Clean "Where there's smoke, there's fire," goes the old saying. The same formula doesn't necessarily- • apply to air pollu- tion. Jiust because there's no visible sign or --pollution coining from your car's exhaust pipe, it may not mean your car isn't polluting excessively. Visible exhaust smoke generally appears when the engine is malfunctioning. Burning oil in the engine or an excess of unburned gasoline helps create the exhaust 'smoke. These are obvious signs that your car is polluting. However, there are times when an oversupply of unburned hydrocarbons, carben man- - , . __.,,....-_ - oxide and nitrogen oxides following should be checked cannot be seen. If this is the at your favorite service out - 'case, how can you tell when. ;, let: -your car. i$ .polluting?. Look for these warning signs: ENGINE TUNE-UP: A complete- tune-up every year ,,.pry .A.

A five per- cent rate of misfire can in- crease unburned hydrocar- bon emissions, by 300 percent. Consider a clogged PCV valve or dirty air cleaner. These can almost double the pollutants from your engine. In addition, a University of Michigan engineering school study showed that emissions of unburned hydrocarbons 'were reduced an average of 55 percent following tune- ups. To make -certain your car is as pollution -free as it was originally designed to be, the tion, an"engine check "should be , performed every 5,000 miles. Tune-up should in- clude new spark plugs, points and condenser plus other basic services your engine needs. * * * COMPRESSION TEST: a Check for worn piston rings and burned valves which al; low eaicessive smog -produc- ing pollutants to escape from your engine. * * * EMISSION CONTROL DE- VICES: To be effective, these components must be serviced ,regularly as directed by your ear owner's manual. -• ' * * * Cars of today are 60, .per- cent more pollution free than those, of 1964 and in a few years the internal com- bustion engine will be virtu- ally non-polluting: •But con-' scientious maintenance will still be needed to keep them that way. Autos Dept In Tune Hum .Clean " Air Song It used to be when a mo- t—ppu-lled_.-into a -service outlet and' told an employee to "Check the air," it was a natural assumption to: look at tire pressure. Today, checking the air has an additional meaning. It means checking the engine to make sure- the car is not adding unduly to the na- tion's air pollution ,problem. EEven though the nation's auto manufacturers have taken significant strides in reducing air pollution from automobile engines, the fail- ure of the car owner to keep his ' ngine in shape has hel ed, slow progress. l or example, studies by 'Champion Spark Plug" Com- pany show that a five per- cent incidence of spark plug misfiring, caused by engine neglect, can increase the emission of pollutants by 300 percent. And studies by a group at the :University of Michigan engineering school show that harmful emissions can be reduced by an aver- age of 55 percent after a tune-up. - HOW TUNE-UP CONTROLS POLLUTION Causes' of pollutants are the wastes from gasoline that are incompletely buried. :These wastes are minimized in a tuned engine. When an engine is out of tune, there may not "be corn - Pete combustion of the gas- oline/air mixture and a greater production of con- taminants is the result. -- Therefore, an engine check every 5,000 miles and a com- plete tune-up every 10,000 miles is recommended. In addition to elements of a tune-up, there are _other key items to help cut down on pollution: the PCV valve, the oil filter, the air filtel; and the gas filter. * * * PCV means "positive crankcase ventilation," but we can call -it "pollution con- trol valve" for easier under- standing. •The system has a valve which regulates the flow of noxious fumes into the carburetor so that en- gines will continue to run while reducing pollution. PCV valves should be changed every -12,000"" miles or .every tune-up. If a valve becomes plugged or worn it is useless. •-- _...... . OIL FILTER: Smoke - belching `engines are worn out. They wear out when grit, acids and other junk in the oil enlarge the cylinder Walls permitting the ehgine to burn the oil. The best way 'to prevent this . polluting wear is to change oil and oil filter at least every 4,000 miles. FILTER: With every gallon of gasoline a oar burns, it also .inhales 10,000 gallons, of air. If the air is dusty, the grit wears out the cylinder walls, permitting oil to be burned, which pollutes. Also, as the filter traps dust, the amount of air entering the engine is reduced ... en- riching the fuel -air mixture, which pollutes. So Change the air filter every tune -w. GAS FILTER: Grit in gas- oline can plug carburetors and cause 'stalling. So it's also important_ _to_ change gasoline fili;e1. t Pollution Among the 40,000 auto service technicians, who will attend Cleaner Air Clinics this year is this -group in ,Laurens, South Carolina. Champion Spark Plug Company technical services engi- neer Sam Rollins is one of 14 men the firm sends throughout the United Statet to' give service personnel the latest techniques in com- . batting pollution. CharnpionVanTaking `Clem Air' Clinics to Nation's.... Servicemen • There's a red, white and black van' coming to town that looks something like a delivery truck. The cargo is cleaner air for .t e.. commu- nity. The truck, in actuality, is a Champion Spark Plug Com- pany mobile training van used in conducting Cleaner Air Clinics for area automo- bile •service personnel. During the coming year close to ,1,000 of these clinics will be conducted through - 'out tile United States. More than 40,000 service techni- cians ,are 'expected to learn how tune-up or lack of same affects air pollution. — Champion maintains a team of 14 regional technical' services engineers who trav- el the country in their spe- cially -equipped vans. In addition to providing technicians with basic tune- up precedu-res, the clinics demonstrate how tune-ups help reduce unburned hydro- carbons. and darbbi .°monox- ide emissions. Special empha- sis is made on the effects of worn spark plugs, engine ad- justments and the need for regularly scheduled mainte- nance in combatting -pollu- tion. SMOKE SCREEN If you're lboking for an- other reason to quit smoking, consider your driving safe- ty. Tobacco smoke leaves a dulling film on the inside of your windshield. The result is reduced visibility and stronger glare. If you do smoke, periodically clean the inside of the windshield with a. solution of water and vine- gar to wash away tobacco film. Drive with care, and get there! A. Y The .Champion engineers work from a specially -equip- ped mobile training van that allows them to demonstrate most conditions causing trou- ble in automotive ignition systems. Heart of the unitis multifuell, single cylinder engine equipped with a dy- namometer. This unit can simulate almost any high- way driving situation. The van also houses spe- cial instrumentation includ- ing measuring devices for ex- ,haust emissions. According to George M. Galster, director of Cham- pion's automotive technical services; "The clinics_ enable us to shpw 4 graphically how good maintenance helps cutharm- ful emissions by as much as; 300%. "By getting the men who service cars aware of this fact and refreshing them on sound tune-up techniques we feel we can help further reduce the air pollution problems In hundreds of communities."
