THE ECONOMIC EFFECTIVENESS OF MANDATORY ENGINE MAINTENANCE FOR REDUCING VEHICLE EXHAUST EMISSIONS-VOLUME 3- INSPECTION/MAINTENANCE PROCEDURES DEVELOPMENT

THE EXPERIMENTS PERFORMED TO DEVELOP, CHARACTERIZE, AND RANK MOTOR VEHICLE INSPECTION AND MAINTENANCE PROCEDURES TO MAINTAIN AIR POLLUTION EMISSION STANDARDS ARE DESCRIBED. THE EXPERIMENTAL DATA WERE DEVELOPED FROM THE FOLLOWING SEQUENCE OF INVESTIGATIONS: AN ENGINE PARAMETER FIELD SURVEY TO CHARACTERIZE THE GENERAL MAINTENANCE STATE OF VEHICLE EMISSION CONTROL SYSTEMS; A SCREENING EXPERIMENT TO SELECT THE MOST FREQUENT AND EXTENSIVE MALFUNCTIONED ENGINE PARAMETERS; AND A DEFINITIVE EXPERIMENT TO SELECT AND EVALUATE THE MOST EFFECTIVE PARAMETERS TO MAINTAIN IN AN INSPECTION AS DETERMINED BY COMBINING THE DATA FROM THE PREVIOUS TWO EXPERIMENTS. THESE EXPERIMENTS WERE DESIGNED TO YIELD A CONSISTENT SET OF DATA TO SUPPORT THE EMISSIONS MODELS. INSPECTION PROCEDURES USING BOTH DIRECT ENGINE PARAMETER AND EMISSION DIAGNOSIS WERE DEVELOPED WITH THESE DATA. /NTIS/
