Lethbridge Herald, The (Newspaper) - October 27, 1970, Lethbridge, Alberta -PAGE 13 Car Life And Human Life Both Benefit By STEPHEN NICELY Auto Editor, Kansas City Star It's the same song they sing all the time. "P-' a tune-up. It's dicapor in the rg run. It will pay for itself in gas saved. It will pay for itself 'n perform we. It will pay for itself in a longer last- ing 'engine. Those who sing the song are the ones who do the tunbg up and fell (he spark plugs. It is what everyone expects them to Bay. Is it really true? Disinterested third parties are not easy'to find, but two ex- perts from San Bernardino, Calif., say it is true and they don't sell spark plugs or do tune- ups. They are in the automotive pollution testing business, not for the i- "Jstry but for the fed- eral government. They say it is all true they add a bene- fit of their own: Tune-ups contribute to longer human life through cleaner ex- haust gases. John Lorance and Jim Bux- ton, test engineers for Olson Laboratories, were in the Kan- sas City area several weeks in- stalling more than in testing equipment in an old ga- rage. "The purpose is to see how the exhaust emission control de- vices are operating in the hands of the consumer and how they hold up under maintenance pro- grams the owners actually Lorance says. "This is the first program sponsored by the federal gov- ernment to, see how these de- vices actually perform in the hands of the public." Up to now, they said, the en- gines were tested by the car makers who follow a strict maintenance program. The car meet Sis requirements, but does the public follow the same program? "John Q. Public does not do too well most of the Bux- ton said. "He drives it... puts gas in. He usually doesn't per- form preventive maintenance. "If he keeps lo the prescribed maintenance of the manufac- turer, he will be in range. If he doesn't, he won't be any- where close to the require- ments. The emissions will be higher. Performance will suffer and so will gas mileage." Engine changes to cut air- borne garbage have made tune- up tolerances more critical, the two men said. Owners of the modified cars are more apt to find them hard to start and hard to stop they just keep right on running after the igni- tion switch is shut'off. Other common complaints are loss of power and pinging on regular gas. This doesn't have to be if the car is kept tuned, one of them said. The engines are running hotter with water thermostats up to 200 degrees. They' are burning leaner mixtures of gas- oline and the timing has been retarded to see that more ofjhe gasoline is burned. If the timing of the explosion and carburetor settings are not just so, then glowing hot spots develop .in the combustion chamber and fire the gasoline at the wrong time without-the assistance of the spark plug, whfch accounts for the engine running after the switch is shut off. It can also cause pinging, which is damaging to the en- gine. In the old days, the richer gasoline mixtures served to cool the combustion chambers and render an easier explosion, even if large quantities of icburned hydrocarbons were dumped into the air. The new rigors inside the combustion chamber also serve to shorten the life of a spark plug. As one of the experts pointed out, one spark plug fir- ing intermittently will double the harmful exhaust emissions of a standard V-S engine. Air filters and idle settings on the carburetor also are critical to economy, performance ana clean exhaust, they said. A dirty air cleaner element makes, it more difficult for the engine to inhale and acts to choke the engine all the time it is running rather than only when it is cold. Radical weather changes also affect the life and performance of an engine in other ways, Bux- ton 'said. It can cause moisture to gathr er inside the engine while running. The moisture, combines with the oil to form acid and the acid eats at the metal. That's why. It is better to drive a car 10 miles than two miles, Buxton said, because it gives the engine a chance to burn the moisture out; "You fake a car and don't maintain it, and it might go 100 000 Buxton said. 1 u take care of mine and drive it miles." ___________ PUT SAFETY ON THE ROAD IN'68 WITH UNIROYAL let's face it.
