inert metallic pellets are used in the process. Leaded fuel coats the pellet with lead deposits and renders them ineffec-

tive. As a result harmful emissions escape the muf-fler-like unit and enter the atmosphere. While the car would perform normally, pollution levels would exceed legislated levels. Designed to function for a minimum of 50,000 miles, the converters also are expected to help improve gasoline mileage. Unleaded gasoline is now available at most gas stations in the U£. The gas is expected to be carried by outlets in Canada and Mexico, particularly in areas where UJS cars fre-

quently travel. Should you be out of gas in an area where lead-free fuel is not available, then buy enough gas to get you to a station where the proper fuel is sold. A converter can tolerate an occasional usage of leaded fuel, since the heat of the oxidation w’ill burn off lead deposits once unleaded fuel is reinstalled. The catalyst will then return to full efficiency. TO prevent inadvertent filling with leaded fuel, a smaller gas filler neck is found on 1975 cars.

gig ► o * - c? s I'hc job of the catalytic converter is Io change the “dragon's breath” of H(. and CO pollutants into emissions of harmless carbon dioxide and waler vapor. In order Io achieve this environment plus, converters must avoid leaded gasoline. 197 S cars equipped with catalytic converters are designed to run on unleaded fuel and gasoline filler apertures only can accommodate nozzles from pumps issuing lead-free gasoline.

These rules may help you get out of sinking automobile

If you are ever unlucky enough to be in a car that enters deep water, the Canada Safety Council offers some advice. ATcar floats for a short tirhe after hitting the water in a near horizontal position irrespective of how it hit the water. The time varies with make from a few seconds to three or four minutes, after which it sinks vertically, engine end first. Rules for escape are: 1. Immediately after hitting the waler, release your safety bell. 2. Open door windows, movable roof (if any), and/or bark window. Leave the car via the bol route as quickly as possible. During the floating period, it will be difficult to open the doors because

Gasoline safety saves valuable fuel, lives

Here’s away to save gasoline, and possibly your life, too. Gasoline vapor is a deadly killer, but few people recognize its danger when they use it for cleaning purposes. “Never use gasoline as a cleaning fluid,” advises the American Petroleum Institute’s Safety and Fire Protection Committee. “Use only an approved, high flash point cleaning solvent." Gasoline vaporizes rapidly when exposed and the vapor settles invisibly near

of water pressure from the outside. 3. If it is impossible to leave the car while floating. the car doors can usually be opened underwater because outside pressure of water has been equalized. 4. If the car is damaged Io the extent that none of these ways of escape can be taken, use the feet or shoulders to remove the front or back window by pushing it out. This can best be done by pushing in the corners. When a car sinks in water, outside and inside lights should be switched on if possible. This lessens confusion in the vehicle, and makes location from above easier.

the floor because the fumes are heavier than air. Gasoline vapors have been known to travel many feet to an ignition source resulting in a "flash back” to the liquid. An explosion can be caused by the slightest source of ignition, such as a pilot light, an arc from an electric motor or power tool, the flick of a wall switch, or a lighted match. Remember, it takes three elements for combustion — air, fuel, and an ignition source. Keep them apart Don’t Use Gasoline As A Cleaner!
