VEHICLE EMISSIONS SURVEILLANCE STUDY

THE OBJECTIVE OF THE STUDY REPORTED IS TO RECOMMEND OPTIMAL PROCEDURES FOR CONDUCTING AN AUTOMOBILE EXHAUST EMISSIONS FIELD SURVEILLANCE PROGRAM. THE PRIMARY OBJECTIVE OF THE FIELD SURVEILLANCE PROGRAM WAS TO CHARACTERIZE VEHICULAR EMISSIONS TO THE ATMOSPHERE FOR SPECIFIC REGIONS WITHIN THE UNITED STATES. ALTERNATIVELY, THE DATA MAY BE USED TO EVALUATE REGIONAL DIFFERENCES IN VEHICULAR EMISSIONS SUCH AS MIGHT OCCUR BECAUSE OF DIFFERENT VEHICLE MAINTENANCE POLICIES. PROCEDURES TO BE ESTABLISHED FOR CONDUCTING SUCH A PROGRAM INCLUDED: METHODS OF CONTROLLING EMISSION MEASUREMENT STANDARDS; PROCEDURES FOR IDENTIFYING AND ACQUIRING VEHICLE SAMPLES FROM A GENERAL POPULATION; PROCEDURES FOR ESTABLISHING SELECTED TEMPERATURE STATES OF THE VEHICLE POWER TRAIN PRIOR TO EMISSIONS TESTING; AND NUMBER OF 7-MODE FEDERAL TEST CYCLE REPLICATIONS OVER WHICH EMISSIONS ARE TO BE MEASURED. /AUTHOR/
