THE ECONOMIC EFFECTIVENESS OF MANDATORY ENGINE MAINTENANCE FOR REDUCING VEHICLE EXHAUST EMISSIONS. VOLUME I EXECUTIVE SUMMARY

THE REPORT SUMMARIZES THE GENERAL OBJECTIVES, APPROACH AND RESULTS OF A STUDY CONCERNED WITH THE EFFECTS OF MANDATORY VEHICLE INSPECTION AND MAINTENANCE. THESE WERE INVESTIGATED TO ASSESS THE MOST COST-EFFECTIVE PROCEDURES FOR PERIODICALLY DIAGNOSING AND RESTORING TO SPECIFICATION THOSE ENGINE COMPONENTS HAVING SIGNIFICANT EFFECTS ON VEHICLE EXHAUST EMISSIONS. TWO CLASSES OF INSPECTION PROCEDURES WERE EVALUATED: DIRECT MEASUREMENT OF ENGINE PARAMETER ADJUSTMENTS (MALFUNCTIONS) USING CONVENTIONAL OR MORE SOPHISTICATED GARAGE-TYPE EQUIPMENT; INFERENCE OF ENGINE PARAMETER MALADJUSTMENTS OR MALFUNCTIONS FROM THE MEASUREMENT OF ENGINE EXHAUST EMISSION LEVELS (SIGNATURES) UNDER VARYING LOADING CONDITIONS. /AUTHOR/
