Basic adjustments furnisb. keys Clinics trace air pollution to its source Good things or bad things come in "threes." Three is the number of key tune-up ad- justments that can convert an average car from a polluter to a relatively pollution-free vehi- cle. The basic steps in reducing air pollution involve correcting spark plug misfire, maintaining correct fuel-air mixture and making sure timing is set cor- rectly. Through a series of Cleaner Air Clinics, Champion Spark Plug Company is instructing auto technicians throughout the nation in how to recognize and correct these laws. The clinics will reach more than technicians with the latest in- formation on controlling air pol- lution from automobiles. A two per cent rate of mis- fire can more than double the amount of unbumed hydrocar- bons. The two per cent misfire is critical since the average mo- torist cannot detect that his en- gine is acting up with that rate of malfunction. So he is no aware there's anything wrong, let alone the fact that his ear is polluting excessively. Causes spark plug misfire include worn out spark plugs, deficien- cies in other ignition compo- nents, such as points, distribu- tor caps, rotors or cables. The function of the carburetor is to mix the gasoline with air and feed the mixture to the combustion chamber. An over- rich mixture can result in 200 to 300 per cent increased un- burned hydrocarbons. Typical causes of an over- rich fuel mixture include clog- ged air filters restricting the supply of air, improperly ad- justed idle mixture and a car- buretor in need of servicing. TIMING With the new anti-pollution devices on cars, some motorists complain about loss of power. Some auto service technicians will try to compensate for this condition by advancing the tim- ing settings beyond what car makers recommend. As a result the production of unburned hy- drocarbons can increase from 10 to 30 per cent. In addition, the over advanced timing tan shorten spark plug life and damage the engine, thus in- creasing pollution even further.
