Another big step toward cleaner air is being taken with the introduction of the 1970 models cars. Every new car has improved controls to reduce air pollution......
The auto industry has already produced more than a million 1970 models.....and every one is equipped with systems to further cut emissions of hydrocarbons and carbon monoxide. All new cars will meet the newest state and federal standards which require that emissions be cut approximately one-third below the allowable levels for last year's models.
As cars are produced, they are spot-checked to be sure that the anti-pollution systems are working properly. Instruments are attached to the engine and exhaust samples are taken. Information from these tests is fed to a computer for analysis. Since 1960, hydrocarbons and carbon monoxide emissions have been reduced between 70 and 80 percent in the auto industry's drive for cleaner air. Automobile manufacturers say that installing clean air equipment is one thing...keeping it in working order something else. So each new car gets a label to remind owners that the new systems work best when the engine is properly tuned.
