FIELD PERFORMANCE OF EMISSIONS-CONTROLLED AUTOMOBILES

This presentation which is an update of an earlier report by the Panel on Testing, Inspection and Maintenance, analyzes the probability that the 1975-76 cars will meet the exhaust - emissions standards in actual customer use. The results of certification tests, fleet test data, component improvements, and the effects of unleaded fuel indicate that the 1975-76 vehicles will meet emission standards if correctly maintained. However, it is concluded that these vehicles will not be properly maintained. The reasons for the lack of progress in establishing regimes for enforcing adequate maintenance and the present state of the service industry are examined. Social and political attitudes are identified as causes of the inadequate maintenance. The use of unleaded fuel will reduce the maintenance which a vehicle requires. A classification of possible regimes for ensuring maintenance is presented and the three basic types are compared. Alternatives to the gasoline internal combustion engine (from point of view of maintenance requirements) are considered and none were found to offer significant advantages.
