Polak, J

A study (begun in 1979 by a Technical Advisory Committee of federal and provincial environment and transport representatives and others) of in-use vehicles in Canada shows that automobile manufacturers were producing vehicles having emissions that were 30% better on the average than the regulated standard; cars in consumers' hands are very poorly tuned, particularly with respect to idle mixture, to the extent that the per cent idle carbon monoxide, carbon monoxide pollution, and fuel consumption in 1979 cars were improved 70, 36 and 4%, respectively, after tuning; emission performance makes a step function degradation during the first year of use due to carburetor maladjustment; in the absence of maladjustment, emissions degrade only slightly with age or use; and emission-oriented maintenance reduces fuel consumption. Principles for an effective emissions inspection program and recommendations for future study are discussed.
