Cleaner car engines produce less atmospheric pollution PAGE 13-SUPfLEMENT TO McHENRY PLAINDEALER-OCTGBER 3 ton have all documented CO declines. This improve­ ment has been credited by the EPA to emission con­ trol devices on a growing percentage of" cars. What goes up must come down. A decade ago, it , seemed like the nation's air pollution problems Phoenix, Ariz, reports on How theirfleet testing system saves gasoline, helps keep air cleaner The City of Phoenix has demonstrated that both fuel and money can be saved using their unique fleet emission inspection program. The following savings have been achieved. 1. More than a 10% re­ duction in light duty vehicle fuel consump­ tion in the first six months of the pro­ gram. 2. The number of vehi­ cles failing in the field and having to be tow­ ed in is down signi­ ficantly. 3. The quality of the maintenance received by the vehicles has increased substan­ tially. 4. The number of vehi­ cles being returned by the user after preven­ tive maintenance has been greatly reduced. The State of Arizona mandated that all muni­ cipal fleet vehicles receive an emission inspection once each year. The State law gives the municipal governments the alterna­ tive of having their vehi­ cles inspected by the State, or installing State ap­ proved inspection equip­ ment and conducting their own inspections. The City of Phoenix chose to install its own equipment. Each vehicle that comes in for scheduled preven­ tive maintenance receives an emission inspection be­ fore going back into serv­ ice. This inspection is given not only to minimize the emissions of the fleet vehicles but also to insure that the vehicles have been properly serviced. Plug misfire can kill'cat9 Misfiring spark plugs have long been known to cause fuel waste and ex­ cessive emissions. They can now contribute to an­ other problem -- a non­ functioning catalytic con­ verter. When plugs misfire, whether due to fouling, ignition system malfunc­ tion, or being just plain worn out, heat in the cata­ lytic converters rises. The converters, designed to change unburned hydro­ carbons and carbon mon­ oxide into harmless car­ bon dioxide and water, normally operate at 900 to 1 , 5 0 0 ° F . ( 4 8 8 t o 8 1 6 C ) . However, should spark plugs misfire severely, the temperature can be raised as high as 2,200° F„ (1,200 C>, enough to melt the catalytic agents in the converter and render the unit ineffective. Therefore, spark plugs should be changed as part of a regularly scheduled tune-up. :# WINTERIZING TUNE-UP SPECIAL!

So, the car is an ever-decreasing factor in the total air quality prob­ lem. Reports from the En­ vironmental Protection Agency and the California Air Resources Board are but two indications that cars are running cleaner. Reductions shown EPA Administrator Rus­ sell E. Train said, "Our monitoring stations are beginning to show air pol­ lution reductions that are related to our regulatory work over the past four years, especially in the areas of particulate, sulfur oxides and carbon monox­ ide control." Emissions most directly related to the automobile, carbon monoxide, have de­ clined on a nationwide basis, the EPA reports. High pollution areas in­ cluding Los Angeles, San Francisco, the states of New Jersey and Washing- California study How effective emission control systems developed by car makers have been are shown in an eight- year survey by the Califor­ nia Air Resources Board. A random sample revealed that compared with un­ controlled pre-1966 cars, 1974 models emit 83 per cent less hydrocarbons, 79 per cent less carbon mon­ oxide and 58 per cent less oxides of nitrogen. New Jersey, the only state currently conducting mandatory emissions in­ spections for all vehicles, experienced a 14 per cent drop in carbon monoxide emissions last year, the state department of envi­ ronmental protection re­ ports.
